Woolsey convention

This article describes the contract bridge bidding convention.

Devised by Kit Woolsey, the convention is a defense against an opponent's one notrump opening; especially used at matchpoints. Initial bids are as follows:

Initial CallMeaning
DoublePromises a four-card major and a longer minor.
Advancer can bid 2 to ask for the minor (pass or correct), 2 to ask for the major, or 2 or 2 to play.
2Promises both majors.
Advancer can bid 2 to ask which is better, so the overcaller's 2 bid can freely be made with 5-4 shape.
2Promises one of the major suits.
2/2At least 5–5 in the named major and a minor.
2NT by Advancer asks for the minor.
2NTPromises both minors.
3 of any suitNatural.

The convention has similarities to Multi-Landy.
