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 ; in other words, a bishop is unable to guard squares of the other color. 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. ==Rook versus bishop== White wins in this position. The defender has the wrong bishop if it is on the same color as the corner where his king is confined. Black's bishop is on the wrong color of square for it to form a fortress in the corner (i.e. with the black king on the h8-square and the bishop on the g8- or h7-square). White wins: :1. Kf5! Kg8 :2. Ra4!! The only way to win. If 2.Kg6? Kf8 and the black king is able to get out of the "dangerous corner" or "wrong corner" and head to a "safe corner" or "right corner" where he can set up the fortress. :2... Be1 :3. Kg6 Kf8 :4. Rf4+!, followed by 5. Re4, winning . 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「Wrong bishop」の詳細全文を読む スポンサード リンク
