Learn How to Spot Mate in 1: Slav Defense Puzzle
This middlegame puzzle comes from the Slav Defense and shows how a seemingly active position can hide a forced mate in 1. The key idea is king safety: when the enemy king is boxed in and your queen has access to a critical square, tactical threats can override material concerns. Even in classical chess, the best move is often the one that ends the game immediately rather than winning more material.
