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 Call | Meaning |
|---|---|
| Double | Promises 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. |
| 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. |
| 2NT | Promises both minors. |
| 3 of any suit | Natural. |
The convention has similarities to Multi-Landy.
