Ratings & Comments
Since many of these award sites or programs are defunct, I used the Wayback Machine to search for the pages that actually mention the Chess Variant Pages, and when I found one, I changed the link to an archived version of that page. After all, displaying awards is more meaningful if we can document that we actually got the awards.
This sounds a lot like 'Extinction Chess'...
Very nice touchup of the page. You might have mentioned that in problems, there is more than one way to use the cylinder concept. The one here described is chess on a horizontal cylinder, which is the only form that is playable as a game. Other forms have appeared in problems: the vertical cylinder with the first and last ranks connected and the anchor ring both basically both a vertical and horizontal cylinder simultaneously. In the latter case, a1 is connected to both a8 and h1 (and in some version h8 as well, if you really want to go crazy). With rooks and queens instantly attacking each other and the kings in mutual check, we'd need special rules to play this, but a KBB vs K ending on such a board can be analyzed, as well as more complex problems.

OK I've edited that
I have saved the new images that I hope will be the correct size now. Here's hoping it worked...
I read on the wiki talk page for Tenjiku about the idea that jumping generals could have been intended to do more than just jump-capture.
The start position shows the generals in front of the Fire Demons, both straight ahead and diagonally. There is no opportunity for jumping generals to capture Fire Demons in the start position, which is intentional.
It doesn't seem right that there is so much protection for Fire Demons, yet in some versions of the game, the King could be threatened and captured without even being able to evade the attack, as it's boxed in.
(In fact, the Bishop General could just mate the opponent's King on the first move if there were no restrictions on jumping.)
If the generals could jump whenever they wanted as far as they liked, the game would become even more tactically sharp than it already is. However, it doesn't break the game.
The Great General can't jump two squares diagonally to threaten one of the Fire Demons as the Rook General would capture it.
The best the Bishop Generals can do is to manoeuvre and attack a Horned Falcon or Soaring Eagle.
The idea that jumping generals could capture all of the opposing pieces they jumped over in one turn is plausible. I don't know if the game would break, but the inventor(s) of Tenjiku weren't sentimental about pieces — allowing Fire Demons to punch large holes into positions — so having more pieces do the same seems logical.
The Great General could just capture the Vice General; Free Eagle; Queen; Drunk Elephant; and a Pawn on the first move (with check). This doesn't seem intentional.
One of the Bishop Generals could move to the edge of the board and threaten to capture a Soaring Eagle; Water Buffalo; Phoenix; Drunk Elephant; and a Pawn. The Soaring Eagle can leap out of the way, though.
Otherwise, everything is sufficiently well defended that jumping generals couldn't capture a total of anything worth more than themselves, as they are even stronger than their current form.
That could be why Fire Demons are so powerful — with burning and sliding and an area move — because they would be ecliped otherwise by the jumping generals.
The board size (16×16) and large number of pieces that do very little makes more sense if there were even more crazy pieces. The game might devolve into a capture-fest, but that might have been the intention.
Whoever had the imagination to create this game has to be admired. I consider this to be the most ambitious of all the historical variants as its construction is so delicately balanced, even with the ambiguity in the rules themselves.
I didn't know that Excel could be used for making board diagrams. Anyway, the closest thing I have to Excel is LibreOffice Calc, and I've never used it that way. Paint.net will let you resize images using the Resize menu item in the Image menu. You may also use the keyboard shortcut of Ctrl-R.
Since Ai Ai beat the Interactive Diagram at its default settings, I raised the Interactive Diagram to 4 plies and tried again. This game ended in a draw by three-times repetition, as called by Ai Ai at move 60. Apart from that, the Interactive Diagram was ahead in material and might have won with better endgame play. Here's the MGS file from Ai Ai: ID4-vs-AiAi-Chess.mgs. At move 60, I let the Interactive Diagram, which had been playing White, continue as Black, and I took over as White, eventually checkmating Black.

I have tried to re-size the boards one more time. If this still does not work, please let me know what I can do to fix it. Thank you for your patience with my lack of technical acumen!
I am not sure what to do to correct this problem. All I did to make the images was to copy the image out of Excel and paste it into Paint.net and save it. I am not an uber-technical computer user and I truly do not know how to fix the number of pixels in an image. I am more than willing to make any fixes that I can, but to do this one myself would require some clear and simple instructions from someone who knows how to do it...
Since Ai Ai and Ludii both use Java, I ran a game of Chess against them. Ai Ai won. Since Ai Ai and Zillions-of-Games both run on the computer, I also ran a game between them. Zillions-of-Games won this one. I have uploaded the MGS files Ai Ai records games in: Ludii-vs-AiAi-at-Chess.mgs and ZoG-vs-AIAi-Chess.mgs.
I then ran a game between the Interactive Diagram and Ai Ai. This was a very close game, eventually coming down to a Pawn race in which Ai Ai had a Rook and two Pawns, and the Interactive Diagram had a Bishop and two Pawns. Ai Ai eventually won: ID-vs-AiAi-Chess.mgs

In Ludii vs Biased UBFM, the game was a draw through three-times repetition. It was more interesting, because White kept chasing the King with its Queen while Black had two connected Rooks and a passed Pawn. I eventually took over for White and won, but it was probably due to Biased UBFM's bad playing.

Ludii drew UBFM by three-times repetition, maybe not too surprising since Ludii is more fully called Ludii (UBFM). The surprising thing is how UBFM flubbed up the endgame. It had both a Queen and a Rook against the King, and instead of quickly going for checkmate, it kept repeating the same Rook moves back and forth while the King kept going back and forth.

For some reason, I couldn't find the Ludii Player on my computer today. So, I downloaded it again and noted that it was in my Downloads folder before running it. It is just a .jar file and doesn't install anything.
Continuing to use it, EPT-QB quickly beat Ludii. The ironic thing is that EPT-QB made a terrible move, exposing its Queen to en prise capture by either the Bishop or the Queen, and instead of taking the Queen, Ludii just moved its Queen beside it. Then EPT-QB captured the Bishop for checkmate.

For reference, Betza has a (unofficial/untested?) Chess-with-different-armies team with an amazon; he just limits the rooks to R4 and keeps the other pieces:
https://www.chessvariants.org/d.betza/chessvar/cvda/amazon.html
The reported search depths for alpha-beta are absurdly low. Most engines would reach such depths faster than a millisecond. So there doesn't seem to be a reason to stop there. In one place it even reports a depth of 0. Either it lies about its depth, or ther is something very wrong with this alpha-beta implementation.
This is extremely unbalanced. An Amazon is only worth as much as a Queen plus a Knight, and the ability to castle or e.p. capture is of no significant value. So it is like black is three minors ahead, amongst which the Bishop pair.

I'm done for the night.
Since the Ludii Player has many engines (or agents) to choose from, I had it do an analysis to find the best player for Chess. The analysis was quick, and it said "Best predicted agent is AlphaBeta". But I already found that it played poorly against Ludii. In case more thinking time would eventually give Alpha-Beta an edge, I increased the thinking time to 5 seconds for another game between Ludii as White and Alpha-Beta as Black. Ludii won this game with checkmate. During the game, it showed an analysis of each engine, and Ludii, identified here as UBFM consistently had a higher search depth than Alpha-Beta.
UBFM (player 1) completed an analysis that reached at some point a depth of 4:
best value observed at root 0.13999999,
1196 different states were evaluated
50 iterations, with 134 calls of minimax
Alpha-Beta (player 2) completed search of depth 2.
UBFM (player 1) completed an analysis that reached at some point a depth of 3:
best value observed at root 0.20000005,
