Having had another look at the Okisaki Shogi page, and some others that I found using a search engine, I haven't found one showing the array. I would assume that each Queen would be one the same side of the board as the same player's Bishop, to balance the Rook on the other side. This would give the array
where represents the Rookranker (a Rook that can move forward and backward but not sideways). Does anyone know if this array is correct?

I've just realised, I didn't rate this page in my last comment. Either I forgot or it's grown on me since.
Presumably not, as programming for a piece with a Bishop move but no Rook one would cut into the saving in complexity.
Stating that it is stronger than the Goldgeneral is a simplification. It gets weaker the further forward it moves. Look at what it is once on the eighth rank. By then promotion is more than justified.
Regarding comments of June 2006 (4 year ago!) note the last paragraph of this page.
My instinct is that Xiang Qi is a tamer game, as all but four pieces aside are weaker than the FIDE Bishop and Knight, and once the four are captured they're gone forever. The success of Yang Qi and Ajax Xiang Qi reinforces this view. Shogi counters individual piece weakness partly with 25% more pieces and partly with constant return from capture. This latter element is what makes Shogi particularly interesting to people who already play FIDE Chess and want to go on to something more complex. The fact that it is a development of war without actual death into war without even metaphorical death also gives a sense of logical progression. On the other hand, I wouldn't deny that promoted forms of back-rank pieces would benefit from being a bit stronger.
This variant took a while to appear in the indexing system, but now it is there.
I recently devised a chain of renamings for simple oblique leapers in MAB 03, MAB 05, and MZB 14 that appear never to have been used. The idea seemed so satisfactory that I implemented it without first highlighting that I was planning to, and close on the heels of a series of renamings for compound oblique leapers. Having done it I realise that I have blurred the two changes, so here is a clarification for those who did not notice the second one: It started when I thought of the MUSKRAT and judged this a better name than Myomorph, which in biology includes most of the rodents after which I had named other pieces. However, replacing Myomorph with Muskrat would also require a replacement for Mystic and renaming the Mustang and Muddler. This was not so great a problem, as I was never entirely happy with Mustang anyway. A marsupial name would be much better, to go with the Numbat and Wombat sharing its SOLL of 57. I looked through an online list of marsupials again and spotted the Ringaui. Previously I'd always overlooked Ringaui as it in turn clashed with Irregular. However, once I took a look at a full list of rectlinear oblique leapers I judged it odd that I had given the names of real (if part-time) warriors like the Auxiliary and Irregular to longer-SOLL pieces than those that I had named Bystander and Onlooker. So it occurred to me that a replacement for Irregular could lead to a more extensive chain of renamings addressing these difficulties. First for the 11:6 leaper I decided to use the previously unused S and Y and replace Irregular with SCRYER, someone whose efforts are thought fruitless in modern society. I have never had a name for the FO piece. That freed R and I up, so for the pure-hex piece with SOLL 53 I went ahead with replacing Mustang with RINGAUI. For the FO piece I replaced Escape with GNAWER, following the practice for FO versions of other small-animal pieces. Also freed up was IRREGULAR itself, with which I then replaced Muddler for the 8:7:1 leaper. Note that this switched Irregular to the name of an even- instead of odd-SOLL piece, so that its compounds with radial pieces have different names from those of the old Irregular. The SOLL of 114 is less than the Bystander's 117 and Onlooker's 122. As Mess did not fit this especially well I made the FO Irregular the INSURGENT. That freed M and U up, so for the 8:2:1 leaper from I went ahead with replacing Myomorph with MUSKRAT. For the FO piece I replaced Mourner with SUMMONER. Also freed up were MUDDLER and MESS, with which I then replaced Mystic and Initiate for the 8:7:5 leaper and its FO version. That freed up MYSTIC, someone else whose efforts are thought fruitless in modern society, with which I then replaced Auxiliary for the 11:4 leaper. Note that this switched Mystic to the name of an odd- instead of even-SOLL piece, so that its compounds with radial pieces have different names from those of the old Mystic. I have never had a name for the FO piece. That freed up AUXILIARY, with which I then replaced the unsatisfactory Stretcher for the 7:6:4 leaper. Its SOLL, 101, is less than the new Irregular's 114. As Splint no longer suited the FO piece I made the FO Auxiliary the ANCILLARY.
'In fact, a move from Ea5 to Cb4, one square along a 2-D diagonal and then two cells vertically, is a move that no piece in this game can make. A new 3-D, knightlike piece would have to be invented for that.' It had been. There is no general consensus on its name, but problematists call it a Sexton.
Well one cluster that comes to mind is those applying Shogi rules to non-Shogi games. To the established Chessgi I have added not only Bishogi but also my Frontofhouse, Mitred, and Horn Rimmed variants.
