I meant to mention that in my post above. If the success of 12.a4 has taught us anything it's that White doesn't need to stop ...Ng4.

A comparable possibility which has come up in books (as at least slightly better for White) is 11...Na6 12. Re1 (doing without h3) Qb6 13. Re2 Nb4 14. Bf4 Qa6 15. Qd2 Rfb8 16. Ne1.

In the Alterman line, what about 11...Na6 12.h3 Qb6 13.Re1 Nd7 14.Re2 and now 14...Nb4!? instead of 14...Rfb8?

In many lines, Black can hurry with ...c4 and ...Nd3, but also prepares ...Qa6 straight away.

I suggest (along with my computer):

15.a4 (White wants to meet 15...Qa6 with 16.Nb5 - instead, something natural like 15.Bf4 is met by 15...Qa6 16.Rd2 c4! with decent comp) 15...Qb7!? (Black wants to play ...c4 without allow Be3-d4 with tempo) 16.Na2!? (My computer prefers this - other natural moves like 16.Bf4 c4! 17.Nd2 Qa6 or 16.Bg5 Rfe8 17.Qd2 Nb6 18.b3 f5!? seem to give Black good counterplay) 16...Na6!? 17.Bg5 (17.Nc3 just loses a tempo and allows 17...c4!) 17...f6 18.Bf4 Nc7 (18...f5 right might also be possible, as is regrouping slower with 18...Rfe8 followed by ...Nc7, ...Qa6, etc...) 19.Nc3 f5!? with a mess.

So what about 14...Nb4?

It may well be better to keep the black knight on d7 so that it can help out on the kingside if needed.

By the way, what about this game regarding the line 11...Nbd7 12 a4:



Is White really so much better if Black plays the usual Benko stuff (Qa5-a6, Rfb8, Ne8-c7 and so on)?

EDIT: Well, in this game White probably is better after 21 Ra3  Undecided

I noticed that this (another old game which has been cited as +=) is a close comparator to Alterman-Odeev; it seems that Vogt might have played better than Odeev.

Here is the score of the game without the comments. Alterman analyses it over roughly 6 pages.



After move 19 the author comments: "Fixing the pawn structure and securing control over the c4-square. Black lacks any real counterplay, and White will slowly turn his attention to the kingside."

I see that Gallagher had that (via a different move order) as leading to +=.  (I was going to take a look at how the Alterman game compares to the stuff Gallagher gave, but I couldn't find it.)

I read somewhere that the author of "Attack with Black", Valery Aveskulov, promised an update of his book since he didn´t cover 11...Nbd7 12 a4. Has this already happened?

12. Bf4 was given long ago as "!" (12...Qb6 13. Qd2 Rfb8 14. Rab1 Nc7 15. Rhe1 Nb5 16. Nxb5 Qxb5 17. b3 += Gligoric-Barle, Vrbas 1977), but I get the impression that it didn't catch on ...

Since Black seems to be in relatively rough shape in the 12.a4 line - I got to thinking about move orders to avoid it, and I wonder about:

1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6 g6 6.Nc3 Bxa6 7.e4 Bxf1 8.Kxf1 d6 9.Nf3 Bg7 10.g3 O-O 11.Kg2 and now 11...Na6!?

This has been played in quite a few games already, but I'm not sure it's been discussed here in any detail. The knight isn't amazing here, many times needing to relocate to c7. From here it discourages e5 by attacking d5 and looks to trade with White c3-knight via the b5 square. At the very least it discourages 12.a4!

A few games:







Black seemed mostly fine in these three games, with more improvements probably lurking. Does Kaufman cover this line?
