This is my first ever formally submitted game. Apologies on the formatting of the post. I'm new to the forum so I'll try to clean up the format and figure out how to put pictures.

I agree that this looks interesting.

I've moved the discussion over from the homepage to comments here.  I've made the link description more descriptive, and corrected some of the categories (your choices were understandable, but most of them mean something different here; something we should clarify).  The formatting of this page should be cleaned up; I can do it later if you're not up to it.

[I'm intrigued and it looks cool, but confused by the knight being a bishop + pawn.  I suppose so many things are breaking apart and coming back together that its value doesn't have to always match the sum of its parts.  Maybe the knights are used at opportunistic times only?  Shout out to Furgus Duniho for the very similar Fusion Chess, but I'll grant that this adds pawns into the mix (and I love how the openings play out), and I also like the visual simplicity of literally adding the rings together.]

Turnover, like chess, goes beyond a simple game, it has esoteric symbolisms. Castle made by 3 pieces has the symbolism of number 3. Keep board with 8x8 squares has the symbolism of number 7 and tetraktis 4+3+2+1 etc. Bishop is the magical or spiritual piece of chess, and it moves like a cross to bring a lot of other symbolisms that confirms the esoteric value of chess. Bishop + Pawn = knight because it is a man (pawn) with power (spiritual power from bishop), so in medieval battle, knights is it, a man mounted in a horse is much more stronger.

 

If you play the game, you will realise its difference on tactics, because you are sharing pieces with opponent. It create a kind of statu quo between pieces and it is really interesting. New players of course will play trash matches, but good turnover players can make passionate matches, and I swear, is really almost impossible to draw in Turnover, because this game is very offensive. So, yes, is very dangerous create knights, because bishops are very useful and when you move a knight you let behind a bishop and the opponent can think a strategy to take your bishop.

About simplicity, the game uses only 3 pieces, a magical number and a strong algorithm to the way human mind works. So when you are playing the game, seems all possible moves from all pieces on board can be visualized in your mind and it is good, because your mind can dedicate more time to think what move instead of recognize pieces first to think what move after. And your mind stress less then in chess.

  • Pawn moves ahead one square and take diagonal forward one square. Pawn turnover ahead one square.
  • Yes, is illegal to split up your last Castle, but if you have the last castle in check and it can turnover a queen ahead to get free from check so you can do it.
  • Good question. Capture the opponent's last Castle by splitting up your own last Castle is a illegal move, because the result is no castles on board.
  • "Does a promotion reset the 50-move counter?" It works like it on traditional chess? I don't know, but seems interesting question, I vote to reset :)
  • "Does combining friendly pieces count as a turnover, for resetting the 50-move count?" No. Combining friendly pieces is not turnover, because a turnover is a take possession, like turnover in american football.

I share the concern of Joseph DiMuro: this game should not be winnable except against the most incompetent of players. It would need some rule that you cannot move a royal slider through check, like in Caissa Brittannia, to make it a serious game.

Indeed, the particular combinations of rings that you have at any moment is not really preserved for a long time, nor hard to improve when sub-optimal. Piece values only have meaning in more conventional chess games because you typically will be stuck with a piece for a very long time, possibly to the end of the game, and if you have a weaker piece there is not much you can do to trade it for something more valuable. Here the actual combination is more like a positional advantage. Temporarily having the Bishop lose its moves by combining it with a Pawn is similar to blocking a good diagonal for a Bishop with a Pawn in orthodox Chess. (The Bishop might keep some of its other moves in that case, but here the 'Pawn' will temporarily acquire Knight ability, which should provide even better compensation.)

Yet you probably would not strive for combining your own Bishops with a Pawn. But remember that you can also 'turnover' an enemy Bishop by merging it with your Pawn, and that would be extremely advantageous, as now it is the opponent that loses the Bishop, and won't get it back when you split them up again. It would in fact be pretty hard for him to get it back at all. So it is really the value of the individual rings that play the role of piece values here.

Looks like an interesting game, although I am not sure it qualifies as a chess variant. Could you explain the rules? They are not on a pubicly accessible website, in so far I could find.

