{ There are other simple fortresses to know that involve bishops. In this case, white controls the queening square, but the h7 pawn (on the opposite color of the bishop) simply cannot be pushed aside. Here, black stays as close to the h7 pawn as possible, and draws easily. } 1. Kf6 Kf8 ( 1... Kh8 $4 2. Kf7# $1 { A rare situation where a single bishop is able to deliver checkmate! } ) 2. Kf5 Kg8 3.
