Position and objective
Red material: Chariot + Horse. Black defenders: Elephant.
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 e9. Trace Red's b6-c8 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red b6-c8 (馬八进七), Black e9-d9 (將5平4), then Red i4-d4 (車一平六) 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 horse jumps from b6 to c8. The recorded reply moves the general from e9 to d9, after which the chariot shifts from i4 to d4 and mates along the d-file. The opening horse move and the long final chariot move have different path restrictions.
Inspect every intervening point on the chariot’s i4-d4 route. The horse’s ability to jump does not apply to the chariot.
