BOSTON (Defense)


quiz-pic

When defending, you should shift to BOSTON (an acronym coined by famous bridge teacher/author Barbara Seagram) . That stands for "Bottom Of Something, Top Of Nothing." This is a way to tell your partner if you have interest in the suit you are shifting to. From, say, ♠872, you would lead the ♠8. (Note that this is opposite from standard signalling--where throwing/playing an 8 would say you like the suit and playing/throwing a 2 would show dislike).  From ♠K73, you would lead the ♠3. A low-card shift means you are leading from something. When partner sees a high-card shift, he will assume it is top--from nothing.
