Hi Sarah, I believe that you made a mistake on game 4 as Hiarcs lost BIG with -0.76 coming out of the opening and Lost the game! So my point was that it wasn't favorible coming out of the opening for Hiarcs with a negative score because with white choosing the proper lines of play should hardly ever come out of the opening with a negative score to start! And even playing with black the score coming out of the opening should be only a very small plus at must for White and certain lines of play should give black equality with proper play. And the second move 2.Bg5 you say is 1.1% is correct, i over looked this, sorry! In game 1 Hiarcs came out of opening at -0.10 and Lost! " " 4 " " " " " " -0.76 " Lost Big Time! " " 7 " " " " " " -0.21 " Lost! I don't mean to give you a hard time about this as this was not my intention at all, but was just to give you a point of view. I appreciate all the great testing that you perform and are kind enough to share with all of us here. Please keep up the great testing and hope this clears things up. I also like to run tests of the various engines because it is a fun thing to do and really don't care if engine A beats engine B, but i like all the analysis that comes from these games as it gives me some ideas to use in my own games against human opponents.
