I just looked at this position and it looks like a win for black in the
first position. Many Faces evaluates it as a win for black, and plays c1 to
save the lower left black group with almost no thinking time.
Mogo is correct because the lower left black group is not dead.

I think that the original description of the position should have said
'killable' rather than 'dead', and that David missed the fact that
it is White to move.

Please note that pachi1 had a rather embarassing bug of starting the

the playout would start with black as well). pachi2 has this bug fixed;

Are there any current prized computer tournaments or does anyone know
about Ing foundation or anyone else planning to resume the challenge?

Jacques,
Yes, I do an incremental update so the board-size should be almost
irrelevant. I'm not sure why I see any difference between 9x9 and
19x19 but it may have to do with the fact that the edge cuts a lot of
pattern seach short.

I've been thinking a bit about the collection of
patterns from games, whether of professionals or of
programs.
It is possible to get some remarkably high correlation
between the moves played by pros and a predictor - yet
still not have a good program. Why?
One possible answer is that many moves a

Actually, a better way to put this:
King and Pawn positions are generally understand so well by Grandmasters
that they know what the outcome of the game will be once it appears on
the board.
Therefore, at least 1 player is actively trying to avoid this ending,
because the game is essentially ove

Oops, yes you are right. I shouldn't try to look at a position when I'm
half asleep.

The Ing prize stopped when Mr Ing died. He was very interested in computer
go. His foundation still funds many go tournaments, but none for computers.
The current computer go tournaments I know of are:
European go congress (Late July)
US go congress (August, small prize this year)
