My claim that the line were good for White was exaggerated, but so was your suggestion above that 6.Bd3 would lose. Can we agree that both sides are fine after 23.Ra7 a4 24.c4, or 23...Nd7 24.Rxa5? Or do you want to win an ending like g4 (white) vs g5 (black), with 2N vs R ?


After 23...Nd7 24.Rxa5 Nxe5 I certainly would not give a draw if White offered it, would you?  On the other hand, I don't think White would be unhappy to accept if Black offered. You may be right that technically, it's drawn; I don't have the skill or knowledge necessary to judge that.

After 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bf5 6.Bd3 Bxd3 7.Qxd3 c6 8.Bf4 e6 9.O-O-O Bd6 10.Be5 O-O 11.Ne4 Nxe4 12.Qxe4 f6 13.Rhe1 Re8 (13...Bb4 may be best) 14.g4, what do you say to 14...Bb4 with the idea 15.c3 Bxc3 16.bxc3 fxe5 and now 17.Nxe5 Nd7 or 17.dxe5 Qe7?

I think what I said about 6.Bd3 is that is not that it loses, but that it's a dubious move because it offers to bring off White's best attacker.  For the time being, I maintain that opinion.

One feels that's finally the right way to play the Blackmar:
castle quickly and bring a rook to the f-file.

Let me quote myself: on page 2 I was saying that in the case of long castlings,
Uruk wrote on 05/17/09 at 07:06:28:

White could develop long-term pressure on the kingside pawns.
It also happens in the normal Caro, so everybody castles short without fear now.


You lured me exactly into castling long, so my rooks have to defend on g8 & f8
and I can't seriously think about winning.

So it's possible White has a draw with 6.Bd3, unless Markovich comes up with some very precise moves.

Stefan,

Are we looking at the same position, or am I missing something?

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bf5 6.Bd3 Bxd3 7.Qxd3 c6 8.Bf4 e6 9.O-O-O Bd6 10.Be5 Bxe5 11.dxe5 Qxd3 12.Rxd3 Nd5 13.Ne4 b5 14.Nd4 O-O 15.Rf1 a5 16.Nc5 Ne7 17.Ncxe6.  It appears to me and my silicon buddy here that 17...fxe6 18.Rxf8+ Kxf8 19.Nxe6+ Kf7 20.Nc7 Ra7 21.Rd7 Rxc7 22.Rxc7 is all quite forced, and after 22...Ke6 I really don't see that White is better.  Rather I much prefer Black.

Maybe 14.Qg3 is an alternative: 14...Rg8 15.Rdf1 0-0-0 16.a3 Rdf8 17.Kb1 Nd7 18.Bf4 Nb6 19.Rf2 Nc4 20.Qd3 Qa6 (20...Nxb2 =; 20...b5 21.Bc1) 22.Bh2 Bh4 23.Rf3 f5 24.a4 Bg5 25.Ka2 and White has full compensation for the pawn. 

Analyzing 6.Bd3 I have the feeling that White can vary his plans and still retain sufficient compensation. 6.Ne5 may be sound, I don't know. But here I can understand Uruk's doubts, the move seems too risky.

True, that's another hard nut to crack. Let's try: 16.gxf6 Nxf6 17.Nxf6+ exf6 18.0-0 Be7! (18...Kf7 19.d5 cxd5 20.Be3 is less critical, e.g. 20...Rd8 21.Rxf6+) 19.d5 cxd5 20.cxd5 Rd8 21.dxe6!?, e.g. 21...Bc5+ 22.Be3 Bxe3+ 23.Kh1 Qxd1 24.Raxd1 Bd4 25.b4 Ke7 26.Rd3 Be5 27.Bd5 Rc8 28.Bb3 Rhd8 29.Rh3 h5 30.Rg1 Bd4 31.Rd1 Rd6 32.Rg3 g5 33.Rgd3 Be5 34.h3, White has good chances for a draw. - But I admit that 6.Ne5, though it may still hold the balance, would be frustrating for White in otb play. Maybe someone else has better ideas to justify the move.

