Thanks Ingo! Will be very interesting to see how some of the eval changes play out against a wider set of opponents.

Hmm, last minute changes have apparently made engine worse than 2.2.2

Re: Stockfish 2.3.1 running for the IPON
I'm pretty sure that SF 2.3.1 is not actually worse than 2.2.2, and if it finishes lower on the IPON list it will probably just be due to margin-of-error. Still, we see the same thing happening that happened with Critter and with Houdini 2.0, namely that newer versions look like big improvements in ultra-fast testing but the gains disappear once you get beyond blitz levels. Some diminution of gains with longer time limits is normal due to increased draws, we get that with Komodo, but when the gains disappear (or nearly so) with depth it indicates that the changes did not scale well. Finding improvements that help at any level is the challenge.

Is that a petitition and if so where can I sign it?lkaufman wrote:Finding improvements that help at any level is the challenge.
I believe that the ultra fast engine testing with tousands of games reaches a border line for "normal" chess when it comes to elo improvements which should be visible for humans!
Maybe we need a change (or extension) in paradigma of engine development as we had it a few years ago with the change from knowledge to search ... maybe the pendulum is swining back ...
Ok, implementing knowledge is more difficult than "speeding up" the search or cutting the tree but I would find that very interesting!

Edit: "implementing knowledge is more difficult than "speeding up" the search" is easy to say ... no offence ment, I know that this is difficult enough!
