1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 {The truth is that
Fluviбґs choice surprised me. His results with the Sveshnikov have been quite
good in the past few years, and although he has flirted with other lines, this
has always been his favourite weapon. Although in the first round Fluviб had
already gone for the Najdorf against Lуpez Martнnez, I thought that was part
of some specific preparation. It took me a while before I settled for...} 6.
Be3 {The English Attack is my usual choice against the Najdorf, although 6.Be2
and 6.Bc4 are also part of my repertoire. For some reason, I had the feeling
that my opponent likes 6...e5 set-ups against 6.Be2, which is considered by
theory as the easiest route to equality. But something made me believe he
would rather play with 6...e6 against the English Attack. Thus, I came up with
the following "trick": I play 6.Be3, and after 6...e6, I go for 7.Be2, as
Adams has tried so many times. Ok, it is not like this is so great, but those
structures suited me fine in a must win situation.} Ng4 {Hmm, and now what. I
did not feel like going for those crazy lines after 7.Bg5, so...} 7. Bc1 Nf6 {
and back to where I was. So, I am not the best psychologist. After some more
thought I decided to go for a line I consider interesting but had never
employed before,} 8. g3 e5 9. Nb3 Be7 {Personally, I prefer 9...Nbd7, followed
by ...b5 (or ...b6 if White plays 10.a4). Fluvнб adopts a very "Najdorf"
approach, controlling d5 and not giving any contact points on the queenside.}
10. Bg2 Be6 11. O-O Nbd7 12. a4 {Whiteґs plan is to first put a pawn on a5,
fixing the queenside, and then jump into d5 at some point. Black will have
nothing better than taking the intruder, and after exd5, a typical position
with flank majorities will be reached. I like White because he has a little
head start on his side of the board, but these positions a very complicated in
practice.} O-O (12... b6 13. Nd5 Nxd5 14. exd5 Bf5 15. f4 {leaves the bishop
in trouble, since} exf4 {is met by} 16. Nd4 $16) 13. a5 {This position
resembles the Karpov Variation of the Classical Scheveningen, but here the
bishop on g2 gives White a superior version. The main advantage is the extra
support of d5; on the downside, not having a bishop on e2 putting pressure on
a6 allows Black to play ...b5. This, however, does not give him full equality.}
b5 ({Another idea would be} 13... Qc7 14. Be3 Rfc8 {trying to hold back Nd5
for the time being. The truth is, though, Black cannot manage this in the long
run. One possibility is} 15. h3 {, followed by 16.Qd2 and 17.Rfc1. In similar
positions in the Karpov variation, Black puts his queen on c6 and controls d5,
but the extra control exerted by the g2 bishop makes this attempt futile.}) 14.
axb6 Nxb6 15. Na5 Qc7 16. Nd5 {During the game I thought this move was clearly
the best one and played it instantly. In a similar situation, the great 6.g3
expert, Petar Popovic, preferred to finish his devolopment first, not giving
Black any clear play on the kingside. I now believe} (16. h3 $1 {, followed by
Be3 and Qd2 might be more precise.}) 16... Bxd5 {A strange decision, but the
idea will be clarly understood after Blackґs next move. The alternative is} (
16... Nfxd5 17. exd5 Bd7 {, and try to push the kingside pawns. White,
meanwhile, should take advantage of the weakened c6 square. One idea could be}

allowed to protect d5, then the weakness on c6 will tell.} 18. g4 $5 {Risky,
but the tournament situation was crying out for this one.} ({After the game my
opponent suggested} 18. f3 {, which I rejected because it seemed to me that my
dark squares were weakened too much. But what was really worrying me was the
necessity of parting with my light-squared bishop, which would leave my king
exposed. On the other hand, maybe these were nothing more than excuses thought
up to convince myself to play 18.g4.} Nfxd5 ({we looked at} 18... e3 {in the
postmortem, but} 19. f4 Nfxd5 20. c4 {refutes it.}) 19. fxe4 Nf6 20. e5 dxe5

be weaker after the exchange of the h-pawns, but he underestimated the rook
manoeuvre on move 22.} (18... Rae8 {and now:} {The thematic} 19. Ra3 {is also
possible here} (19. c4 Nxc4 20. Qc2 Rc8 21. g5 (21. Nc6 Ne5 22. Rxa6 Nxd5 23.

