Cheerful Central Rook

In shogi, Cheerful Central Rook (ゴキゲン中飛車 gokigen nakabisha, also Gokigen Central Rook or Go-As-You-Please Central Rook) is a type of Central Rook opening in which the Central Rook player's bishop diagonal remains open. This is a more aggressive strategy since the bishops may be exchanged at any time during the opening. (See: Ranging Rook#Types of Ranging Rook.)

Cheerful Central Rook is typically played against a Static Rook opponent.

Pushing the second file pawn by Black is a mistake here since: 1. P-2d Px2d, 2.Rx2d Bx8h+, 3. Sx8h B*3c forking the rook and the silver. If Black plays RxN+ White replies with BxS+ and aims to retreat the Bishop at 2b to capture the dragon.

This continuation is believed to be good for White.

In case Black retreats the rook after B*3c, White can play the move P-*26 aiming for P-27+.

Gote usually aims for an Incomplete Mino castle:

However, there is always the option of an Anaguma castle as well.
