The last tries in this line were:



13.Nxb6 and then 14.0-0



13...Nbd5 is the new move here.

So if you're looking for improvements, you obviously have to analyze these moves.  Wink

1.Nf3 d5 2.d4 Nf6 3.c4 e6 4.Nc3 Be7 5.Bf4 O-O 6.e3 Nbd7 7.Qc2 c5 8.Rd1 Qa5 9.Nd2 cxd4 10.exd4 dxc4 11.Nxc4 Qd8 12.Bd3 Nb6 13.O-O Bd7 14.Nxb6 Qxb6 15.d5 Rfd8 is one of the main lines where Black looks very solid. 16 Qe2, Rac8 was Nepo..-Aronian, 2011 draw in 85 moves.
Has anyone seen improvements for either side in the first 16 moves?

Hm, well yes, looking at the exchange is not exactly the path I want to take as Black. I guess that's reason enough for 5...0-0 and the queen's knight to d7.

Thanks!

I had the same thought -- e.g., ...Nxd5 isn't available in the first two comparable cases I thought of:  1. d4 d5 2. c4 e6 3. Nc3 a6 and 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 0-0 6. Nf3 Nbd7 7. Rc1 a6.

Speaking of old books, I noticed that while NCO and ECO both unsurprisingly enough had 5...a6 as leading to +=, they seemed to differ as to whether White should play 6. c5 or 6. e3.

Except Black would reply to cxd5 with ...Nxd5 here, not that I'm saying its not a good idea for White, but suspect he has better options. 6.c5!? going for the old, what do you call it bind might be one idea. Numerous ways to play after 5...a6 for both sides of course. If I managed to dig up my old Colin Crouch book he might have something enlightening to say.

By the way with 5...0-0 and 6...Nbd7 holding up so well for Black these days I dont really see the need to look for anything esoteric against Bf4, but each to his own.

Most of the time that Black plays an early ...a6 in the QGD White will try to "punish" this by playing cxd5, transposing to an Exchange Variation where ...a6 is supposed to be useless.


Exactly. It applies here, I think.

In the never-ending quest for something in the 5 Bf4 lines I haven't seen much on 5...a6. It looks like a good move to me, but my analysis powers are not equal to many on the forum. Nor have I found discussion about it. Is there any merit to this move?

I suppose I should add that I am looking at continuations with 6...dxc4 (7 Bxc4 b5) with ...Nd7 and ...Bb7 to follow.  Huh

I assume that you are talking about 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nf3 Be7 5. Bf5 ... ?
What else have you tried against 5. Bf4? I think nowadays 5...O-O 6. e3 c5 is supposed to be critical, however I don't think there is anything wrong with 5...O-O 6. e3 c5. I don't think there's something terribly wrong with 5...a6 either but it looks too slow for my taste. However, I haven't really investigated on this line. The main merit of it seems to be that it stops Nb5 but this isn't really a terrible thread. Why are you dissatisfied with the more theoretical options?

Edit: The original Post didn't make much sense before the edit because i got the moves wrong.
