But perhaps it's the only way to produce games that Rybka loses against humans:

It's the best score any human ever got against Rybka.

[shiv]

Wanted to quickly point out that given that it is a 45 minute game, the score for the human is quite good. The Fritz vs Kramnik and Deep Junior vs Kasparov were closer to classical time controls (40 moves in 2 hours and 1 hour for the rest of the game).

In a 45 minute game, the computer has a huge practical advantage, as computers rock in time pressure situations. That is why the score in many of these "odds" matches is lopsided in favor of the computer. A pawn does not really matter if you are going to "hang" material in time pressure anyway.

Hence, Dzindzi's performance is really good given the conditions.

But perhaps it's the only way to produce games that Rybka loses against humans:

Yes, thats the point of view from Larry, and it seems unlikely we'll a see match based on normal chess. In a way it's quite understandable, since the odds for the human isn't too good, and still it costs to get a good GM to play.
Thought, I agree with with Wael, from a personal perspective, games I can but into my database is much more interesting, but I believe the future will bring more and more odds-matches when it's human vs comp.

Actually it's not.
I won 7-1 playing as white and Rybka to not have the a-Rook, h-Rook, b-Knight, g-Knight, c-Bishop, f-Bishop, Queen in each game respectively, plus a regular game where i lost.

At the game of Chess of course i don't know what is the best score someone got against Rybka in a match....

Not that you did not play against latest rybka in this match.

I can add that this is the first public match for money against humans that rybka does not win.

Humans lost all previous matchs when winning points mean more money.
It does not mean that the result is better than earlier result and I do not know to compare but the human scored 50% in this match when humans scored less than 50% in previous matches.

[Ovyron]

His point is that this can't be considered chess.
