The most common checkmate involving a Horse and and a Cannon is what I call The Horseback Cannon checkmate . In this checkmate pattern, the Horse stands two points away from the opponent King on a rank or on a file. The Cannon checks the King from behind the Horse. Fig 1. If it is Red’s turn to move: C2=4 checkmate. If it is Black’s turn to move. H1-3 checkmate. The Horse acts as Interception Force while teaming up with the Cannon as the Assaulting Force. Fig 2 shows a special situation where the Horse gives checkmate (H7+6), while the Horse-Cannon Duo and the King jointly serve as the Interception Force.
On the right are two Horseback Cannon checkmate patterns frequently used in real games.
H2+3 K5+1, C2+6 mate.
H2+4 K5=6, C5=4 mate.
