Maybe GlennMirnyi, but now it says that it's played on Rukothard which is not carpet.
Maybe it's new for this year?
Comments from some WTA players:
Serena Williams: The surface of the court is kind of weird - Serena noted. - It is rather slow and the ball bounce is sometimes high, sometime low, - it is kind of unusual for me because indoor courts are typically faster.
Anna Chakvetdaze: It is as slow as the previous one but the rebound is high
Svetlana Kuzenetsova: I hope that I will get accustomed to the surface laid on the court of the Olimpiysky stadium as we had already played on the same surface in the Fed Cup
So it seems like the surface has changed and GlennMirnyi owes the thread starter an apology
