Yes, Chakvetadze could certainly be a major roadblock to the semifinals. Like any Hingis-type player, she is exactly the kind of player who could give Petrova fits and pull an upset if Petrova is having a bad day.
But having said that, Antwerp is a very winnable tournament. Petrova has beaten Mauresmo several times and Clijsters will be feeling the pressure of winning at home in her final season and just might crack under it. But, as always, one match at a time.
