2-way New Minor Forcing Improvement to New Minor Forcing Writeup at La Jolla Bridge Club website
Two-way Reverse Drury Similar to Reverse Drury, but now over 3rd/4th seat major-suit opener 2 or 2 asks if it's a full opener. 2 promises 4+ card support w/ 10+ hcp. 2 same with exactly 3-card support. Opener then responds:
2 of their suitLight opener
Anything elseFull 13+ opener
Responder continues as needed. Notes:
1. if responder holds long club suit they bid 2, then 3 over any bid by opener.
2. Drury is OFF over any interference.
Four-way transfers Special handling with minor-suit transfers (1N-2, 1N-2N)
If opener has Hxx or better in the transferred suit, bid the "in-between" suit. Responder can bid 3N if appropriate. Otherwise, bid the transfer suit.
Four-way transfers with "range ask" Special handling for club transfer (1N-2). Transferor now can have EITHER 6+ clubs, OR the standard invitational 8-9hcp balanced without 4-card major.
Opener shows whether or not they'd accept a balanced invite:
2N Have minimum 1N; would not accept a balanced invite. Transferor either passes or corrects to 3
3 Maximum 1N.

Transferor rebid after opener bids 3:
3, 3, 3 1st round control, slam interest.
3N Good club suit. Enough values to expect game.
4 Gerber.
"8 over 8" Responding to 1N opener, holding 8hcp and 8 cards 8 or higher, invite with 2N. Otherwise, PASS.

Also applies when holding flat 14hcp. Consider opening 1N with 8 cards 8 or higher.

Bergen Raises With 4-card support for a major, expands beyond Jacoby 2N:
3 Constructive
3 Limit
3 of other major Ambiguous splinter
3 of major Pre-emptive
Checkback club Improvement over New Minor Forcing Writeup
Fitting jump shiftJump-shift response by passed hand (OR in competition!) shows that suit (must be a source of tricks) plus at least a 3-card limit-raise in opener's suit.
Fourth suit forcing Bidding 4th suit - game-forcing, asks partner to describe hand (in priority order):
  • Raise partner's suit with 3 cards
  • Bid NT if 4th suit stopped
  • Raise 4th suit with 4 cards
  • Make most natural bid otherwise
EXCEPTION: 1 in this sequence: 1-1-1-1 is NOT forcing.
Help-suit game try When opener's 1-of-major opening is raised to 2, bidding another suit is the help-suit game try. It asks partner if he can "help" in that suit. Maybe you have a half-stopper, or Axxx, or whatever. It's a mechanism like splinters, for finding games (or even slams) with less than the normal 26 (or 32) HCP.
This could be used over a limit raise, if you are slamming?
Impossible Spade After this sequence, 1 - 1N (forcing) - 2 or 2
2 limit raise of the minor; with either 5+ clubs or 4+ diamonds. Responder can't have a Spade suit as they would have bid that instead of 1N.
3 or 3 8-9hcp raise or minor.
2 or 2N If neither of the above bids is correct, choose the appropriate one of these
Major openings partial writeup of 1 of major responses

