yes, but still, the 0th rank will be key for promotion
Fast infinite sandbox game #1 (sign ups open)

I was tanking the king though, the square it was captured on is further back. Isn't it supposed to respawn where it died?
Ah. Had not considered that. You are correct.

Events:
until end of the game "Toroidal Universe" The board basically becomes a huge torus (or sphere), not infinite, but can expand infinitely to account for anyone's huge moves. If you make a huge move you can either decide for the torus to expand to fit your move, or you can choose for it to not and you just continue to slide and wrap around the board until you appear on the other side on the same rank/file/diagonal!
Until the end blitz : Capturing pieces yields 100% of their point-worth! But pawns + pillars are not allowed to step forward for the duration to halt promotions. (They will still be allowed to defend pieces)
Pieces that can be captured (with no risk of dodging) have the black triangles in the corners. Piece movements are now visible if off the board. Pieces that have just been dropped have a shape around them too.
Given the toroidal universe this cannot be 100% ensured. It's up to each player to think of the consequences of this event and if I don't put a capturable sign when there should be one do mention it when capturing it. I will not be trying to see what captures are possible.
You could claim an area of 20 files or so, then other people can't claim it.
It would also provide more variety at the beginning rather than just pawn racing
