Also, Suetin showed how white gains an advantage after Nxd7 in ECO back in 1978.

6...Nd7 7.Nf5 hits the d6 pawn immediately. Now, 7...Nc5 (Zvaigantsev tried 7...a6 once, but lost)   8.Nc3 and black is:

  • Behind in development
  • has a weak d6 pawn (that in this position really is a target) and
  • his only developed piece will have to move very soon or get kicked.


See ECO B54 and B55 for some key positions and what black hopes to transpose to (tho many of those positions also look rather bleak for Black.)

This may be a dumb question, but why is it nearly always better to recapture with the queen in that type of position? Wouldn't Nxd7 develop another piece to a good square?


The knight would be better placed on c6 imo.

Looking at this line, I don't really see white's advantage after 1.e4 c5 2.Nf3 d6 3.d4 cd4 4.Nd4 e5 5.Bb5 Bd7 6.Bd7 Qd7 7.Nf5.

Grischuk tried 7.Ne2 twice against Grachev and scored .5/2.

This is from memory, but I'm pretty sure de la Villa recommends 7.Ne2 in Dismantling the Sicilian. I don't remember if he has much analysis of it, though.

I checked and de la Villa gives 7.Ne2 an exclamation point, although he doesn't really explain why. One double-column page of analysis follows, including at least one unplayed novelty, which I won't reveal out of respect. He does mention one of the Grischuk-Grachev games, saying that after 7.Ne2 Nf6 8.Nbc3 Be7 9.Bg5 0-0 10.0-0 Qe6 11.Bxf6 Bxf6 12.Nd5 Bd8 13.Qd3 "White has applied the thematic plan and has a lasting edge based on the grip on the d5-square and the fact that Black's dark-squared bishop is relatively inactive."

This could be a bit more venomous than it seems. It certainly seems like an excellent surprise weapon. 

Perhaps White's best is simply 5.Nb3 Nf6, expecting to transpose to more common lines?

Yes, that is the CD.
A fair practical punt - very unlikely white will play all the way down the critical line.

Bibs and OstapBender,

Thx for the hints. I'll have a look.

There is a chessbase CD on this and other 'alternate' (qb6 kinda stuff) sicilians.
Worth a look - plenty of interesting analysis therein and the best source.

Guess you mean Amador Rodriguez, Modern ways of playing the Sicilian, 1999 ...

Presumably Khalifman will also deal with this line in his Anand 1.e4 series. Vol. 10? Vol. 11?

Anyway, one or two games in a forthcoming update here would be nice ...  Roll Eyes

I would like to see some coverage of the line 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 e5 (or of the line 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5, which the first line often transposes to). "Theory" recommends 5.Bb5+ (or 6.Bb5+, respectively) as an "antidote", but it appears things are not so clear (cf. Nigel Davies' comment in Taming the Sicilian).

Is there a thread on these lines? (I haven't found any.) Are there games with these lines in the archives? (I haven't found any.)

There's a thread entitled A virtually unknowned Sicilian line here (though it's not a very long one).

These lines are also mentioned in Experts vs. the Sicilian and Beating the Sicilian 3.

There is no outright refutation, but White does fine answering ...e5 with Bb5+ coming out of the opening with a small plus.
