In shogi, Retreating Rook (引き飛車 hikihisha) is a variant of the Double Wing Attack (相掛かり aigakari) opening and joseki in which Black's rook retreats all the way back to their camp after a pawn exchange in the eighth file allowing White to also exchange rook pawns.
Development
6. R-2h. Black's retreats back to their camp on the h rank.
6. ... P-8f, 7. Px8f Rx8f, 8. P*8g .... After Black's rook has retreated, White plays a similar sequences of moves: pawn exchange and a pawn drop by Black.
After move 15, White has a similar choice to retreat their rook back to their camp (8b) or to move it to a floating rook position (8d).
The floating rook position defends the d rank from further encroachment by Black. Note that if White retreats their rook to 8b, then, compared to the start of the game, these 16 moves have effectively only done two things: (a) each player's rook pawn have been placed in hand and (b) each gold is defending the bishop pawn. The floating rook is the more common variant and is shown below.
8. ... R-8d. White floats their rook to the d rank.
9. S-3h P-3d. After White's floating rook, Black moves their right silver up and White moves their third file pawn to open their bishop's diagonal.
Climbing Silver
After White's move, a common variant of Double Wing Attack Retreating Rook is for Black to play Climbing Silver.