Could someone do the necessary things for this page. I originally posated it two weeks ago and nothing that I can do displays either the page or comments on it.
I too had a similar idea but never finalised the rules enough to post it. My idea was four ranks on the FIDE side, five each on the Shogi and XQ, FIDE facing each of the other two on four files, and Shogi facing XQ on five files. XQ would certainly move first.
'like a diagonal path, but not colour-bound' Depends how you colour the board! The cubic Unicorn certainly is bound, to a quarter of the board, but that quarter comprises a quarter of each Bishop binding rather than half of just one. The intersection of the two kinds of binding (one eighth of the board) is the Dabbaba binding on a cubic board.
Take a look at the name of the AgBank chairman here.
The comment about Eastern games having a lower piece density applies, at least as national standard games goes, only to the Chinese and Korean ones. The Burmese, Mongolian, and Thai ones all have the same board and size of armies that European forms of Chess inherited from Shatranj. Shogi, despite its larger board, has very nearly a 50% piece density, and more or less retains it as the pieces keep coming back - what one reference book describes as preventing the kind of endgame to which Europeans are used. So if we are to learn anything from the East to apply to 3d Chess, it should perhaps be to allow captured pieces to return, to maintain enough strength to bring Checkmate about.
The nearest thing to what you describe is the geometry used in Tetrahedral Chess, which has hex planes in four directions and rectilinear planes in three. It certainly has more symmetries than the hex-prism geometry.
Any news on the update here?
Orthogonal Draughts has always struck me as a variant best played on a corner orientation, in order to have two diferent 'forward' directions rather than introduce a reversible pair of 'sideways' ones. This is illustrated on my Cornucopia of 9x9 Corner Variants page. Another approach is a Wellisch-orientated hex board, as illustrated on my Compact Hex Chess page.
While thinking about a future variant of my own, it occurred to me that the name Karagi ('empty board game') would suit a game starting with an empty Shogi board and a complete Shogi army in each player's Reserve. Each player's first move would be to place their King, their second to either move the King or place a second piece, and later moves the standard Shogi-midgame choice of moving a piece on the board or adding another from Reserve. Adding this deployment stage would be a more modest variant to Shogi, which already has a Reserve and placement of piece from it, than it has been to the European game.
Not only does the extra file unbind the Bishop, it also allows the Knight to lose the move in 5 moves e.g. a1-c2-e1-g2-i3-a1.
Sorry to be pedantic, but... Are the three occurrences of 'when' in the intro meant to be 'then'? The sentence would make more sense with 'then'. 'Pawns may promote any piece, used here, expect king.' As written, this is not fully explained. When does promotion take place and what, for example, does a Pawn promote a Bishop to? Or do you mean 'Pawns may be promoted to any piece, used here, expect king.' - in which case it would be understood that this happens on the far rank unless otherwise stated?
What if a particular game on a cylindical 8x8 board bans null moves (in that case, a Rook moving an exact multiple of 8 steps)? Would a Halfling Rook on such a board be barred from moving any multiple of 4 steps? Or would it be able to round up half a 7-step move to 4 steps - and half a 15-step move to 8 steps? If the latter, the Halfling Rook would actually be stronger than the standard Rook! Perhaps the Rook would have to be made Halfling first and the null move ban then be applied.
It's not surprising that the idea of Shogi with a deployment stage has appeared before. Interestring to note how Unachess has several options for a FIDE set and board but only one for a Shogi set and board. What Unashogi lacks is my proposal that Kings must be placed first, a rule that leads into a theoretically possible Shogi position (although in reality players would be unlikely to hold all there captives in Reserve for so long) so that thereafter Shogi rules can apply as standard. As I write a further thought has occurred to me. The Unachess principle could be used for deploying a set on a board for which it was not designed - a FIDE set on a Shogi board, a Carrera/Bird/Capablanca set on a Xiang Qi board, a Chaturanga set on a Diana/Haynie's Primary/Los Alamos board, et cetera. Of course deploying a Shogi set on a board with more or fewer than 9 ranks would require a definition of the promotion zone, likewise the River and Fortress for a Xiang Qi set.
That's true, and you'd then have an enlarged and compounded version of Makruk. I'm not sure what you'd call such a game, or even the compound of Knight and Silver. Strange that getting that much closer to Australia results in losing the Kangaroo! Currently I'm finalising a topically-themed game, but I had already planned to make my next game after that a Xiang Qi with compounds, including a stepping version of the Kangaroo, and no Ferzes. Look out for it in the next few weeks.
Good idea, it would also work with Yonin Shogi and 125% Shogi.
