Unidirectional arrays on standard boards

Following John Smith's criticism that Shogi is too "forward" for this treatment and encouragement to do something about it, I have decided to give the Shogi variant the modest variation SAINTED SHOGI. This has no array Rook, substituting a second Bishop in face-to-face Shogi. Most pieces are promoted by adding the move of the XQ piece in the corresponding position. An exception is that Points, which are common to both, are promoted to Wazirs, a compromise between what they are promoted to in the two standard games. Sainted Shogi is a game especially suited to armies moving in parallel and therefore, on the normal Shogi board, to a Moebius interpretation in which the each rank wraps round not to itself but to the corresponding enemy rank. In fact it is one of the few variants for which Moebius treament does not place any pieces starting En Prise.

I have also decided to modify XQ promotion with the modest variation FURTHER-PROMOTION XIANG QI, in which a promoted Point can optionally be further promoted to a captured stronger piece at the end of a move along the far rank.

If anyone wants to write an implementation for either Sainted Shogi or Further-Promotion Xiang Qi as variants of the standard games, feel free to do so but please credit me. Regarding the main feature, again feel free to write implementations, crediting me and, where known and noted below, the inventor of the original face-to-face game.

Rules

Promotion rules are inherited from the face-to-face variants, albeit in an initially empty part of the board rather than the enemy camp, and to nonstandard pieces in the Shogi case. Also inherited from relevant variants are any River/Fortress restrictions (but confined to the same side of the River, cf Tardis Taijitu), Reintroduction rules (always unpromoted), or King swaps.

In all variants Knights, whether leaping or stepping, may not move directly between their first and second ranks. On the FIDE board this is to prevent instant Checkmate, but on others it prevents early captures. There is no equivalent restriction for the two furthest ranks, as none is needed.

XQ Fortresses are moved to the corner 3x3 areas. As well as confining the General and Ferz, I lift the requirement for pass-through squares within the Fortress to be empty. This is again to prevent instant Checkmate. Think of it as a multi-storey Fortress if you like. That gave me another idea which saw fruition as Qiube.

Check, Checkmate, and Stalemate are as in the face-to-face variants.
