Principles
*
1)
Every bid should have a well-defined meaning.
*
2)
We should preserve room to explore as much as possible with our good hands, and take space away from the opponents when we have a good fit and less defensive strength. Jumps should tend to be picture bids.
*
3)
The balanced hand principle: When one hand has defined itself as balanced with a limited range of values, the other hand is the captain, and the balanced hand should do its best to stay out of the way. This principle is a subset of one that I discovered, "the less-defined hand principle". Using transfer bids is one of the very best ways of observing these principles.
*
4)
It is better to slightly lie about strength, if it enables you to give an excellent description of your shape. That is, if you can hope to give a much better description of your hand, you should be willing to either overbid OR underbid by a small amount.
*
5)
Anchoring the auction as early as possible will virtually always lead to a more comfortable auction. This allows us to share captaincy, which enables both players to offer meaningful input as to where we belong. Bids that allow us to show trump support are especially useful. Support partner as soon as reasonably possible.
*
6)
When no bid fits particularily well, we should tend to "default" to a bid that is both cheaper to show, and suggests a reasonably attractive strain.
*
7)
Singletons and voids are often crucial features of a hand. We need to be able to show them in as many auctions as possible.
*
8)
When there is doubt over the meaning of a bid, we should tend to assume natural rather than artificial, non-forcing rather than forcing, and telling rather than asking.
*
9)
Most bids of 2NT in competition are for takeout
*
10)
Return to suit is weakest in competition
*
11)
New suits in competition by either hand are natural and competitive when double and cue are available for stronger hands.

Summary for online opponents:
*
a)
1NT 12-14, 1M usually 5+, 2♦ = 3-suited 11-14, any shortness. 3rd from even, low from odd vs suits, 4th from an honor vs NT. Rusinow vs both. UDA, standard count, special 3rd hand echo vs NT. Our CC: https://tinyurl.com/doug-adam-cc

Mnemonic for Adam -- This is the opposite of numeric: higher bids show lower numbers.

Alternatively, lower bids are short in the lower ranking suit.

1.5)
4X = Natural, 544 with short ♢ (4♢ = 4-4-1-4), too strong for 3N

4♢ to transfer to 4♡ (now 4♠ is RKCB)

3)
4♡ is a signify

Similar when opener pre-accepts after a transfer to 2♠, though without the 4441 possibilities.

With a five card Major responder will transfer to it over 3N, so he should have at least a solid game force.

a)
3♡ = Asks

i)
3♠ 4144

1)
This wrong-sides 4♠. Tough! They may be best off with a trump lead anyway.

Can't be worth worrying about, since this auction has never come up.

