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