KataGo games on non-square boards

In the ongoing KataGo distributed training run, all sorts of different board sizes are used for training games, including non-square boards! I think it’s really interesting to see superhuman play on these strange boards, so I thought it would be nice to have a thread for sharing and discussing them.

This 19x14 game starts from a somewhat familiar opening:

19x9 is a nice size since it combines the most popular square board sizes :blush:


These two 7x19 games start with the same 5 moves, but then diverge into very different outcomes:

Can KataGo train on irrectangular or lacunar boards, though?

(eg. the one in Semi-random starting position + flexible komi)