Raising with 3-card support (article by Dave Vidaver)
Mini-Roman 2 Shows 11-15HCP, and 4-4-4-1 distribution. Or 4-4-5-0, as long as 5-card suit is not a major. Make sure to have 14-15 HCP if opening with Spade shortness. Responses:
Weak hand (<10HCP) Bid fragments up the line. Strive to find lowest level 4-3 or better fit.
Forcing hand Bid 2N, asking for shortness. Take from there.
Minor openings Minor opening / major response scenarios
Minor opening / non-major response scenarios
Inverted minor raise shows 4-cd support, opening hand, denies 4-cd major. [With Scott, I play it this way]
Criss-cross (jump-shift into other minor shows limit-raise)
"Muppet" Stayman Tweak of Puppet Stayman: swap meaning of 3 and 3N:
3: opener has no 4-card majors
3N: opener has 5-card Heart suit
Now responder has room to show their own 5-4 major suit distribution by bidding 3
New Minor Forcing INCOMPLETE Used after 1m - 1M - 1N sequence. Opener has limited their hand to 12-15hcp. Responder bids other minor to inquire about support for their major.
Openers responds (in priority order):
2M3-card support for major. Less than maximum hand.
3M3-card support for major. Maximum hand.
2If major was , shows 4-card heart suit.
2NBalanced minimum.
3NBalanced maximum.
Rebid own minor at cheapest levelDefault. Long minor only. Missing stoppers in other minor.
Reverse Bergen With 4-card support for a major, expands beyond Jacoby 2N:
3 10-11 HCP; limit raise
3 7-9 HCP; weak hand
3 of opener's major 0-7 HCP; pre-emptive
Reverse Bergen (1st/2nd seat open only) With 4-card support for a major, expands beyond Jacoby 2N:
3 10-11 HCP; limit raise
3 7-9 HCP; weak hand
3 of opener's major 0-7 HCP; pre-emptive
Bergen is OFF if responder is a passed hand. 3 becomes weak jump shift; 3 is 8-9hcp with 4-cd support. Reasoning: with 4-card support, responder should use Drury.
Reverse Drury Over 3rd/4th seat major-suit opener, 2 asks if it's a full opener. Promises 3+ card support w/ 10+ hcp. Opener then responds
2Full 13+ opener
2suitLight opener
2Special case if Spade opener -- shows good opener w/ 4-cd Heart suit.
Responder continues as needed. Notes:
1. if responder holds long club suit they bid 2, then 3 over any bid by opener.
2. Drury is OFF over any interference.
Rule of 15 In 4th seat, open any hand where high card points plus the number of Spades is 15 or higher. Concept is that a weaker hand would have more Spades -- and can find a partial there.
Rule of 20 / (Rule of 22) When evaluating a borderline opening hand, add the number of cards in the two longest suits to the high card points. If that is 20 or higher, go ahead and open. Note: Jerry Helms recommends that you additionally have 2 quick tricks.
Rule of 9 Helps to decide when to make a penalty double, or how to proceed after partner makes a takeout or re-opening double. In either case, first add up:
  • Level of the contract
  • Number of cards in opponent's suit
  • Number of honors in opponent's suit (including 10s)
NOTE: Devalue honor holdings such as KQ, KJ, KQJ, QJ, QJT by 1
Double for penalty, if count is 9 (with extras). Always double with 10 or more.
In a competitive auction, when partner has doubled, if above sum is 9 or more, PASS. Otherwise, either bid your best suit, or raise your partner with a minimum of two card in their suit.

Exceptions:

  1. If count comes to 8 AND you have at least 2 unexpected tricks, you may pass -- converting the double to penalty.
  2. If opponents open in a game bid, it is often correct to pass even your count is less than 9

Checkback 2N (aka Spiral) Responder inquires about strength of support in 1m-1M-2M sequence. See Minor opening / major response scenarios
Wolff Relay Used after 1m - 1M - 2N sequence to show weak hand, less than game-going values.
PASS, 3N, or 4M -- are signoffs.
Any other bid except for 3 is game forcing. Possible bids:
3Relay to 3, then:
Same majorPass or correct (staying on 3 level!)
3After 1 shows weak 5-5 in majors. Opener passes or corrects to 3
3Unknown -- needs discussion!!
3N Slam interest in opener's minor
3Similar to New Minor Forcing:
3OM4 cards in other major. Responder can bid 3N or 4M accordingly
3M3-card support. Responder bids accordingly.
3N Neither of the above.
3M5+ cards, extras, slam interest
3After 1, shows 5-5 or better in majors, forcing
3After 1, Unknown -- needs discussion!!

PREEMPTIVE BIDS AND RESPONSES

Feature ask (over weak 2s) Basic method for responder to find out strength of partner's weak 2 bid. With good hand, opener bids a "feature" -- usually a short suit, or suit with an honor. With a lousy hand, opener rebids their suit.
Gambling 3NLong, running minor with outside Ace. Writeup at bridgehands.com
Namyats Allows pre-empting opener to differentiate between a strong, distributional opener that may have slam potential -- and weaker pre-emptive suits.
3 Standard 7-card heart pre-empt
3 Standard 7-card spade pre-empt
4 Strong 8-card heart suit
4 Strong 8-card spade suit
4 Weak 8-card heart suit
4 Weak 8-card spade suit

Responses to the "strong" pre-empt:
In-between suit Have slam interest. Opener then uses Blackwood, control-bids, or just bids the slam.
4 of major No slam interest
Ogust (over weak 2s) popular alternative to "feature ask" response -
Evaluate suit quality based on partnership agreement! Weak hand is generally lower half of weak-2 point range.