Competitive auctions
V
a)
They double 1N
V
i)
They double for penalties
V
1)
Tame Runouts:
>
1.1)
Pass To Play
XX To Play
2m To Play, could be other hands
2M To Play
2♣ followed by redouble = 4441 with 4♣
2♢ followed by redouble = 4-4-4-1
2♣ followed by 2♢ = 4♢ + 4M
2m followed by 2♡ = 4♡ + 4♠
With 4-4 in the Majors responder can start with either minor. He may want to bid his 3-card minor in case he's not doubled, or he may want to bid 2♣ to make it easier for the opponents to come in.
4432 with four clubs: Guess what to do -- no system bid is available. Consider treating it as a 4441. More science is possible here, for instance:
>
1.1.1)
1N (X) 2♣! (X)
P P 2♢ (X or P)
*
Opener can bid 2♡ with 4♡ but not 4♠, and XX with equal length in the majors, say 3=3=2=5 or 4=4=3=2. That can help if responder is groping with something like 4-3-2-4 or even 4-3-3-3.
>
2)
XX followed by double (by either player) is for penalties
>
2.1)
Pass followed by double (by either player) is for takeout
*
2.1.1)
Same over balancing doubles
*
3)
2M = Natural, to play
>
4)
2N
*
4.1)
minors signoff, or any 2-suited GF
*
5)
3X = Preemptive
>
ii)
They double artificial
*
1)
Our structure is the same as if it were a penalty double, except possibly for cue-bids.
*
2)
If we bid a suit they've promised four or more of it's a cue-bid showing shortness.
>
3)
If opener doubles a "pass or correct" bid it's for takeout
*
3.1)
e.g. 1N (Dbl) P (2♣ pass or correct) Dbl
V
b)
They overcall directly
V
i)
They overcall 2♣ natural or semi-natural, Including 2♣ = ♣ + another suit
*
1)
Dbl = Neg, usually at least two clubs
*
2)
3♣ = short clubs GF
V
3)
Everything else = Front of card
*
3.1)
2♠ followed by a bid showing clubs is unchanged, exposing the possible psyche or (more likely) misexplanation.
V
ii)
They overcall 2♣, any single suiter, or multiple possibilities
*
1)
Same as if 2♣ were natural, except that 3♣ is a signoff with both minors, as over a 1N opening.
V
iii)
They overcall 2♢, 2♡, or 2♠ natural or semi-natural, Including 2♢ = ♢ + another suit
>
1)
Dbl = Negative, usually at least 2 cards in their suit
*
1.1)
Opener is expected to pass with four trump
*
1.2)
Dbl followed by a cue shows 4OM balanced with no stopper
*
2)
2X = Natural, to play
V
3)
2N+ = Transfer Lebensohl:
V
3.1)
2N forces 3♣, similar to old fashioned lebensohl
*
3.1.1)
2N followed by a suit lower than theirs is a signoff
>
3.1.2)
2N followed by a suit higher than theirs shows clubs with the suit bid
*
This is still true if they bid over 2N, e.g., 1N (2♡) 2N (3♡) P (P) 3♠ A double would show shortness w/o 4♠.
>
3.1.3)
2N followed by a cue-bid is shortness without 4OM, GF
>
i.e. both minors, 5-4 or longer
*
Or ♣ with short ♢ over 2♢
*
3.1.4)
2N followed by 3N shows a stopper. It could be as little as Jxx, but opener always passes. With Qx responder guesses whether or not to show a stopper based on the rest of his hand.
*
3.2)
Higher bids are invite+ transfers, and we transfer through their suit.
>
3.3)
3♣ shows diamonds, invite or better
*
3.3.1)
When followed by a cue-bid it shows shortness
*
3.4)
3♢ shows hearts, invite or better (but spades when their suit is hearts)
*
3.5)
3♡ shows spades, invite or better (but clubs when their suit is spades)
V
3.6)
3♠ shows clubs, GF, when their suit is hearts
*
3.6.1)
3N = I don't like my hand for clubs (confirm with Doug)
*
3.7)
A cue-bid shows shortness with exactly four of the other major, or at least one major over diamonds.
>
3.8)
3N denies a stopper and denies shortness
*
3.8.1)
Without a stopper of his own opener bids naturally
*
3.9)
4m undefined
*
3.10)
4M, 5m = To play
*
3.11)
We have no way to show 5-4 or longer in the minors with shortness in the other major. Tough!
>
iv)
They overcall with a transfer or Astro, or, more generally, with a bid at the 2-level that promises a known higher ranking suit and is ambiguous about other suits
*
1)
We bid as over natural overcall, including transfers at the three level
*
2)
Dbl = Neg, at least two cards in their anchor suit
V
3)
Cue (accept the transfer) = short in their suit, competitive, often 4441
*
3.1)
With a GF we'd cue at the 3-level, either directly or after going through 2N
>
4)
Pass followed by Dbl = penalty double of overcaller's first suit
*
4.1)
Takeout of the suit doubled if they’ve bid a new suit. Opener will tend to pass unless short.
>
v)
They overcall with a bid, one possibility of which is a transfer
>
1)
Same defense as to transfers, except that a cue-bid is natural and we can transfer into their suit at the three-level.
*
1.1)
That means we have no way to show shortness with a cue-bid. That's OK! We can double, takeout of their anchor suit, and then not sit if opener doubles their anchor suit at the two level.
*
2)
Except that if they're overcalled 2♣ then we play front of card.
V
vi)
They overcall 2♢, Multi
*
1)
Front of card, starting with Dbl = ♡
V
2)
Pass followed by Dbl by either player is for takeout
*
2.1)
1N (2♢) P (2♡) X = T/O
*
3)
Pass followed by a cue at the 3-level is Stayman with shortness
V
vii)
They bid 2m to show both majors, e.g. Landy, Ripstra, Capelletti
V
1)
We use the Kaplan defense:
*
1.1)
Dbl = Want to penalize at least one major.
>
1.2)
Pass followed by double = negative: opener passes with four trump. Could also be good balanced: Manfield "I've got a secret"
*
1.2.1)
If opener pulls this double to 2NT it's natural
*
1.3)
2M = stopper, invite or better
*
1.4)
2N = Natural, minor suit oriented because no attempt to penalize opps
*
1.5)
3m = competitive, limited by failure to double or cue
*
1.6)
3M = SPL, could be, say, 6-3 in the minors.
*
1.7)
3N = To play -- does not show or deny stoppers
>
viii)
They overcall 2♡=Majors
V
1)
Double = negative, passable: promised at least a doubleton in each Major
V
1.1)
(2S)
*
1.1.1)
Opener’s X of 2S is for penalty. Responder’s shows extra high cards.
*
1.2)
Pass followed by a double of 2♠ = penalties
*
2)
2♠ = Transfer to clubs with pre-accept
*
3)
2N = Transfer to diamonds with pre-accept
*
4)
3♣ = both minors competitive

5)
3♢ = both minors forcing
*
6)
3M = SPL

7)
3N = To play
V
ix)
They overcall 2N
*
1)
3♣ = Stayman (no Smolen ever after 1N)
*
2)
3d, 3H = Transfer, INV+

3)
3S = ♣
V
x)
They overcall 3♣ (also over 2N)

1)
3 suit transfers, INV+
V
xi)
They overcall 3♢ (also over 2N)
*
1)
3H = S INV+, 3S = H GF
>
xii)
Negative doubles through 3♠
*
1)
2+ trump at the 2 level, 1+ trump at the 3 level.
V
xiii)
They overcall 4m
*
1)
4N is to play with length, usually 6 cards, in the other minor.
V
xiv)
They overcall 4M
*
1)
4N is for takeout
V
c)
They double Stayman showing clubs
*
i)
Redouble is natural with 5 decent clubs
*
ii)
2d is natural, does not deny a club stopper
>
iii)
2M neither shows nor denies a club stopper
*
1)
Now 3♣ asks for one
*
iv)
3♣ (rare) shows both majors with a maximum. Now responder can play the hand.
V
d)
They double Stayman showing cards
*
i)
Opener should only pass or redouble (natural with good clubs) -- they may have just made a big mistake.
*
ii)
Responder's double = PEN
V
e)
They balance with a natural bid (4 cards or longer)
*
i)
Our doubles of natural bids are for takeout by either player
*
f)
Opener's doubles of artificial minor suit bids are for business (as above)
V
g)
They double Jacoby
*
i)
If opener completes the transfer he promises at least three trump. Passing shows a doubleton trump.
V
ii)
Responder's redouble is a retransfer
>
1)
Now if responder bids a new suit it's a signoff, to play a 5-3 or better instead of a 5-2.
*
1.1)
Probably best not to bid the doubler's suit if they claim the double is natural!
*
2)
Responder's other bids are unchanged, except for a cue-bid which is undefined but probably a 544 GF if they claim the double is natural.
V
h)
They bid over Stayman
*
i)
Both Opener's and Responder's doubles are for penalties
>
D
Minor suit openers
*
1)
With 4-4 in the minors we normally open 1♢

