The rule of thumb is very simple - we play ...Bb4 to provoke Bd2 before placing the bishop, to take away the option of Nd2 and e4. The exception is 4...Be7 5.Bg2 0-0 6.0-0 dxc4.


The last comments didn't adress this. While ...Bd6 without Bb4+ first ist not a problem at all, the Bb4-Bd6 line is very serious. Kramnik has used it himself against his old weapon.
Yes, Avrukh covers the line in GM 1A, but his coverage is already outdated as he doesn't mention an important early ...h6 option after White corrects the position of his bishop via Bg5. This is covered from black perspective by Pert in his recent Ragozin book.

It's in the book. But it was also in a PGN update QC posted after Avrukh's first GM Rep didn't have it in the book. But in any case, it's pretty well established at this point that 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.g3 c6 5.Bg2 Nbd7 6.O-O Bd6 7.Nfd2! O-O 8. Nc3 is pretty bad for Black, as a knight landing on e4 after 9.e4 gains a tempo or wins the bishop pair. So essentially you get an improved version of the normal Closed Catalan with ...Be7, which is also slightly better for White to begin with.  Grin

Yes, and it was covered by Bologan recently for those interested.  But there's not much to know: just play an early Nc3, Nf3-d2, and then e2-e4.  The threatened fork means that Black usually captures on e4 and White wins a tempo back because a knight on e4 hits the unprotected Bishop on d6.


Are you referring to Bologan's "Powerful Catalan" book or ChessBase DVD? Or did he write an article somewhere recently? I ask because I'm interested to know what he thinks.

This is treated by Hilton and Ippolito in Wojo's Weapon's Volume 1.

The short answer is that you can play b3 and wait a little bit with sensible moves. If black breaks too early in the centre, e.g. with ...e5, then dxe5 followed by cxd5 leaves black with an isolated pawn, and a likely bad version of the Tarrasch.

Does anybody know if Avrukh still recommends 8.Nbd2 in the Closed Catalan?

But isn't there a recipe from recent years that is supposed to be better for White, probably involving preparing e4 with Nd2?

I just discovered that I already had an update by Avrukh via the Quality Chess site... Indeed with Nd2 and e4!

Shame on those 1600-1900 players; don't they know they're supposed to play grandmastery stuff covered in grandmastery repertoire books?    Smiley

I recall that some older books considered that ...Bd6 (with ...c6/Nbd7/0-0) approach as leading to equality.  But isn't there a recipe from recent years that is supposed to be better for White, probably involving preparing e4 with Nd2?

Avrukh discusses ...Bb4+ then ...Bd6 in Catalan 1A.

OK, thanks! He doesn't discuss that in GM1. But it still makes a (huge) difference with 4/5...Bd6 without Bb4+ first.

I felt the main-line coverage was very light, suffice to say one line he retreats the Bg5 to h4 and does not even mention later Black has ...g5 winning a piece for 3 pawns, deserves a mention at the very least, the comp thinks Black is fine.

Might you expound upon what you didn't like? I mean, Black has found decent ways to combat the main line, so Avrukh has moved on to something else to provide an advantage. And as far as the depth of coverage goes, it's actually deeper, or at least more material has been added. Volume 1 had ~200 pages of Catalan stuff, and this new volume has 250...

I've had a look at it in the bookshop and frankly I am amazed and stumped. He has dumped the main line Qxc4, Bd2 etc for the a4 line, but I am deeply un-impressed. Seems very light compared to his previous efforts.

I haven't seen 1A, but if it's similar to 1, then I don't think that it's necessary for a 1900-player.  You could use it as a reference, but better to read something else like Bologan's book or even Dunnington's old Winning With the Catalan (a fantastic book) first. 

As a 2200+ player I didn't find that Avrukh's book helped me much at all OTB.  It was just too big and dense.  Good for a reference or correspondence I guess, but overkill for my level of opening preparation.

I have this for a few days. Short answer is yes, not only is it updated in many parts, some main choices are changed completely. Important changes are in main Open Catalan, 7. Dc2 dxc4 8. a4 (not 8. Qxc4). Another is main line Benoni Modern, 9...Te8 10. Af4 (not 10. Nd2).

I've already ordered it, but I haven't received it yet. I'll make some observations when I have had the opportunity to examine it thoroughly.

Any comments on this new book (compared to GM1)? Is it worth the buy if you are a 1900-player and haven't studied all of the Catalan of GM1 yet?
