Woolsey Defense to 1NT Openings woolsey后续叫牌

for strong NT: Double = usually a 5-card minor and a 4-card major
for weak 1nt (11-15): double= Penalty : point>=max like 13/14/15, respond bid like 1nt open, sys on.

2C: = majors, respond bid 2D: asks for preference
2D: = one of the majors
2H: = H: and a minor
2S: = S: and a minor
2N = both minors
3X = natural

• Responses to Double: for strong NT open

2C: = Asking minor, 加被人是梅花可以pass, 否则叫2D
2D: = what's your major? (NB: NOT forcing)
2H,2S: = natural, to play
2NT = artificial, please describe minor,邀叫实力

3C: = min clubs
3D: = min diamonds
3H: = max clubs
3S: = max diamonds

3C:,3D: = to play
3H:,3S: = natural, invitational, good suits
3NT = to play
4x = Namyats

If they interfere after double:

2NT = pick your minor
all else natural (no way to find major)
double suggests defending

• Responses to 2C:

2D: = you pick a major
2M = significant preference; xxx KQ bids 2D:
2NT = artificial game try

3C: = min, hearts better then spade
3D: min, spade better then heart
3H: Max, heart better
3S: Max, Spade better

3C: = natural preemptive
3D: = natural preemptive
3M = natural blocking, not invitational, 5-card suit
3N = to play
4x = Namyats

If they interfere after 2c:

Everything is natural, including double

• Responses to 2D:

2H: = normal
2S: = heart fit, forcing to 3H:
2NT = artificial game try

3C: = min, hearts, etc.
3D: min, spade suit
3H: Max, Heart
3S: Max, Spade
after 2NT, 4M by responder is to play

3C:,3D: = to play
3H: = pass or correct, blocking
3S: = pass or correct
3N = to play
4x = Namyats
If they interfere after 2d:

2NT = bid your major
double = penalties
All else natural

• Responses to 2M:

2S: = to play
2NT = artificial game try, see below

3C: = min, clubs
3D: = min, diamonds
3H: = max, clubs
3S: = max, diamonds
3N = max, unwilling to play a partscore and hold appropriate minor such that 3M is not forcing

3C: = pass or correct
3D: = to play
3M = natural, blocking
3OM = natural, preemptive
3N = to play
4x = Namyats
If they interfere after 2M (including double):

2NT = bid your minor
3C: = natural
All else natural

If they double an artificial bid, unsolicited bids are interest in playing the suit bid. Pass is to play the artificial suit; redouble is no opinion.

Woolsey争叫被对方干扰后的叫牌规则: 如果不确定争叫套，用2nt问叫； If no long suit is sure, 2NT asks. All else natural.

Over 2M, 2NT is an artificial game try and 3C: asks for correction to diamonds if appropriate.

Responses to 2NT:
3C: = min, clubs
3D: = min, diamonds
3H: = max, clubs
3S: = max, diamonds
3N = max, unwilling to play a partscore and hold appropriate minor such that 3M is not forcing.

We play the 2NT ask after:

Woolsey 2M
Hamilton 2M
Woolsey double if comp
Michaels cue-bids of a major

Common abuses: 变异用法：

3145 hands in balancing seat regularly double, even with no four-card major.
Very big hands (good 19+) start with double and rebid 2NT (or double) to try to expose a psych.
Good 4441 hands with a stiff minor can start with 2C
Single-suited minor hands often start with double, hoping to be able to play at the 2-level. These hands will pass a 2D ask.
注意： 单套牌需要好的六张或者超好的五张
(1NT)-2D， 单套高花
(1NT)-2D-（P）-2S: 争叫人搭档的2S表明我至少有3-4张红心，能承受在三阶打红心定约，搭档你要是黑桃，你可以pass, 你要是红桃好牌你可以进局。
