As far as I read the paper, I didn't see a book for Stockfish mentioned, so I guess, match was bookless.

Considering that, opening isn't that bad (as described in document, AlphaZero anyhow has "reinvented" most opening moves often played by humans already ).
But 8.Qe1 from SF seems a llttle exotic anyway, doesn't it

[Jouni]

Sounds like april fool. But isn't !. I just read, that they are not interested in chess? But I read somewhere: So basically they played 400 cores engine vs 60 cores engine. Hmm..

[smatovic]

So basically they played 400 cores engine vs 60 cores engine. Hmm..

From the paper:

Code: Select all

AlphaZero and the previous AlphaGo Zero used a single machine with 4 TPUs

I guess it depends on how you count the TPUs
