Tafl,

I am glad you had a look at that line.  I had been working on that line and in the early morning on Saturday, before I left to my indoor soccer game, I was inspired to do the maneuver with the Queen (Qe8...) and decided to work the plan or to see if it was workable.  I have looked at many branches and Black looks good.

GM Prie,
Have you had a look at the line Tafl and I are discussing?  I think this is a rather unique idea for Black against the variation posted by Tafle vs ....Nh5.

Any ideas would be truly welcome.

His 3...Nc6 recommendation is interesting. There is however something strange after 4.Nc3 cxd4 5.exd5 dxc3 6.dxc6 Qxd1+ 7.Rxd1 when he says that 7...dxc6, which is illegal, is equal. I assume he means the natural 7...bxc6, but then a word or two about Johnsen/Kovacevic' 8.Bc7!? would have been helpful.


I had intended to reply to you Tafl to say that the answer was already planned in the original 3.Nc3 Zichichi's game of December's update but the whole Forum diseappered then!
Hope it satisfied your expectations...

Next february's update will finish with the subject including an exhaustive review of the book. Do not miss it!
It is absolutely essential for the Londoner ( against 1...d5!) to hear both sides of the story!

Yes, I am still interested.

But I have two dead-lines approaching that will take most of my time until Monday. So I need some time to conclude my analysis. So far I can only say this:

1) I am still looking at 14.Qf3, but 14...Qe8 is a surprisingly strong move. If Black can coordinate his forces before White's kingside pawns become too strong and can do so without exchanging too many pieces, he will normally have the better chances. Not so much because of the material situation but because White has trouble finding a safe place for his king.

2) I may have to backtrack and look at other 14th moves or even go back to the position after 9...g6, and try the safe 10.Ndf3. But I will do so reluctantly as that would to some extent admit that 9...g6 is a valid try.

The problem with 14.Qf3 is 14... Qe8, when Black will place his Queen on g6 and it takes a commanding position.  If White decides to place his king on the Q side with 0-0-0 Black has a ready attack with ...Bd7 ....b5-b4 ....Rc8  and the Qg6 takes a fantastic diagonal to White's King, and the Nc6 can play Nb4 or Na5. 

So what do you suggest will save White or, if you still think White is better than this, what do you suggest is a good way for white to proceed?  I am eager to know.

@BladezII

I must quote Bent Larsen: Long analysis - wrong analysis (no offense intended)

After 1.d4 d5 2.Bf4 Nf6 3.e3 e6 4.Nf3 c5 5.c3 Nc6 6.Nbd2 Bd6 7.Bg3 0-0 8.Bd3 Nh5 9.Ne5 g6 10.f4 f6 11.Bxg6 hxg6 12.Nxg6 Ng7 13.Nxf8 Bxf8, I agree that White's correct plan should be to push his h-pawn. But I would like to develop a little first, so I prefer 14.Qf3.

Then, of course, Black has many options. But natural attempts to develop and break the centre open seem to fail, e.g. 14...cxd4 15.exd4 Qb6 16.Rb1 Bd7 (16...Nf5!?) 17.h4 Re8 18.h5 e5 19.fxe5 fxe5 20.0-0 Bf5 (20...Be6 21.h6 Nf5 22.Qh5+-) 21.h6+-.

This obviously is only a sample line. At some point you simply have to break it off and evaluate instead of calculating further. But I am eager to see your improvement after 14.Qf3.

@ Tafl

I have looked at option C) for some time--

Here is what I have and it was nice to see that we coincided in one of the lines and I will post it.  I have explored other options for White as well which are not as risky as the one you took, but which still tries to push for an edge.



1. d4 d5
2. Nf3 e6
3. Bf4 c5
4. c3 Nc6
5. e3 Bd6
6. Bg3  Nf6
7. Nbd2 O-O
8. Bd3 Nh5
9. Ne5 g6
10. f4 f6
11. Bxg6

(11. Nxg6 hxg6 12. Bxg6 Ng7 13. Bf2 e5 {Black exposes White's King by opening up the center.})

11... hxg6
12. Nxg6 Ng7
13. Nxf8 Bxf8
14. h4

(14. Qe2 cxd4 15. exd4 Qe8 16. h4 Qh5 17. Qxh5 Nxh5 18.Bh2 Bd6 19. Rf1 f5 20. Ke2 b6 21. Ke3 Ba6)

