 | | Boomie: <kwid: It seems that we need to play instead of c3 < 7.Nbd2 >> The knight almost always goes to d2 so playing it at move 7 doesn't help GMVA plan. There is no obvious reason to play c3 at move 7 and it helps our opponent focus his planning. It seems like a bad move to me for that reason. |

Is this our best line?
5. Be2 <Ne7 6. O-O c5> 7. c4...> I'm hoping not...heh.
Curiously, here 7. c3 is thematic, defending the pawn chain.
click for larger viewThis position feels right to me. Black has taken two moves to make c5. That has to be good for us. The question is what can we do with our lead in development? Over the board, 7...Nd7 has been played most often Opening Explorer. After 7...Nd7, the Perfect15 opening book has 8. Nh4 as most often played (39 games) with 9. dxc5 and 9. Na3 deserving attention. All these lines scored well for white in engine matches. |

| Aug-17-12 | | Ovy: Well, c3 is not a bad move. It just seems to lead to positions which we should like, as there is a lot of positional fight in such games. I think 7. ..c5 is not challenging, because: 1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 Nd7 6. O-O Ne7 7. c3 c5 8. Be3 Nc6 9. Nbd2 Be7 10. dxc5 Nxc5 11. Nb3 
click for larger view is nice for us. More challenging is 7. ..h6. The most common answer in my database is Na3, and a4 doesn't appear in any (!) game. It is the point, in which we can run away from the theory and shake our opponent. The problem is that there are many sound answers to this move: Qc7, c5, a6, Rc8, maybe Ng6, and all of them need analysis. The line suggested earlier, with 8. ..a6 9.Be3 Bh7 10.a5 Nf5, is probable, and 11.c4 allowing opening the centre and weakening our position is not proper. The point is, we should find better move in this place. My first thought was 11.b4, and I will analyse this position tomorrow or on Sunday (maybe I will find another move).
