▲３三銀 △３一玉 ▲３二銀打
Why this move works
The answer is ▲３三銀 △３一玉 ▲３二銀打. The king flees the silver check to 3一, and ▲３二銀打 finishes.
The front silver (3二) covers 2一 and 4一, while the rear silver (3三) covers 2二 and 4二, and the two silvers protect each other. Unlike golds, silvers reach diagonally — a nice example of two silvers alone sealing every escape.