14... Qb6
15. h5 Qxb2
16. Rc1 Kh7
17. Bf2 e5
18. dxe5 fxe5
19. Rc2 Qb5
20. g4 Qd3
21. Rg1 exf4
22. Nf3 Qxd1+
23.Kxd1 fxe3
24. Bxe3 Be7
25. Rh2 Be6
26. g5 Bd6
27. g6+ Kg8
28. Rhh1

(28. h6 Bxh2 29. Nxh2 d4)

28... Nf5
29. Bg5 Kg7
30. h6+ Kxg6
31. Be7+ Kf7
32. Bxd6 Nxd6
33.h7 Rh8
34. Ng5+ Ke7
35. Re1 Ne4
36. Nxe4 dxe4
37. Rxe4 Kd7

Black looks good with ideas of ...Bf5, Ne5 and also push his pawns on the Q side up.  White may draw, but ...  I think the onus in this line is on White, not Black.

Improvements or changes for White here? or Black?

I note with pleasure that Prie takes a look at the 1.d4 d5 2.Bf4 c5 3.e4 gambit in the d-pawn special update.

I would have loved to see a comment on 5...a6 6.a4!? but I assume we must wait for practical OTB tests (and 6.Qe2 seems to be doing fine).

His 3...Nc6 recommendation is interesting. There is however something strange after 4.Nc3 cxd4 5.exd5 dxc3 6.dxc6 Qxd1+ 7.Rxd1 when he says that 7...dxc6, which is illegal, is equal. I assume he means the natural 7...bxc6, but then a word or two about Johnsen/Kovacevic' 8.Bc7!? would have been helpful.

7...   O-O 
8. Bd3 Nh5 

Black seems to get a good game game here but none of this is mentioned anywhere.  I have my own material on this, some of it goes past move 30.  White has wasted time with his dark bishop so this time taken by Black is compensated or paid back by White.  Any champions for White here? 


I posted a reply to this just before the server crashed. I try to repeat it before doing any new analysis.

MY PRE-CRASH REPLY
In contrast to your previous suggestions (among them 8...Qe7), 8...Nh5 looks distinctly suspicious. So I spent some time looking for an outright refutation. I didn't find a very clearcut one, but after 9.Ne5, Black at least has practical problems. Unless Black plays 9...Nf6, he has the following options:
a) 9...Nxg3?? 10.Bxh7+ Kh8 11.hxg3+-
b) 9...Bxe5? 10.Bxh7+ Kxh7 11.Qxh5+ Kg8 12.dxe5 +/-
c) 9...g6 looks weakening. After 10.f4 cxd4 (10...f6?! 11.Bxg6 should come to the same) 11.exd4 f6?! (Black probably should try 11...Qb6 or 11...Qc7) 12.Bxg6 fxe5 13.Qxh5 hxg6 14.Qxg6+ Kh8 15.Qh6+ White seems to have a clear advantage. 

If you find one of these lines playable for Black, I will be happy to look deeper into it.

1. d4 d5
2. Nf3 e6
3. Bf4 c5
4. c3 Nc6
5. e3 Bd6
6. Bg3

{In general, this is  quite a reasonable idea. The bishop withdraws and to enforce a trade, Black will have to open the h-file for White's rook.}

6....   Nf6
7. Nbd2

(7. Bd3 O-O 8. Nbd2  Qe7 9. Ne5 transposes to another line discussed before the server went blank.  This is OK with Black.)

7...   O-O
8. Bd3 Nh5

Black seems to get a good game game here but none of this is mentioned anywhere.  I have my own material on this, some of it goes past move 30.  White has wasted time with his dark bishop so this time taken by Black is compensated or paid back by White.  Any champions for White here?

I am ready/prepared to discuss this thouroughly.

I always play like this (Ne5+g4) why is this so bad? I keep winning them all Smiley


Looks like a good reason not to play 3. ...Bg4. After reading the review on Silman's site and looking at the variations offered I'm tempted to pick up this book. I've never opened 1.d4 in my life!
  

Those who want to go by my perverse footsteps play such pawn structure with fuzzy atypical still strategic orientations

Many thanks for this, tafl. I understand what you mean about crashing the server!

Yes, I'd love a copy of the posts as a Word file, just if you got time! -- many thanks! The address to send it to is: michael.ayton@voro.fsnet.co.uk

It wouldn't be that much work if I could post it as a Word-file or as pure text. But I would hate to crash the server, ao I will wait for advice from a more experienced user on how to do this properly.

However, if somebody wants to message me with their epost, and specify whether they like a txt-file (270Kb but hard to read) or a formatted Word-file (3.3Mb looking pretty much like the Forum), I will be happy to send a file.
