Well I have been recently poring through Richard Palliser's provocative Fighting the Anti-Sicilians and finding it quite informative and enjoyable. The chapter on the Closed Sicilian is particularly interesting but there is an important possibility for White that he failed to consider in one of his mainlines that goes as follows:
[Event "Linares 16th"]
[Site "Linares"]
[Date "1999.02.21"]
[Round "5"]
[White "Adams,Michael"]
[Black "Kasparov,Garry"]
[Result "0-1"]
[Eco "B26"]
1.e4 c5 2.Nc3 d6 3.g3 Nc6 4.Bg2 g6 5.d3 Bg7 6.Be3 Nf6 7.Nge2 0-0 8.h3 e5! facilitating a later b5 without allowing any e5 tricks on the long diagonal 9.0-0 b5! apparently a strong novelty at the time 10.Nxb5 Rb8 11.a4 a6 12.Na3 Rxb2 And Kasparov being Kasparov, went on to win in 59 moves. Ok, that's all well and good, but rolling back to move nine White could play in my opinion the stronger 9.f4!? which seems to pose Black a few more problems.
See the following game for an illustration of the potential dangers facing Black:
[Event "Pardubice op"]
[Site "Pardubice"]
[Date "1995.07.??"]
[Round "0"]
[White "Jurkovic,Hrvoje 2355"]
[Black "Voitsekhovsky,Stanislav"2500]
[Result "1-0"]
[Eco "B26"]
1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 d6 6.Be3 Nf6 7.h3 0-0 8.Nge2 e5 9.f4!? Nh5 10.f5 Nf6 An admission of failure, and after 11.g4 Ne8 12.Qd2 Nc7 13.0-0-0 White had a big advantage and went on to win in 38 moves. One logical place to look for improvements for Black would be move ten, however the natural looking 10...gxf5 11. exf5 Nd4 12. Nxd4 exd4 13. Qxh5 dxc3 14. O-O cxb2 15. Rae1! gives White a strong and probably winning position.
So my question is what is Black's best counter to White's 9.f4!?.
Let the analysis begin.
