1S-pass - 2S pass ?
- 2NT = asks in which suit responder would accept a help suit game try. Reponses:
- 3C = accept clubs. If opener now bids 3x it is a help suit in that suit.
- 3D = reject clubs, accept diamonds
- 3H = reject minors, accept hearts
- 3S = reject any help suit try
- 3NT = natural, choice of games
- 4S = game raise, no slam interest
- 3D = reject clubs, accept diamonds
- 3C,3D,2H = short suit game tries
- 3S = choice of
- a) power try
- b) trump try
- c) show 123 stop
- b) trump try
- 3NT = offering choice of games (i.e., trump support with balanced hand)
- 4C,4D,4H = long-suit slam tries, promising a 5-card side suit and a good hand
- 3C = accept clubs. If opener now bids 3x it is a help suit in that suit.
Over 1H-pass-2H-pass, same applies, only 2S is the ask, and 1 notrump bid shows spades, and 2NT is a short suit try in spades. 3 S is natural, 5-6 slam try.
After short suit tries, a repeat of the short suit try is a void suit slam try. A different suit beyond 3M is a cue bid and shows a short suit slam try with a singleton.
After 2NT, opener's new suits above 3M show a help-suit slam try (probably in an accepted suit) and are cue bids.