Yes, maybe 12.h6 isn't as strong as I had hoped. So I try: 12.Ne5 Nxe5 13.Bxe5, e.g. 13...h6 (Rg8!?) 14.Rdf1 0-0-0 15.Kb1 or 14...Qa6 15.Qf3.

Stefan, you gave 6.Bd3 Bxd3 7.Qxd3 c6 8.Bf4 e6 9.0-0-0 Bd6 10.Be5 Bxe5 11.dxe5 Qxd3 12.Rxd3 Nd5 13.Ne4 b5 14.Nd4 0-0 15.Rf1 a6 16.Nc5 Ra7 17.Rdf3 and so forth.

That's a long line and not forcing. I think that Black might improve with 15...Ne7 (intending 16.Nc5 a5) or 15...a5 (intending 16.Nc5 Ne7) instead of 15...a6.  No doubt White has better activity, but I'm not sure if it translates into anything.  Meanwhile Black has his pawn and at least won't have to worry about his king.

However, (15...Ne7 16.Nc5 a5) 17.Ncxe6! is good for White.

I'd prefer 13.Rhe1 Re8 14.g4 Bf8 15.Bg3. White has compensation, e.g. 15...Qd5 16.Kb1 Nd7 17.Qe2 Nb6 18.g5!? fxg5 19.Ne5.

Well, that is a possible line.
In any case, to enter this position against a technical Black player is asking for trouble.
In addition, a more aggressive option would be 15...f5!?

Black argues he'll get his own g-file.

See my reply #37. Sorry for my mistake regarding the move numbers, so please read 10...Bxe5 for 11...Bxe5, and so on. The explanation is that in my file I still have the inaccurate move-order 6.Bd3 Bg6?! 7.Qe2?! Bxd3 8.Qxd3, which added a move for both sides.

Hello everybody, I will respond to the main subject about ..Be6 soon but Iam being very busy these days and for a few days. But I have seen that the idea Bd3!? is discussed where "in the past" I said that I think ..Bg6 to be better than ..Bxd3, mainly after a game played at corr where I was Black. I did not obvious errors, and I liked the way he played his attack (with simple piece development and castle in the kingside with a quiet attack) to get a forced draw.

[Corr]
[Date "2006.08.22"]
[Round "1"]
[White "Plante,Marc-Eric"]
[Black "ArKheiN"]
[Result "1/2-1/2"]

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 c6 6. Bc4 Bf5 7. O-O e6 8. Bd3 Bxd3 9. Qxd3 Nbd7 10. Bg5 Be7 11. Rae1 O-O 12. Ne4 Nxe4 13. Bxe7 Qxe7 14. Rxe4 Rad8 15. Re3 Nf6 16. c3 h6 17. Ne5 c5 18. Rg3 cxd4 19. cxd4 Rd5 20. Qe3 Kh7 21. Qd3+ Kh8 22. Qe3 Rc8 23. Rf4 Rb5 24. b3 Ra5 25. a4 Rd5 26. Rgf3 Kh7 27. Qd3+ Kg8 28. Rxf6 gxf6 29. Rg3+ Kh8 30. Rg6 Rg8 31. Nxf7+ 1/2-1/2

I shouldn't be surprised if some BDG players would like to test this position in practice.

Perhaps I should add that 6.Bd3 isn't new, of course. There are 30 games in the database. 6...Bxd3 7.Qxd3 c6, and in the next moves 12 of 13 White players castled short, which is a bit strange. Only the idea to combine Bf4 and 0-0-0 seems new.

Stefan, 

Thank you for providing the diagram.   

All, 

I am overwhelmed
   by the number of positions 
you quote in one post. 

     So I will leave with this ragged verse in time 
and let others do the wandering.

