round, I chose a system which never happened in my practice before. However,

Indian, which I played more than once.  Genau wie in der ersten Runde wдhlte
ich ein System, das noch nie in meiner Praxis vorkam. Doch die Grundideen des

faces a dilemma - to advance her f-pawn to one or two squares. The restrained
Gligoric system 11. f3 is more flexible - White fortifies her center, reducing
Black's counterchances. Victoria prefers a more aggressive approach. WeiЯ
steht vor einem Dilemma - soll der f-Bauer ein Feld vor oder zwei? Das

Vorgehensweise.} 11. f4 {From now on White should plan her actions, keeping in

also clear - to prepare the advance ...b7-b5. An immediate Na6-c7 is less
precise as the knight may sometimes get to the much more active position on b4.

understand the idea behind this move. Perhaps White thought the rook might
cover the d3-square in the future, but actually it looks like a waste of time.

1. d4 Nf6 2. c4 e6 3. Nf3 c5 {Choosing the opening against Igor is not an easy
task. His repertoire has not changed a bit over the last 20 years and he has
enormous experience in virtually all the openings. I quickly discarded the
Gruenfeld and the King's Indian, but noticed that he had not faced the Benoni
too many times. This was the only field where my experience was by far
superior, which explains my decision. There was one thing I failed to notice
during my preparation: Igor likes to sacrifice material under unclear
circumstances, for the sake of taking over the initiative. This aspect was
highlighted by Oleg Korneev during the post-mortem. Had I known this in
advance, I may have chickened out and played the Slav or something.} 4. d5 d6
