The appeal for White in this sort of position after 8... e5 9. Bg3 e4 10. Nd2 is that White's pawn storm pretty much has a target on c6, so b4-b5, Qa4 then Nd2-b3-a5 is pretty straightforward, while i struggle to see Black's equivalent plan, since clearly f5-f4 targeting e3 is much harder to get in with the Black knight still on f6.

If all this is true, then we might have to throw away all our opening books! Shocked

QGD: White plays c4-c5

Recently I chanced upon this game:
V.Akobian-A.Almeida National Open Las Vegas 2006.06.16
1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. Bg5 h6 6. Bh4 Nbd7 7. e3 Be7 8. c5
Ne4 9. Nxe4 dxe4 10. Bxe7 Qxe7 11. Nd2 f5 12. Nc4 O-O 13. Nd6 e5 14. Bc4+ Kh7
15. O-O Nf6 16. f3 exf3 17. Qxf3 g6 18. e4 fxe4 19. Nxe4 Bf5 20. Nd6 Nd7 21.
Rae1 Be6 22. Qb3 Bxc4 23. Qxc4 b6 24. b4 bxc5 25. bxc5 Kg7 26. Rxf8 Rxf8 27.
dxe5 Kh7 28. e6 Nf6 29. Rb1 Nd5 30. Rb7 Nc7 31. Qe4 Rg8 32. h3 Rg7 33. Rxc7
Qxc7 34. Ne8 Qa5 35. Nxg7 Qxc5+ 36. Kh1 Kxg7 37. e7 1-0

What was interesting was Akobian's 8. c5. In the 5. Bf4 QGD, 5. Bf4 0-0 6. e3 Nbd7 7. c5 is a legitimate line tried by some strong GMs, but the position of White's bishop on g5 in the Akobian game persuaded Black to play ... Ne4, whereaupon Nxe4 followed and Black's pawns didn't look nice.

Now I seem to remember reading books that say White shouldn't relieve the tension with c4-c5, because Black can play e6-e5, so lets say in the Akobian game Black goes 8... e5 9. Bg3 e4 10. Nd2 and this looks like a type of Chebanenko, presumably Akobian was ready to play this position against a strong opponent, which begs the question: is Black really ok? I guess White will delay castling and just go for a queenside pawn storm, while Black will also delay castling and start shoving his kingside pawns. White's bishop on g3 look splendid as long as it's not a target for Black's pawns.
In any case there will be no draw for sure!

Any thoughts?  Smiley
