Learn How to Win with a Long Skewer: Endgame Tactic
This chess endgame puzzle shows how a seemingly active rook and bishop can become vulnerable to a forcing sequence. The key idea is a long skewer: the attacker uses check to drive the king onto a line where a more valuable piece is exposed behind it. In practical classical chess, these patterns often appear when kings are centralized and rooks are active on open files. Even if you are materially ahead, one tactical shot can flip the evaluation immediately.
