Subway Rook (地下鉄飛車 chikatetsubisha) is an uncommon Static Rook shogi opening with the rook on the bottom rank 9 (or rank 1 for White) that supports an attack on the ninth file.

Static Rook openings in shogi typically have the player's rook at its start position, which is the second file for Black and the eighth file for White.

A shogi opening is the sequence of initial moves of a shogi game before the middle game. The more general Japanese term for the beginning of the game is 序盤 joban.

It may be useful against an opponent playing a Ranging Rook Anaguma position.

Ranging Rook or Swinging Rook openings in shogi position the rook to the center or left of the player's board to support an attack there.

The name comes from the way the rook moves from second file to the ninth file on the bottom rank as if it were an underground subway.

This bottom rank positioning of the rook is shared by a few other strategies such as the Pinwheel and Right King openings.

In shogi, the Pinwheel is a uncommon opening with the rook on the bottom rank 9 enabling it to switch between a Ranging Rook and Static Rook attack.

In shogi, Right King or Right-hand King is a defensive subcomponent of different openings in which the king stays on the right side of board along with rook, which protects the last rank 9 as well as the eighth file. It is an exception to the general rule that the king is castled away from the rook.

Overview

It's an attack opening used against Ranging Rook Anaguma and Right King. Starting with Black's moving the knight to 85, it's a powerful attack concentrated on 93 by rook, bishop, left knight and left lance. It's particularly effective against Anaguma, since the king has no escape route and it's possible to do checkmate in one gulp. In addition, in a Double Static Rook if the rival uses Right King, it's possible to start the attack in a location close to that king.

The Anaguma or Bear In The Hole is a castle used in shogi. It is commonly used in professional shogi.

Although boasting superb defense power, this opening requires moving almost all pieces from the 1st to the 2nd rank, which takes a lot of moves, and also makes the formation constrained. For this reason, this opening is seldom used.
