Learn How to Spot a Mate in 1: Bishop Checkmate
This middlegame puzzle is a pure tactical finish: White has a direct mating attack against the black king, and the position collapses immediately because the king’s escape squares are restricted. The key idea is to look for forcing moves first, especially checks that also coordinate with long-range pieces. In classical chess, these one-move finishes often come from a bishop or rook controlling critical diagonals and files, turning a seemingly normal position into a sudden checkmate.
