Position and objective
Red material: Horse + Soldier. Black defenders: Advisor + 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 d7. Trace Red's c6-c7 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red c6-c7 (兵七进一), Black d7-d8 (將4退1), after the intervening moves Red b3-c5 (馬八进七) mates. This is one legal continuation of the validated solution.
The shortest mate takes three 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.
