Position and objective
Red material: Chariot + Soldier. 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 f7. Trace Red's f5-f6 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red f5-f6 (兵四进一), Black f7-e7 (將6平5), then Red f6-f7 (兵四进一) 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 soldier advances from f5 to f6. The recorded reply shifts the general from f7 to e7; the same soldier advances again from f6 to f7 for mate. Follow the soldier’s forward direction and the general’s changed file separately.
The general’s sideways reply does not mean the chariot must take over. Update its square, then test the same soldier’s second advance.
