Re: Stockfish's Asymmetric Evaluations

Thanks again for your valued input, Dann. I didn't realize that SF's contempt factor of 21 merely added 21 to the evaluation. Is that truly how it attempts to avoid draws? If so, then how does that make any sense? After all, since increased contempt is an anti-draw algorithm, then how does increasin...

Re: Stockfish's Asymmetric Evaluations

Hi Dann, Thanks for your reply. You wrote, "If you are analyzing rather than game playing, make sure that you set the contempt to zero. There is a built in offset for the side to move, otherwise." Yes, I'm analyzing in Infinite Analysis, but I don't see how contempt is a factor since Black is given ...

Stockfish's Asymmetric Evaluations

Dear gents, In the last few months, I've perceived numerous examples of asymmetric evaluations from Stockfish. For example, in the following position: r2r2k1/pp2n1b1/2ppqnpp/4p3/1PP1P3/1QNR1PP1/P3BB2/R5K1 w - - 0 21, Stockfish 270618 selects 21 Rad1 after 20 minutes. It evaluates White having a 0.64...

This is Not a Slav Defense

Hi Paul, On a pedantic note, this was not a mainline Slav. In fact it was not even a Slav Defense at all. Instead, this is a mainline Semi-Slav Defense. Specifically it's the ever-popular Anti-Moscow Gambit variation. I noticed your opponents also incorrectly calling this a Slav Defense. That said, ...

Re: Houdini 3, Threads Problem

Hello Stephen, Did you get the pro version or the standard version of Houdini 3? Because I think that the standard version of H3 only allows up to 6 threads. Hi Andrew, Indeed, the Standard version advertisement states, "supports up to 6 cores". Since I have a quad, then 4 cores should be no proble...

Houdini 3, Threads Problem

Dear readers, As a computer dummy, I have the following problem. I just purchased H3 and started an engine match versus Stockfish 2.3.1 at game/35'. After about 40 games, Stockfish held a very large lead. Upon investigation I noticed that H3 was only playing on six virtual threads in my Core i7 quad...

Re: How long until your favorite engine finds f4?

hi stephen -- i read your pieces about your games vs fritz 6 and nimzo 8 some time ago & they were very impressive & a brave undertaking. i believe you brought out the dragon in at least one of those games, possibly more, & may've been punished for it even then...i believe the yugoslav gives white ...

Re: How long until your favorite engine finds f4?

the main idea seems to be whether b3 is too slow or not. i doubt that it is. in most of these kind of sicilian positions white just has a massive advantage imo. a solid najdorf is really the only option for black. if white pushes pawns, develops & castles, as here, it's game over for black. the dra...

Re: Regarding SSDF.

Apologies. I should have spcified non deep Fritz 12. No engine exists with that name. Apparently you mean Fritz 12, as opposed to Deep Fritz 12. Steve From Chessbase: Now Deep Fritz 12 is available for direct download, which means you can get the program very quickly, even if you live in a remote l...
