The Only first round matches this i think will be one sided are Serena vs Bovina (bovina's still in her comeback period) Golovin vs Muller and Petrova vs Malek and then second round onwards is just i'd only bet my house on henin winning. Even though Serena and Ivanovic/Schnyder could be be facing a qualifier in 2nd RD, The quali draw is tremendous too. They could be up against Kraijeck or Dulko. Kraijeck is a good player and Dulko is no pushover either. This could end up as a GREAT tournie.
good luck to tati, Serena and i hope schnyder cn beat ivanovic.