Preempt hand evaluation Opener:
  • count "playing" tricks:
    • Every card after 3rd in trump
    • Aces, supported Kings (Kx), covered Queens (AQx, KQx)
  • Then bid count +2 Vul, or +3 NotVul -- but don't go above a "game" bid in that suit
Responder: subtract 2 (Vul) or 3 (NotVul), then
  • Add quick tricks:
    • A, K, or Q of trump = 1 trick each
    • In other suits: AK=2, AQ=1.5, KQ=1, A=1, Kx=0.5
    • Singleton, with trump support = 1 trick
    • Void, with trump support = 2 trick
  • And bid or pass accordingly. Example: Vul, opener has 7 playing tricks -- opens 3; responder has 5 quick tricks -- bids 6
Preemptive Gerber When partner preempts 2X or 3X, 4 is Preemptive Gerber (4 if partner bid ), and you have slam interest (Full writeup by Sara Rothmuller & Harvey Brody).
Key cards are A or K of trump, or outside Ace. Preemptor can't have all 3!

Rule of 17 Responding to partner's weak-2, add the number of trump cards you hold to your HCP. If the total is less than 17, there is no game. Otherwise, you can explore for game.

Step Rebids (over weak 2s) responses to 2N force over weak 2 Summary (Original writeup by Ronnie McMurdie)
Weak 2s 6-card suit, usually a major. 5-10hcp normal range. Standard treatment - vulnerable should have 2 of top 3 honors. Experts disagree...

SLAM BIDDING

1430 Gerber 4 over NT opening asks for Aces 4=1 or 4; 4=0/3; 4=2.
Now, there is always room for asker to bail at 4N.
Then, 5 asks for Kings.
Asking Bids With a known major-suit fit, a non-jump to the 5 level (bypassing 4N) asks for first- or second-round controls in that suit. Bid:
5 of agreed suitno controls in asked suit
6 of agreed suitsecond round control of asked suit
cuebid of asked suitfirst round control of asked suit
Note that you can only ask about suits lower than the agreed suit.
DOPI/ROPIHandle interference over Ace-asking bids:
DOPI over suit interference: (think D0P1) DBL=0, PASS=1, then up the line otherwise
ROPI over DBL interference: (think R0P1) RDBL=0, PASS=1, then up the line otherwise
Exclusion Blackwood With a known fit, a jump to the 5-level in another suit is RKC1430 excluding the Ace in the suit bid.
Gerber 4 over NT opening asks for Aces 4=0 or 4; 4=1; 4=2; 4N=3.
Then, 5 asks for Kings.
Over response to 4, 4 means "bail out at 4N". See 1430 Gerber below if you want to avoid problems when the response is 4N and you can't bail.
Grand Slam ForceWith a known fit, a jump bid of 5N inquires about partner's top three trump honors. With 2 or more trump controls, responder makes a Grand Slam call in the trump suit. Otherwise, the responder signs off in a Small Slam.
Kickback If "slamming" suit is Hearts, 4 is RKC1430 ask:
4N1 or 4
50 or 3
52 or 5, no queen
52 or 5, have queen
Now asker always has room to bail at 5. Further bids are same as RKCB.

NOTES:
  1. Not alertable during auction as it can "wake up" partner. Must be disclosed before opening lead.
  2. Because 4 is Kickback, 4N is a Spade cuebid.

McCabe [Taken from this article by Robert Todd.]
When partner opens a 2-level preempt and RHO makes a takeout double, we know that the auction is about to become competitive. Most of the times that we want to compete in the bidding in this kind of auction are when we have a fit for partner's suit. Since this is the case, then it makes sense to assign more than one bid to promise a fit for preemptor's suit -- to allow us more than one way to show a fit for partner's suit.

Over Weak-2 - (DBL):

2 (over 2)Raise to 3, with values in -- asking for lead

Over a major, shows other major & unspecified minor. 2N asks for minor.
Over a minor, shows BOTH majors.
Normally, hand is weak or strong. With intermediate hand, make an overcall instead.

