Offhand I thought that 7...cd 8. Nxd4 Nc6 might be allowing White "better than he deserves," like maybe 9. Nc2 with the idea of meeting ...Nd7 with Qd2.


I thought about 9.Nc2, but after 9...Nd7 10.Qd2 Nc5 White has to deal with the threat to the e-pawn with 11.f3, and now Black might try 11...f5!? to exploit White's slight delay in development.  This is just "chess by smell" though, as Markovich might say.  Maybe Black should settle for something a little less ambitious.

I think it's important to not get too carried away in trying to punish White, though.  He didn't play the most theoretically challenging move, but I don't think that he's made an actual mistake yet.  Black can probably get equality more easily than normal, but I doubt you'll find more than that.

Edit: White may try 11.Bh6 instead of 11.f3 I guess, but then 11...f5 or 11...Bxh6 12.Qxh6 f5 looks OKAY for Black.  Still, maybe Kylemeister's recommendation is better, my only point was that playing simple moves seems perfectly acceptable for Black.

@OP, if you want to play for a Bind, then 7.dxc5 is a reasonable move.  For example, 7.dxc5 Qa5 8.Bd2 Qxc5 9.Nf3 Bg4 10.Be3 Qa5 11. 0-0 Nc6 12.a3 Rfc8 13.b4 Qd8 etc.

In this line, there is a cute trap after 10.Be3.  The tempting 10..Qb4 is met by 11.a3 winning a tempo.  The point is that Black can't play 11..Qxb2 because of 12.Na4 winning the Queen.  As I.A. Horowitz once said, "He who takes the Queen's Knight Pawn sleeps in the streets."

Hmm, in my opinion as a 6.Bg5 Saemisch player, I would like to have the Bishop on g5 if I could, even in a Maroczy Dragon.  The idea is not so much Bxf6 followed by Nc3-d5, but rather Nc3-d5 first with enough pressure in certain situations to induce ...Nxd5, after which White can play e4xd5 with pressure against e7.

Of course, I said "if I could."  I don't think it's feasible here, as White isn't controlling the d4-square well enough.  In addition to Kylemeister's ideas, I'd consider simply 7...cxd4 8.Nxd4 Nc6, hitting d4.  After 9.0-0, have we transposed into Accelerated Dragon "theory?"  To me it  seems Black can be satisfied with hunting down the dark-squared Bishop now with 9...Nxd4 10.Qxd4 h6 11.Bh4 (11.Be3 Ng4!) g5 12.Bg3 Nh5, for instance, but this is just my gut feeling.  I don't think that White has anything better on move 9, and otherwise he has to play the clumsy 11.Bd2 or Bc1.  Seems Black should be fine.

Well white doesn't often play for the sort of e file breakthrough where the bishop would help gang up on e7. All it can really do is hope for a Bxf6 ^ Nd5 style sort of trick.

You can see how it makes sense after d5 rather more easily - the pin on the f6 knight for instance.

Still, unless black has some concrete way to exploit the dark squares (as in the post above) it's probably playable. You want to be asking an engine about that Smiley

Generally it would be thinking of going to e3.  In the line you suggest, the bishop looks something of a target; Black can think about possibilities like 7...h6 8. Bh4 g5 10. Bg3 g4 11. Nh4 Qb6 or 8. Be3 Ng4 9. Bc1 cd 10. Nxd4 Qb6.

That's what I am asking. Why is it a problem to have a bishop on g5, when it can pressure f6 and e7? Where should it be?

After the sequence in the Averbakh KID 1.d4 Cf6 2.c4 g6 3.Cc3 Fg7 4.e4 d6 5.Fe2 O-O 6.Fg5 c5, I wondered if one could play 7.Nf3, instead of the usual 7.d5, to invite to a transposition into an accelerated dragon (Maroczy Bind)?

Are there any significant differences with a normal AD? It looks like an usual position with Be2, 0-0, etc.

Thx!
