Fascinating, but I was wondering what to do after 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. f3? I'm sure you can guess what kind of sicilian I want to transpose back to...


One of the main differences between guarding e4 with Nc3 as opposed to f3 or Bd3 in many lines of the open Sicilian is Nc3 influences d5 as well as e4.  So while allowing transposition to your favorite defence is playable it may pay to see whether you can vary here as black.  Classical wisdom says 5.f3 is weaker than 5.Nc3 and I think that's because  black can play an early d5 and live happily ever after. 

Since 5...d5 seems to fail to 6.e5 why not try 5....e5 followed by d5?  I think you'll find black is ok here but if not or if you don't like playing the resulting positions and prefer the standard dragons then I don't think white can vary successfully from those because if he could do this then most probably someone who plays much better chess than any of us would have been doing it long ago in this particular position.

What about 5....d5?  It's tricky but black seems to be a little better e.g.  1.e4 c5 2.Nf3 Nc6 3.d4 cd4 4.Nd4 Nf6 5.f3 d5 6.Bb5 de4!? (6...Bd7?! 7.Bc6 Bc6 [bc6 gets the same answer] 8.e5 and white's a little better) white has to be careful.  Black is better after 7.o-o Qb6 8. Be3 e5. White seems a little worse after 7.Nc3 as well...Bd7 8.Bc6 bc6 9.oo e5.  If the above are true then White has to settle for 7.Nc6 and the forced endgame after 7...Qd1+ 8.Kd1 a6 9.Ne7+ Ke7 and black seems better here as well.
Alternatives to 6.Bb5 (6. ed5, 6.Nc3, 6. Nc6 is there anything else? 6. Be2-d3-c4 seem hard to believe as does 6. g3) also seem colorless and give up hope for a white advantage or transpose.

It seems to me that the most logical way to exploit having played ...Nb8-c6 instead of ...d7-d6, is to play 5.f3?! d5! (in one move!).  If White wants to play e4-e5 now, he will have to play 6.Nxc6 bxc6 7.e5 Nd7 (or maybe even 7...Ng8!? planning ...Ng8-h6-f5) when Black looks fine - he has counterplay down the b-file and can control d4 by playing ...c6-c5 at some point.

One point is that if 7...Nd7 8.f4, I think Black can play 8...Ba6!? taking advantage of the fact that White has not played Nc3 yet (9.Bxa6 Qa5+).  In the French-type positions resulting, exchanging the light-squared bishops is clearly to Black's advantage.  The king will find a nice safe home on the kingside (no pressure on the b1-h7 diagonal!) and he can hit the White centre with ...f7-f6 at some point.

It is no exaggeration to say that it is White who is struggling to maintain equality here, imho.

I've played the Sveshnikov quite a few times,
but as yet not had  5. f3 played against me.
If 5. ... e5 does not appeal then how about Qb6
putting the question to the Nd4 and/or switch to a Dragon formation.
It is also possible to get into the Sveshnikov via
the 2.  ..  e6 move order  which would help with  playing d5 against f3, but this of course allows White different possibilities.
As it is said - choices, choices.
Cheers,

I know in the 2 ... d6 vars this move is considered an acceptable alternative, but after 1.e4 c5 Nf3 Nc6 d4 cxd4 Nxd4 Nf6 f3!? is there some sort of way for black to deal with this?  As a Sveshnikov player e5 seems to transpose out into a weirder Kalashnikov...e.g., e5 Nb5 d6 (d5 is a blunder) c4 and it's closer to a Kalashnikov with Nf6 and f3 thrown in...

Any ideas?
