That's true but I believe Google purposely choose a weaker version for impact. This is not about chess, this about selling their AI packages to Cities and Governments, the more dominating the result , the bigger the headline - free advertising. Even the result is not as dominating as it sounds - as the relatively high draw rate keeps the ELO difference under 80 ELO, I added one win for SF otherwise Bayeselo does not compute the ELO difference correctly. Current SF would have lost but probably would have been within 30 or 40 ELOUri Blass wrote:Stockfish release a new version every few days that everybody can download and I see no reason to care about the name of the new version.Ras wrote:It's really not Google's fault that the Stockfish team hasn't had enough confidence to release Stockfish 9 for more than a full year.Leo wrote:It is still unsatisfying to use that old of a SF.
Tests show maybe 40 elo advantage for latest version and certainly not 100 elo at long time control so alphago could beat also the new version of stockfish.