Advancer makes minimum response with weak hand, otherwise jumps or cuebids.

Meckstroth Advances - complex response to Michaels overcall [Taken from this article by Robert Todd.]
When the opponents open the bidding with a Major suit at the 1-level and partner makes a Michaels cuebid, showing 5+ cards in the other major and a 5+ card minor suit, then Advancer has only a small amount of space to describe their hand and figure out the best place to play. Most partnerships use a 2N by Advancer to ask the Michaels bidder to bid their minor suit, while some partnerships use 3 to accomplish the same thing with the Michaels bidder passing or correcting to 3. Meckstroth Advances are a system of bids for Advancer that allow us to describe a large variety of hands in these highly competitive auctions.
Advancer must have better than opening to employ any of the invitational bids as partner could be very weak.

Assuming auction as gone (1M) - 2M - P - ?, Advancer bids as follows:
2Weak 2+ card support for Spades, less than invitational values.
2N*Game try with fit for both minor suits. Invitational+ values.
3Pass or correct.
3*Invitational with 3+ card fit for OM
3 Over 2 bid (OM is ), this is game forcing Western Cuebid. Usually no major suit fit.
Over 2 bid (OM is ), this to play, weak 2+ card support for Hearts.
3 Over 2 bid (OM is ), this is shapely invite, 4+card , fewer values.
Over 2 bid (OM is ), this is game forcing Western Cuebid. Usually no major suit fit.
3NTo play
4Pass or correct. Large fit, 4+cards, for both minors. Less than invitational values.
4*Game Forcing OM raise. 3+ card OM. Forcing Passes On!
4 * Over 2 bid (OM is ), Splinter in support of .
Over 2 bid (OM is ), to play, shapely hand. Not a lot of values.
4 Over 2 bid only. To play, shapely hand. Not a lot of values.
4NGame Forcing raise to 5-minor. Asks opener to bid minor. Strong hand.
5Pass or correct. Large fit, 4+cards, for both minors. Pre-emptive, not a lot of values.
Suction Over strong artificial club openings (Standard American 2; Precision 1) -- shows either single- or two-suited hand.
2 shows Hearts or Spades/Clubs
2 shows Spades or Clubs/Diamonds
2 shows Clubs or Diamonds/Hearts
2N shows either Clubs/Hearts or Diamonds/Spades

Easy memory aid: whatever suit you bid, is the one you CAN'T have.

Advancer bids the single suit; if two-suited, overcaller corrects to lower suit; advancer can correct to other suit.
Unusual NT Jump to 2N over 1-lvl bid 4N over pre-empt. Shows 5-5 in 2 lowest unbid suits; most of hcp should be in these suits.
We also play "Unusual 1N" when bid over opponents' 1-over-1 auaction. Eg. 1 - P - 1 - 1N shows 5-5 in the black suits.

HANDLING BIDDING INTERFERENCE

Four-suit transfers
(used when opponents
double 1N for penalties)
RDBL is transfer to 2, 2=2, 2=2, 2=2
Handle lead-directing doubles of
1N responses (e.g., transfers or Stayman)
When opponents double a transfer (or Stayman) bid, it's usually lead-directing. Use RDBL to mean "I want to play here." Thus, the sequence 1N - P - 2 - DBL - RDBL means "I want to play 2 redoubled!"
1N Response Bid (by 1N opener) after lead-directing double
Transfer, e.g., 2 RDBL="to play"; 2="I have 3+ spades"; PASS="fewer than 3 spades, don't like hearts"
Stayman, e.g., 2 RDBL="to play"; 2="No 4-card major"; 2|2="I have 4-card major"; PASS="No 4-card major, don't like clubs"
Transferor then bids appropriately:
  • Leaves redouble in with support.
  • Bids the transfer suit (2 over 2**) -- drop bid.
  • Bids transfer again at 3 level -- please accept the transfer!
Interference over 2 Control responses are OFF; DBL == bust; PASS == have something; any other bid shows slam interest.
Jordan2N following takeout double of partner's opener, shows good support with 10+ hcp.
Lebensohl Used in 3 different scenarios:
  1. handling 1NT interference,
  2. response to takeout double over weak-2 opening by opponents, and
  3. response to opener's reverse

    1) Over 1NT interference:

    Initiated by responder after partner has opened 1NT and right hand opponent (RHO) has overcalled with two in a suit.
    Off over 2 interference, except if artificial showing specific suits (e.g., Landy showing majors).