With 4-5 we normally open 1♣. 1d is possible with strong diamonds and weak clubs.
V

3)

i)
2♣ forces opener to bid 2♢. Responder's rebids between 2♡ and 3♢ are
invitational. Thus:
Pass to play 2♢
2♡ or 2♠ = 4-card suit, only 4 diamonds, not forcing
Opener should consider raising with 4-card support, even with a minimum.
2NT is a raise to 2NT with 5 or more diamonds.
3♣ is invitational
3♢ is 6+ diamonds invitational
3♡ and 3♠ show a singleton or void with 6 or more diamonds, GF.
3NT is a mild slam try with long diamonds.
4NT is a serious slam try with 5 or more diamonds.
*
ii)
2♢ is a GF. Opener bids his cheaper 4-card major if he has one, otherwise normally 2NT. Subsequent bidding is all natural, subject to responder's having denied certain hands.

1)
2♣ forces opener to bid 2♢. After 2♣ responder's bids are as follows:
*
1.1)
2♡ is invitational with 5 or more hearts and an unbalanced hand.
2♠ is invitational with 4-4 in the majors.
2NT is invitational with 5 hearts, balanced.
3♣ is invitational, with club support if partner opened 1♣, otherwise probably 4♡ and 6♣.
3♢ is invitational, probably 5-5 if the opening was 1♣.
(With an invitational strength hand with 5-5 in hearts and clubs after 1♢ - 1♡ - 1NT, responder bids 2♣ and follows with 2♡.)
3♡ is invitational with 6 or more hearts.
3♠ and 3NT are undefined. If Adam bids 3N it means he's 5332 and offering a choice of games, and he forgot he should start with a transfer.
You (Adam) don't want to know about 3♠ and 3NT yet (single-suited slam tries with a singleton or void somewhere, depending upon the bid).
4♣ (3M+3) shows a self-splinter, short in ♠, with good trump (3 of the top 5).
4♢ and 4♡ show slam tries with 6 or more ♡ and no shortness. 4♡ is a mild slam try, typically no more than 15 HCP, and 4♢ is a serious slam try. Both show good trumps. As a rough guide 'good trumps' means at least three of the top five. Opener with a doubleton honor should not be concerned about the possibility of two trump losers. Responder should pay particular attention to the jack and ten, which will not show up with RKCB.
>
2)
2♢ is a transfer to 2♡, which opener must accept. Afterward responder bids 2♠ to show 46 invitational, and higher bids to show GF with five or more hearts.
*
2.1)
2NT is a balanced GF, but concern about notrump, generally a very good five-card suit.
*
2.2)
3♣, 3♢ are natural, GF.
>
2.3)
3♡ is GF with six broken hearts, offering a choice of games.
*
2.3.1)
This bid is used for hands that don't know whether to play in 3NT or 4M, holding a six-card major. Usually with a six-card major, you would just bid 4 of the major with no slam interest. This bid allows you to avoid 4M, when 3NT would be better. I don't think that it needs a precise definition, but I think that 'lacking three of the top 5 honors in the suit' would be a good choice, if we made one. Of course, opener could cue bid on the way to 4M with an appropriate hand.
*
2.3.2)
Opener will choose 3N when he is concerned about going down in 4♡ with trump losers but plenty of tricks outside.
*
2.4)
3NT is a pure choice of games, balanced hand and moderate hearts.
*
2.5)
Jumps to 3♠ and 4m are self-splinters without three of the top five trump honors.
*
2.6)
4♡ is a balanced slam try with 6 or more decent hearts, but not three of the top five trump honors.
>
3)
2♡ is a GF, asking opener if he has four spades, but not necessarily showing four spades. Opener bids 2♠ with four, and 2NT otherwise.
*
3.1)
Responder's follow-ups are natural, a 3♡ bid over 2N shows 4-5 in the majors, GF. Opener's 3♠ is last train, concerned about the 4th suit. Responder's 3♠ shows 5-6. Responder's 3N over 2♠ is a 4-4-3-2 choice of games, with a doubleton in opener's minor. Responder's 3m denies a 5th heart unless he's 45(04).
*
3.2)
Responder might bid 2♡ without four spades if he had a balanced hand
with slam interest, typically with four card support (five card support if 2452) for opener's minor.
*
4)
2♠ is invitational with 45 in the majors.
*
5)
2NT is invitational with four hearts (and not four spades).
*
6)
3♣ is to play.
*
7)
3♢, 3♡, and 3♠ show GF with support for m. 3♢ shows shortness in om, 3♡ shows short ♠ and 4♡, 3♠ shows short ♠ and 5♡. Responder can hold 4 or 5 m.
*
8)
4♣ and 4♢ are self-splinters showing singletons with good trump (3 of the top 5).
>
ii)
1m 1♠ 1N
*
1)
Transfer checkback after a 1♠ response is similar to that after a 1♡ response.
>
2)
2♣ is a puppet to 2♢, showing either a diamond signoff, some invitational hand, or a slam try (or better) with a long spade suit. Responder's bid over the forced 2♢ is invitational and natural if it is 3♠ or lower.
>
2.1)
2♠ shows an unbalanced invitation.
*
2.1.1)
2N = Maximum, no spade fit
*
2.1.2)
3X = spade support with values in X
*
2.2)
2NT shows a balanced invitation with 5 spades.
*
2.3)
3N and 4♣ do not exist (yet -- see 1m 1♡ 1N above)
*
2.4)
4♢, 4♡ and 4♠ are slam tries, analogous to those over a 1♡ response (♡ self-splinter 3 of 5, BAL strong & mild INV good trump, )
*
3)
2♢ is a transfer to hearts. Unless responder is 6-4 in the majors, he has either a signoff or a game force, NOT an invitational hand. Opener bids 2♠ over 2♢ unless he has more hearts than spades, in which case he bids 2♡. If responder bids 2♠ over 2♡, he has a game-invitational 6-4 hand. Otherwise, his bid is a natural game force.
*
4)
2♡ forces opener to bid 2♠ (i.e. a transfer). Responder has a signoff or a game force. Over opener's forced 2♠, responder's bids from 2NT through 3NT are natural GF, and all show at least 5 spades. 2NT suggests a good spade suit, and some doubt about NT. 3♠ shows a broken 6-card suit, and interest in playing in notrump. 3NT is a pure choice of games, some 5332 and normally a moderate suit. Jumps show self-splinters without 3 of the top 5 trump honors.
*
5)
2♠ is a game force with EXACTLY four spades. Opener is required to bid 2NT, and responder will describe his hand further. He would typically have a balanced hand, perhaps with support for opener. It is possible that if the opening bid was 1♢, he might have long clubs, but was not good enough to bid 2♣ initially.
*
6)
2NT is an invitational raise with no major suit interest.
*
7)
3♣ is to play.
*
8)
3♢, 3♡, and 3♠ show GF with support for m. 3♢ shows shortness in om, 3♡ shows short ♡ and 4♠, 3♠ shows short ♡ and 5♠. Responder can hold 4 or 5 m.
*
9)
3NT and 4♠ are signoffs.
*
10)
4m is a self-splinter with good spades (nominally 3 of the top 5).
>
11)
4♡ is a natural slam try, 6-5-1-1.
*
11.1)
4N over 4♡ is RKCB for hearts

