I see that it is the first time that stockfish lost less than 200 games out of 10000 against stockfish7.

only 185 losses when the previous record was 201 losses of 20170815-0601

I see no details in the page about opening book so I do not know if the opening book is the same and maybe somebody changed the opening book to have more drawing lines.

It would be interesting to see how SugaR would do vs Stockfish 7. I don't know if SugaR is just a developmental version in disguise or if it really is something special.
