One soldier hunts the general into the corner
153 moves
MistyBanqi has the first seat and turned up the black pieces; the player has red. From move 44 a single red soldier hunts its general into the a1 corner and leaves it with no legal move. The general is lost on move 86, and MistyBanqi wins anyway on move 153.
MistyBanqi has the black pieces. Its general is on b1, and the red soldier that will hunt it is on b4.
The soldier holds a1. The general on b1 can’t move onto the face-down tiles on c1 and b2, and a general can’t capture a soldier, so it has no legal move. It stays stuck until move 85, when it takes a red advisor flipped up on b2, and the red general captures it on move 86.
The red general takes MistyBanqi’s general on b2.
The player has no piece left to move, so MistyBanqi wins.
