Position and objective
Red material: Double Chariot. Black defenders: Advisor.
Mate the black general within the move limit. Red moves first and the AI answers for Black, with every move validated as it is played.
The black general starts on f9. Trace Red's c6-c9 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red c6-c9 (車七进三), Black f9-f8 (將6进1), then Red g5-g8 (車三进三) mates. This is one legal continuation of the validated solution.
The shortest mate takes two moves. The complete move list is on this page — try to find it yourself first.
The first move is the key to the forced mate. Black may have other legal replies; the line below shows one verified continuation.
Key move and common mistakes
The left chariot advances from c6 to c9 and checks. After the general advances from f9 to f8, the other chariot advances from g5 to g8 for mate. One chariot changes the general’s position and the other supplies the finish.
Identify which chariot makes each move. The second chariot must attack the general on its updated rank rather than continue the first chariot’s route.
