Apparently 15 isn't the right move number for Nd5.



Thanks for the reply. I should have said 16.Nd5. This is Winants-Adly 2012:

1. d4 Nf6 2. c4 e6 3. Nc3 d5 4. Bg5 c6 5. e3 Nbd7 6. cxd5 exd5 7. Bd3 Be7 8.Nge2 O-O 9. Qc2 Re8 10. O-O Nf8 11. f3 Ng6 12. e4 dxe4 13. fxe4 Ng4 14. Bxe7 Qxe7 15. Rf3 c5 16. h3

After 16. Nd5 Qd6 17. Rg3 cxd4 18. Qc7 Qf8 19. Nxd4 it looks like white's pieces are more aggressive but black has e5.

I notice that back in 2004 ECO gave (12. e4 de 13. fe Be6) 14. Rad1 as dubious, and had 12. Rad1 Be6 as leading to "unclear."


If 12.Rad1 it looks like to me that after 12..h6 13.Bxf6 Bxf6 14. Bxg6 fxg6 15.e4 Bg5 white has no advantage.

12...Be6 is played about 10 times more often than 12...h6 but whether it is better is another question. It seems to me that in Kasparov-Barua black did not play the best moves (see original post)

Schandorff Playing 1.d5 The Queens Gambit page 28-29
1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. cxd5 exd5 5. Bg5 c6 6. Qc2 Be7 7. e3 Nbd7 8.Bd3 O-O 9. Nge2 Re8 10. O-O Nf8 11. f3 Ng6.
Schandorff writes: "You should sit on your hands and keep saying 'prophylaxis' to yourself. 12.e4 is premature as black answers 12...dxe4 13.fxe4 Be6 14. Rad1 Ng4! with counterplay."
It looks like this is OK for black but it leads to a near equal position with white posted a little more aggressively. In Winants-Adly 2012 (the same year the book was published) black won a game in this line but white should have played 15.Nd5 hitting the queen.
Instead Schandorff recommends 12.Rad1 and shows Kasparov winning in this line on the internet, as white, but, not mentioned in Schandorff, after 12..h6 13.Bxf6 Bxf6 14. Bxg6 fxg6 15.e4, in Granara Barreto-Vyzharov internet 2009 (1/2-1/2), instead of 15...g5 black played the better move 15...Bg5 with (my opinion) equality.
Schandorff also gives the bishop sacrifice 13.Bxh6 "leading to a promising position." I'm not sure whether this is good for white, black, or neither.
