Learn How to Spot Mate in 1: French Defense Tactic
This middlegame puzzle comes from the French Defense, Winawer Variation, and it shows how quickly a kingside attack can end the game when the enemy king is boxed in. White’s position looks materially better, but the king’s shelter is fragile and the dark-square control around the king is badly compromised. In classical chess, these are the moments where a forcing tactical refutation can override material and end the game immediately.
