The Crab Silvers (カニカニ銀 kani kani gin) is a shogi opening. It is a type of Rapid Attack Fortress opening, used mostly when playing Black (sente). It is often classified as a trap opening. It was created by professional shogi player Kōichi Kodama,[1] for which he received the prestigious Kōzō Masuda Award in 2003.

Overview[]

Due to the large amount of freedom of the rook to enter into the game, finding ways to attack even in the middle of a Rapid Attack Fortress has quite the merit.

Unlike the Double-Silver Rapid Attack Fortress, king and gold don't move at all from their initial position (Sitting king). In the fifth movement, rather than pushing P-66, the silver is pushed to S-77. Instead of opting not to push the rook pawn from Fortress, White (gote) will play S-33 following Black's rook pawn being pushed to P-25, which will be followed by ▲S-48, ▲P-56, ▲S-57, ▲S-46. After that, if White (gote) were to push the pawn in the 5th file, the rook will go to the center file with ▲R-58, and then, for example, ▲B-97, ▲S-66, ▲N-77, with the aim of breaking through the center.[2]

Although at first it was frequent for White (gote) to unthinkingly push the gold to △G-32, since it was difficult for Black (sente) to defend from a breakthrough from the center, making preparations beforehand by playing △G61-52 became more frequent. When aiming to attack from the center, pushing the pawn in the 3rd file with ▲P-36 allows the rival to attack the king on its weak points and also delays the attack, so it is often considered a bad move.[3]
