Seems like 60b KataGo with a lot of playouts thinks it's a draw

One such sequence is something like this, it doesn't mean it doesn't have blind spots or alternate sequences, but this is a ton of playouts. Basically the correct komi for Japanese seems to be 6 on 9x9 boards

I did 3-4 and there are a lot of draws

but a lot of moves are not obviously incorrect (but after playing it leads to a loss), so the amount of variations in 3-4 is staggering

For tengen it only likes really two sequences, but that just means it can't see the unlikely draws

For 5-3 there's an ogeima variation, and a jump variation

because there's less symmetry I investigated the ogeima one first, and it seems once you establish the two white groups the game goes directly to the endgame
