Yes, I'm not a fan of the CGA graphics at all. I blundered in my first game because I misinterpreted the piece graphics.

I think https://nanochess.org/archive/tiny_chess_1.html is that, possibly for an older/newer version of the engine (found via https://nanochess.org/chess4.html#sour, which SatvikBeri mentioned in a different message)

Still looks a bit weird on my iPad (huge black pawns), but easier to beat because it’s easier to see the board.

This is the same engine but doesn't look quite as far ahead https://nanochess.org/archive/tiny_chess_2.html
