M := major
m := minor
x := ! M
Opening in majors in 1st or 2nd place, opponents make a direct X, meaning it's a takeout double.
Sequence | Meaning |
---|---|
1M - (X) - XX | No fit and 10+ tpts |
1M - (X) - 2NT | Fit (3 cards support) and 10+ tpts |
1♥ - (X) - 1♠ | 6-9 tpts |
1M - (X) - 2M | Fit (3 cards support) and 6-9 tpts |
1M - (X) - 2m | No fit, 6-9 tpts, and 5 in minor (alertable) |
1M - (X) - 1NT | 6-9 tpts and balanced hand and no fit |
The 4th player (Take-out Doubler's Partner) is forced to bid. Opener will either Pass or Double if he holds 4 cards in Opponent's suit. If the 4th player's bid is passed around, the Redoubler must take action, usually by either a Penalty double or a NT bid. (reference: http://www.jazclass.aust.com/bridge/br28.htm#03)
- 3M : Minimum hand (13-15 pts)
- 4M : Showing extras (16-21 pts)
- 3x : Help suit game try (2 or more losers in the suit)
- 4x : Forcing to game (0-1 cards in this suit, 16-21 pts)
- If partner opens 1♣/1♦ and then opponent double, the meaning of bid by responder is as the following (with priorities):
- XX = 6+ pts, 4+ in both majors;
- 1 ♠/♥ = 6+ pts, 4+ ♠/♥;
- With a 5 card support and 11+ tpts, make a jump in the other minor (Xriss-Xross bid)
- With a 5 card support and 6-10 tpts, say 2m.
- With a 5 card support and 5 or less tpts, jump to 3m.
- 1NT = 6-10 tpts without majors and no fit.
- 2NT = 11-12 tpts without majors and no fit.
- 3NT = 13-19 tpts without majors and no fit.
- Opener opens major in 3rd or 4th position, see Drury.