[Edit] Oh, I found a description in a PDF file on Google Drive. Some things are not yet clear to me, though:

  • It says the Pawn only moves one step. But is this only forward, or can it also move backward, when going to an empty square?
  • It says the win is by taking or turning all enemy Castles. But Castles can also be destroyed by their owner, through splitting them up. Which is neither taking nor turning.) Is it illegal to split up your last Castle?
  • What if I capture my opponent's last Castle by splitting up my own last Castle? Is this allowed? And if not, who would be at fault? Is it more forbidden to split up the last Castle, or more forbidden to move into its capture range?
  • Does a promotion reset the 50-move counter?
  • Does combining friendly pieces count as a turnover, for resetting the 50-move count?

erik I'll look into creating one.  I'm admittedly not too familiar with Game Courier.  At the moment, for online playing I've been using a "sandbox" environment without rule enforcement.  I'd be happy to work something out so we can play a game (or if necessary, even using a video stream of the board, with moves entered in the chat box or something).  If you find anyone on your end interested in playing over the board, I'd love to know how the game went (try to record it!)

This game looks interesting. It would be good if it had a Game Courier preset.


Jeffrey T. Kubach wrote on 2019-06-14 UTC

Rules have been updated to include revised abilities on the sentry piece.  It will add a more unique feel to the game than the original sentry (which was too ineffective in closed positions- even moreso than a bishop).

Bughouse tournaments seem to be happening all the time now, at least in North America (especially at scholastic level) - anyone who might want to organize chess variant(s) events over-the-board could start with having bughouse games/events; here's a link that shows what happened when I Googled 2019 Bughouse tournaments USA:

I see your point about priorities HG. I was not picking on you. Good job. I was only pointing it out!


Aurelian Florea wrote on 2019-06-09 UTC

In the link you had posed, 2d was not kanji. And even if it were, I'd at least be able to memorise pieces easier.


H. G. Muller wrote on 2019-06-08 UTC

Yeah, the Jocly 3d graphics run quite slow when you don't have a GPU (as is apparently the case on the virtual machine where I run Linux). I was a bit in a hurry to at least get the AI working, because I had entered it in the yearly Modern Tenjiku correspondence championship, and its clock was already running, and had ticked away 96 of the available 120 days. So I didn't pay any attention to non-essential details, as I normally would.

BTW, 2d would not solve the kanji problem...


Aurelian Florea wrote on 2019-06-08 UTC

To me the trouble is that the 2d display is more feasable. The 3d one consumes a lot of resources.

Also I don't reconnize all the required kanji!


H. G. Muller wrote on 2019-06-08 UTC

Ah yes, I only payed attention to the 3d display. Yet the 2d display is always important, as the images for that are also used in 3d for the promotion popup, which asks you whether you want to promoe or defer.

When I have more time I will make a file with images of all Shogi pieces.

Hope I don't trouble you too much HG!...

In 2D mode most pictures are not shown properly, but I'm not sure you've got there!...


H. G. Muller wrote on 2019-06-06 UTC

I made an attempt to implement Tenjiku Shogi in Jocly. I even spent some time on the evaluation function. As a result it actually seems to play a reasonable game at 30 sec/move, despite its low search depth. (Jocly's generic JavaScript AI is not very fast.) The web applet can be found at:

While watching a cpu vs cpu game of eurasian I had noticed that vaos do not seem to care either about color binding as in the early game color binding is compensated by the other pieces and in the late game lack of platforms probably damages them more.

Cool analisys HG!...


H. G. Muller wrote on 2019-05-31 UTC

Well, it is difficult to asses whether this capability for a pair to statically create an impenetrable barrier for a King is really important. Actually I think that Wizards can just do it (on 8x8), when standing next to each other in the center. But very often pieces can inflict a 'dynamic confinement' on a King. As long as you have to spend fewer moves to maintain it than the King needs to escape, you have moves to spare for other pieces to approach. Besides, FAD complement each other in a different way: standing next to each other the completely cover a 5x6 area, As a result they can drive a King to the edge with checks, and checkmate it there, without any help. This makes them very, very dangerous.

Even a King + Bishop can dynamically confine a King on boards of any size. The King has to cover the hole through which the opponent threatens to escape, and has to follow the bare King as long as it keeps running in the same direction to renew the escape threat. But when it reverses direction, to try an escape on the other side (which he eventually must, as he bumps into the edge) you have one free move. Therefore a Bishop can checkmate together with an arbitrarily weak piece (as long as that can go everywhere) on boards of any size.
