Which time control was set in this game ?
I've looked all over the web and cannot find the specific time control used, but according to many sources I found via Google, this game was the 3rd round of the classical portion of the annual Russia vs China match, so definitely NOT a rapid/blitz game. I believe in recent years the classical time control for that event has been 40 moves in 90 minutes (relatively quick for that level).
