Hi, somebody can explain me, what is the value for play R3.?

in this interesting article :

http://chessbase.com/newsdetail.asp?newsid=4837

Report by IM Larry Kaufman

we can read:

Two things to note about this match: First, I set a high contempt value (100) so that Meyer could not easily make a draw if things started to go badly. In general for handicap play I recommend setting contempt at about 2/3 of Rybka’s evaluation of the initial handicap position. Second, I switched around between the three different Rybka versions to maximize variety and to look for any differences. I can’t say that I could tell much difference, but it’s hard to play aggressively when giving pawn and two moves.

OK the question is... ¿ where is the value to change this contempt value ?= example: if I want play versus rybka with a exchange odds (remove rook a1 and knight b8)
or a +knight odd ? how change this value ? on "+" or "-"

Larry say: "... recommend setting contempt at about 2/3 of Rybka’s evaluation of the initial handicap position"

how many time we must permit rybka analisys the initial position ?

and after this ... what we do to configure correctly rybka setup ?

The real question must be:
Is there any value at all of playing these stupid non-chess odd matches :!: :?:

I have a very strange suggestion. How about asking at the Rybka forum ?

Tony

EDIT: I don't want to be unfriendly, but it's about a kind of match that only Rybka can/wants to play, a remark from one of the people from the Rybka developement team, and a Rybka setting.

it is possible that you don't know it, but to train with hadicaps is quite useful for the human player.

you can learn like the program behaves inferior positions before....

it is a way of training.

I find quite more stupid non-chess matchess to 1 minute for game... or 3 minute for game... in those that the analysis depth and ideas don't stop to be a sum of " 30 % style-knowledge & 25 % luck-fortune on ply search & 25 % book chess (that it can never be memorized by a human), and 20 % end tables..."...

it is also quite stupid to give a thousand turns to a list of ELO rating, facing an and another time (thousands of times) to the same programs that are always hunted in the same defects... fattening the elo lists artificially...

bye from spain.
