Within contract bridge a stolen bid is a bid which usually lacks connection to the bidders own hand, and instead is used for blocking a certain bid (or a range of several bids) to be expressed from the next opponent.[1][2] To "steal a bid" is mainly done when the opponent to the right has given a conventional bid which the opponent to the left is likely to reply to. By far, most stolen bids are related to the Stayman convention. But also other conventions where some kind of reply is expected, the "reply range" can at least in theory be stolen. Blackwood is another example of a convention that might be exposed to a stolen bid.
