Ruy Lopez Steinitz Defense Kingside Attack Intermediate Puzzle (Rated 820): Mate in 2 — Kingside Attack
This puzzle is a classic middlegame finishing pattern where the attack on the enemy king matters more than material. White’s queen and bishop coordinate to create a direct mating net around the black king, with the key idea being to force the king into a square where escape is impossible. The position shows how active pieces, king safety, and forcing checks can outweigh a material deficit in classical chess.
