Red leverages an advanced Pawn and controlling Rook to restrict Black's Cannon and break down the Full Defense system.
In this standard endgame of Rook and Pawn against Cannon with Full Advisors and Elephants, Red holds a strong positional advantage with a high Pawn on the 7th rank and a dominant 8th-rank Rook. By precise Rook maneuvers, Red systematically disrupts the connection between Black's Cannon and defenders, forcing Black's King into restricted squares. The key tactical lesson emphasizes using high-pawn pressure alongside active Rook placement to breach an otherwise complete defensive formation.
