Strong Square Puzzle (Rated 1797): Spot a Queen Sacrifice — Tactical Pin

This middlegame puzzle is built around a forcing queen sacrifice that drags the enemy king and defenders into a tactical net. The key idea is not raw material count, but the way one piece can be overloaded while another line becomes vulnerable to a discovered attack. The bishop pair and active rook coordination create pressure on the king zone, and the pinned pawn structure helps the attack keep momentum. Once the first forcing move lands, the position becomes a sequence of checks and captures that wins decisively.
