Pin Puzzle (Rated 1238): Spot Skewers — Win Material
A skewer attacks a valuable piece while exposing another target behind it. In this middlegame, Black must calculate the relationship between the queen, bishop, and White’s active rooks. The key idea is to exploit an overloaded defender and the pressure created by a pin on the f-pawn. Strong tactical play often comes from combining a forcing attack with a positional gain, especially when an enemy piece is attacked by a lower-value unit.
