After interference 1D - (X) - XX = 12hcp+, F2NT or penalties. 1H/S = Natural, forcing. 1NT = Natural. 2C/D = Natural with 5+ suit, non-forcing. Jump = Preemptive. 1D - (1M) - P = Forcing pass. X = Negative. The double of 1H denies 4spades. 1S = Natural 4+, forcing. 1NT = Natural. 2X = Natural 5+, forcing. 2M = GF without major. The opening 1H/S The openings 1H/S will almost always contain an unbalanced hand. The opening 1H may contain exact 4-4-1-4. The only balanced hand is 12-13hcp and 5332. The hcp range for the opening is 9-16. The transfer sequences are mainly taken from Magic Diamond. After 1H: 1S = Natural, forcing 1NT = Transfer to 2C 2C = Transfer to 2D 2D = Exact 3 card support with at least invitational values. 2H = 3-4 card support, not invitational values. 2S = Invitational values with 4+support and a singleton minor. 2NT = Stenberg, GF with 4+support. 3C = 8-13hcp with 4+support. 3D = Invitational values with 4+support and singleton spade. 3H = Preemptive with 4+support. 3S = Void, slam invitational. 3NT = To play (normally with 4-3-3-3 distr). 4m = Void, slam invitational. 4H = To play 4S = To play After 1S: 1NT = Transfer to 2C 2C = Transfer to 2D 2D = Transfer to 2H. 5+ suit if hearts :) 2H = Exact 3 card support with at least invitational values. 2S = 3-4 card support, not invitational values. 2NT = Stenberg, GF with 4+support. 3C = Invitational values with 4+support and a singleton minor. 3D = 8-13hcp with 4+support. 3H = Invitational values with 4+support and singleton heart. 3S = Preemptive with 4+support. 3NT = To play (normally with 4-3-3-3 distr). 4m = Void, slam invitational. 4H = Void, slam invitational. 4S = To play After 1H - 1S, 1NT a kind of Checkback Stayman is used: 1H - 1S 1NT - 2C (Checkback) 2D = 12-13NT with 3-5-2-3 2H = 12-13NT with 3-5-3-2 2S = 12-13NT with 2-5-3-3 With a minimum unbalanced hand you normally want to support responders 1S with only 3 card suit (with 5332 always rebid 1NT as shown above). Responder then may search further for exact distribution: 1H - 1S 2S - 2NT = Distributional search (remember that opener has a minimum hand). 3C = 3-5-1-4 3D = 3-5-4-1 3H = 3-6-(x-x) with bad hearts and Hxx in spades. 3S = 4-5-(3-1) -> 3NT asks for singleton suit. 3NT = 4-4-1-4 4C = 4-5-4-0 or 3-6-4-0 4D = 4-5-0-4 or 3-6-0-4 4H = 4-5-2-2 1H - 1S 2NT = 14-16hcp, 4 card support. 3S = 11-13hcp, 4 card support with 5-6 losers. Transfer responses and continuation 1NT and 2m are transfers to the next suit with either a weak hand and a long suit or at least a constructive hand and a 4+card suit. Note 1! No particular strength is needed for the transfer responses. The objective can be to mess with the opponents, suggest a lead, invite a sacrifice, or, of course, start a constructive bidding sequence. Partner assumes typically HHxxx(x) in the shown suit even though that is no requirement. Note 2! Transfer to a minor over 1S may be strong with 4H and 4333 distr. With support, openerís actions depend a little on whether the transfer was to a minor or to hearts. The raises are described below. After any rebid by opener, responderís simple raises are invitational. Opener accepts the transfer Opener accepts the transfer if he would have passed a natural non-forcing bid based on a long suit. Responderís rebid in openerís major shows exactly 2-card support and 5-card shown suit, or (2-3)-4-4 and 8-11hcp (respond 1NT to 1M). Responder is just trying to find the best part-score with a constructive hand. Responderís new suits at the two-level are natural and forcing to 2NT. Opener does not accept the transfer Rebid of the opening suit is just a suggestion to a better trump suit with a good 6-card suit. 2D over 1M-1NT is natural with a good 5-card suit. Neither of these two bids show or deny extra values. 2H over 1S - 1NT/2C is natural and denies minimum, i.e. 5S+5H, 6S+4H, or good 5S+4H. 2S over 1H - 1NT/2C is natural and shows a very good hand. Support after 1M-1NT/2C * 2NT shows a max (hcp) hand with 3+ support. 