In shogi, Snowroof or Snow Roof Fortress (雁木 gangi, lit. 'goose-wooden') is a Static Rook opening that characteristically uses a Snowroof castle.
It is named after the covered sidewalks (雁木造) connected to buildings in Niigata Prefecture.
Originating in the Edo period, the opening had been a less common one after World War II although it was popular in the prewar era. However, around 2017, the opening has become popular with professional shogi players.[2] The Snowroof structure often appears in computer shogi games.
