Queens Gambit Accepted Mannheim Variation Puzzle (Rated 1494): Win Material — Intermezzo Tactics
This middlegame puzzle is a classic example of an intermezzo tactic: instead of taking the obvious recapture immediately, White uses a forcing check to improve the position first. The key idea is that Black’s queen is overextended and the king is vulnerable to tempo-gaining moves. When a high-value piece is loose and the opponent’s coordination is shaky, a forcing move can turn a simple material win into a decisive advantage.