*
1)
It usually denies a 5th trump, but 1♣ 1♠ 2♢ 2♡ could have a 5th spade, perhaps planning on passing if opener bids 2♠
*
2)
After a waiting bid responder can sign off in ♢, e.g., 1♣ 1♠ 2♡ 2N 3♣ 3♢. This is rare -- responder needs six good diamonds and short clubs.
*
ii)
When 2N is more expensive than the 4th suit it's natural and shows 8-11 HCP, or 15+

balanced))

7)
2♣ = inverted raise
V
8)
2♢, 2♡, 2♠ = weak jump shifts - 3-5 HCP, at least 3 HCP in the suit bid.
*
8.1)
A jump to 2M by a PH is a hand that was not suitable for a weak 2, for some unspecified reason.
*
9)
2NT = weak hand with 5+ clubs (2-5 HCP)
>
10)
3♣ = 6-8 HCP with 5 or more clubs -- a "mixed" raise.
*
10.1)
The reason for the switch is so that opener becomes declarer in 3NT when he has a good hand, and responder has some values.

ii)
A single raise is standardish: 4 trump, fewer than 9 HCP

1)
Opener's 2NT bid shows at least a good 17 count.
*
iii)
A jump raise is preemptive: no game opposite 15-17 balanced
*
iv)
A jump shift is strong by an UPH and fit showing by a PH.

v)
A cue-bid over an overcall shows the same hand as an inverted raise, and our structure is the same.
>
vi)
Opener's cue-bid of his LHO's suit is a reverse, in principle the same kinds of hands it could have been without the overcall. e.g.,
>
1)
1♣ (1♢) 1♠ (P)
2♢
*
1.1)
Shows ♢ values and promises a rebid.

1.2)
Responder rebids as over a reverse.

2♡
*
2.1)
Shows ♡ values and promises a rebid.
*
2.2)
Similar to our reverse structure, but since 2♠ is always available 2N is natural, 8-11 or 15+.
>
vii)
Opener's cue-bid of RHO's suit shows a hand too strong to jump rebid his own suit
>
1)
e.g. 1m (P) 1♡ (1♠)
2♠
*
1.1)
Responder's 2N shows a stopper and is FG.
*
1.2)
Opener can pass responder's return to 3m, which denies a stopper
>
viii)
Strong NT double
*
1)
When responder has shown values opener's first double shows a strong NT or better. His pass below two of responder's suit shows an unbalanced hand.
*
2)
If they bid two of responder's suit opener must double with a strong NT, whether or not the cue-bid is natural. Opener will not double a natural cue with a singleton in responder's suit. His pass over a natural cue implies a singleton, with or without extra values, though he could be stuck with something like 5422.
*
3)
When an opponent has bid above two of responder's suit opener is allowed to pass with a minimum strong NT. So, although the pass at that level suggests an unbalanced hand, it does not guarantee one.

