AlphaZero Stat playing Stockfish 8
"The updated AlphaZero crushed Stockfish 8 in a new 1,000-game match, scoring +155 -6 =839."
AlphaZero 80K nps
Stockfish 8 70M nps
This was win percentage of 57.5% (+53 elo) for AlphaZero over Stockfish 8. And Stockfish 8 played without table bases.
For this match my system runs about 1/2 the speed. A little less then half for Lc0 nps, and a little more then half speed for Stockfish 8 nps, but Stockfish has TB's.
Leela Ration is 1.14.

First update, I plan on playing 100 games. If AlphaZero was crushing Stockfish 8. Then Lc0 is obliterating Stockfish 8 in the first 20 games.
This is the first test for the NN 42845. And it looks to be one of the better NN so far.

But Lc0 is winning at a much higher rate, regardless of the losses.
Lc0's win percentage is 64.52% (+104 elo)
AlphaZero's win percentage is 57.5% (+53 elo)
