3 Notes for Roche-Rayner CANADA 1. 1NT 12 to 14 except vulnerable in 3 rd and 4 th. UPGRADES AND DOWNGRADES ALWAYS PERMITTED Balanced or semi-balanced including singleton honours 2C or 2D Stayman doesn t promise a major 2D as a passed hand is a major suit scramble After any X DON T runouts; XX forces 2C After 2C (any meaning but both M s) X = Stayman and ST NT system on After 2C (Majors) X = Values; 2M = competitive with both minors; 2NT is one minor; 3 level minor is natural and forcing After 2D and higher negative X and Transfer Lebensohl 2. 1NT rd /4 th when vulnerable UPGRADES AND DOWNGRADES ALWAYS PERMITTED Stayman and 4 suit transfers, Smolen, Negative X s 1NT 2C 2H 2S is 4S INV After X - XX is relay to 2C for 1 minor, otherwise system on Other competitive situations as for weak NT 3. 1m 1M 2M structure - Weak NT situations a raise to 2M shows 4 trumps (99%) Next highest bid is a relay. Step responses show distribution and strength. In Strong NT situations a raise shows 3 or 4 card support. 2NT is artificial and inquires way GT after 1M 2M. Cheapest bid is a relay starting a short suit try. 1H 2H 2N = S as a long (help) suit try. 1M 2M 3M is a try in NT usually with a 6 card M 5. Drury (fit) 2C shows 3 card support. 2D reply to 2C is either sub-minimum or a hand that will make a game try as per note 4. Repeat of M shows a normal opener that would not accept a LR. Responder may bid again. 2D Drury (fit) shows 4 card support 6. Major suit raises in competition 2NT is always artificial Our lower Q bid is GF and higher Q = limit. If responder is a passed hand then lower Q is best possible hand and higher Q is a mixed raise 7. Transfers after overcalls. If next hand X P or bids 1NT, we use transfers starting at the Q bid of opener s suit. 8. Transfers after 1M X starting at 1N = C. Single raise weak. Transfer raise is constructive values or better.

4 9. Modified BART. After 1M P 1NT (forcing) - direct responses show stronger hands and slow step-like transfer bids indicate some sort of flaw, and are often artificial. 10. Polish 2H = H and another suit usually at least HCP (MAY UPGRADE OR DOWNGRADE) 2S = Pass or correct later 3S = to play 2NT asks and 3H = Majors 3C Pass or Correct 3D INV in Hearts 3H Non-forcing 3S = Invitational (Responder s own suit) Polish 2S = S and a minor usually at least HCP (MAY UPGRADE OR DOWNGRADE) 3C = P/C 3D = INV in Spades 3H = Invitational (Responder s own suit) POLISH INTERFERENCE 2H (2S) X = P/C 2N = H INV 3 of minor to play 2H (3C) X = P/C 3D to play 3S = INV 2H (3D) X = P/C 3H = competitive 3S = INV 2S (X) 2NT = S INV 2S (X) 3C = P/C 2S (X) 3D = own suit to play

5 11. MULTI INTERFERENCE We bid 2H (P/C) and they bid 3 of a minor We seldom (closer to never) bid in this situation We bid 2S (P/C) and they bid 3 of a minor X = H Pass = S 3H = H with Club tolerance We bid 2N (Values) and they bid 3 of a minor X = Min weak 2 in H, P = min weak 2 in S - Bid 3M with a maximum
