- A bug in the MC policy (wrong distribution, rotated, etc)
- A bug in the scoring function/branch update
Since your bot can play 9x9 I guess it's the second. Ofc it's easy to know the winner, but if by any chance the information is reverted in the branch update the bot will try to play as bad as possible.
You can even test this with the original code. Instead of returning the final score, simply return the first player who captured in the game.

Hi, toying with Don Dailey's old reference bot (pure monte carlo). Trying to make it play Atari Go,
it plays decent regular Go on a 9x9 but not well at all when trying to make it play Atari Go. I try ending each playout as soon as a capture is made and score the moves with amaf. This leads to almost random play even with a big number of playouts. Anyone tried making a Atari Go monte carlo player, anything obvious I am missing?
Regards Andreas
