Zukertort Opening Lisitsyn Gambit Deferred Puzzle (Rated 1417): Win Material — Discovered Attack

This puzzle shows a classic middlegame tactical refutation where a discovered attack creates immediate pressure on the enemy king and queen. White’s active bishops and knight coordinate to force a response, and the key idea is that one capture opens a line for another piece to attack with tempo. In positions like this, the strongest move is often not a direct threat but a forcing move that reveals a hidden attack while winning material and disrupting coordination.
