Thanks for catching those typos. They are now fixed. Yes, both the Left General and Right General promote to Shogun.

Nice endeavour. Keep it going please!

Perhaps this is a bit off-topic in this place, but just out of curiosity: can you elaborate a bit on this 'digital implementation'? Does this include an AI, and if so, is this an AlphaZero-type self-learning, or a conventional alpha-beta search (with NNUE or hand-crafted)? It would be very nice if you could create a strong player for games with promotion-on-capture and contageon, such as Maka Dai Dai Shogi, and its shrunken versions. As it is not clear to me what would be a good strategy for such games.

It's already available, you can read about it and find a link here: https://drericsilverman.com/2021/05/13/ancient-shogi-revival-part-ii-the-big-ones/

Everything up to Tai Shogi is now present. Numerous options are available to attempt to encompass the various opinions on rules/piece movements in some of the large Shogis. Where relevant I also included modern variants, like your own Nutty/Cashew/Macadamia series.

There is an AI, but it's basic alpha-beta and not optimised at this point; online play is also available. The Ai Ai software is a general-purpose game-playing package primarily built around MCTS, and the Chess engine is a relatively new addition, so there's still lots of work to do on that. The priority in the Shogi arena right now is having the large Shogis all functional and bug-fixed, then we'll work on the AI. I'm currently working on Taikyoku Shogi.

Reinforcement learning is coming, but not soon. Lots to do until we're ready for that.

@HG,

I face the same issue with my new 12x12 games. There are quite tactical. I can see that but I'm not sure what a good strategy would be. I'm not sure if I'll ever be capable of writing an alpha-zero style program though.

The Left General and Right General's text in the piece listing both say this:

The Drunk Elephant moves as a King except directly left.

Are the promotions right for those pieces, do they both promote to Shogun?

I'm just double-checking because a friend and I are currently working on digital implementations of all the large historic Shogi variants, and once those are finished and bug-fixed I'd like to include at least Suzumu, Hanten and Chushin Shogi as well :)

I don't want to take the time to review this carefully, but it looks good, and I trust the author. So, I'll unhide it without checking it over carefully.

At chariot soldier you probably mean BvRsR2 or BvRsWW2.

Great news!

That's not to say I don't want to make presets for these games. If I could create the proper PHP files for the pieces and get them added to Game Courier, that would allow me to create presets for these games with proper representation of the pieces, which would be great. If you are an editor, perhaps you could help me with that when I finish the PHP files?

I'm not an editor, so far as I know, so unfortunately I can't do much. If there is some way I could help, please let me know.

I'm guessing that, without the added PHP code in Game Courier, the only way to play would be without rules enforcement? That would be doable, but definitely would be prone to error, given the number of piece types.

As for Hanten Shogi and Gyaku-sama Shogi, I am in the process of reviving them.

I'm glad to hear it! I had wondered in the past why the Microshogi/Kyoto promotion methods hadn't seemed to propagate into other Shogi variants, so I was pleased to find Hanten Shogi (and Gyaku-sama).

Game Courier presets for my larger games are theoretically possible. I have the tools necessary, and creating the PHP file shouldn't be that hard, but I am unsure how I would get that to work. The sets that Game Courier currently has either don't have enough pieces, have pieces which don't accurately represent the pieces in my large shogi variants, or have pieces whose names are too complicated for me to effectively implement them into Game Courier.

Looking good so far! Excited to see the final version of this page.

Are you planning to implement Game Courier presets for this, Hook Shogi and Taishin? I would be interested in playing them.

Also, I hope you will revive Hanten Shogi, the use of 'switchback' promotion was very creative.
