This was fast!
What is happening, is GM Benjamin starting to show some fatigue. Or have been the openings?
GM Benjamin is always bad on time and Rybka has plenty of it in the end. Is this a trick not letting him think on Rybka time? Or is it that time management has not been improved and Rybka still wins with much of the time unused? In the future this will give you some elo points, at least on short time controls ;)

Time management has not (yet) been changed, so this is not a deliberate trick, just the old Rybka ways.
With that yet, do you mean that you will work on this feature for Rybka 3?
Or for later versions, if the competence gets closer

I was late and started to kibitz after the 19th move. It didn't look that bad for White I think. Suddenly, a shock... :-)
Appearantly, the problem, or surprise was 23...Nc8 in the variation, which discovers a 3rd attack at the pinned a5 knight. It is easy for us to see now, after the engines have shown it. Although I guess, in 9 from 10 cases (if not more often), a GM will see such a move while considering 20.Rfb1. But nobody is perfect.
After the possible continuation 22.c4 Rda8 23.Qd2 Nc8:

Interesting that you have a computer game with this--I was only able to find four human games, in which the novelty was 11...dxe5, and no computer games...
" A knight on the rim is very dim." 13.Na5? is a dubious move, Ne3 seems more to the point. I would not have played 12.b4 either.
Hi Kurt,
in your game list I see one game where you achieved remis with Black against Rybka 2.3.2a on a Quad. Was this a fair game?

Josef

Hi Josef
This was a (very) fair game. You can replay some further games I have
played vs strong computer programs, most of them under the suspicious
eyes of my chessfriend Rolf Bühler as operator.
http://www.utzingerk.com/man_vs_machine/man_vs_machine.htm
From this experience I can (still) hardly believe why GM's seem to be
unable to achieve more draws. The best try was done by Kramnik, who
unfortunately did at some moments not hesitate to play for a win.
Kind regards
Kurt

Hi Kurt,
Are you the same player who got only 1 out of 4 against humans with average fide rating of 2140 based on the following table?
http://www.fide.com/ratings/tourarc.phtml?codt=26&field1=1317180
If yes then I do not understand how you can lose against these humans.
Did you try to play against them in the same way that you play against chess programs?

Hi Uri
You are right: it's hard to understand at first glance. But I have never played
against humans in the same way that I do against chess programs. When
fighting vs computer programs I know from the very beginning that I have
in principle no chance at all with may normal playing style and this makes
a very big difference in so far as I do not take the slightest risk. And there
is a further important thing to mention: against humans I need usually
much more thinking time and I often get in serious time trouble with then
the corresponding negative consequences. This happens relatively seldom
in games vs computer programs. I have no satisfactory answer why this
is so - it must be something psychological. By the way: some other games
of me vs computer programs can be found under the following address:

I have a quite good score against my Rybka (including many wins) however there are three issues here. Number of CPUs and their speed, opening book and contempt. Despite my successes I must admit that on a faster machine and with unfamiliar openings I would have a VERY hard time. I would be surprised if you could draw as easily as you suggest if you play against Rybka on a fast quadro with a hostile opening book and possible some moderate contempt.
Wow, that sounds quite good; what is your elo or rough playing strength?
EDIT: Never mind--I've found it--2300 :-)
EDIT: Never mind--I've found it--2300 :-)
When I played I had an elo of 2300, but this was ages ago, and when I look at the games I played then, I am shocked about the low quality of many of the games. I think I learned a lot from playing strong programs especially from playing programs like Rybka, though I am not sure how well I would do against humans these days.
Haha, I'm quite the opposite--when I look back at my games from a time when I was around 2200 level or so, I'm shocked that I actually played such games. I'm very sure that I can't now.
Who knows?
Maybe you can be the world champion if you play against humans.
You cannot know if you do not try.
Uri

Uri
Oh no... I have played enough games agaist humans to know that any idea of a serious chess career would not bring enough bread on the table.
Do you have any games against more current engines?
