Bugs were fixed, redundant code was removed (for example queen contact mate detection in eval is gone!), many things were reorganized, the executables are noticable faster now. From what I've seen so far, I'm very happy with the 1.8 release. Good work! Germany vs. Argentina was ok, but most of the time I prefered to look at the 1.8 sources. :lol:
A 20 Elo improvement at the top is quite substantial, you guys have some unrealistic expectations. Congrats to the Stockfish team for continuing to improve their great engine!
And Germany was awesome this afternoon, made Argentina look like a very poor team (like England) ;).

I think the real Elo race has not yet begun.
The acutal 1.8 source code is a great base for further improvements.

Howdy, Nice to see Stockfish development. I do not understand the meaning of the variable tables. It appears that testing is done @ 32 bits. Does 64 bit stockfish exist ? Thank you

Nice. Private settings of a free engine. Not that I believe in these setting wizardries.
They will be released in due time. I do not intend to keep them private forever, just until I get everything the way I want it.

This is simply impossible. Check your Bayeselo or whatever you are using...
And 1/52 is also wrong. It's a two-tailed test so it cannot be 2.5% for 2 sigma, but only 5%.
In your case it's actually 1 sigma instead of 2 (+/-10 elo for 650 games).
