Queen Vs Two Bishops Puzzle (Rated 1237): Fork — Endgame Tactics

An endgame fork can overturn the material balance when one piece is overloaded, trapped, or exposed to a forcing check. In this position, White uses queen activity to exploit Black’s vulnerable king and the limited mobility of a bishop. The key idea is not simply to attack material, but to combine check with a second threat. This forces the defending king into an awkward square and leaves a valuable minor piece unable to escape.
