No, I had several plans anyway, accounting for several of your different options, so you would have only delayed checkmate by a few turns, unless you had done something unexpected.
I kind of want to work up through the larger variants, beginning with Heian Dai Shogi, then moving on to Dai Shogi, Tenjiku Shogi, Dai-Dai Shogi, Maka-Dai-Dai Shogi, and finishing with Tai Shogi.
It could take a while to play them all, and I know you're less of a fan of the long and big game than I am, so if you don't want to do that, that's OK with me too. We don't have to play them all, either, unless you want to (which would be great ;)). We can also alternate between large and small variants if you wish.
If someone wants to play a three player game, I'd be OK with playing simultaneous games, or taking a break from the large variant to play that.
