Regarding that sequence, Paul Boersma's article had 16...cd 17. ed e5 and 16...Ba6 as leading to = or unclear (with a few annotated/cited games).

(edit:  the 16...Ba6 part is less clear; he did give one line as leading to +=.)

Here's the opening sequence in one of those correspondence games:

My main reason for saying this was a couple of correspondence games I played where Black got ground down in long positional battles.

That, and the games that are available to everyone that seem to show White's edge.

Which begs the question: what games and analysis did the Yearbook article refer to that made it look like 11.a3 isn't good for white?

I'm not sure what the basis is for saying that "Schandorff's" 11. a3 gives White "a tremendous pull"; a Yearbook article a few months ago didn't seem to think so, for example.

NGU, if you read through the thread and peruse Aronian's 11.Bc4 and Schandorff's 11.a3, you will find that White has a tremendous pull in both lines.

The caveat is that White's edge requires a deft touch and a level of positional mastery rarely found below 2200 strength in OTB chess. Below about 2200, the Cambridge Springs should be just fine.

For me this is an interesting thread since I've been stuggling with the CS as white. I used to get very good results with 1.d4 d5 2.c4 e6 3.Nc3 Nf6 5.Bg5 Nbd7 6.e3 Qa5 7.cd5: Nd5: 8.Qd2 N7b6 9.Bb3 Nc3: 10.bc3: Nd5 11.0-0 Qc3: 12.Qe2. But I'm playing a local FM on a regular basis who plays the better 8. ... Bb4 9.Rc1 and I have been struggling to achieve anything substantial with white. With white, you get good development and a centre, but if black defends carefully and throws in an appropriately timed e5 then he should be all right - or is he?

I think the CS is under a cloud because white has more than one way to gain an advantage. Aronian's 11.Bc4 is certainly interesting, but White will still be fine even if this particular idea gets ground down.

Btw, the first example of 11.Bc4 that I have found was in Solak-Blagojevic (2005). Perhaps it should be known as Solak's novelty, not Aronian's?

In the recent CBM (142 143) It seem that the cambridge-springs is 'under a cloud'.
Mainly because Aronian's novelty

In CBM 118 and 119 Rogozenko did a two part repertoire for black in the Cambridge springs - basically covering 1 d4 d5 2 c4 e6 3 Nc3 Nf6 4 Bg5 Nbd7 5 e3 c6 6 Nf3 Qa5 7 Nd2 and 1 d4 d5 2 c4 e6 3 Nc3 Nf6 4 Bg5 Nbd7 5 e3 c6 6 Nf3 Qa5 7 cxd5.  For everything else you need something else, The Cambridge Springs by Krzysztof Panczyk & Jacek Ilczuk is OK.

I've seriously considered playing this opening for some time, but I'm always slightly unsure about the exchange variations.

trw, the pawn sac lines generally come after 1 d4 d5 2 c4 e6 3 Nc3 Nf6 4 Bg5 Nbd7 5 e3 c6 6 Nf3 Qa5 7 cxd5, white is committed to several here e.g.

7 cxd5 Nxd5 8 Qd2 N7b6 9 Bd3 Nxc3 10 bxc3 Nd5 11 0-0 Qxc3 13 Qe2

and after

7 cxd5 Nxd5 8 Qd2 Bb4 9 Rc1 there are a host of similar lines after a sequence like a3 Bxc3 bxc3 Qxa3.  Kramnik-Bruzon, Turin Olympiad 2006 is a an example quoted by Schandorff.

Is this still viable? Anyone know who the top players are who play this on a regular basis? Any theory changing novelties in the past few years?

The only point of reference I have on this line is from the starting out series by Mcdonald.


If you're after a very solid defence to 1.d4 then the Cambridge Springs is a decent option.

It's a great opening at lower levels as well, since most players below 2200 aren't willing to play the critical pawn sack lines.



which critical lines are you referring to? Can you post them?

On the other hand, White can deviate till the last moment with cxd5, so Black has to be familiar with the dialectics of the Exchange Variation, especially if he's a  former semi-slav player.

I'm not so sure that 11.Bc4  is the best idea for White here.  Schandorff considers 11.a3 to be "standard by now". Play usually continues with 11...Bc3 12.bc3 b6 13.c4 Qd2 14.Nd2 and then Black has a choice between 14....Ne7 and 14...N5f6.

I've seen this variation a couple of times in correspondence recently. I like White's game because the position seems to favor the player with the better positional judgement.

Either side can still win, so I can understand why it's popular with people like Shirov.

(Edited to correct a grammatical mistake.)

Believe the prolific Andrew MArtin has just brought a DVD out on this.
I think it's certainly playable at club level.
More playable the lower the level - as it's not straight forward to deal with.

Shirov used it this year in Wijk aan Zee against Anand and Aronian. Against Anand he made a serious blunder, but against Arionian it was a fascinating struggle despite he lost that one as well. But this doesn't mean the Cambridge Springs is in theoretical trouble, just that Anand and Aronian are brilliant players.
