Position and objective
Red material: Chariot + Horse. 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 d9. Trace Red's h6-d6 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red h6-d6 (車二平六), Black e8-d7 (士5进4), then Red d6-d7 (車六进一) 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 chariot shifts from h6 to d6. The black advisor moves from e8 to d7 in the recorded reply, and the chariot advances one point to d7 with mate. The advisor reply changes the target on the final file.
Do not skip the advisor’s e8-d7 move when replaying the position. It determines the occupancy around the palace before the chariot advances.
