My first impression of watching the game was that Leela was

ahead for the first few moves that is was playing arbitrarily.
I was blasted for making that observation many months ago concerning
the
possibility of handicap matches on CGOS. I thought it not a good
idea
for Monte Carlo players because each player starting with a dead won
or
dead lost game. The response was that it didn't matter, the programs
would still fight.
I wonder if this was part of the beginning move selection of Mogo in the
games against Mr Kim. Can anyone on that team check their logs and
respond?
It could turn out that the best strategy is simply to let the opponent
play desperately and not over-react, because to have any chance when
giving 9 stones you must in some sense over-play it.
This exact point was made in the post game analysis by Mr Kim. He
explained
that he expected about 1 dan replies to his approach in the lower
right, and
thus played to live in the corner and have an extension across the
bottom.
An observer said "Oh, so you made an overplay." Mr Kim replied "I have
to
overplay (against 9 stones)." He later showed how he would have played
it had
he expected mogo to find what he called 4 or 5 dan moves. He also said
that
he was impressed with Mogo's ability to avoid overreacting, that it
could not
be provoked like a human once it was ahead.
Mr Kim also said that from his perspective his opponent in the last 2
games
felt completely different than in the first 2 games. The difference,
of course,
was the additional search time. In the 2nd game mogo played the first
half
thinking it had 10 minutes, even though the KGS clock was set to 15, and
mid-game the operator realized the mistake, took it offline and fixed
the
clock before reconnecting. But it was too late, so Mr Kim, other than
being
confused by the opponent abandoning and reappearing, did not get much
chance to see the difference in play.
Cheers,
David
