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 played against a Static Rook opponent.

After White swings their rook to the central file, pushing the second file pawn by Black (4. P-24) in order to trade the pawns off and get a pawn in hand is thought to be a mistake (although not quite a blunder) here since it will result in a position judged to be better for White. (Note the similarity of these lines with the old Central Rook vs Side Pawn joseki.)

After the pawn push and pawn trade off (4. ...Px24, 5. Rx24), since the bishop diagonals are both open, White will trade off the bishops (5. ...Bx88+, 6. Sx88) and drop their bishop forking Black's rook and left silver (6. ...B*33).

If Black plays 7. Rx21+ aggressively capturing White's knight, White replies with 7. ...Bx88+ capturing Black's silver and aiming to bring the promoted bishop back to the 22 square in order to capture Black's promoted rook.

This continuation is believed to be better for White.

In case Black retreats the rook with 7. R-28 after 6. ...B*33, White can play the move 7. ...P*26 aiming for P-27+ to push Black's rook off the second file.
