Re: AlphaZero beats AlphaGo Zero, Stockfish, and Elmo

What better time management, when the match was played at fixed TC? Right. Since they didn't want to bother putting time management in for AlphaZero they may well have felt that allowing Stockfish to utilize its time management would give Stockfish an unfair advantage. This was a research project, ...

Robert H. estimated 9 Elo, as per your link. I think that's close.

Blaming the compiler is simply absurd.
No, the compiler shares the blame.

To reply to the thread title: We are doomed - AlphaGo Zero, learning only from basic rules Sure, humans are doomed, at Chess and Go, and many other things.

Re: Piket vs Smirin 1993 : CB claims 31.Qxd7 is better than

Re: TCEC 10

If Stockfish goes stage 2 lossless I consider it already as winner. No interest to continue with possible K vs H final :!: . Funny that the whole thing pivots for you on a single loss (as the others have). Surely you realize how random that is. No more random than basing the winner on how it did ag...
