▲6二銀
Why this move works
The answer is ▲6二銀, working together with the gold already on 6三. The dropped silver covers the two squares in front (5一, 7一), while the gold behind it covers the two diagonal squares (5二, 7二).
The silver is protected by the gold, so it cannot be taken, and all of the king’s escape squares are sealed. One piece is not enough here — overlapping the reach of two pieces is what delivers mate.
