Rustam Kasimdzhanov had a significant advantage against Alexander Grischuk in round 1 before slipping and losing in time trouble, but in round 2 of the Tbilisi Grand Prix today he maintained his advantage and won against Shakhriyar Mamedyarov.
The other five games were drawn, though not always smoothly. For instance, Alexander Grischuk won a pawn against Dmitry Andreikin and had good winning chances. Maybe Andreikin could have held even against perfect play, but Grischuk didn't find the best plan and let Andreikin off relatively easily.
If you believe your engines, Anish Giri was winning against Maxime Vachier-Lagrave, but I wonder if the whole thing, from start to finish, was worked out to a draw by MVL with the assistance of his computer.
Leinier Dominguez was surely winning against Peter Svidler, and with a bigger advantage than Giri had against Svidler when the latter resigned in their round 1 game. Svidler has been known on occasion to resign somewhat prematurely, but unfortunately for Dominguez this was not one of those days. Svidler defended like a lion for hours, and it paid off.
Finally, the Teimour Radjabov - Baadur Jobava and Dmitry Jakovenko - Evgeny Tomashevsky games were both drawn without anyone getting into serious trouble, though this should not be understood as a claim that the games were "soft". They weren't.
After two rounds Grischuk, Tomashevsky and Giri lead with 1.5/2, Vachier-Lagrave, Svidler and Jobava are tied for last with half a point, and the other six players are in between. Games (no notes) are here.
