Do you or anyone have more info on this match? Time controls,computer speed?
Also does someone have these games converted to PGN. I was not able to play over
the games as posted on the FIDE site (I'm way too lazy to punch in the moves
manually).

Yes, the sample size indeed matters as you have pointed out. Otherwise we
would always question the last place finisher of GM tournaments. Didn't Shirov
play about 300 ELO points below his rating in a recent tournament?

That computers have of no knowledge of who they are playing and therefore cannot
prepare for an opponent is not so much unfair as it is a weakness of the
computer program. But this same weakness can be a strength in that it allows
the machine to "play the board".

The average GM ELO is around 2540 (Kotronias is 2555). I believe the top
commercials are around 2500 ELO. I base this on the quality of the games
I observe them play. In playing over the games from CCL it is becoming harder
to distingush from playing over tournament games of players rated in the
2450-2550 range. Of course computers still make blunders but these are
frequently found in the low to mid GM's also.(Super GM's too for that matter).

I also base this assessment of 2500 computer play on testimony of strong
players. Lev Alburt and Larry Kaufman both say around 2500. Most recently
the interview of Anand was revealing. Here is part of that interview taken
from the FIDE homepage:

Q: You had an easy time against Fritz. Does the play of Fritz
fall into a predictable pattern for you?

A: It is very tricky. I mean, when I play it on my machine here, it sounds like
a see-saw. When I am concentrating I usually do very well. Sometimes you usually
feel you crush the machine. You  think around and the next thing you are not
going to win. If you play a 100 games I tell you you go through a whole gamut of
chess emotions. I will be piece up. I will be simplifying into a won ending. I
finally find myself that I have missed something silly. There are certain things
you can stop doing. When you play the queen's gambit declined you wait for
something to happen on the king side. You don't have to worry about the moves
which say Vladi (Kramnik) found in the first tie-break game. It may or may not
find these things. You can stop running out of a problem but suddenly other
problems start running larger. Specifically it is tactics. Against humans you
often forget about a pawn. It doesn't matter. You think top players punish every
inaccuracy. It is not so. Certainly some inaccuracies are punished ruthlessly,
others are not. Especially if the refutation is not so easy to see. Against the
machine it is totally different. Of course what I did against the machine was
perfect. If I am able to come up with a long term plan and get these positions
it is very smooth. I find it quite a challenge playing it. I enjoy it. I get a
lot of satisfaction. I was very very pleased. If you have managed to outplay the
computer, you get pleasure. It is like tricking somebody. In the same way I will
be very proud if my opponent had prepared a certain line and I use a
transposition to trick him out of it. I get the satisfaction if I get the
position I want to play against the computer.

Q: You were worried about one plan of the computer?

A: At a certain point I was debating whether I should play this move g5 or not.
Normally it was better to play h5 and fight for the light squares very
vigorously. Here, I felt if Fritz got f4
and g4 at a certain point my concentration would wane. I had to watch for this
f5 trick and tactics every move. To cut a long story short I wasn't worried
Fritzy will find the whole plan. Only if it stumbles on Nd3 and then the only
obvious square to go is f2 and then go to either e4 or g4 and land on f6. To
play Nd3 it has to see the whole plan otherwise it wouldn't do it in the first
place. Well, during a game you have all sorts of fears and some of them are
revealed and also threatening.

Q: You made it look easy. What will be the result if Fritz played
using a mainframe?

A: After beating it it is easy to say. Okay, everyone saw the press conference
before the match and I was tense about it. The computers are getting to a point
where you have to be very
careful. Fully concentrated. And then go from there. When I play Vladimir also I
am concentrating well and so on. But when I play against the computer I don't
have this tension. I know if I get the right kind of position I win. If you get
a tactical position, you have to concentrate fully. It is anyway superior to you
in tactics. It is not if you concentrate you are equal. You are not. So it is
weird. Also, somebody tells me it is six 333 MHz processors all running in
parallel. I have no way to translate that into chess moves. All I know is it
sounds frightening. So
far I feel I am quite confident when I am playing computers. The danger is
always there. I think if I play twenty games I might not do that well. If I do
play that many I am not going to be that concentrated. Days are long long gone
that you can laugh at this machine.They are capable of beating anyone because of
a) they don't know who you are and b) they are overwhelmingly superior to all
humans in certain categories and c) inferior in minor categories.

Anand does not say directly what Fritz is rated but his words are very
interesting. Note the comments..

Does Anand talk this way about IM's too? Sounds to me as if he thinks computers
are pretty strong.
