Cochrane Gambit Puzzle (Rated 1503): Exploit an Advanced Pawn — Decisive Attack
This middlegame puzzle shows how an advanced pawn can become the spearhead of a winning attack. White’s pawn on the sixth rank cramps the black king’s shelter and creates tactical pressure on the kingside. The key idea is that the defender’s pieces are overloaded: one line of defense is tied to the king, while another piece is pinned or forced into a passive role. In positions like this, activity and forcing moves matter more than material count.
