Hi there,

which move do you think is the best for white in the "Poisene
Pawn"-Variation of the Sicilian Najdorf:

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb
8. Qd2 Qxb2 9. Rb1 Qa3.

There seem to be three main moves: 10. f5, e5, Be2.

Which do you consider to be the best?

Greetings
Raine

The main line is 10. f5. After 10... Nc6 11.fxe6 fxe6 12.Nxc6 bxc6
13.e5 dxe5 4.Bxf6 gxf6 15.Ne4 Qxa2!? you're in good company in saying
that Black is OK, as this was the variation that Kasparov chose in his
game against Vallejo Pons in the Armenia vs. the ROW match.

See: http://www.chessgames.com/perl/chessgame?gid=1290137

As far as what's most dangerous for Black, in the new and excellent
book, Experts vs. the Sicilian, Thomas Luther recommends 9. Nb3
(instead of 9. Rb1). He cites a few of his own games, including
Luther-Quezada, Merida 2003. Btw, Quezada, an IM from Cuba, won that
tournament!

Here is the game: http://www.chessgames.com/perl/chessgame?gid=1271217

Pretty impressive. Dreev annotated the game in NIC 1/2004, and noted
that 22. f6 had been given a question k by both Kaspaprov
(annotating his game with Short, Riga 1995, and by Bonsch, annotating
the Kasparov game in CB magazine). It turns out, however, that after
22. f6! Qc2 23. f7! Nf7 24. Rf2, the Black Queen is trapped and White
wins.

Hope this helps,

Hello,

as far as i know,
a) 10.e5 is thought to be harmless (this is the move which was applied in
the early times of the variation).
b) 10.f5 is interesting, i personally think that the variation 10... Nc6
11.fxe6 fxe6 12.Nxc6 bxc6 13.e5 dxe5 14.Bxf6 gxf6
15.Ne4 Qxa2!? is ok for Black although it looks very risky.
c) My personal preference is 10.Be2 with speedy development although i think
Black has good equalizing chances in the variation 10... Be7 11. O-O Nbd7
(or 11... h6!?, or 11... Dc5!?).

The general problem is that White has often to sacrifice more material in
order to get real pressure, but this often leads in some variations to
nothing more than a perpetual. Just one example in the 10.Be2 line: 10...
Be7 11. O-O Nbd7 12.e5 dxe5 13.fxe5 Nxe5 14.Bxf6 gxf6 15.Ne4 f5 16.Rb3 Qa4
17.Nxf5 (this is probably the only move, 17.Qc3 is maybe already a lost
position for white) 17... exf5 (White has sacrificed 2 pawns and one knight)
18.Nd6+ Lxd6 19.Qxd6 Qe4 20.Re1 Nc6 21.Kf1 Be6 and now Nunn gives in his
(old) book (1988 :-) ) 22.Bf3!? and 22.Bh5 (the latter leading to a
perpetual check).
He thought that 22.Bf3 is +-, but i think it�s in fact -+ so i guess White
has nothing better than a draw in this sharp line.

22.Bf3 Rd8! (instead of 22... Qc4+) and what should White do?
22.Bh5 Qc4+! 23.Rd3 Nd8 24.Qd7+ Kf8 25.Qd6+ Ke8 26.Qd7+ perpetual check

Of course, there are so many possibilities in this sharp variation so i
think it�s hardly possible to tell whether 10.f5 or 10.Be2 is better. In my
last correspondence chess match, i tried 8.Nb3 instead of 8.Qd2 Qxb2 9.Rb1
Qa3, but i didnt have luck with this move. :)
