Woolsey convention

Devised by Kit Woolsey,[1] 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[2] can bid 2♣ to ask for the minor (pass or correct), 2♦ to ask for the major, or 2♥ or 2♠ to play.
2♣Promises 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.
2♦Promises one of the major suits.
2♥/2♠At least 5–5 in the named major and a minor.
2NT by Advancer asks for the minor.
2NTPromises both minors.
3 of any suitNatural.
This article describes the contract bridge bidding convention.

The convention has similarities with Multi-Landy.

Abuses

Common abuses as described by Kit Woolsey include:

  • 3-1-4-5 distributional hands in the balancing seat regularly double, even with no 4-card major suit.
  • Strong hands, with 19 high card points plus, start with a double and then rebid 2 Notrump (or double) to try to expose a psychic bid.
  • Good 4-4-4-1 distributional hands with a stiff minor suit can start with 2♣.
  • Single-suited minor hands often start with double, hoping to be able to play at the two-level. These hands will pass a 2♦ asking bid.
