Rat Defense Harmonist Intermediate Puzzle (Rated 1351): Fork — Crushing Opening Tactic

This opening puzzle shows how a forcing queen move can create a crushing fork against an exposed king and an active bishop. In the opening, king safety matters more than material, and even a small development lead can become decisive when the opponent’s king is stuck in the center. The key idea is to use check to gain tempo, restrict the king’s options, and win a loose piece with a tactical sequence.
