Stonewall Attack Puzzle (Rated 1428): Win with a Fork — Decisive Material Gain
This middlegame puzzle is all about tactical awareness when the king is exposed and a key defender is loose. Black can use a forcing check to pull the white king into a worse square, then win material by attacking the hanging bishop and overloading White’s defenses. The position rewards active piece coordination, especially when one piece is pinned and another is undefended. These are classic classical chess tactics: force the king, then collect material.
