About the analysis in variation B1, White is perhaps a bit better after 16. Rad1!? (instead of Rac1) and I think 16. Ng5 Bf5 17. Qb5 Rc8 18. Rfd1 looks better for White as well.

I know this is an old thread but the 6.dxc5 variation is an annoying one from Black's point of view.

I put, "1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.dxc5 Nf6 7.Be3 Be7 8.g3 0-0 9.Bg2 Ng4!", on Stockfish and it thought both 10.Qxd5! and 10.Nxd5 were better moves than 10.Bd4.  It still looks rather complicated but theoretically speaking White maintains a plus according to what I looked at.


Hey there !

Time has passed since fall 2016 - I am older now and much more cynical with my outlook on life and chess.  Wink

I wonder about my optimistic "!" for 9..Ng4!?  .. I mean surely it is an interesting variation but I do not think it deserves the exclamation mark..

I did not give myself the chance to test my old analyses. I did not face 6.dxc5 in over the board games since 2015 and in blitz I always stuck with 6..d4 .

Against stronger opposition though I would prefer the standard 6..d4 (which is just fine imo for black despite white having the two bishops). However if you play against a weaker opponent 6..Nf6 is well worth a try since finding the critical lines over the board is everything but an easy task. I consider it a good practical blitz weapon but maybe not the ideal solution for classical time controls.

Would you mind sharing your analyses (10.Bd4 / 10.Qxd5 / 10.Nxd5) ? Maybe we can find some improvements for black together Smiley

2, after 12. h3 Nh6!? 13. g4 Rc8, White seems better after 14. Rc1. E.g. 14...f5 15. g5!? Bxg5 16. Nxg5 Qxg5 17. f4!, followed up by Nd2-f3-e5. White's minor pieces are better than Black's and it looks kinda like a Stonewall gone wrong to m


I apologize but I do not follow..
How can you play Nbd2 If you have both Knights on f3/c3 ?
In the line mentioned B2) 12.h3 Nh6 13.g4 Rc8 and now 14.Rc1 isn't the white pawn on c5 just hanging with tempo due to 14..Bxc5 ?
Maybe it is a misunderstanting on my part so I would kindly ask you to quote the whole variation in question.



Sorry, my mistake, I mixed up your line with another one  Embarrassed . Didn't check on a board from the start of the variation. The position I looked at had White castled instead of the knight on c3. You are totally right that you don't understand me.

I don't see the point of 12. h3. Why spend a move to force the knight to a better square. 12. Nbd2 looks more natural to me and I can't see compensation for Black

Anyhow, in your line B2, after 12. h3 Nh6!? 13. g4 Rc8, White seems better after 14. Rc1. E.g. 14...f5 15. g5!? Bxg5 16. Nxg5 Qxg5 17. f4!, followed up by Nd2-f3-e5. White's minor pieces are better than Black's and it looks kinda like a Stonewall gone wrong to me.

Sorry about the the mess I created.

But the fixed pgn isn't correct, some lines are missing and the explanations are on the wrong places  Huh

Anyway, then I'll continue the old-fashioned way.

In the line

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.dxc5 Nf6 7.Be3 Be7 8.g3 0-0 9.Bg2 Ng4! 10.Bd4 Nxd4 11.Qxd4 Be6 12.h3

A) 12..Nf6 does not seem to do the trick.

Following 13.Ne5 Qc7 14.Nd3 Rc8 15.0-0 Bxc5 16.Nxc5 Qxc5 17.Rfd1! it seems that white has the usual slight pull.

A1) 17..Ne4 does not work for multiple reasons
A11) 18.Nxe4 dxe4 19.Bxe4 /Qxe4
A12) 18.Nxd5 Bxd5 19.Bxe4 Qxd4 20.Rxd4 Bxe4 21.Bxe4 with an extra pawn in the rook ending

Better is
A2) 17..Qa4!?, preventing the queen trade
A21) 18.Nxd5 Nxd5 19.Bxd5 Rcd8 20.e4 Bxh3 is no problem
A22) 18.e3 Rfd8 19.a3 Rc4 20.Qd3 h6 and not much is happening. The isolated pawn is well protected and if e4 there follows d4. If black wants to try something I guess he has to play a5-b5-b4 to fight for the entry square on c2.
A23) 18.b4!? seems critical 18..Qa6 19.Nxd5 Nxd5 20.Bxd5 Bxh3 21.a4 Qxe2 22.Qxa7 looks a bit unpleasant indeed.

But we don't have to play 12.Nf6 in the first place.

B) 12..Nh6!? is far more interesting

B1) 13.0-0 Nf5 14.Qd3 Bxc5 15.e3 Ne7 16.Rac1 Rac8 17.Rfd1 h6 18.Nd4 Qd7 and the exchange on e6 is not problematic as the black centre would restrict the bishop on g2. Maybe black can even keep the bishop pair with earlier more clever play.

B2) 13.g4 tries to play against the knight on the rim but weakens the dark squares around the white king 13..Rc8 and we are getting back our pawn and keeping the bishop pair

B22) 14.Qd3 Bc5 15.0-0 f5! provoking 16.g5 Nf7 17.h4 and now there are several candidates such as 17..Qd6, 17..Nd6!? , 17..f4 and 17..d4 .

B23) 14.b4 does not achieve to hold the pawn 14..b6! 15.0-0 (15.cxb6 Bf6) (15.c6 Rxc6) 15..bxc5 16.bxc5 Bxc5 (16..Rxc5!?) 17.Qd3 f5 18.g5 Nf7 19.h4 and we are basically reaching B22) but with the b-pawn being exchanged

Any opinions on 7.Be3 with my novel 9..Ng4 idea ?

6.dxc5 Nf6!? in the Tarrasch

Hey guys.

I always found the 6.dxc5 line in the Tarrasch (1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.dxc5!) to be slightly annoying.

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

Following the mainline with 6..d4 7.Na4 Bxc5 (regaining the pawn, but surrendering the bishop pair) 8.Nxc5 Qa5+ 9.Bd2! (9.Qd2 I dont consider a problem) 9..Qxc5 10.Rc1 (10.b4!? is a very interesting gambit continuation) 10..Qb6 11.e3 Nf6 12.Bc4 dxe3 13.Bxe3 Qb4+ 14.Qd2 Qxd2+ 15.Kxd2

we reach an endgame / a queenless middlegame which I dont quite enjoy playing as black

White got the bishop pair and the exposed king is not much of a problem, in fact in an endgame it quickly joins the action.

Ntirlis and Aagard conclude that this variation is equal. I tend to agree, but in my opinion black is playing either for a draw or a loss with no real winning chances.

That is why I searched for an alternative to this endgame-line and it seems that 6..Nf6 is quite an interesting approach.

Defending the pawn and "threatening" Bxc5 without the usual tempo loss Bf8-e7xc5. White has to something, otherwise black will just play an improved Tarrasch, basically being up a tempo.

I analyzed it a bit.

A) 7.Bg5 tries to pressurize the isolated pawn on d5 but Black does not have to hold on to it.

So A) 7.Bg5 does not seem to be too problematic.

In GM 10 - The Tarrasch Defense Ntirlis and Aagard give
B) 7.Be3! as the critical choice, holding onto the c5-pawn and preventing ..d4.

But are things really that clear.. ?




Interesting or rubbish ?
I can very well imagine that it is better suited to outplay your opponent as it is the case with 6..d4.





.. It seems the castling move is not shown in the pgn.  Huh


Can somebody please fix it ? What did I do wrong ?
