Zukertort Opening The Walrus Puzzle (Rated 1419): Fork — Decisive Material Gain
This middlegame puzzle comes from the Zukertort Opening and shows how a single active queen can create a decisive material gain. Black’s attack is built around a fork against loose pieces and an exposed king, with the white king still stuck in the center. The key idea is to use tactical pressure on undefended targets rather than chasing a direct checkmate. In classical chess, these positions often reward accuracy, forcing moves, and quick conversion of activity into material.
