Three Knights Opening Winawer Defense Puzzle (Rated 878): Win Material — Discovered Attack
This middlegame puzzle shows a classic tactical refutation where an active queen and bishop create a direct threat against the enemy king and queen. The key idea is discovered attack: one piece moves with tempo, opening a line for another piece to strike a more valuable target. In positions like this, king safety matters more than material count, because an exposed king can force a winning sequence that also wins the opponent’s queen or other major piece.
