... I don't think many White players have prepared 6.dxe7, as you have to know a bit about 6...Qxe7 and 6...Qxd1+ 7.Kxd1 Bxe7/Nxf2+. While the first one seems a bit dubious, the latter two are unclear. Which white player knows all these lines?...


Cannot tell really, at least I have prepared for it and won a nice OTB game last year (opponent strived for 7...Nxf2+ which imo is rather difficult to play offhand as Black / I consider 7. KxQd1 Bxe7 as a much safer option). But bluffing is of course part of the game, so your decision basically.

Besides that, 3...Nf6 4.Nc3 cxd4 5.Qxd4 has not lost all its poison. Black can avoid 5...Nc6 6.Bb5 by playing 5...a6 (avoiding 6.c4 due to the Nc3), but 6.Bg5 entering Richter-Rauser structures is not everybody's cup of tea, either.


Regarding Richter-Rauzerish stuff, I have the impression that 5...Bd7 (which, like ...a6, is an old book move without ...Nf6 and Nc3 in) should be preferable to 5...a6 (6. e5 Nc6 7. Qa4).  There is also 5...e5, when one possibility is to transpose to an old main line of the Moscow via 6. Bb5+ Nbd7 7. Qd3.

At first, the risk being confronted with 4.dxc5 is really low. I have play this move-order a lot and the majority of the opponents plays 4.Nc3.
Furthermore, I don't think that 4.dxc5 is dubious for Black, if he knows that he has to play 4...Nxe4 5.cxd6 Nc6!, which is in my opinion the only equalizer, as all exd6, Nxd6 and Qxd6 don't look very promising. I don't think many White players have prepared 6.dxe7, as you have to know a bit about 6...Qxe7 and 6...Qxd1+ 7.Kxd1 Bxe7/Nxf2+. While the first one seems a bit dubious, the latter two are unclear. Which white player knows all these lines?
Besides that, 3...Nf6 4.Nc3 cxd4 5.Qxd4 has not lost all its poison. Black can avoid 5...Nc6 6.Bb5 by playing 5...a6 (avoiding 6.c4 due to the Nc3), but 6.Bg5 entering Richter-Rauser structures is not everybody's cup of tea, either.

Of course, sometimes you will face 4.dxc5 but this a) OK for Black and b) you will be probably better prepared than your opponent.


Of course the option you mention is a valid one and you also avoid the Hungarian (3...cxd4 4. Qxd4) and also discourage a delayed Smith-Morra gambit (e.g. 3...cxd4 4. c3), but I do not necessarily agree with your 2 points above for the following reasons:

(a) Not sure this is ok for Black as there are a few nice unbalancing or gambit lines for White that could work very well. Of course with perfect play both sides can claim sth, but it is not an easy game for either of them. You are usually heading outside Sicilian waters which may suit you or not (e.g. with the Hungarian or the Smith-Morra or the Prins your setup remains a 'Sicilian' one).

(b) When I have prepared the Prins line, I complemented it also with analysis of 3...Nf6 4.dxc5. I think a White player that wants to rely on the Prins for a while will do the same. On the other hand, if you think White is experimenting it is indeed a good idea to use 3...Nf6.

My 2c

I hope you will forgive me for reviving this old thread, but the question is interesting and the answer rather simple:
Black can avoid 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.f3 by playing 3...Nf6!.
Of course, sometimes you will face 4.dxc5 but this a) OK for Black and b) you will be probably better prepared than your opponent.
There is no better way for White but 4.Nc3 and after 4...cxd4 5.Nxd4 Black has his usual open Sicilian.

I've been giving this a look as White—and I like what it offers White. The Maroczy Bind themes are familiar to me from years of playing 1.Nf3 with Reti, English, and Catalan positions. But can anyone recommend a comparable alternative after 1.e4 c5 2.Nf3 Nc6?

I suppose you mean 8. Be2 O-O 9. O-O d5  ?
I think White may still have something after NxNc6, cxd5 & e5 - the position is reminiscent of the French Advance.

As for 6. ... d5, you may be right, I think it is mostly recommended after 5. Bd3 instead of 5. f3, i.e.: 5. Bd3 e5 & whenever possible ...d5.

The best coverage on this line is probably 'Dangerous Weapons: The Sicilian'.

I tried this line a few times, but lost interest in it because I couldn't prove any advantage whatsoever for White after 5...Nc6 6.c4 e6 7.Nc3 Be7 8.Be3 0-0 9.0-0 d5. 5...e5 is also playable for Black, as long as he avoids meeting 6.Nb3 with the popular but inferior 6...d5?!. One model game for White against this inferior line is Naiditsch-Petrosian, Aeroflot Open 2005.

Does anybody know an good source on this cheap but seemingly acceptable way to play some open sicilian without having to learn too much theory? I surely find a lot of games - even on high level - in my database, but no coverage in books.

By the way, there is not much discussion about it in the forum either. Does anybody use it as white and wants to share his experiences?
