▲6二と △同 玉 ▲8二飛 △同 金 ▲7四桂 △7一玉 ▲8二角成 △6一玉 ▲6二金

Why this move works

The answer is ▲6二と △同玉 ▲8二飛 △同金 ▲7四桂 △7一玉 ▲8二角成 △6一玉 ▲6二金. Sacrifice the tokin and rook to deflect the defending gold, set up with a knight, then mate with a gold — a nine-move tsume.

▲6二と △同玉 pulls the king to 6二, ▲8二飛 △同金 lifts the gold away, ▲7四桂 drives the king to 7一, and after ▲8二角成, ▲6二金 mates — the knight on 7四 defends the gold, so the king on 6一 cannot capture it.
