@ H.G.: I'm not 100% clear on whether champion+K cannot always force mate on a 12x8 board (which might be called bigger than 10x10 due to the greater width, though 10x10 has more squares in total). Might you happen to know?
Also, I noticed on the Omega Chess commercial page somewhere that champion+K cannot [always] force mate in that variant, but no doubt that's because of the 4 extra squares added to the board edges, at the corners. It's also noted there, as I long ago figured out, that R+K cannot always force mate, either, though it's often possible I suppose.
