> You can move between boards.

Evidently move between boards but not capture between boards :-( It's extra weird because it's not that the movement isn't projected (e.g. queen blue lines all point correctly across board boundaries just the lines always stop at every piece on the other board, regardless of color)

So, I guess as an exercise in scale, well done! As one million chess boards, caveat gamator

I didn't like the idea of a queen on one board capturing the king on another board as her first move. And then I tried this rule and thought it created really fun counterplay when you're trying to capture a piece someone else is controlling, since you can move to a new board to be safe (and can lay traps this way).

I'm sorry you don't like that decision! But I think that I stand by it.

If you did want to experiment with supporting cross-board captures, an alternate way to address that could be by rotating the board 180° every other row, so that white pieces have other white pieces behind their home rank.

oh this is a pretty fun idea! If I decide to keep this one around for a bit maybe I'll play with doing this after wiping the board

This would be fun!

There exists a player, as of today, who can capture across borders with no apparent in-between cross-color moves or delay.

In particular that means that if you fill the border up to a depth of 2 on one board with pieces, it becomes a theoretically inpenetrable fortress.