Stefan, your Qf5-d7 idea is cool. [..] White is left shuffling his heavies looking for tricks.

(23...Qf5) For example: 24.Bxh8 Qd7 25.Qe1 Ne6 26.Qe4 Rd8 27.Rd1 Bh6 28.Kh1 Nf4 29.Rg3 f5 30.Qf3 Kf8 31.Be5 Ne6 32.d5 Ng5 33.Qg2 Nf7 34.Bd4 (Bc3) Kg8 35.Bc5 Rc8 36.b4. White may be slightly worse, but he won't lose.

After 9...Be7 10.h4 Nbd7 11.Ne5 O-O (show me!)

White plays 11.h5 h6 (what else) 12.Kb1, for example 12...0-0 13.g4.

@Markovich: 11...0-0 12.Ne4 seems okay for White. 
11..Bxe5!? is in fact a critical variation. I had planned 12.dxe5 Qxd3 13.Rxd3 Nd5 14.Ne4 b5 (so far your analysis) 15.Nd4 0-0 16.Rf1 a6 17.Nc5 Ra7 18.Rdf3 h6 (18...Rd8? 19.Ncxe6 Re8 20.Ng5) 19.g4 Rc8 20.h4 Re7 21.g5 Nd7 22.Nxd7 Rxd7 23.gxh6 gxh6 24.Nb3 c5 25.Nd2 and White has compensation for the pawn. 

6.Bd3 looks fully playable to me, but maybe I am wrong. It is one of these positions where you feel that White has some pressure, but maybe not enough. On the other side, White's compensation is a lot more concrete than in the Soller Gambit, and I shouldn't be surprised if some BDG players would like to test this position in practice. To exchange Black's strongest defender, the Bf5, is a logical plan.

5...Bf5 6.Ne5 e6 7.g4 Bg6 8.Qf3: in my database White scores 71% (86 games). Proves nothing, but it is rather Black who needs some improvements here.


Well, we should discuss the rights and wrongs of that either in another thread or perhaps here after we have dispensed with 6.Bd3.  But one thing I am very much not impressed by is statistics in these gambit systems, so we'll eventually have to get into the actual chess of it.  Black of course plays 8...c6.

Stefan Buecker wrote on 05/17/09 at 19:00:02:

Regarding 6.Bd3 Bxd3 7.Qxd3 c6 8.Bf4 e6 9.0-0-0 Bd6, the last move was the main line in my analysis, and White's reply is 10.Be5. See reply #7 for more details.


Ah, now I see that.  But I wonder why Black was made to play either 10...Be7 or 10...Bc7.  Why should he fear 10...0-0? For that matter, why can't Black just concede d6 outright and play 10...Bxe5 11.dxe5 (I assume your plan is not to play a pawn down with no bishops on the board) 11...Qxd3 12.Rxd3 Nd5 13.Ne4 b5, after which I doubt that White's sinking a knight into d6 is really going to help him very much.  Black is not without play of his own, for instance eventually ...Nd7, ...Ne7, ...Ng6.

@Uruk: Yeah, I understand the point of ...Be6, I just think that ...Bg6 is a strong move.  Further after 6.Ne5, 6...e6 does happen to be a line.  If you like Black in the first diagram, you and I have very different ideas of how to play chess.  But in general I think you're too shy about asserting Black's chances.  He's a pawn up and has no weaknesses, for crying out loud.  Should it bother him that White has some pressure down the e- and f-files?  

Stefan says that if White is more active and Black has no pawn breaks in the near future, White has comp.  Well fine, the only problem is that Black is a pawn up and the course of a chess game is not limited to the next ten moves.  In such a position I am very happy to shift my pieces around and eventually find some way to simplify.  Without a clear plan for White, there is no way I would want his side of it.  (I myself am by no means reluctant to gambit a pawn, by the way, just not my e-pawn on move two unless Black's first move is 1...f5).
