Harikrishna played some subtle chess with the white pieces and went on to win the game. If you look at Harikrishna's games from this event, you begin to realize that he is hardly looking for an opening advantage. What he is more interested in is fighting chess. He is able to use the technique of constantly questioning his opponent and making him err. Take for example the following position.
Harikrishna vs Jakovenko
There are a lot of uninspiring ways to play in this position like b3 or g3, but Harikrishna has this unique approach where he is able to find resources that do not drastically alter the evaluation of the position, but definitely puts a serious question to his opponent on how he should continue. Hari played the move c5!
The position was equal for quite some time, but then Jakovenko went wrong and gave the Indian GM a chance to create a passed pawn. Hari did not miss it and won his fourth game of the tournament on a trot.
If you too would like to play the 5.Re1 line against the Berlin like Hari did against Jakovenko, you might want to check out Shirov's latest DVD for ChessBase on this subject.
