The positions show that red is losing, but 'che', the program finds a rook sacrifice to take checkmate quickly.

The red general may not take the rook because black has a cannon behind the king's pawn. The advisor captures the rook. If the general moves then the other rook will deliver checkmate by moving along the rank.
