Learn How to Win Material: Tactical Refutation
This chess endgame puzzle is all about a tactical refutation that turns a skewer into a winning material sequence. White’s active rook looks dangerous because it attacks along the c-file and seems to pressure the black rook and knight at once. But the position contains a hidden defender-capture idea: once the key piece is removed, the follow-up simplifies into a favorable endgame for Black. The lesson is that active rooks can be punished when they overextend into a defended tactical net.
