Marin doesn't seem to cover the rare set-up for black where he plays c5, e5, Nc6, d6. What 5th move for white best fits into the repertoire Marin gives? 5. e4 (Botvinnik style) or 5. Nf3?

I still like Whites chances after 10...h5 11.h3 and now for instance: 11...Qg6 12. Nxc4 h4 13.g4 Nxc4 14.Qxc4 with a complicated position. Black might now try 14...Nxg4!? but I think White is fine still...

I would be very cautious of any book that claims to find an edge against all lines starting from move 2.  There is a lot of great analysis in Marin's books, but the more I read them the more I get the impression that Marin is almost willing white to be better.

I have just been flicking through volume 2 (particularly relevant to me as I have played both sides of a lot of these lines) and I have already found several lines where I would question the assessment of a white edge (generally because some sensible move for black has been ignored).

FYI, I really doubt that white has any kind of an edge in the line 1.c4 Nf6 2.g3 c6 3.Bg2 d5 4.Nf3 dxc4 5.0-0 Nbd7 6.Na3 Nb6 7.Qc2 Qd5 8.Ne1!?


After looking at the line you mention, 8 Ne1 i used Rybka 4 to take a look at the position. After 8..Qd4 9 e3 Qg4 10 e4. Marin mentions 10 ..e5 and also 10.. Qe6 which should be a tempo down on an other line according to him. After ..e5 the line ends with a clear advantage for white. After ..h5 however Rybka seems to like blacks chances so I am a bit worried that this option is not analysed. Suggestions anyone?

Which lines exactly in the anti-slav dont you trust? Im very curious myself about these lines because I find them highly complicating and agree with you that it might be one of Blacks best tries. However, I do believe that White has lots and lots options that lead to unclear positions often giving up the c-pawn for a very long lasting initiative.

Hey Jacob, I'm looking forward to seeing these anti-slav problems over some blitz in December.  Loser buys dinner?

P.S. leaving aside my reservations over the main line of the anti-slav system (which is what it is), so far I'm really enjoying book 3.


Hello Mr. Dearing,

how about a comprehensive update of your dragon book!?  ^-^

I think Marin's Anti-KID repertoire seems to be a +=; the variations resemble Closed Sicilian positions that are not very good for Black.

I did not have a chance to look at all lines in detail, but I found that they were very uncomfortable to prepare against, when I had to play a dedicated Marin fan this weekend. As his publisher this has happened way too often!

I basically disagree that 1.c4 and 2.g3 is not as challenging as 1.d4 or 1.e4. An advantage means that the opponent has problems to solve. Eventually everything is a draw anyway. I find that Marin has created enough problems to worry me in practice, but eventually all problems in chess should be solvable.

I basicaly agree. These are excellent books with a lot of verbal explanation about typical plans and strategy.
Of course it is out of the question to be assured of an advantage , but honestly even a 2700 GM has problems to get an advantage with white all the time, whatever the opening is.
Clearly the lines are playable and due to the explanations you should know what to to Wink

In the introduction to the first volume, Marin states that he had found a way to a theoretical advantage against every line starting with 1. c4 and 2. g3.

My copy of Volumes 2 and 3 are in the mail. In the meantime, I am curious, to anyone who has already  received the books, does Marin actually claim that his anti KID line leads to a theoretical advantage? 

Or is it more along the lines that he concedes that White really has to transpose to the finachetto KID to gain an objective advantage, but since that is already covered by Avrukh, he is offering an alternative practical weapon consistent with the rest of the repertoire.

Personally, I do think too much a fuss is often made by amateurs about whether a line leads to a theoretical advantage or not, but nonetheless, I am curious. 


I finally got my copies today so I can answer my own question. Browsing through them, it is clear that Marin is not totally convinced that his repertoire will produce a theoretical edge against all systems. He comes closest to admitting this in his coverage of the anti-King's Indian system. Fortunately, Avrukh offers good coverage of the fianchetto KID and Wojo's Weapons Volume 2 will soon be out to supplement this.

I got a similar impression in quite a few lines in his first book. I don't particularly mind, because I know that with 1. c4 and 2. g3 White probably shouldn't be better in all lines. It's just an interesting opening with complicated positions that I enjoy playing. Hopefully that's how a lot of readers look at it as well.


Yep, you are right.

How do you use these GM-repertoire books actually?
Do you really work it through or use it just as a reference book?

I sincerely doubt if 6.d2xe4 has been played in GM games.


Clearly I missed a move out (d3 0-0). Thanks for your useful comment though.


Your posts would be a little easier to follow if you included move numbers.

@anon3 Also Na3. Marin regards Bxa3 as the critical line leading to an unbalanced position, other moves he says give white a risk free "good-catalan" like game.


Can you be more specific here. After 1 c4 e6 2 g3 d5, does he recommend 3 Bg2 or 3 Nf3? Does he recommend meeting 3...dxc4 with the immediate 4 Na3?