Blackґs next is forced.} g6 23. Rh3 {Black has neutralized the main threat,
but has weakened the a1-h8 diagonal in the process. Besides, Qg4-Qh4 is still
a possibility Black needs to be prepared for. Right now there is ...Kg7,

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. g3 {This move
represents the common attitude to the openings nowadays - instead of trying to
win the game by preparation, White is simply aiming for a playable game. It's
not a big surprise that 6.g3 has become more popular recently - it's hard to
imagine that White can fight for anything special in the main Najdorf.} e5 {
The most principled reply. Black could try many moves, but this one seems most
logical.} 7. Nb3 Be7 8. Bg2 b5 (8... O-O {was another option. The move in the
game is a bit more aggresive and there is absolutely lot of sense in delaying
castle for a moment. If Black managed to put his pieces on the best squares 
(Bb7, Nbd7, Rc8), White could be worse.}) 9. Be3 $5 {This is a new move, I
believe. It's not impressive, not at all, but it makes some sense, as the
bishop takes the a7-square under control and that square is useful for the
black rook in many lines.} ({The main move here is} 9. a4 {which leads to an
equal position after} b4 10. Nd5 Nxd5 11. Qxd5 Ra7 12. Be3 Be6 13. Qd3 Rb7 {.})
9... Nbd7 ({The point of 9.Be3 is easy to see in the following line:} 9... O-O
$6 10. a4 b4 11. Nd5 $14 {and Black can't take on d5.}) ({However, Black could
try the simple} 9... Bb7 10. a4 b4 11. Nd5 Nxd5 12. exd5 $11) 10. a4 b4 11. Nd5
a5 $2 {A big positional blunder. when you have the knight on b3 you dream of
seeing the black pawn on a5, which makes the knight position very good, if not
perfect. Of course, there are a lot of situations where there is nothing wrong
with moves like a6-a5, but in this position Black gets nothing in return.} ({
The most natural alternative was} 11... Nxd5 12. Qxd5 Rb8 {. Now White would
be rather forced to play} 13. Qa5 {in order to show that the whole plan had
some idea in itself. However, the position after e.g.} (13. Na5 $2 Nf6) 13...
O-O 14. O-O Nf6 15. Qxd8 Rxd8 16. Rfd1 Be6 {is simply equal - White can't make
any use of the a5-square and all other factors, especially the c-file, show
that Black must be fine.}) 12. O-O ({It's not a bad move, but it was better to
play} 12. Nxe7 Qxe7 13. Qd2 $1 {with a nice edge, as White can press on the
d-file. Unfortunately, this line works only because of the tactical trick
which I missed - after (now or later)} Bb7 $2 {White can play} 14. Nxa5 $1 Rxa5
15. Qxb4 $16 {. Missing this, I could decide on this line, as I thought White
is losing his e4-pawn.}) 12... O-O 13. Re1 $6 {Again, Nxe7 was better. As I
didn't see the tactical trick mentioned in the previous comment, I decided to
put the rook on the e-file in order to have the e4-pawn protected in some
lines.} Bb7 14. c4 $1 {This is not what White could get after taking on e7 on
more 12th or 13th, but after c2-c4 White still keeps some advantage - all in
all the pawn on a5.} bxc3 $6 {I believe this is a mistake.} ({Probably better
was} 14... Nxd5 15. cxd5 Bg5 $1 16. Bxg5 Qxg5 {and it seems that Black is just
in time to coordinate his forces in defence, e.g.} 17. Rc1 (17. Qc1 Qd8) 17...

it's much easier to press on the queenside than to prepare a counterattack in
the centre.} Qb8 16. Qd3 $1 {A strong move. White's goal is to put the knight
on b5, but since the knight is protecting the e4-pawn, it's neccessary to find
a new defender for the pawn first.} Rc8 $6 ({Black could have tried} 16... Bc6
17. Nb5 Nb6 {, but White still would keep an advantage after} 18. Rec1 Bd7 19.
Bf1 $14 {. Still, it was better than the game.}) 17. Nb5 Bc6 18. Bd2 Nc5 {
This move is not a dream scenario for Black, but sooner or later it was
neccessary to exchange the superstrong knight from b3.} 19. Nxc5 dxc5 20. b3 {

White is a pawn down, but it's just a question of time when he will win it
back. Once the material becomes equal, White will keep a serious plus, as the
knight is a powerful piece and can attack the a5-pawn on many occasions. At
the same time White is much more active.} Qc8 ({It was probably better to keep
the pawn by playing} 25... Bf6 {. However, it's visible that after} 26. Rd7 {
White would be much better.}) 26. Qxe5 Bf8 27. Qd5 {I must admit that during
the game I was sure that my position was not just better, but simply winning.

is worse, but White must be very precise.} Qg4 $2 {In such positions it's
better to wait. Much better was the calm 27...g6.} 28. Nd6 $1 {After this move
Black is even worse coordinated than before 27...Qg4.} Ra7 (28... Rd8 {wasn't

number of options the better side has. You think that you are winning after
every move and it's easy to lose control and miss the moment when you should
play precise moves again!} g6 30. Re1 $6 (30. Rd3 $1 {was much better, because
the rook on d3 would be really multifunctional, defending b3, sometimes
helping to exchange the queen on d8 and also, sometimes would be ready to join
a direct attack on the f7-pawn. On e1 the rook is much worse placed, as it
only targets the e8-square, which is not a big deal.}) 30... Qd4 31. Qf3 Qd8
