Eighty-fifth KGS Computer Go Tournament
Sunday August 12th, 2012
These results also appear on an
official KGS page.
|time||4 minutes plus 10/30s|
The first round started at 16:00 UTC.
In the table above,
0 is a loss
1 is a win
J is jigo
left superscript is the player's colour
right superscript is the round in which the game was played
a subscript shows how the result was determined:
R for resignation
T for time
F for forfeit
a number for the points difference after counting.
All the 0s, 1s and Js are links to the game record.
I have nothing to say about the play in this event. Most of the players are much
stronger than me, and I noticed no poor moves.
All of the players played in all of their games, without mishap. I thunk this is
unusual for these events, and I congratulate the programmers.
Pachi's programmer detected a bug, which probably had a serious effect on its play.
He fixed this in time for rounds 22-30.
The 90 games yielded 52 White wins, 32 Black wins, and 6 jigoes. This is
"significant at the 5% level". It helps to convince me that, for 9×9 Go
with Chinese rules, 7 points komi is more appropriate than 7½ points komi
(and 6½ might be better still).
