Queens Gambit Declined Tartakower Defense Puzzle (Rated 1081): Skewer — Crushing Middlegame Tactic
This puzzle is a classic middlegame example of a short skewer: a powerful queen check forces the king to move, and that creates a direct attack on a more valuable piece behind it. The key idea is that the defending queen is overloaded, so once the king steps aside, the loose rook becomes vulnerable. In practical classical chess, these tactical refutations often decide the game immediately because the opponent’s pieces are poorly coordinated and the king is exposed to a forcing sequence.
