computer elo vs human elo

What mean Rybka 3 elo 1800 pts  compare to human elo 1800? By my opinion computer elo is about 100-200 points higher if i convert this elo in human elo.

So: 1800 computer elo = 1900-2000 human elo

Why? Becose computers pure mathematic approach - there is no room for psychology and human blunders.

What's yours opinion?

 They're the same, they are fruits. 

yep we are the same, we are  englishmen !

I think every engine has its own unique way to "lower" it's rating from it's highest strength. They are not like human. Their positional understanding is inhuman. Their blunder is inhuman too.

I play stronger with longer time control. My rating against engine is very high. I can draw or even win against engine of super GM level. So, 1800 computer elo = 1900-2000 human elo is wrong imo. Most probably the other way around.

If your engine is Rybka you've done very well then -- the slew of GMs who failed to win in match play at long time controls even with pawn and move odds may want to take a look at your games

ooooh I smell blood

Come now, it's not unheard of... there was that "supranormal" fellow... oh wait... never mind.

If I can string together 5 or so moves against Rybka without dropping the evaluation a ton I feel pretty good... or it's a closed position where we're just repeating moves.

1800 computer elo would be an estimate from results

= 1800 human 

different routes

same place

>:)

So you know that different engine has different limitation then.

And I also read that "Supranatural Activities in Chess". Imo you should not think that there is nothing that other knows that you don't know. That's not a mentality of a knowledgeable person. It will prevent you from knowing many things that you don't know.

If I get you right, I think you forget that engine's maximum ELO is not independent of the hardware specification. You can set an engine ELO to almost anything you want (think of it from software programmer's perspective). If your (human) ELO is 2000, can you play with the strength of 1600? What method will you use?

I'm certainly not much a philosopher, but I do enjoy thinking / talking about epistemology.  The mentality of a knowledgeable person, how to learn things currently unknown etc.  However you changed the subject, we were talking about your wins/draws against computer of super GM strength.  Maybe you could tell me about the conditions you used such as the program, software, time controls, or even the games themselves.  To doubt that you have done something many others who had more skill have failed to do is not denying new knowledge.  To gain knowledge first someone has to filter truth from lies, having a teacher to help is also good... but there I go off on the subject change. So anyway if you have something to teach me about these games of yours go ahead.

Actually I was refferring to the people's responds regarding to the OP's post in the "Supranatural" thread. I don't know if you were one of them or not hehe. There were many good contents in the OP's posts, but people tend to respond with ego, hence see nothing.

If I say that I'm good, without saying that I'm better than somebody, somebody's ego may be hurt, that's a silly fact.

When GMs failed to play against an engine, the engine is probably running in its full strength. Of course you don't need to compare what I can do with what those GMs can. I was not trying to say that I'm as good as those GMs.

First point was, I think human elo of 1800 is stronger than computer elo of 1800. That's from my experience playing against computer and human. My target playing blitz in chess.com is 1900 by the end of this year. If I think playing against human is as easy as against computer, how come I set such a low target when my rating against engines (at 10/0) is a lot higher than that.

Second point was, I think there's something wrong in the software algorithm when the software is "forced" to lower its rating.

Third point, to draw with engine you just need a certain level of endgame skill, plus superior positional understanding (where the engine is weak), and play safely by avoiding tactical complication (where the engine is best at) and swap pieces when the resulting position is "equal".

To win against engine, you need to find chances (combination) to create imbalance, where your positional judgement of the position outperform the engine's "knowledge".

You cannot win against engine if you have a lousy opening knowledge. You should know the mainline and let the engine who first diverts.

BTW, I'm here in chess.com is not playing the way I play against engine. I'm trying to fix my weakness (tactics) and learn certain set of skills. I also believe that I will be stronger if I start to use my creative mind early from the opening stage. I know openings a lot, but when I play here, I don't even notice what opening I have played.

please jusuf, precise which chess engine: it's just amazing to win against someone( it's better somethink) like rybka. And I feel the same think with computers, the weakend ones often playy good moves then blunder and don't realistically change theyr elo.

 actually you were, you said you could beat computer engines at the Super GM level, here's what you said:

I play stronger with longer time control. My rating against engine is very high. I can draw or even win against engine of super GM level. So, 1800 computer elo = 1900-2000 human elo is wrong imo. Most probably the other way around.

Your other comment:

Imo you should not think that there is nothing that other knows that you don't know. That's not a mentality of a knowledgeable person. It will prevent you from knowing many things that you don't know.

this is indeed true, but if it stops swallowing a load of hairy old b....s  like you wrote there then I'll stick with Reb in my ignorance :-)

Chessmaster GME (the weakest I played was Lori, 2210 in my computer) is the weakest, Junior 10 is the next (if not at all faulty). I will try to play against Rybka someday (My friend uses it) and see what I think. Please don't forget that I will not play against it's full strength. Because if I do so, I cannot know the difference between it and Fritz 5 or Fritz 7 or Fritz 12.

I beat engine. The engine's strength is set at 2600 or higher (super GM level). Chessmaster full strength in my computer is 2966 (I don't have to lower the strength because there are personalities with various ratings). Junior 10 full strength in my computer was 3640 or 3460 I don't remember precisely.

computer elo ( 40/40 ) 1800  = human elo 1700-1900

i think computer ELO is lower than the real elo i can win against 1800 PC but my online elo is around 1100
