Pachi has won the game, but so did Robert - I was the one who lost.
The game was 2 handicap stones and 4.5 komi for white, and it turns
out one must be extremely careful when using gogui in that scenario,
since when handicap is set, komi is _zeroed_, even when set explicitly
before.
So, Pachi was playing as if the komi was zero all the time. Normally,
I would notice during the game based on Pachi's output, but Robert
requested the screen to be visible to him so I turned off the GTP
shell...
On board, we counted 1.5 win for white. I have verified that with 4.5
komi, Pachi would play F3 instead of D13 and win. Tough luck. :)
