Openings · 戦法
Ninety-one openings, and where to start.
A shogi opening is a plan for where the rook and the king go, and everything else follows from that. This is every opening the site covers: thirty-five that swing the rook to the left, fifty-six that keep it at home, each with a move order you can step through on the board, the castle it goes with, and what to do once it is built.
The one question: where is your rook?
Every opening in shogi belongs to one of two families. In a static rook opening (居飛車, ibisha) the rook stays on its starting file and the king castles on the left. In a ranging rook opening (振り飛車, furibisha) the rook swings to the centre or the left and the king castles on the right. Decide that by move five, choose the castle that goes with it, and the rest of the opening is development.
Ranging rook: the rook swings left
Thirty-five openings, listed by family. The Fourth File Rook comes first, with Ōhashi’s Yōryū form, which stops the king on 3h; its bishop-exchange forms, the Bishop Exchange Fourth File Rook, White’s Leghorn Special and White’s Tateishi, which ends as an Ishida; the Fujii System, which attacks with the king still at home; and White’s King’s Head Silver against a rapid attack.
Then the Third File Rook family: the Ishida, Masuda’s Ishida, the Quick Ishida and Suzuki’s New Ishida, the two openings that swing the rook on the first or the second move, and White’s Fourth-to-Third File Rook and Sugai Third File Rook.
Then the Central Rook, with White’s Silver Horns and Cheerful Central Rooks, the Primitive Central Rook that attacks at once, and White’s Left Anaguma; the Opposing Rook, with its American, Direct and Sakata forms; the Double Ranging Rook, which is what happens when both players swing, with White’s Kimokimo Gold against the Ishida; and the surprises: the Demon Killer and its Opposing Rook cousin, the Wrong Diagonal Bishop, the Bishop Head Pawn for either side, White’s two traps, the Pac-Man and the Tonari, and the Ninth File Rook.
Learn the Fourth File Rook properly first: the Third File, Central and Opposing Rooks castle the same way, with the rook a file or two along.
Static rook: the rook stays home
Fifty-six openings, and they share much less. The rook keeps its own file and the king castles on the left, but where the attack comes from is the whole question. The first group is played against another static rook.
The Yagura comes first, with the lines that grow out of it: for Black the Silver-37, the Waki and Morishita Systems and Spearing the Sparrow, and Crab Silvers and the Static Bishop Left Mino Rapid Attack, which attack a Yagura without building one; for White the Yonenaga, Nakahara and Akutsu Rapid Attack Yagura and the Yagura Central Rook.
Then the Climbing Silver; the Bishop Exchange with its Reclining Silver, the Kimura Joseki that grows out of it, and its Rushing Silver and Tempo Loss forms; the Right King, which castles on the rook’s side; the Double Wing with Nakahara’s Rushing Silver, the UFO Silver, the Tsukada Special and the Twisting Rook, which ends as an Ishida; and the Side Pawn Capture with its lines, White’s Bishop-33 and Chūza’s Rook, Black’s Aono and Yūki answers to them, and White’s Knight-33, Bishop*45, Double Side Pawn Capture and Pawn*23.
Most of these only happen if both players go along with them, and the games turn sharp early.
The second group answers a ranging rook: the Static Rook Anaguma, the Iijima Bishop Pullback and the Subway Rook for a slow game, and the King’s Head and Center Vanguard Pawns, which take space in front of the castle; then the rapid attacks from a Boat castle (the Left Silver-46, the Yamada and Saginomiya Joseki, the Pawn-45 Early Fight, the Right Silver-46, the Ponpon Knight and the Bird Catcher), the Left Mino Rapid Attack, which plays the same attack from a stronger castle, and the Right Fourth File Rook in its rapid-attack and Left Mino forms; White’s Sleeve Rook and Climbing Gold against the Ishida; and the Super High Speed Silver against the Cheerful Central Rook.
The surprises come last: the Ureshino and the Murata System, which keep the bishop’s diagonal closed, the Kamaitachi in its 19-move line and against a Fourth File Rook, White’s No Guard, and the First File Rook.
Which to learn first
If you like to wait for the other side to commit, the Fourth File Rook: it is a system, the same moves every game, and the Mino castle comes free with it. If you like to attack, the Climbing Silver: it is the plainest attack in the game and it teaches how three pieces on one square break a position. Play one of the two for fifty games before you look at the others. The bot’s search levels play the Fourth File Rook and the Yagura from their book, and the Mino levels play what people play, so you will see both across the table.
