I use Tinkercad for the basic generation, and Inkscape to make them site-compliant.

Thanks. I was thinking about making some Chu Shogi SVGs.

I can list off the specification numbers, if you need them.

Shouldn't be too important unless you are using features that are known to be deprecated.

Well, I did use your pieces for a Western set for the Chu Shogi Applet (via fen2.php) using single icons, so if I decide to include pictogram SVGs, I think I'm covered there.

Actually, I think it may be best if I do use your SVGs for a Chu set, if that's okay with you.

I'm sorry, but I cannot get these links to work at all.

I have decided to make my email address public, so you can send the files via an email to me.

Thanks.

All that would be left to do is figure out how to change the color of the SVGs. but I can always use tools in the code to do that.

So far Tinkercad + Inkscape is working beautifully. A bit tedious to be sure, but that was a given by default.

Thanks.

I was thinking about having a short-range burning piece, which burns diagonally adjacent pieces, like what the Fire Dragon does in Minjiku Shogi. This creates the desired power gap while still allowing adequete defense against the power piece, even without jumping sliders. An example is shown below.

Also, I noticed a weird bug where for burning pieces the diagram would stop generating moves early on normal board with no holes if the burning piece gets close enough to the board edge. For an example, go to the Tenjiku Shogi page move one of Sente's Fire Demon towards the top board edge. With enough messing around you should see the highlight generation fritz out when a Fire Demon is highlighted.

I also found another bug where a piece that promotes to a burner doesn't show in the promotion options and then promotes to a white burner if the moving piece was black. Take for example the Chess Knight in the diagram in my last comment.

[Edit]: Pieces that promote to burners upon being asked for promotion choice (at least for Shogi-style promotion) will also burn pieces regardless of whether promotion is accepted or deferred, even if the original piece does not burn.

Since there are several bugs at once, I'll leave you be.

I might post new diagrams of my ideas in the future, for which you can weigh in as you see fit.

My only reservation is that introducing any form of burning makes it more a Tenjiku-Shogi variant than a Dai-Shogi variant. If it was up to me I would prefer to only use moves of a type that are already in Dai Shogi. A quite strong piece without solo-mating capability could be made by enhancing a Queen with linear two-leg moves like exist on the Horned Falcon and Soaring Eagle.

This logic kind of falls flat, since Tengu Dai Shogi does the same thing with hook moves and Lion Dog moves and is still considered a Dai Shogi variant. Queen+Lion could work for the power piece though (I'm no longer concerned about avoiding lone mating as long as there is still some difficulty in doing so).

Tenjiku Shogi also has no anti-trading rules. But I actually played that, and even after trading away the Fire Demons and neutralizing the danger of the jumping generals it remains an enormously tense game, because you can get back a Fire Demon through promotion. Which creates an immediately winning imbalance. The Water Buffalo's themselves are only average pieces (by Tenjuku standards), and are not easily traded. So equiping some less important pieces with decisive promotions might be an alternative to anti-trading for keeping a large game exciting.

It also helps that both the Fire Demon and Water Buffalo come in pairs, and are both sliders.

I discovered one last bug. The highlights of the crosses for the royal pieces and anti-trading rules are no longer being displayed correctly.

Bug Example shown below. To replicate, simply move the Lions close to each other or the King close to an enemy piece.

I think the more important question is whether (some of the) power pieces should be subject to some anti-trading. In original Dai this was not the case, but that could be one of the reasons it was replaced by Chu in terms of popularity. Tenjiku Shogi also has no anti-trading rules. But I actually played that, and even after trading away the Fire Demons and neutralizing the danger of the jumping generals it remains an enormously tense game, because you can get back a Fire Demon through promotion. Which creates an immediately winning imbalance. The Water Buffalo's themselves are only average pieces (by Tenjuku standards), and are not easily traded. So equiping some less important pieces with decisive promotions might be an alternative to anti-trading for keeping a large game exciting.

I think I will go down the Tenjiku path with Reiwa Dai Shogi, but include moves that reference all the moves found in the historical large variants in some way (including Ko and Taikyoku Shogi), but perhaps in more modest amounts. Here are some of my ideas for the new moves:

• Half-Hook Move (RyasRyasW or ByasByasF), a more workable version of the normal Hook Move.
• Jumping Igui (cabS, cabD, cabA, cabN), referencing Ko Shogi's shooting pieces
• Burn (spellZone = F or W)
• Some sort of sliding jump to reference Tenjiku Shogi's jumping sliders
• Some sort of area move to reference Tenjiku Shogi's area move

If the diagram of yours runs in a browser, try looking at the browser console via the right-click + Inspect option (or equivalent). That might help you identify the problem.

If you are using his Interactive Diagrams for your diagram, the following could be helpful. If not, disregard it.

On top of providing the HTML definition you also need to point to the JS script in an HTML script element pointing to it, like so:

<script src="https://www.chessvariants.com/membergraphics/MSinteractive-diagrams/betzaNew.js?nocache=true">

You also have the option of copying the script to a local file for testing without Internet access.

Also, make sure you're copying the whole section when you copy the sourcecode. Missing even a single character can throw things off. For reference, the Diagram starts at <div class="idiagram"> and then ends at its corresponding </div> tag.
