Learn How to Spot Mate in 1: Triangle Mate
This puzzle is a classic example of a mating net in the middlegame, where king safety matters more than material. White’s heavy pieces are coordinated around the enemy king, and the key idea is that the king’s escape squares are already restricted by its own pieces and pawns. When a queen can invade the last rank or a weak g-file square, even a seemingly ordinary capture can become decisive because it creates immediate checkmate with no defense available.
