	==== Habu style Sleeve Rook ====		==== Habu style Sleeve Rook ====
			Habu style (羽生流 ''Habu Ryu'' or 羽生式 ''Habu shiki'') is a shape that came up in 2018 Kiousen title match game 3, where [[Yoshiharu Habu]] faced [[Masayuki Toyoshima]]. From the initial position: ☗ P-26 ☖G-32, ☗P-25 ☖R-72.<ref>[https://shogidb2.com/games/29aeeeee1c259dd854796d641361fd639e60d0f4#lnsgk1snl%2F2r3gb1%2Fpp1pppppp%2F2p6%2F7P1%2F9%2FPPPPPPP1P%2F1BG4R1%2FLNS1KGSNL%20b%20-%207 Yoshiharu Habu vs Masayuki Toyoshima] (2018) from ShogiDB2</ref>

			[diag.5-6]

			As shown on diagram 6, after taking 7th file vanguard pawn, Habu pulled his rook into a [[Floating Rook]] position. The point is that Sente is not able to open their bishop's diagonal, making it difficult for them to utilize the bishop.

	==== On ~~move~~ 2. ~~△P-74 Strategy =~~===		=== Gote's Sleeve Rook ===

	A very specific example of Sleeve Rook is [[Sente / Gote\|Gote]]'s P-74. The line goes: P-74 P-34 P-26 P-74. A worth mentioning is next [[Sente / Gote\|Sente]]'s move B-55 which seems to successfully pressure
			==== On move 2. ☖P-74 and 4. ☖P-74 Strategies ====
			A very specific example of Sleeve Rook is [[Sente / Gote\|Gote]]'s ☖P-74 on the 2nd move.

			===== Immediate ☗B-55 =====
			☗P-76 ☖P-74, where worth mentioning is [[Sente / Gote\|Sente]]'s move ☗B-55. Gote won't back off ☖P-34, ☗Bx88+ ☖Sx, ☗S-88 leads to ☖B95! A difficult to defend check: ☗R87 or ☗R*77 - Sente is forced to drop the rook from the hand. A mistake would be ☗S-77 because of ☖Bx(95), ☗Nx ☖Bx+ leads to two for one exchange.

			Which makes ☗R-76 ☖P-74 ~ ☖R-72 a possible strategy for Gote.

			This strategy was first played by [[Osamu Nakamura]]. There is also example of ☖P-74 on the 4th move played by Inoue in an official match.<ref name=":0" />

	In Double Static Rook opening it may be used with Yagura, Gangi and others. The point of the strategy is that the rook targets opponent's king's head directly. Usually right silver will join the attack on the third file.
