Learn How to Spot a Mate in 1: French Defense Tactic
This puzzle comes from a French Defense middlegame where king safety is the deciding factor. Even though material is roughly balanced, the position is tactically lost because the exposed king and active queen create an immediate mating net. In classical chess, these patterns often appear after one side’s pieces coordinate on open lines and the opponent’s king lacks flight squares. The key lesson is to always check for forcing moves before evaluating anything else.
