Kings Gambit Declined Keene Defense Puzzle (Rated 1430): Crush with a Fork — Decisive Material Gain
This middlegame puzzle is all about a crushing fork that turns active piece play into a decisive material gain. White’s rook has created immediate tactical pressure, but Black can answer with a forcing sequence that exploits king exposure and loose coordination. The key idea is that a strong tactical move can be worth more than the attacked piece itself when it also creates a check and wins a major defender. In classical chess, these combinations often decide the game on the spot.
