The black general starts on e8. Trace Red's e6-e7 move on the diagram before checking Black's reply.
How the mate works
Verified line: Red e6-e7 (兵五进一), Black e8-d8 (將5平4), after the intervening moves Red a6-a9 (車九进三) 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.
