Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

Interesting among those positions are the following imbalanced wood counts: >> ** IMBALANCED ** << [+111]:( r1bq1rk1/4bppp/p1p5/1p1nR3/8/1BP5/PP1P1PPP/RNBQ2K1 w - - ) >> ** IMBALANCED ** << [+111]:( r1bq1rk1/pp1nbppp/4pn2/2pP2B1/3P4/2N1PN2/PPQ2PPP/R3KB1R b KQ - ) >> ** IMBALANCED ** << [+111]:( r1bq...

Here is a sample of 250 opening exit points that fit the criteria I described (bigger collections exceeded 60K bytes): rn1qkb1r/pbp2ppp/1p2p3/3n4/3P4/P1N2N2/1P2PPPP/R1BQKB1R w KQkq - acd 59; ce 9; white_wins 6004; black_wins 5124; draws 5031; Opening Queen's Indian Defense: Kasparov-Petrosian Variat...

Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

Excluding certain lines of play best on artificial criteria can be unfair to those engines that do play those openings much better than others. For example, take Stockfish and the Black side of the King's Indian, which SF handles better than most. Would you exclude that from testing at Stockfish's ...

Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

I have seen opening books with checkmate end points used in Elo measuring events. So, is "down a queen" acceptable? If not, isn't it an arbitrary value just like any other? Down a pawn is "pawn odds". If you were an engine author, would you like to fall out of book down a pawn? Komodo, Houdini, Stoc...

Some recent positions analyzed

Most of these were given without best moves or scores. I would be interested to know which are correct and what the expected scores are: q7/6pk/P2R1p2/4p2p/1B6/8/PNP4r/1KR5 b - - acd 48; acs 4560; bm h4; c0 "h4 and Rh3 are permutations. I do not think either move can hold the draw"; ce -243; pm h4; ...

Re: Stockfish wins CCC 3: Stage 1 only after last 60th game

I find even during the match, the only way to see/download games is to look at the crosstable and select them from there. Seems not optimal. Another comment (and I do appreciate the tourney): the openings are sometimes quite unbalanced. I understand that seeing a whole series of draws is something ...

Re: Shadow Walker 4CPU

Interesting that the leader is jumping around like mad, but Arasan remains nailed to spot number 2.

TCEC 14 - what happened to the final?

I was watching a while back and a lot of v14 finals games were played.
Now, TCEC seems to have moved on to TCEC Cup 2 but there are no games stored for download for the TCEC 14 finals.
What happened?

Re: A new Unbreakable from Neghina...

Well, Cfish-dev also finds Na5, albeit with a score of 0.00. But I doubt it can solve the study. Sting's PV seems odd to me. Qh6? Well, the study is called "The Confusion" It seems to toss the queen, but subsequent exchanges make most of it back. No idea why it was chosen, but it thought for an age...

Re: AMD's New RX Radeon VII - NVIDIA RTX 2080 Killer?

So i think it is AMDs turn to release some optimized OpenCL NN libraries and add TensorCores, or a similar technique, to their gpus. -- Srdja Here is a NN lib for OpenCL: https://github.com/hughperkins/DeepCL I've no idea how good it is.
