Fork Puzzle (Rated 1553): Win with a Fork — Middlegame Tactics
This puzzle is a classic middlegame tactic where activity matters more than raw material. White’s pieces are coordinated around the enemy king and loose rook, creating a forcing sequence that wins material while keeping the initiative. The key idea is to use check to drag the king into a worse square, then exploit the resulting alignment and hanging piece. In classical chess, these short tactical shots often decide the game immediately.
