The wrong bishop is a situation in chess endgame when a bishop on the other color of square of the chessboard would either win a game instead of draw or salvage a draw from an inferior position (Rosen 2003:61). This most commonly occurs with a bishop and one of its rook pawns but it also occurs with a rook versus a bishop, a rook and one rook pawn versus a bishop, and possibly with a rook and one bishop pawn versus a bishop.