3m shows a good hand with 4+ support. * 3M shows typically 7M+3m and maximum. * 4m shows 5+card support and 10+ cards in the two suits. * Jumps in new suits show shortness, usually with 5+card support. 1M - 1NT/2C 2NT - 3M = Hx in openers major. Support after 1S-2D 1S - 2D 2H = Accept of the transfer. 2S = Own good suit. 2NT = 3card support (or exact 5-4-2-2), fairly balanced with maximum. 3m = Natural, normally 5-5+ and some values. 3H = 3card support (or exact 5-4-2-2), normal hand. 3S = 7+ spades and (2)3 card support. 3NT = 4card support and a singleton minor. 4m = Void, 4card support. 4H = I want to play 4H opposite HHxxxx in hearts and out. Normally 4card support. Over 3NT, responderís 4C asks for the shortness => 4D=diamonds and 4H=clubs. Trump support 1H - 2D 2H = Minimum. 2S = Romex, demands 2NT on which a singleton is shown (3H = singleton spade) 2NT = Romex, at least 3card spades 3m = 3+ 3H = To play 3S/4m = Void 1H - 2D 2H - 2NT = Balanced GF, 4333 or 4432 distr. 3C/D = Natural with 5 card+. 1S - 2H follows the same structure with Romex to show either long or short suit and some strength. After 1M - 2M Romex is also used if opener have a sensational hand. 1M - 2M, 3M is preemptive. After 1H-2S and 1S-3C opener may relay to find responders singleton. 1 step shows singleton club, while 2 steps show singleton diamond. After 1H-3C and 1S-3D opener may also relay to ask for min/max. With maximum responder jumps to 4M or cue-bid if good hand, with minimum he bids 3M. After interference When the opponents compete we use free bids in new suits and negative doubles, according to the following schemes: * Takeout Double After a takeout double by the opponents all our systemic agreements are still on, i.e. transfers and so on. * Redouble Shows 12hcp+ and expresses a wish to double for penalties. This means that doubles of all following non-jump bids by the opponents are for penalties. If third hand passes, opener may make a direct call with a distributional minimum hand that will not accept a penalty double. * Overcall Responderís bid in a new suit on the 2-level is non-forcing, to look for a fit for constructive or sacrificing purposes, or maybe just lead-directing. * Negative Double Doubles of overcalls are negative up to and including 3S. Such a double by responder asks the opener to show his longest suit, i.e. rebid a 5+ major rather than a shorter minor. OM rebids are natural, but 2S after 1H-(2m)-D does not promise five hearts, since 4-4-1-4 is possible. Jump rebids also follow these principles, but with better hands. No-trump rebids are used with otherwise unbiddable hands, such as 4441 distributions, or the 5332 distribution with 12-13hcp.. Responderís new suits are forcing. * Trump Support after overcall Jump raises are pre-emptive and single raises are just normal and 2NT is still GF. A cue-bid below 3M is invitational. * Overcalls/Doubles after Transfer responses Double shows a good hand with no clear-cut alternatives. Redouble shows a good hand with 3-card support. Note! If opponentsí double shows the suit, a cuebid is splinter with a good hand with 3-card support and a good 6-card opening suit. After responderís single raises (1M-2M and 1H-2D/1S-2H) and an overcall, openerís double is a strong re-raise, except for 1H-2D/H-(2S); D, which may be takeout with a three-suited hand and only four hearts. 1 NT Balanced hand with 14-16hcp. Any preferred NT-structure could be used, i.e: 1NT - 2C = Stayman. 2D/H = Transfer to H/S. 2S = MinorStayman. 2NT = Invitational without major. 3C/D = Invitational with 6+ suit. 3H/S = Singleton, no 5c other major. 3NT = To play. 4C/D = Transfer to H/S. 4H/S = Natural After 1NT - 2C, 2D/H/S, 3C is a relay searching for distribution. 1NT - 2C 2D - 2H = Weak with both major. 2S = Inv. with 5S+4H 2NT = Nat., inv. 3C = Distributional search. 