Queens Gambit Accepted Rosenthal Variation Puzzle (Rated 1233): Skewer — Decisive Material Gain
This middlegame puzzle is a classic example of using a forcing tactical sequence to win material. White’s active bishops and queen coordinate against a vulnerable black king and loose back-rank pieces, creating a position where one tactical shot opens the way for a major gain. The key idea is that a check can force the king onto a square where the queen then attacks along a line, exposing a valuable piece behind it. The result is a clean conversion of activity into material.
