Polish Opening Sacrifice Intermediate Puzzle (Rated 1340): Spot a Discovered Attack — Mate in 2
This middlegame puzzle is a classic example of a discovered attack turning into a forced mating net. White’s pieces are coordinated around the enemy king, and one tactical jump opens lines for the queen to deliver the final blow. The key idea is that the first move is not about winning material immediately; it is about forcing a response that removes a defender and exposes the king. In tactical chess, that kind of tempo often decides the game.