Third seat openers are hands that would at least CONSIDER opening the bidding in first or second seat (though perhaps only briefly). Any weaker than that, and we either open with a weak two-bid or pass. Thus, AQT9x xx xxx Axx is a 1♠ opening, but change the ace of clubs to the king, and we open 2♠.
A light opening bid will always be based upon a good suit, and is
likely to be able to rebid the suit comfortably, or pass any response.
With AQT9x x xxxx Axx opener must pass a 2♡ response, since 2♠ would be forcing.

RKCB -- 0314

a)
If they double 4N then XX is to play, pass allows the asker to XX naturally or to show his key cards, and bids are unchanged.
*
i)
Over XX the asker can choose to show his key cards instead of sitting.
*
b)
Over a queen ask a return to our trump suit denies the queen.
*
c)
5N over 4N shows two keys cards and a void

d)
6x over 4N shows an odd number of key cards and a void in x
*
e)
4N followed by 5N asks for specific kings

i)
Doug does not want to have an agreement. But it does no harm, since it's what we might do without discussion.
V
ii)
If they double the response to RKCB:
*
a)
Opener's relay asks for the trump queen, ignoring the double.
V
b)
Opener's pass denies a control in their suit.

1)
Now responder signs off if he also lacks a control, redoubles with a control but no trump queen, and bids a slam with both (or 5N with the trump queen and the king of their suit.)

ii)
After the initial response:
*
1)
Over a 1 or 2 step response, the cheapest bid that’s not our trump suit asks for the trump queen. The next step that’s not our trump suit asks for specific kings.
*
2)
A new suit that's not asking for the trump queen or specific kings asks for third round control.
*
3)
5N replaces the king ask -- it asks for third round control in the suit of the king ask.
*
4)
We cannot stop in 4N.
>
iii)
If they double, XX is to play, pass shows no control, and with a control responder shows key cards.
*
1)
Opener's XX asks for key cards again
*
2)
Over a XX opener shows key cards himself if he's not willing to sit
*
iv)
If 4N is one of the asking steps then it remains asking, not an offer to play.

7)
When 4N is natural and invitational an acceptance is forcing to 5N, per Marty Bergen's suggestion.

8)
Cue bidding style

a)
First cue shows extra values
*
b)
Cue is response is not necessary with minimum values or no slam interest
*
c)
We cue first or second round controls up the line
*
d)
First cue is usually not shortness
*
e)
If partner signs off over a cubed then 4N is not Blackwood
*
f)
4N is still Blackwood after two cues
>
g)
When they double our control-showing cue
>
i)
Pass = worried about suit — no control but extras.
*
1)
The cue-bidder will normally redouble with first-round control.
*
2)
The redouble shows definite control and ask for further cues. It tends to deny enough extras to cue below our suit or go past our suit. A new suit by the cue-bidder is extras without worry about the doubled suit.
*
3)
If the cue-bidder has the unprotected king he must use judgement on continuation - perhaps it can be be played from his side.
*
ii)
Sign-off = no control (not even queen) and no extras.
*
iii)
New suit = not worried about the doubled suit and extras (holds first or second round control or queen)
*