    Opener Overcaller Responder
    Response Meaning and Subsequent Bidding
    1NT 2, 2, or 2 2 in a higher ranking suit natural and non-forcing
    2NT a puppet bid forcing the opener to bid 3; after that:
    • 3 in suit of lower rank than overcalled: natural, to play
    • 3 in suit of higher rank than overcalled: natural, invitational
    • 3 in the overcalled suit: Stayman, asking partner to bid a 4-card major suit and showing a stopper in the overcalled suit
    • 3NT: to play, showing a stopper
    3 in any suit except that overcalled natural, forcing to game
    3 in the overcalled suit Stayman, asking the partner to bid a 4-card major suit and denying a stopper in the overcalled suit
    3NT to play, denying a stopper
    Over artificial interference (e.g., Cappelletti, DONT):
    1. Both suits known: cheaper cuebid is invitational, higher is forcing. All Lebensohl rules are on.
    2. One suit known: known suit is cuebid.
    3. No known suit: you can't use cuebid.
    4. Cuebid is Stayman-like unless overcall shows both majors (e.g., Cappelletti 2)
    5. Delayed cuebids deny stopper
    6. 4-level jumps retain original meaning
    7. Delayed DBL (after PASS) is penalty.
    8. Delayed suit bid is competitive.
    9. Vs. artificial doubles (e.g., DONT): IGNORE IT! 2 is Stayman, etc.
    10. Vs. penalty doubles, use four-suit transfers (RDBL is , 2 is , etc.)

    2) Response to takeout double over opponent's weak 2 bid

    (eg., 2 - DBL - P - ?):
    • With weak hand (0 to bad 7 hcp), bid 2N which relays to 3. Doubler either passes or corrects.
    • With intermediate hand (good 7 to 11 hcp), bid directly at 3 level.
    • NOTE: when holding 4 or 5 cards in a major ABOVE the weak-2 suit:
      • With 4-card major, relay through 2N, then cue-bid.
      • With 5-card major, relay then bid the suit.
    • With game values, bid the game.
    If there is room at 2-level, for example over 2, 2 is weak. Relay to 3 is now intermediate with 5-card suit. Direct to 3 would be game forcing.
    NOTE: with strong hand, opener can bypass 3 relay and bid appropriately.

