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.}

few interesting ideas in the following games Gelfand-Aronian 2007 and

position has occured only three times in tournament practice, and has been

{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.
