Waki System


In shogi, Waki System is a symmetrical Double Fortress opening.
It is characterized in part by positioning Black's bishop on the 46 square and White's bishop on the 64 square allowing for a bishop exchange.
The strategy is named after Kenji Waki.

Development

An early...P-74 is the most common move leading to the standard 24-Move Fortress Set position, which is one of the major branching points of the set of Fortress substrategies.
13. S-37. The Waki System is a silver-37 branch Fortress substrategy.
13....B-64. The Waki System form starts with White moving their bishop to 64 temporarily pinning Black's silver to their rook.
14. B-46. In response, Black opposes White's bishop by moving their own bishop to 46.
This positioning allows the bishops to be traded off in order to place them in hand.
