French Defense La Bourdonnais Variation Mate In 2 Puzzle (Rated 1131): Spot a Mate in 2 — Queenside Attack

This middlegame puzzle is a classic example of a forcing queenside attack that ends in a mate in 2. White’s pieces are coordinated to exploit the enemy king’s limited mobility, while the black king’s shelter is already weakened. The key idea is to use a forcing check that drags the king into a worse square, where the final mating move becomes unavoidable. In positions like this, activity and coordination matter more than material.
