Opening Puzzle (Rated 1275): Exploit — Overload

This King's Gambit middlegame demonstrates how an overloaded defender can collapse under tactical pressure.

The position also features a hanging piece and a discovered attack, showing how material advantage depends on coordination rather than simply counting pawns and pieces.
