Rook And Pawn Vs Two Bishops Puzzle (Rated 1321): Pin — Rook Skewer

This chess endgame demonstrates how a pin can transform a material disadvantage into a decisive tactical advantage. A pinned piece may appear well placed, but its connection to the king can make it immobile. By placing a rook on the correct file, Black attacks the bishop while exploiting the king behind it. The result is a skewer: the more valuable target is protected only superficially, allowing the rook to win material after the king responds.