When we’ve agreed a minor, four of a major where we’ve shown 5+ is natural, an offer to play
>
I
2♢ Opening
>
1)
Description
*
a)
The 2♢ opening shows a 3-suited hand, any 4441 or 5440, of minimum opening strength, typically 11-14 HCP.
*
b)
Strength I think of the minimum as being that of a weak notrump. 12.0 is a possible opening, and 12.5 is a mandatory opening. So open 2♢ with Kxxx --- Axxx KT9xx (14.05); pass with Qxxx Qxxx x AQJx (11.4). A 5440 with 15 HCP is normally too strong for 2♢. Something like KQxx x Axxx KQxx would be a maximum 2♢ opener.
Depending upon the vulnerability and position, you might choose to open 2♢ with slightly less strength as the best tactical maneuver.
*
c)
Five card majors: A 2♢ opening is possible when holding a five card major, but there is some danger of missing a fit in the suit, so it is definitely NOT automatic to open 2♢ instead of 1M, especially if the suit is good. 2♡ is a common response to 2♢, so the danger of missing a heart fit is only moderate. When opener has five spades and four hearts, it is almost always best to open 1♠, unless the spades are really bad. For example, Txxxx KJxx --- AKJx.
*
d)
Singleton honors A singleton king is a significant flaw. It gets 0.8 on the Kaplan count, which might be about right for suit play, but is a significant understatement for notrump. A singleton queen can cause you to misjudge also, but the degree is not normally as great. A singleton ace is probably worth about three points rather than four.
If you have K AQJx QTxx Jxxx, I don't know what the best bid is. My guess is that pass and 1NT are the leading candidates. Perhaps I'll find time to run a simulation some day, so I will have a better idea.
>
2)
Responding with a weak hand
*
a)
With less than game invitational values, responder will bid 2♡, 2♠, or 3♣ as 'pass or correct'. Opener will nearly always pass with length or correct to the NEXT STEP with shortness in responder's suit. Thus, opener bids 2♠ over 2♡, 2NT over 2♠, or 3♢ over 3♣ if short in responder's suit.
Responder then places the contract. However, sometimes responder will be surprised that opener's shortness was where it was, and can offer a game invitation by jumping. Additionally, responder can invite a game if his correction is to a suit that he could have bid at a lower level.
For example. Jx AKT9x xx Jxxx. Partner opens 2♢. He his highly likely to be short in either clubs or hearts. If he is short in hearts, then you want to play a club partscore. If he is short in clubs, then game in hearts is a lively possibility. So bid 3♣. If partner corrects to 3♢, you can bid an invitational 3♡. (If you think this hand is too strong to invite, then you could weaken it a touch, but you get the idea).
I actually had this hand come up in the IMP game. Partner passed 3♣ and then RHO (Harold Feldheim) balanced with 3♡. What a nice development! My penalty double ended the auction.
Another possible call with a weak hand is pass. This could be either long diamonds, e.g., xx xxx KJTxxx Qx. Or possibly you might judge that partner is short in your long suit, and be able to determine that diamonds is your likely best spot. e.g., Jx x Kxx Qxxxxxx.
It is not unusual to respond 2♡ with a three-card suit. Common patterns are 4333 and 5332. With two four-card suits, you should not bid a lower three-card suit, even if you have to go to the three-level. If the hands fit reasonably well, then every additional trump results in about a trick and a half more. So, it is worth being a level higher to play in a longer fit. So with xx Kxx Qxxx Qxxx, bid 3♣ in response to 2♢, rather than 2♡.
If an opponent doubles 2♢, responder's pass is to play opposite length. Opener passes with length, and redoubles with shortness.
To sign off in clubs responder can bid 3♣, then 4♣, or try passing 2♢ and correcting to 3♣ if doubled.
>
b)
Opener's bids over signoffs
*
i)
With a maximum (14 if 4441) and a fit, the 2♢ opener is allowed to 'raise' by bidding his shortness. (Over a 2♡ response, with shortness in spades, he bids 2NT). Over opener's rebid, responder places the contract, perhaps in a new suit. For example: Qxx xx Kxxxx xxx. 2♢ - 2♠ - 3♣, responder bids 3♢. With a stronger hand, he could bid an invitational 4♢.
*
ii)
Opener should be cautious about raising a 2♡ response, unless he has five-card support. A two spade response will be made on a 3-card suit much less often, so opener can be more aggressive with only 4 spades than he would be with four hearts over a 2♡ response.
>
3)
Responding with a jump to 3X
*
a)
3♢, 3♡, and 3♠ in response to 2♢ show invitational hands with a good six-card or longer suit. Opener always accepts with length, bidding his shortness along the way. With the more likely shortness, he accepts with a maximum, paying special attention to his controls and, to a lesser extent, the size of his singleton.
*
b)
3N is to play
>
4)
Responding 4m
*
a)
Preemptive, with a weak 2-suiter. Opener is expected to pass or correct.
>
5)
Responding 4M, 5m
*
a)
To play opposite presumed shortness
>
6)
Responding 2N
*
a)
2NT is the strongest response to 2♢ (whether or not an opponent intervenes). Opener indicates his shortness by bidding the suit BELOW his short suit (whether that shortness be a singleton or a void). However, if his short suit is clubs, it would crowd the auction for responder to ask further with 4♣. Therefore, if opener has a club void, he shows it directly in response to 2NT. 3NT shows five diamonds, 4♣ shows five hearts, and 4♢ shows five spades.
After opener's rebid of 3♣, 3♢, or 3♡, responder can invite by bidding a suit opener has shown or force to game while asking for a 5-card suit by bidding opener's shortness (next step). (If responder wants to play game in opener's short suit, he bids it!) Opener answers in steps (with 3NT always denying a void). The first step shows five of the lowest possible ranking suit (always clubs), the second step shows five of the next highest possible suit, and the third step shows five of the highest ranking suit. The reason for this structure is that a long minor is far more likely than a long major (especially spades), and we thereby save space.
After asking for a five-card suit (or getting a response to 2NT of 3♠, 3N, or 4♣, TRANSFER bids, and other special calls apply.
4♣ asks opener about the strength of his hand. Opener answers in steps, with the first step (4♢) showing a minimum, and the third step (4♠) showing a maximum. 
4♢ is a transfer to hearts (if opener has shown the suit) or else key card Blackwood for clubs (if opener has shown short hearts).
4♡ is a transfer to spades (if opener has shown spades), or else key card Blackwood for clubs.
4♠ is keycard Blackwood for diamonds (or clubs, if opener has shown short diamonds). 
It is virtually impossible for opener to have NO key cards. Therefore, one key card is assumed in the responses when four steps are not available. The first step shows 1, second step 2 without the queen, third step, 2 with the queen. With three key cards we will be in slam, and opener bids the fourth step to show three key cards without the trump queen.
After a transfer to a major, the NEXT STEP is key card Blackwood for that suit, with the standard responses (0 or 3; 1 or 4, etc).
The second step is a short suit slam try in opener's lower side suit, and the third step is shortness in opener's higher side suit.
The fourth step is a 'serious' slam try with no shortness, and the fifth step, 5M, is a mild slam try with no shortness.
NOTE: If opener bids 3♠, 3N, or 4♣ in response to 2NT, the transfer bids apply. You have to be on your toes, or you could end up much higher than you would like, or play in a transfer bid.
If responder jumps to 5m over opener's first rebid, it is a mild try for six, on general values. Doug once reached an 80% slam when he bid 6 on this sequence, and once missed a good 6 when he passed holding just a bit less than a maximum. To sign off in game, responder must first ask again.
>
b)
Void showing responses
*
i)
If opener bids 4♣ over the first or second ask then we lose our size ask, but the transfer bids and minor suit key card asks still apply.
If opener bids 4♢, responder's 4♡ is natural and non-forcing if opener has shown hearts, otherwise it is a transfer to spades.