    3) Responding to opener's 2-level reverse

    With 2-level reverse, opener shows 16+ hcp. Using Lebensohl, responder with weak hand (5-7 hcp) can stop short of game. With better hand, responder can now make game-forcing bid.
    3a) Responding to opener's reverse to 2
    (eg., 1 - P - 1 - P - 2 - P - ?):
    • With weak hand, bid 2N. Opener relays to 3. Responder either passes or corrects. Opener should then drop.
    • Any other bid is game forcing.
    With a strong hand, opener can and will bid more than 3.
    3b) Responding to opener's reverse to 2
    (eg., 1 - P - 1 - P - 2 - P - ?):
    • With weak hand, bid 4th suit which relays to 3. Responder either passes or corrects. Opener should then drop.
    • Any other bid including 2N is game forcing.
    Again, with a strong hand, opener can and will bid more than 3.
Maximal double After 1M-2M sequence, over inteference where normal invites are not available, DBL shows game invite. Partner bids 3M or 4M depending. Can leave double in, with stack in their suit.
Examples: 1 - (2) - 2 - (3) - DBL; 1 - (2) - 2 - (3) - DBL
Also used when we are overcalling & opponents bid & raise in a lower suit:
Example: (1) - 1 - (3) - DBL (3 would be merely competitive);
Negative Double Over 1 of minor and opponent's 1-level overcall, DBL promises:
1 - (1) - DBL 6+ hcp, and 4+ cards in BOTH majors
1m - (1) - DBL 6+ hcp, and either 1) 4 spades, or 2) weaker with 5+ spades
1m - (1) - DBL 10+ hcp, and either 1) 4 hearts, or 2) weaker with 5+ hearts
1 - (2) - DBL 8+ hcp, and 4+ cards in at least 1 major
1M - (2m) - DBL 8+ hcp, and 4+ cards in other major
1 - (2) - DBL 10+ hcp, and 4+ cards in BOTH minors
Responsive double Response to a takeout double or overcall, when opponents have bid & raised their suit.
1M - X - 2M - X is responsive double, scattered values, 4 cards in the other major and no long suits (because you would bid a 5-cd suit if you had it!).
When you double over partner's overcall (e.g., 1H - 1S - 2H - X), you should also be able to tolerate partner bidding their suit again (IOW, have 2+ cards in that suit.)
6-8 hcp at 2-level; 9+ hcp at 3-level
NOTE: if opponents have bid & raised a minor, the responsive double promises 4-4 in the majors.
Rule of 2 1 0 When deciding to bid 5 over 5 in a competitive auction:
  • With 2 of their suit, X for penalty
  • With 1 of their suit, pass
  • With no cards in their suit, bid 5
Support double / redoubleOver interference following 1x - any - 1M - any, double shows 3-cd support. Ex: 1 - P - 1 - 2 - DBL shows 3-cd spade support.
Support redouble used over takeout-double interference. Ex: 1 - P - 1 - DBL - RDBL shows 3-cd heart support.
We play no upper limit on this type of double. NOTE: many players set the limit at 2 or 2
Transfer Lebensohl Similar principle as Lebensohl, except there are only 2 hand strengths to consider: weak or invitational+. Writeup at Larry Cohen's website
Unusual vs. Unusual (method 1)Mechanism for handling Michaels or Unusual NT interference (most common version I play):
Cue bid higher suit10+ hcp with a fit (iow, limit raise or better)
Cue bid lower suit, IF KNOWN10+ hcp, no fit
Raise our suitCompetitive with support
New suit (or new minor if 2nd suit not known)Invitational with 5cd suit
DoubleValues in one of opps. suit & ability to penalize opps. in one or both suits.
Pass Several possible hands:
  • Good defensive hand, but not sure if we can set them.
  • Lousy hand.
  • No other bid makes sense.
Unusual vs. Unusual (method 2)Mechanism for handling Michaels or Unusual NT interference (aka, lower-lower higher-higher):
The unusual bid usually shows 2 suits. Cue bids indicate one of the other 2 suits.
Cue bid lower suit10+ hcp with a fit in the lower of two other suits
Cue bid upper suit, IF KNOWN10+ hcp, fit in higher of two other suits
Raise our suitCompetitive with support
New suit (or new minor if 2nd suit not known)Invitational with 5cd suit
DoubleValues in one of opps. suit & ability to penalize opps. in one or both suits.
Pass Several possible hands:
  • Good defensive hand, but not sure if we can set them.
  • Lousy hand.
  • No other bid makes sense.

DEFENSIVE CARDING

A is for Attitude, K is for Count Against 5-level contracts or higher:
  • Ace is led. Partner shows attitude -- high suggests continue leading same suit
  • King is led. Partner shows count -- high implies even number.
Ace is led, singleton on board Against suit contracts, show suit preference.
Lavinthal discards First discard against NT is suit you don't want led. Size of spot indicates suit preference. Preserves suit length in your good suit.
Not recommended against suit contracts as you often want to discard in a short suit to increase ruffing chances.
Leading doubleton Ace-King Against suit contract, lead King from Ace-King to show doubleton.
"Obvious" shift Writeup by Dave Vidaver here.
Discuss with partner which signal -- "obvious shift" or "singleton on board" applies when there is singleton or void on the board.
"Obvious" shift --- bill Writeup by Dave Vidaver here.
Obvious shift is OFF is there is a singleton or void on the board.
Odd-even attitude discards When giving attitude, even card discourages, odd card encourages.
Trump suit echo, Smith echo Writeup
Upside-down attitude (standard count) When giving attitude only, reverse the standard convention. I.e., attitude: high card discourages, low card encourages.
For count, use the standard echo: high-low means even count.
Upside-down count & attitude When giving count or attitude, reverse the standard convention. I.e., attitude: high card discourages, low card encourages; count: low-high means even count.
