Red utilizes two advanced Soldiers flanking the Black palace to pivot into the central file, forming an instant Cannon mount to deliver a decisive checkmate.
This endgame puzzle exemplifies the devastating synergy between a Central Cannon on the 5th file and dual advanced Soldiers dominating the enemy palace. Although Black possesses threatening low Pawns poised to strike Red's King, Red retains the critical initiative and exploits Black's cramped, defenseless King position. By executing the classic screen-creation maneuver ('borrowing a mount'), Red locks all lateral escape squares and unleashes an unstoppable direct Cannon attack. The overarching tactical lesson highlights that endgame speed, precise screen generation, and restrictive geometry often triumph over raw material count.
