What is the "Stayman convention"?
The Stayman convention is a way for a player to ask their partner if they have four cards in either hearts or spades after the partner has bid no-trump. The player does this by bidding clubs, which signals the question. If the partner has four cards in one of these suits, they will respond by bidding that suit. The goal is to determine if the partnership can play in a major suit, which can often lead to a better result than playing in no-trump.
