If a cue-bid is doubled: pass by partner shows weakness or waiting bid, redouble = first control, continue cue-bidding shows support for the doubled cue-bid (Queen or singleton) and return to trump suit = sign-off with no support for the doubled cue-bid. If partner pass over the doubled cue-bid: redouble = first control, continue cue-bidding shows KQ or singleton, return to trump suit = Rx(+). - In the sequence 1M-(3X): 4 = ART and shows good hand with support without control in opponent suit, 4 = ART and shows good hand with support and with control in opponent suit. - When 4NT is not RKC? - Over a NT bidding by partner (exceptions when there is a clear trump established) - When there is no clear fit established (Ex.: 1-2 -3-4NT) 2

Ex.: 1 -(1 )-2 /2 by passed hand = 3/4 card support - New suit at 2-level = F1, may be weaker than 2/1 free bid b) Double of a minor opening bid - 1/1 = system on - 2-level bids = NF - jump-shift = fit showing - 2NT = limit raise or better - Redouble = 10+ HCP and forcing till 2NT or DBL the opponents c) Double of a major opening bid - 1 over 1 (DBL) = NAT with 5+ - 1NT or above until raise = transfers - 2 over 1 (DBL) and 2 over 1 (DBL) = good raise - 2-raise = weak - 2NT = limit raise or better with 4 trumps 3

g) Doubled Stayman - Pass = no stopper in (RDBL by responder = Stayman,others = NAT) - RDBL = 2 stoppers (responder 2NT = INV with or without major, 3 = Stayman GF) - Respond to Stayman = 1 stopper Note 9: Check-back Stayman 1m 1M 1NT? - 2 = forces to 2 to show INV hands or signoff - 2 = ART GF - 2NT = forces 3 to show 55 GF hands or signoff Note 10: Special 4 th suit sequences a) Reverse sequences -4 th suit at 2-level = ART minimum hand (5-7) b) 1m 1 1? c) 1 1 2? Examples: 1 1 1 1 2 2 2 2-4 th suit at 3-level = ART and GF - 2 = forces to 2 to show INV hands or signoff - 2 = ART GF - 2NT = forces 3 to show 55 GF hands or signoff - 2 = forces 2 to show GF hands or signoff - Others = INV Note 11: Defense against 3NT Gambling - DBL = Penalty - 4 = 5M + 5m - 4 = 5 + 5-4 = Natural - 4 = Natural Note 12: Defence against 2 /2 : Weak 5M + 5m - DBL = TO of that M or 20+ BAL - 2NT = 16-19 (Transfers, 3S=STAY if 2S, 3D=STAY if 2H) - 3NT = tricks - CUE = stopper ask - others = NAT - 4m = 5m/5OM, FG - 4OM = NAT 5
