I'm posting an idea I have for a 10x8 variant idea, for my study at leisure. The extra piece beyond the FIDE ones in the setup is the Champion piece type from Omega Chess, WAD in Betza notation (Wazir, Alfil and Dabbaba compound piece). I'm thinking of calling this variant idea 'WAD Chess', if I eventually submit it. I wanted to have every pawn in the setup protected, and wound up unawares with a segment of each of Fergus' Gross Chess armies' setups, but on 10x8, for the composition & deployment of each side's army in WAD Chess. Long ago I tried this setup with Waffles (rather than Champions), but found that the problem for players of developing those pieces from that setup (or others I conceived of) would seem to have been irksome. For a 10x8 board I tentatively put P=1; N=3.38; B=3.75; Ch=4.29; R=5.5; Q=10.25 and K's fighting value=3.2; also note that a WAD piece comes close to the average value for all non-pawn pieces in a chess army, IMHO, possibly in itself making WAD Chess a bit more of an interesting extension of chess. Note that it seems a lone WAD and K can always force mate against a lone K on a 10x10 board. Otherwise, rules would be similar to those for Capablanca Chess, e.g. in regard to castling [edit2: using Wide Chess-style castling rules seems to make this idea more palatable, as it would also for a similar 10x8 Waffle/Pheonix Chess idea setup, too).]:

[edit: Backup setup, using chess' castling rules - may be worse than original setup, e.g. if move c- or h-pawn and wish to deploy bishop to 3rd rank, possibly to trade it, or if develop both WAD and knight on one side of the board, rook's pawn there may be unguarded on its original square more often, plus castling rules may leave kings less safe less often, even on kingside, not to mention WADs initially farther from centre - an upside of backup setup is that WADs & Ns/Bs possible initial developing moves never overlap {edit: possible problem: enemy charging b- or i-pawn may make it hard to develop WAD on adjacent file!}:]

[edit: 2nd backup - drawback is it's at the least rather ugly:]

[edit: Below are 2 possible alternate 10x10 setups for the WAD Chess variant idea; pawn rules would now be as in Omega Chess:]

Backup setup idea (it's as for Omega Chess, minus the wizards and off-board corner cell - already a possible drawback):

WAD (Champion):
