Win 2: two cannons from hand mate on the back rank (Black)

56 moves

The shortest win here, 28 moves. Red is ahead for the first twelve moves, then a cannon dropped in the corner starts Black’s attack on Red’s back rank. Black ends it by giving up a soldier and a chariot from hand to pull Red’s pieces into place, then drops two cannons.

e5-e8: the cannon takes the advisor Black dropped on move 2. A captured defender goes into hand like any other piece.

R@d8: Red drops the chariot it won a move earlier. +2.0, Red’s best moment.

R@c1+: Black answers with a chariot on Red’s back rank, and the lead shrinks to +0.4.

C@a1: a cannon dropped in the corner, behind the chariot on c1.

c1-c3+: the chariot takes the horse and uncovers the cannon on a1, which checks through the horse on d1.

a1-i1: the cannon jumps over Red’s own general to take the chariot on i1.

f10-d8: an elephant takes the horse that checked on d8, and next move it takes the cannon on b10 too.

P@e1+: a soldier dropped on Red’s back rank. The general takes it.

R@d1+: a chariot given away to pull Red’s horse onto d1, where it will screen a cannon.

C@d1: the second cannon from hand becomes the screen for the first. The chariot on d9 guards it, and Red’s own pieces fill e2 and f1. Mate.
