Stockfish Results: Don't Understand_Can't Begin To Explain!

Post by geots »

Let me be very clear. I cannot explain these results, and they have happened repeatedly over the course of time. No way is this anywhere near the first comparison. But I can for sure tell you that it has absolutely little or nothing to do with the compiles. The speeds are fairly close, plus when it comes to compiling- Jim_Ablett_has_no_peers! So that is not the place to look. Anyway, this is not one of those results "that just happens" from time to time. As I said, I have no answer.

In the 2nd match- Stockfish is "version 300413", by Ipman/Jean-Paul. And he has done a good job with it. It is the version that scored 57% ag. Critter 1.6a and 48% ag. Houdini 3 in TomCass' 6-core testing. He obviously has some insight that even Marco and Gary cannot match.

Lastly, the difference is usually slightly larger than this one- and you don't get that from simple param changes.

Hi George,

Shouldn't you know by now that 100 games is like a lottery?

Yes, if I had not run exactly 23 other 100 game matches with them ag. other common opponents, and repeated some of these 2 and 3 times. 50 elo is actually as close as it has been.


Best,
