Well, because of the acclamation then:

Oppulent Chess

I've played the heck out of this via Ai Ai, and I absolutely adore this game. I prefer the greater piece density and the more interesting piece mix here to those of Grand Chess. The resulting play is interesting and nuanced both tactically and strategically. In my opinion Opulent Chess is one of the finest 10x10 variants.

My one complaint is the presence of Pawn promotion by replacement, but that's not particular to this game, I just dislike it everywhere. Promoting stuff is fun and interesting, so I prefer just being able to promote to any piece without restriction. After all I'm a Shogi player, and what can I say, we like promoting stuff! I also dislike some of the weird effects the rule can produce in rare circumstances, but that's more of an aesthetic objection. I do like the extended promotion zone though.

On the whole, a delightful game. Strongly recommended to anyone with an interest in decimal variants.

Yes, I will be updating the GC presets.  I just want to modify them to use the new fairychess include file while I'm at it and did not get that finished last weekend.  But we have a 3-day weekend coming up so it should get finished.

That table of piece values is quite old so I wouldn't put any stock in it.  Probably doesn't match at all with what I am currently using in ChessV (which gets updated more often.)  The Archbishop is too low probably because I was relying on Betza's logic which significantly undervalues it, but I would not claim that these values are what he would have calculated.  Also, the table shows the value of sliding pieces going up in the endgame, which made sense since there are less obstructions, but seems to not actually be true in most cases.  (The value of the Pawn going up is true, though.)

@ Greg:

1) Now that the setup for Opulent Chess has been changed from the original, are there definite plans to change the preset to match the new setup anytime soon?

2) On the piece values offered, the one for the Archbishop being 7.5 (and Q=10) stands out. Does the table of values entirely concur with what Betza himself might have calculated for the piece values of Opulent Chess, for on 10x10, with the given armies in the setup?

Some pretty strong and interesting pieces in this variant, which helps on its large board.

I saw that David added some names for the NW compound seven years ago.

Here are a few more names for the same piece: Thoat (from Jetan, Edgar Rice Burroughs), Emperor (problemist's usage), and Marquis (from Scirocco, Typhoon, and Jupiter by Adrian King, also used in Töws' generic chess piece creation system, in Derzhanski's list of chess pieces, in the Sweeping Switchers by myself, and in Thronschach by Glenn Overby II)

From playing this on ChessV, I have a few thoughts on strategies.

Firstly, 2 orthogonally adjacent Knights are excellent fortresses, and when combined with 1-2 Lions they can easily hide compound pieces to be brought out later for late game scenarios, where said compound will work well (especially Queens and Cardinals).

Another is that despite speed of getting around the board Wizards are weak, probably the weakest non-pawn piece, since they only have 3 (Ralph Betza ) half-knights, they are quite bad at creating mini-fortresses, and unlike Lions and Knights they are colourbound.

Opening, perhaps after e/f pawn advances, with Wizard to their c/h square is a good idea since it frees a Rook, develops your Wizard, blocks opposing Wizards and protects the opposite central pawn. Also, apparently developing minor pieces first is a good idea.

As often said, sliders are considerably more powerful on larger boards, but Knights seem as strong as / stronger than Bishops in this game.

on another note, funny notation for Wizard is LF, not CF. Funny Notation Camels are L (weirdly, since there isn't a capital C)

This page was locked because of the tournament, but now that it's over, would someone be kind enough to unlock it for me?

The NW piece is called a Grand Horse in Roberto Lavieri's ACHERNAR, a Brigadier in Glenn Overby's veSQuj, and a Mule in Lùotuoqí (Camel Chess). The royal pieces in Jason D. Wittman's Mad Chess move like NF (White) and NW (Black).

'Ostentatious Chess' sounds like a good name for an upcoming submission of mine. ;)

I have tested this game a few times, and I can say it is as good as 
Grand-Chess, although with a different taste. Yes, the game tendence is to
moderately long games, with average of 100-120 moves to finish a good
Opulent Chess game, but it does not demerit the game, the game play is
very interesting, deep, rich and, yes, it is very strategic. I like it.

This game looks to be very strategic; I would venture to say that this game
has about the same strategy/tactics balance as FIDE Chess, while being
richer in both aspects.  The main disadvantage appears to be that this
variant will probably result in longer games than FIDE chess; a blitz game
is probably game/10 or game/15 instead of game/5; a tournament game would
probably take four to six hours instead of two hours.

I especially like Greg Strong's method of coming up with this opening
setup.  Perhaps a similar heuristic can be designed so that a random chess
variant makes for a playable game (the pieces are chosen randomly or
semi-randomly, then the opening setup is chosen at random until we find
one with a good balance).

The KNIGHT in this game is called the Brigadier in Glenn Overby's new variant veSQuj. He writes: 'Under different names, it appears in such games as Way of the Knight, Scirocco, Thronschach, and Lùotuoqí.' The Wild Thoat In Jetan is also the same piece.

A very good (Excellent?) variant of Grand Chess, rich in possibilities, excellent initial set-up and with a smooth game play. I have to test it a few times more, my first experience against Zillions was a very extense game of 140 moves. (Zillions plays it relatively well, but with some ingenuity in position of pieces. Nevertheless, it was a hard-to-win test game)
