Queens Gambit Accepted Rosenthal Variation Puzzle (Rated 855): Crush a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that wins material by forcing the king into a bad square and then exploiting a trapped piece. The key idea is that one checking move can do two jobs at once: it restricts the king and creates a direct threat against a valuable target. In positions like this, tactical accuracy matters more than long-term strategy, because the side to move can convert activity into a decisive material advantage immediately.
