O-O 9. Be2 Na6 10. O-O Re8 11. f3 Nc7 {Ivanchuk`s ability to not only play any
opening, but any type of position due to his sheer versatility makes it almost
impossible to really prepare against him. Vassily's choice of the Benoni shows
that he is willing to take chances in this game and it is quite fitting that
the first game with this line as black was played by Tal.} 12. a4 Nd7 13. Kh1

pawn splitting the black forces, white goes for the jugular.} Bxb2 {Although
this seems to ignore white's obvious threats, it doesn't seem as black had any
good moves left to protect himself.} ({If black were to try and cover the
d-file with} 28... Bd4 {white would still follow up with} 29. f5 $1 Bxd7 30.
