:''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. Bids are as follows: * Double: 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: 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: One major. * 2 of a major: At least 5-5 in that major and a minor. 2NT asks for the minor. * 2NT: both minors. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Woolsey convention」の詳細全文を読む スポンサード リンク