Anti-lead directing double

Definition, for reference:
A double of an opponent's bid in a suit mentioned in a natural sense by your side, at a stage in which it is clear that you would no longer wish to contest the auction. This sort of double sends the message: "I would be happier if you led some other suit; my holding in the suit I am doubling is unusually weak." If you use this treatment, you must alert your opponents to the ramifications of your (and partner's) failure to double.
*
ii)
We play this only if it's a suit bid by the doubler, and only in a suit that would normally have shown at least five cards, and only when we know it's not our hand.
The doubler must be a preemptor whose partner has passed, or must have passed at least once before doubling.

Doug's article on Honor Leads Against Notrump
*
a)
The system of honor card leads versus notrump commonly in use today have several deficiencies. The following suggestions go a long way toward remedying those shortcomings, providing the defenders with ample opportunity to send and receive the information needed to conduct a successful defense.
Traditionally, the lead of the ace against notrump shows a powerful holding in the suit and asks partner to unblock his king, queen, or jack; otherwise he gives count. Thus, the ace would be led from AQJT(x), AKJT(x), or AKQT(x). The opening leader might also judge to lead the ace from the above honor holdings when he lacks the ten but has a five card suit, and almost certainly when he has a six card suit.
It is easy to see that it is unnecessary to require partner to unblock the king when the ace is led. Unless the opening leader strongly suspects that a singleton king is outstanding or has a certain entry in another suit, he will lead a lower honor from AQJTx. This will enable him to maintain communication with his partner when an opponent has the king. If partner has the doubleton king, he will unblock it at trick one and return the suit. With three or more cards headed by the king he will encourage. The defenders should have little trouble running the suit.
There is one other important holding in addition to AKJTx and AKQTx where we would like to see partner unblock an honor for us. That is KQT9x. The modern treatment is to lead the queen to "demand the play of the jack". This creates a possible problem when partner has the ace without the jack, places declarer with the king, and thinks that we need to win tricks quickly in another suit. (See RATS, April 1974 Bridge World).
Another problem occurs when partner has neither the ace nor jack, assumes we are leading from QJ, and plays an attitude signal based on his failure to hold the king or ten. For example,
A43
KQT95 (a) 82
(b) 862
(a) J76
(b) J7
If using standard attitude signals, on our lead of the queen, partner will play the deuce from both 82 and 862, leaving us with little idea whether to continue with the queen or switch to anther suit.
What we want is for partner to unblock the jack or else give count. But wait! That is exactly what we want partner to do when we have AKJTx or AKQTx. Note that the only high honor in common between AKQTx, AKJTx, and KQT9x is the KING. Thus, if we lead the king from each of those holdings, partner will play the card that gives us the information we need. Additionally, if he does hold the ace, he will know what we have and play accordingly (normally winning the ace and returning the suit). Therefore, it is superior to use the king as our "strong" lead, asking for the unblock of the queen or jack, or else count.
The king is the "standard" lead from AKTx. Partner would encourage with the queen, and we can continue the suit. Unfortunately, since the king is also the standard lead from KQTx or KQx, partner would also encourage when holding the jack, giving us a problem. Having reassigned our strong honor lead from the ace to the king, we have freed the ace to show the king and ask for an attitude signal. The removal of the ambiguous king lead puts us in better position to judge how to continue successfully should we have AKTx.
From AKxxx we would nearly always lead a low card on opening lead. If partner has the defender's entry, it is vital for him to have a card to lead to our established suit when he started with a doubleton. However, should we hold AKxx, it is not necessary to lead low at trick one in order to maintain communication. If we lead the ace, the appearance of dummy and partner's signal can guide us to continue with a low card at trick two if that seems appropriate.
Leading low at trick one does gain when partner started with QJx, and either declarer or dummy has four cards in the suit, and it is better if partner has Qx or Jx. Additionally, the low lead gains when dummy has the queen (1/3), partner the jack (1/3), and declarer or dummy the ten (2/3) for a combined chance of 2/27 or about 7%. However, dummy needs at least three cards in the suit for the low lead to gain, further reducing the times when leading low works better.
Leading high gains when either declarer or dummy has the doubleton queen and partner the jack. It also gains if partner has the ten and an opponent the QJ doubleton or if partner has JTx and declarer the queen. Best of all, partner could have five of the suit, and the entire suit could be run at once. Leading high can gain by saving a tempo when the appearance of dummy and partner's signal make it obvious that a shift is needed. The high lead will also avoid a potential disaster when dummy has Jxx and partner Q9x. It would be a shame to lead low, have partner play the nine, and declarer win the ten. Finally, leading high from AKxx shows partner where our honors are, giving him a clearer picture of the defensive assets.
Assuming that we lead the ace from AKxx, let’s look at how third hand should signal. Assume that upside attitude signals will be used. If dummy has Qxx(x) or Jxx(x), third hand's signal asks for partner to continue with a low card. However if dummy has any doubleton or three cards lacking the queen or jack, there is a choice about how the opening leader should continue when he receives an encouraging signal. Logically, an encouraging signal could either show the queen, or alternatively, it could show sufficient length that declarer's queen is doubleton.
I suggest that third hand's encouraging signal ask for the continuation of king and another card in the suit. This enables the defense to run the suit in the critical case when third hand has five cards, and it works well when the suit is 4-4 with declarer having a doubleton. If third hand has four (or five) to the queen, he is happy to have the opening leader continue with the king and another. It is only when third hand has specifically three to the queen that he would prefer opening leader to continue with a low card. In that case, third hand should normally discourage if it appears that he will gain the lead at some point. On the other hand, if dummy has three small and it appears likely that partner will have an entry, third hand should encourage.
Should dummy have a singleton or void in the suit led, the odds change. Declarer is rather unlikely to have a doubleton queen leaving the suit divided six-two. It figures to work better to have third hand's attitude signal show the queen, and to suggest that opening leader continue with a low card in the suit.
With the ace and king leads accounted for, it is time to move down the line. From KQx, KQTx, or KQ9x we do not want partner to unblock the jack or ace at trick one, so we cannot lead the king. Thus, we much select the queen, asking for an attitude signal. We would like for partner to encourage if he has the ace or jack and discourage otherwise.
From QJ9x we want partner to encourage when holding the ace, king, or ten; else discourage. If we adopt the queen as our standard lead from this holding, partner will discourage if he holds the ten and nothing higher. Futher, if declarer has the king, partner might have difficulty discerning whether we led from KQ or QJ. That's no good! Let's lead the jack instead, showing the queen and asking for an attitude signal with the ace, king, or ten. Hey! This looks like Rusniow.
The lead of the queen shows the king and asks for attitude with the ace or jack. The lead of the jack shows the queen (and possibly the ace or king) and asks for attitude with the ace, king, or ten. The ten shows the jack (and perhaps the ace or king) and asks for attitude with an honor. The nine shows the ten (and maybe the ace, king, or queen) and asks for an attitude signal. The eight or lower is either fourth best (if that's your agreement) or high from a weak holding that might include a higher spot card.
Be aware that the standard exceptions to Rusinow apply here. Lead the top of touching honors in partner's suit, dummy's suit, or (after you have preempted) in a suit you did not bid. Against notrump slams you should also lead the top of touching honors (The K lead is not ambiguous -- it always shows KQ! - AW) Additionally, if partner made any lead directing double (eg. 1NT P 3NT X), the suit you lead is assumed to be partner's suit, so your lead is standard. Logically, if you lead a doubleton, you are leading partner's suit, and so lead high to unblock.
Note: From KQJx it will usually be best to lead the jack, showing the queen and asking for an attitude signal with the ace or ten. If dummy holds two small (for example) and partner encourages, you can continue with a low card, running the suit when partner started with Axx and declarer T9xx, or setting up the suit cleanly when partner started with Txx and declarer A98x. If partner discourages on your lead of the jack, you will continue with the king, and partner will give present count.
In summary, Ace from AKx(x), AKTx, AKJx
King from KQT9x, AKJTx, AKQTx
Queen from KQx, KQ9x, KQTx
Jack from QJx, QJ8x, QJ9x, QJTx, KQJx, AQJx
Ten from JTx, JT8x, JT9x, KJTx, AJTx
Nine from T9x, T98x, QT9x, KT9x, AT9x
High from doubleton honors
Opening leader should be aware of when it is superior to lead low from three honors, when there is an appreciable chance that an opponent has four cards in the suit. In particular, Larry Edwards was famous for recommending leading low from five or six cards containing AT9, KT9, or QT9, but not the eight. He was right more often than not.
Thanks to Linda Lewis, who agreed to play "strong king leads" and then suffered through the ambiguous queen lead from KQ and QJ before she suggested Rusinow for the lead of the queen or lower.
Special thanks to my wonderful wife Kelly for being so supportive of all my bridge activities.

