The game on board 4 is a line that is interesting. By playing a line in the symmetrical English reversed one side or the other seems to be saying that a tempo either isn't worth much (black plays a tempo less) or is worth a lot ( white gets to choose the defense he thinks is best with an extra tempo). All very subtle ( unline playing 1...e5 against the english, symmetrical lines aren't anything reversed, they are english lines). I think that Josh may have missed something as I remember a Romanishin game in this line where he played 8.Ng5 e6 9.Nge4 b6 10. Qa4 Bb7 11.Nxd5 exd5 12.Nc3 and won the d5 pawn.
Serper's game will also be interesting as he seems to have gotten a position that folks in San Francisco seem to think is ok if not pretty good for Black. Wait, are we relying on the Mechanics?
Board 2 is interesting as it isn't quite in character for Eric to pitch the 2 B's . Have to watch that one.
