In shogi, Fourth File Rook (四間飛車 shikenbisha) or Golden Rook (金飛車 kinbisha) is a class of Ranging Rook (振り飛車) openings (戦法) in which the rook (飛) is initially positioned on the fourth file if played by White (後手) or the sixth file if played by Black (先手).

It can be called golden rook because the rook moves to the file where initially the gold is.

History

The earliest recorded shogi game was a Static Rook vs. Fourth File Rook game from 1607. Black was Sōkei Ōhashi I who played a Right Fourth File Rook position (Static Rook) against Sansa Hon'inbō's Fourth File Rook. Ōhashi won the game.

The opening starts by the usual four-move sequence that characterizes Static Rook vs Ranging Rook (居飛車対振り飛車) games as shown in the first adjacent board position. (See: Traditional Ranging Rook.)

3. S-4h. Black advances their right silver up and toward the center of the board. (This is a more flexible move than 3. S-3h.)

3. ... S-4b. White likewise moves their silver up. This left silver will likely be a main component of White's counterattack.
