Re: AlphaZero beats AlphaGo Zero, Stockfish, and Elmo
Posted: Thu Dec 07, 2017 7:50 pm
had a quick look, and it confirms my findings in the Infinity Chess Tourn
earlier this year, where i could beat stockfish sometimes as 'centaur' (using Houdini 4
and Komodo10 on two comps).
Also, the opening book used by Stockfish in this match was weak
if i compare it with my own knowledge as correspondence player (accumulated with
some 25+yrs of experience in computerchess); and not commenting on Tsvetkov's ideas btw.
In line with the analysis as posted on the lichess site, Alfazero didn't
make weak opening moves (although it sometimes could have been better), whereas
Stockfish made such moves as .. Bb7 in Queens Indian instead of the modern ...Ba6 !
(although even then it's not easy (but still possible imho) to equalize.)
But even then, most wins were obtained in the transition between middle game and
endgame, a traditional Komodo monopoly i thought, until now.
Concluding, Alfazero has lots of potential, on stronger comps,
on my comp i prefer Houdini 6 and my own opening book,
combined with some human judgment sometimes and then the
results are still comparable with Alfazero i think.
So bottom-line question is whether Hassabis will continue this chess project,
being interested to find out how perfect chess games will look like.

PS as for the question whether chess is a draw, ask him, i suggest,
about the results of Alfazero playing against itself after days/weeks
of training; he will ofcourse confirm that chess is a draw. (and then
it doesn't matter if you play d4 or e4, although for the time being
d4 and Nf3 give the best practical chances of course; with 1.c4
being a tricky move, if you don't know how to equalize for Black)