N
Carding
V
1)
Signaling philosophy
*
a)
We move towards Grant Baze's rule: Never signal when it might help declarer. We don't go all the way, though. If a signal will likely help partner then we give it.
V
2)
Normally upside down attitude, standard count
V
a)
When we give count from four cards we play second highest, even if the two highest cards are touching
*
i)
e.g. 7 from 87xx or 9 from T9xx. But the highest from 6.
*
ii)
From an honor sequence highest is still best if hoping to win a trick, e.g., Q from QJTx.
*
b)
When we give attitude we normally encourage with our lowest card and discourage with the highest non-honor we can spare.
V
3)
Count echo vs. NT
V
a)
When following suit to the first suit declarer plays, third hand gives present count in the suit of the opening lead
*
i)
If third hand's count is known, or if it could not be relevant, he shows SP.
V
4)
Trump echo
*
a)
Normally we give count, unless the situation cries out for suit preference. In general, we try to give the signal that partner is most likely to need.
V
5)
Splitting
*
a)
In general we split with the lowest of touching honors. We may split highest from three touching honors if it looks as though it will be easy to read.
V
6)
Obvious Shift
V
a)
Obvious shift principle typically applies only versus suit contracts. We use a 'seat of the pants' approach, not the rules that the Granovetters recommend.
*
i)
It sometimes applies against NT -- we need examples here. TO DO.
V
7)
Returning partner's suit
*
a)
Usually we return our original fourth best. If it were clear that we had length, we might lead back a higher or lower card to make the (present) count clearer. If our length were not known, we might lead back our lowest to make sure that partner knew that we had at least four cards in the suit.
V
8)
When partners leads the K against a suit contract and dummy holds Qxx or longer:
*
a)
Attitude -- low only from a doubleton, or if we can't stand the obvious shift.
V
b)
Count against slams or if a doubleton is not possible.
*
i)
We do not treat the five level specially.
V
9)
Spot card leads during the hand
V
a)
Same as on opening lead except
*
i)
We will often choose to lead high from a suit of any length with no honor.
*
ii)
2nd highest through declarer when dummy’s suit is weak
