Although it was nice result for McB , statically it means very little , simply not enough games and it could be considered a lucky run. My main objective is with McBrain is make it interesting and useful programs while trying to keep the playing great strength of Dev Stockfish. Years ago , except for Crafty most of the top engines were not open source ( yes, Crafty at one time was one of the top engines and the strongest open source engine ) and now we have the strongest engine in the world being developed by many contributors as well as many volunteers who are contributing CPU time. I am personally very grateful for that and my little effort here is simply to pay it forward to other computer chess and chess enthusiasts. I hope some of you find McBrain useful.
