1. d4 Nf6 2. c4 e6 {Already a small surprise for me, recently Gata has been
played mostly the Slav Defence, but certainly the Nimzo/Queen's Indian still
remains in his repertoire.} 3. g3 c5 {A very unexpected choice by my opponent,
although there have been a few games of Gata's, in which he played the Benoni.}
4. d5 exd5 5. cxd5 d6 {So finally the game transposed to the "normal" Benoni.}
({Recently} 5... b5 {has been very popular for Black, but White has found a
few interesting ideas in the following games Gelfand-Aronian 2007 and
Kramnik-Alekseev 2007, where Black faced some problems in the opening.}) 6. Nc3
g6 7. Bg2 Bg7 8. Nf3 O-O 9. O-O a6 10. a4 Re8 11. Nd2 {The most popular move
in this variation, where I have scored quite well before this game.} ({The
alternative would have been} 11. Bf4 Ne4 {with complicated play.}) 11... Nbd7
12. h3 Rb8 13. Nc4 {The main direction.} ({I have tried} 13. a5 {a few times,
but Black gets good play after} b5 14. axb6 Nxb6) 13... Ne5 {Without any doubt,
this move is the most principal continuation.} ({Another line runs} 13... Nb6
14. Na3 {etc.}) 14. Na3 {Preventing b5-move.} Nh5 ({Quite interesting is} 14...
c4 $5 {which has been played in Avrukh-Gajewski, Dresden 2007.}) 15. e4 {
Otherwise Black will play 15 ...f5 with good play.} Bd7 ({Another interesting
option is} 15... Rf8) 16. a5 $1 {The only way to fight for the advantage.} (16.
g4 {is considered to be dubous, since after} b5 {Black obtains a fantastic
game.}) 16... Qxa5 17. g4 Nf6 18. g5 $2 {This is considered to be the best
option for White, but now after the present game I believe this move is simply
bad .} ({I think White should try another line} 18. f4 Nexg4 19. hxg4 Nxg4 {
with extremely complicated play.}) 18... Nh5 19. f4 Nc4 $1 {Black has tried
other moves here, like 19...b5, 19...c4, but the text is clearly the best one.}
20. Nxc4 Qxa1 21. Nxd6 Bxc3 $1 $146 {Very simple and very strong! This
position has occured only three times in tournament practice, and has been
considered slightly dubious for Black. Meanwhile this game completely changes
the assessment of this variation.} ({The recent game, where this position
occured saw} 21... Re7 $2 22. e5 {[%csl Ge7,Gg7]} Nxf4 $2 23. Bxf4 Qxb2 24.

additional option on his 24th move.}) 23... Rxe8 24. Rf3 ({Neither} 24. Qd2

all, two bishops and a strong center should be quite good compensation for a
pawn and White should be able to reach a draw.} Rc8 27. Bd2 a5 {This move was
played very quickly by my opponent, so I understood here, that he is still
following his preparation!} ({After the natural} 27... Rc4 {White has enough
time to create counterplay:} 28. Bf3 $1 Bb5 (28... b5 29. d6 Ng7 30. Bd1 $1 {

{Some time ago, a dear friend who does not really play the Benoni suggested to
me this (unplayed then) idea. A couple of years later, I showed it to my pupil
Daniele Vocaturo, who used it to get an excellent position against Grischuk,
although, to tell the truth, by that time there had been one game with it
already! Grischuk seemed to have liked the idea, since he took it up for a
rapid game against Aronian. When preparing to annotate the present game I was
surprised to find out that a few dozen games had been played in the meanwhile.
My non-Benoni friend's idea seems to have become one of the main lines...
During the press conference, both players confessed that neither of them
expected this line to be played. However, Bacrot had done his homework on
another occasion, while Ponomariov was kind of on his own. True, he remembered
something he had not liked as Black when trying to include this line into his
repertoire, but could not remember exactly what. Yet, Ponomariov jokingly
admitted that he was glad to play this kind of position. He was sure of one
thing: his series of draws would finally come to an end. He was proved right,
but not the way he might have hoped for...} 18. Naxb5 {Played after 25 minutes.
