Re: The same as 10 years ago

[/quote]I disagree with the first part as you use your knowledge that you play against a computer. The compute is not using the fact that you can get distracted or get nervous ... that is a difference. About the quote above I can only say that I played 400 games with the weakend Shredder without a l...

Re: Why Knight and (lone) Bishop are so nearly equal in valu

Thanks. I think where you say "centipawns" you mean "elo difference". It appears to me from your data that the effect is much more noticeable with queens off than with queens on, which makes good sense. I think we'll have to try this term again, perhaps modified as indicated by your data. Could you...

Re: The same as 10 years ago

Hi Ingo! You are perfectly right. When playing against an engine without specific conditions the human is enjoying some vantage points - he knows whom he is playing against, while the computer does not, he usually knows the style of the engine, he might resort to some well-tested techniques, he is n...

Some games against Houdini 1.5

Hi, Mel. Here some games against Houdini 1.5 (just because this is the engine I recently have played most games against, but wins against other top engines would come in more or less the same way) Conditions for the games: 4 Core Dell xps laptop 4x1.7 GHz Windows 7 64 bit hyperthreading on or off (I...

The same as 10 years ago

When I played 10 years ago on a Pentium 200 MHz against engines like AnMon and Comet, most of my wins would come by using larger structures of fixed (blocked) pawns. To my surprise, when I play nowadays on a 4 core machine against engines like Houdini and Stockfish, I am still able to win a fair num...

Re: Stockfish 2.3.1 weaker than 2.2.2?

Hi Gary, I think you have made some changes and tested them against 2.2.2, and then tuned the values until 2.3 was clearly superior to 2.2.2. In this case the reasonable thing to do would be to try tuning the changes in respect to a wider range of opponents, the way you did with 2.2.2. The changes m...

Finally downloadable versions of the LittleCompendium files

Hi, During the summer I have done some stuff for the LittleCompendium (my project on chess evaluation). There are 2 new addenda: addendum2 and addendum 3. What might be new. In addendum 2: - a bit on unopposed pawns (that will be a p that does not have enemy counterparts on the same file, while not ...
