Remember that 1H/S can also be the strong hand. * Bid 1NT over 1 major. * Pass over 1NT response. * Pass or bid 3NT over 2NT/3C/3D. 1.1.2 MAXI OPENER * Natural over 1D. * Anything except single raise of 1H/S or 1NT over 1 major. * Natural over 1NT as pass shows the weak hand (except 2C which is 'Stayman'). * Something else except single raise or 2H/S. * Something else other than Pass/3NT over 3C/D and P/single raise of 3H/S. 1.2 SUBSEQUENT AUCTION 1C - 1D 1NT = 17-19NT. 2NT = 22-24NT. Puppet Stayman. 3NT = Gambling with a long suit. 1H/S = Either 8-11 hcp with 3-4 card suit or 17+ hcp with 4+ cards. 2C/D = Rebid of 2C/D is always the strong hand, natural without majors, since the strong hand always rebids 1H/S rather then 2C/D. 2H/S = Gameforce with at least 4 card. May contain longer minor suit. 3C/D = Natural gameforce, 5+card. Denies 4+ major. 3NT = 25 hcp+, NT-distribution without 4 card major. 1C - 1D 1H/S - 1S = 0-7hcp with 4+ cards, forcing for one round to the strong hand. 1NT = 5-7hcp without support or 5-card suit. 2X = 5-7hcp with 5+ cards, forcing for 1 round to the strong hand. 2H/S = 3-7hcp with 4+ support, forcing to the strong hand. Opener reraises with a minimum strong hand. The relay is Rosencranz, and a new suit positive trial bid (2NT for spades). 2NT = General GF without majors, balanced 23+ or 5422 with both minors. 3C/D = Natural GF with one suited hand. 3H/S = Game forcing splinter (also jump "raise") with both minors. 3NT = 20-22 balanced hcp, no majors. With the weak hand opener always passes in the third round unless responder forces. With the strong hand he bids naturally. Simple no-trump bids showing minimum for the strong hand, i.e. about 17-19 for 1NT. New suit is forcing after 2 over 1. Raises to 3C/D may be passed, lacking 3-card support to openers major. Other major after 1C-1D, 2min-2maj indicates some interest in responders suit, whilst a jump to 3NT denies that. After the single reverses, 4 of a new suit are also splinters. 1.3 The 1NT rebid The 1NT rebid shows 17-19hcp, and a simple NT-system is used. 1C - 1D 1NT - 2C = Stayman. 2D/H = Transfer (Jacoby). 2S = Transfer to minorsuit. 2NT/3X = Natural, invitational. 4C/D = Transfers to H/S. 1C - 1D 1NT - 2C 2D/H/S- 3C = distribution search. 1C - 1D 1NT - 2S 2NT = 3-3 or 4-4 in minor, or longer diamonds than clubs. 3C = Longer club than diamonds. 1.4 2 H/S rebid Game forcing with at least one four card major and possibly a longer minor, but rather not 4-6 except in hearts/diamonds. Beta asking bid can be used instead of this model. 1C - 1D 2H/S - 2S = 0-7hcp, 4+ cards. 2NT = 0-7hcp, unsuitable for another bid balanced/weak. 3X = 4-7hcp, reasonable 5+ cards. 3H/S = 4-7hcp, 4 card support, no shortages. 3NT = 5-7hcp, doubl. major, not 4 cards in the o/major, no 5-card suit, i.e.(3-2)-4-4 Jump = 4-7hcp, shortage with 4 plus support. 4H/S = 0-4hcp, 4 plus support. 1.5 2NT rebid Showing 22-24NT, and Puppet Stayman is used in the subsequent bidding. 1.6 3C/D rebid Natural GF, 3X=5card suit, 3NT shows 5-7 high card points without any suit interest, and 4X=cue with 3+support 1.7 Double jump to 3H/S or 4C/D Semi-solid/solid suit asking for number of controls (Ace = 2 controls, King = 1 control). 1 step = 0 controls 2 step = 1 controls 3 step = 2 controls, and so on.. 1.8 The positive response of 1H/S to 1C 1.8.1 MINI-OPENER After 1S/NT : 1C - 1H/S 1S/NT - 1NT = Signoff to 8-11. 2C = Artificial force.

Other bids are GF. Jump from 2H/S to 4 of a new suit are cue-bids. * After openers single raise the Rosencranz technique applies to invite with shortness. New suit is natural F (2NT with spades), frequently canapé in the minors. Reraise is preemtive. The Rosencranz technique announces some shortage and responder may relay in turn to be informed. Other bids are natural (see under the opening 1H/S). 1.8.2 MAXI-OPENER 1C - 1H/S 1S = 8-11hcp with 4/5 cards, or 17+hcp with exactly 5 spades. 2C = Artificial force.

Other = Natural GF. 1C - 3NT Pass = 8-11hcp. Other = Natural GF. 1.9 Disturbed bidding. 1C - (X) - ? Pass = Help yourself. XX = 12 hcp+, looking for penalties. 1X = Natural with some strength. Jump = Preemptive. 1C - (1X) - ? Pass = Nothing to declare. X = 10 hcp+, take out/negative. 1Y = Signoff, 5 card+. 2new = Mildly invitational. 1C - (2X) - ? Follow a natural line as after 1NT - (2X) - ?, e.g. 2NT = Lebensohl The following Lebensohl structure is used : * Direct cuebid is GF and shows 4 card in o/major, not control in opponents suit. * 3NT shows 4 card in other major and control in opponents suit. * 2NT followed by cuebid is GF, and denies both major and control in opps. suit. * 2NT followed by 3NT denies major but guarantees control in opponents suit.

MULTI This convention is a variation of Woodgroves Multi, but without the strong hands. The frequency is high since you quite often have a 5 card major-suit with 3-8 hcp. It's really fun to see your opponents trying to guess what you have when they are strong. RESPONSES TO 2 DIAMOND OPENING: Pass = I have diamond and a short major suit. 2H = Not game if weak 2H. 2S = Invitational if weak 2H. 2NT = Lebensohl.
