▲６二金
Why this move works
The answer is the head gold ▲６二金, this time protected by the silver on the other side at 5一. The king cannot take the gold, and the squares 5二, 7一, 7二 are all covered.
Square 5一 is blocked by the silver, so the king is mated. The supporting piece sits in a different spot, but the head-gold idea is exactly the same.
