Lc0 just lost in CCC3 to Houdini after +3 evaluation with white. Endgame blunder of course :) .

Re: Alphazero news

Of course Alphazero is stunning achievement! But so far not better than Stockfish only alternative approach. BTW in 22 move loss game A0 is already lost after 12.-Nb6 based my short analysis. May be 12. -Nf8 can still save game?

Re: Home made engine ranking: Critter 1.6a??

Critter 1.6a is basically Houdini 1.5. And Houdini 1.5 is fastest in some testsuites. Doen't mean ANYTHING :) .

90 threads now on CCC 3

CPUs: 2 x Intel Xeon Platinum 8168 @ 2.70 GHz 33 MB L3 Threads: 90 threads with HT on

Is this much faster than TCEC hardware here : 2 x Intel Xeon E5 2699 v4 @ 2.8 GHz Cores: 44 physical?

So far Houdini seems to like HT.

Re: Alphazero news

I only looked so far for TCEC opening games. AO seems to be sometimes like patzer and loses in 22 moves to outdated SF :o .

Re: A tactical crash of Stockfish

I don't remember SF to crash in years. GUIs like Arena and Chessbase crash occasionally, but no SF! But I don't test illegal FENs.

Re: What are the chances of GM Caruana ?

Official (free) webpage was really rock bottom. Small board, blurry, unstable. And analysing engine looks like from 1990 :lol: .
