Ruy Lopez Steinitz Defense Beginner Puzzle (Rated 927): Win a Fork — Decisive Material Gain

This Ruy Lopez puzzle shows a classic opening tactic where a knight jump creates a crushing fork against the enemy king-side coordination. The key idea is not just winning a piece, but exploiting loose back-rank-style development and an exposed queen-rook setup. In the opening, tactics often work because one side has not finished development and important pieces are tied to defense. When a fork hits multiple valuable targets at once, the resulting material gain can be decisive.
