Kangaroo Defense Keres Defense Puzzle (Rated 813): Crush with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that wins material by forcing the king and a loose piece into the same tactical net. Black’s active queen creates immediate pressure against the white king, while White’s pieces are awkwardly placed and several pawns are weak or isolated. In positions like this, the key is to look for forcing moves that combine check with a direct attack on an undefended target.
