Learn How to Skewer: Decisive Material Gain
This chess endgame puzzle is a classic long skewer idea: the queen creates a forcing check that drags the king onto a vulnerable square, then keeps the attack alive to win major material. The key is that the enemy back rank and loose heavy piece are aligned, so the checking sequence is not just about activity — it is about forcing the king to step aside and exposing the target behind it. In classical chess, this kind of tactical refutation often decides the game immediately.
