Dutch Defense Janzen Korchnoi Gambit Puzzle (Rated 1396): Crush a Trapped Piece — Decisive Material Gain
This middlegame puzzle is a classic example of exploiting a trapped piece and a vulnerable king. White’s queen is active near the enemy king, but Black can turn the tables by creating a forcing sequence that wins material and leaves White’s attack unfinished. The key idea is to use a pawn break to open lines, then follow with a forcing queen maneuver that exposes the overextended white queen. In classical chess, these tactical transitions often decide the game before any endgame begins.
