Position and objective
Red material: Chariot + Soldier. 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 f9. Trace Red's g3-g9 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red g3-g9 (車三进六), Black f9-f8 (將6进1), after the intervening moves Red g9-f9 (車三平四) 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.
Key move and common mistakes
The chariot checks from g9, and the recorded reply brings the general from f9 to f8. The soldier advances from f6 to f7 with check. After the general captures that soldier on f7, the chariot shifts from g9 to f9 and mates along the f-file. The soldier is sacrificed to draw the general forward.
Playing f6-f7 first does not check the general on f9. Start by changing the general’s position with the chariot. Remove the captured soldier before inspecting the final open file.