3D = 5 card diamonds and a 4 card major, GF. 3H = 5 card clubs and a 4 card major, GF. 3S = 5 card + 4 card heart, GF. 3NT = To play. 1NT - 2D 2H - 2S = Natural with 5-4, at least inv. 1NT - 2D/H 2NT = max with 4 card support, 4-3-3-3. 3X = Doubleton with 4+ support and max. 1NT - 2S 2NT = Best diamond or alike minors. 3C = Best club. 1NT - 2S 2NT/3C -P/3C/D = To play. 3H = (At least) GF with 3-1-(5-4) 3S = (At least) GF with 1-3-(5-4) 3NT = Both minor, 2-2-(4-5). 4C = 2-1-5-5 4D = 1-2-5-5 4H = Exclusion Blackwood with 3-0-5-5/2-0-(6-5) 4S = Exclusion Blackwood with 0-3-5-5/0-2-(6-5) Nilsland is used if 1NT - (X). After an overcall, negative doubles and Lebensohl is used. The opening 2C The opening 2C shows 9-16hcp and 5+ clubs. If 5C+4D then 14-16hcp. Balanced hands are opened in 1C, 1D, or 1NT. 2C - 2D = Relay, at least invitational. 2H/S = Not forcing, 5+ card. 2NT = Relay to 3C. 3C = Strong invitation. 3D = 5+, Game force(GF). 3H/S = 6+, GF. 3NT = To play. 4C = To play. 4D/H/S = Void, club support. 4NT = RCKB with club support. 5C = To play. The subsequent bidding : 2C - 2D 2H/S = 9-13hcp, 4 card suit. 2NT = 14-16hcp, unbalanced. 3C = 9-13hcp, unbalanced. 3D/H/S = 14-16hcp, 4(+) card suit, GF. 2C - 2D 2H/S - 2S = 5 card, forcing one round. 2NT = Balanced, invitational. Normally other major. 3C = To play. 3D = Relay, asks for outside stoppers. 3H = (after 2C - 2D, 2S) 5 card, GF. 3H/S = Invitational, 4 card support. 3NT = To play. 4C = Balanced slamint. with club support. 2C - 2D 2NT - 3C = Not forcing. 3D = Relay, asks for outside stoppers. 3H/S = 5 card, GF. 3NT = To play. 4C = Balanced slamint. with club support. 2C - 2D 3C - 3D = Relay, asks for outside stoppers. 3H/S = 5 card, GF. 3NT = To play. 4C = Balanced slamint. with club support. 2C - 2H/S Pass = Minimum. Normally doubleton support. 2NT = Maximum with doubleton support. 3C = Single/void i partners majorsuit. 3D = Maximum, huge minor hand. 3H/S = Maximum with 3+ support. 2C - 2NT 3C - Pass = To play, preemtive style. 3D = 6+, invitational. 3H = Both major(5-5)+, GF. 3S = Spades+Diamonds(5-5)+, GF. 3NT = Hearts+Diamonds(5-5)+, GF. 4D/H/S = singleton, slamint. with club support. After interference Negative doubles and forcing pass is used if an overcall is made on the 2-level After a take-out double the systemic agreements are still on. The opening 2D - 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. When vulnerable the opening should also contain a 4card+ minor suit. RESPONSES TO 2 DIAMOND OPENING: Pass = I have diamond and a short major suit. 2H = Not game if weak 2H. 2S = Natural, NF. 2NT = Minor suit search. To play at the 3 level, or 6+card major suit and GF. 3C = Artificial forcing bid.

REBIDS AFTER 2D - 3C 3D = Weak 2 in hearts -> 3H:Invitational. 3H = Weak 2 in spades -> 3S:Invitational. RESPONSES TO 2D - (Dobl) Pass = I want to play in diamond. RD = Bid your weak 2 suit. 2H = To play. 2S = To play. Other responses are as without interference. RESPONSES TO 2D - (D) - Pass - (Pass) Pass = 3+ diamonds. RD = 5-3 or 5-4 in the major suits. 2H = 5 heart & 4/5 clubs. 2S = 5 spades & 4/5 clubs. RESPONSES TO 2D - (2H/2S) Dobl = Request partner to pass with weak 2 in the overcalled suit. Other responses are as without interference. In 3.hand partner have at most 9hcp, so the range is 3-14hcp. The opening 2H/S The opening shows a 6 card suit and 3-8hcp. 2H/S - 2NT = Asking bid. 2S/3new = Natural, not forcing. 3H/S = Preemptive. 2H/S - 2NT 3new = singleton. 3H/S = 6-3-2-2, minimum. 3NT = 6-3-2-2, maximum. 3S/4new = Void.

Opener answer as after 2H/S - 3C The opening 2NT The opening 2NT shows 20-21hcp and do not contain 5 card major or a good 5 card minor. Further bidding may i.e. use a modified version of Cotter: 2NT - 3C = Transfer to 3D. 3D = 'Stayman' or own onesuiter (5+) in minor and slamint. 3H = 5 card +, GF. Opener should bid 3S with a 4 card suit. 3S = 5 card +, GF. 3NT = To play. 4C/D = Transfer to 4H/S. 2NT - 3C 3D - 3H = Slaminv. with both minors.
