Bishop Exchange Fourth File Rook
In shogi, Bishop Exchange Fourth File Rook (角交換四間飛車 kaku kōkan shikenbisha) or Open Bishop Diagonal Fourth File Rook (角道オープン四間飛車 kaku michi ōpen shikenbisha) is a Fourth File Rook (Ranging Rook) opening in which the player's bishop diagonal remains open allowing for a bishop exchange to occur early in the opening.
This contrasts with the defensive so-called normal or standard Fourth File Rook that keeps the bishop diagonal closed until the player is ready for a counterattack so that they may avoid rough and tumble battles initiated by their opponent. (See: Types of Ranging Rook.)
