Queens Gambit Accepted Alekhine Defense Puzzle (Rated 1322): Win a Hanging Piece — Decisive Advantage
This middlegame puzzle is a classic example of exploiting a hanging piece while the enemy king remains stuck in the center. White’s active knight jumps into the position with tempo, forcing Black to respond to a direct tactical threat rather than improving development. The key idea is simple: when a loose piece is attacked and the king is exposed, material gains often come with check or a forcing sequence. In classical chess, these tactical refutations frequently decide the game immediately.
