Got home, move stuff around and finally got to the match. Here is how it looks right now...
Bd. 1 Nakamura played 1.b3, Kachieshvilli played d5 and c5 to which Naka went for the Nimzovich attack (instead of a Bird), Kachi played Nf6 and g6 to get a reversed Queens Indian and Naka played Bb2xf6 doubling the f pawns. From that point, the position officially became.. a mess. Naka plays for activity, takes an isolated e-pawn and advances q-side majority. Maybe a little better for White.
Bd. 2 is still in the opening, a Kan Sicilian (Serper fav) with 4.Bd3. Charbonneau has set up a Maroczy. There are good a bad to this for Serper, good that he isn't already way behind on time, bad that his past results in the USCL from this formation aren't the greatest. little better for White
Bd. 3 Another still in the opening. Symmetrical English, Lee opted for the Botvinnik formation and Bonin countered with an interesting sequence of b6 and Bb7, then fianchetto the other side. This is about the sort of thing I had expected and will tell how mature Michael has become, or possibly how mature Bonin already is!
Bd. 4 QP game with 3.g3. Chen opted for a London setup, exchanged Q's on b3 and Bf5 x Nb1. On the face of it this appears equal, but either side has trumps to play with and could turn matters.
Back in a bit
Bd. 1 has changed. White squared B's got exchanged on e6 and Black recaptured with a Rook, then doubled on the e-file aiming at the e3 pawn. Naka is getting the Q-side pawns revved up to go further and kind of defending e3 by observing a Re8 with his Qa4, so if Rxe3 the Qxe8+ will pick up 2 Rooks for the lady. I don't think it will go that way though.
On Bd. 2 the players are still marking out their fighting zone. In other words, no real contact between armies. This is fairly normal in the hedgehog.
Down to board 3 we find that Lee has advanced b2-b4. I think this is good for White because Bonin threw the move a6 in and so an exchange b4xc5 will present an issue for Black... if d6xc5 then b6 is being observed by Rb1 and has no pawn support on a7, while b6xc5 loses the Bb7.
Board 4 has changed a bunch. Chen castled long, Sturt arranged f3, e4 and then e5. This is good for White as Black's counterplay is far off. I feel kind of odd saying that, but here is the point. Black can create some play by g7-g5 , Bf8-h6 and Rg8, but that all takes a bunch of time and at the end White might just take the g-file and be happy. It is because of the White space advantage.
