Grob Opening Spike Attack Puzzle (Rated 1376): Win Material — Hanging Piece

This middlegame puzzle is a classic example of how king safety can outweigh raw material. White’s queen is already active near the enemy king, and Black’s back rank and loose pieces create a tactical target. The key idea is to notice the undefended rook and the exposed king at the same time. In classical chess, these positions often reward forcing moves that win material first and keep the attack alive.
