"Standard" Precision is a strong-club system with natural positive responses to 1C. With our version of Transfer Precision, we bid a strain other than what we have in order to have the stronger (and less defined) hand as declarer more often. Here's a quick rundown on our responses to the forcing 1C opening:
1C (16+HCP if unbalanced, 17+ if balanced; any shape)
- 1D = 0-7 HCP or 8+ with a 4441 shape (any singleton)
- 1H = 8+ HCP, 5+ spades
- 1S = 8+ HCP, 5+ hearts
- 1NT = 8+ HCP, 5+ clubs
- 2C = 8+ HCP, 5+ diamonds
- 2D = 8-13 HCP, balanced
- 2H, 2S, 3C, 3D = 4-6 HCP, six-card suit
Over partner's transfer positive, opener can bid the suit shown to show a fit and start a (short - for now) series of asking bids. Here's an example of our asks at work:
1C - 2C;
2D - 3H;
3S - 4C;
4N - 5H;
7D - P.
1C = 16+, artificial
2C = 5+ diamonds, 8+ HCP (game force)
2D = Tell me more!
3H (sixth step)= Six-card suit with one of the top three honors
3S = Tell me more!
4D (third step)= Three controls outside diamonds (A=2, K=1; this must be the ace of clubs and king of spades)
4NT = Keycard ask in diamonds (eventually we'll use 4H for this, but we haven't gotten around to discussing all the ramifications of this yet); opener doesn't yet know if responder's suit is Axxxxx or Qxxxxx
5H = Two keycards without the queen of diamonds
7D = Six diamonds plus AK of the other three suits is twelve tricks... if partner has club length I can get a club ruff for the 13th. With my club shortness it makes it more likely that he has length there. Well, here goes -- I hope he has 3+ clubs or a major-suit queen!
How would you and your partner get to this 29 HCP grand slam?
