Super High Speed Silver-37

In shogi, Super High Speed Silver-37 or Ultra Quick Right Silver (超速3七銀 or 超速▲3七銀 chōsoku san-nana gin) is a rapid attacking formation used with a Static Rook opening by Black often against White's Cheerful Central Rook. It was developed by then-3-dan Yoshitaka Hoshino, who went on to become the second apprentice professional to win the Masuda Award in 2010.

Black aims to advance their right silver through 37 to 46. White likewise can answer Black's advancing silver by moving their left silver to 44.
