After starting with 5/5 Vassily Ivanchuk completed a dominant victory in the Mtel Masters, scoring more 4 draws before winning his final game against Ivan Cheparinov. His final score of 8/10 left him a point and a half ahead of Veselin Topalov, and a tournament performance rating of 2977.
Probably the other surprise tournament performance was by Lev Aronian (spotted recently visiting the Australian National University), who finished in a tie for last place on 3/10 .
Here is the final win for Ivanchuk, holding off a determined, but ultimately unsound attack from Cheparinov.
