For Caoili, currently the top ranked Australian woman, the event should serve as a good workout (probably one of many she'll enter) leading up all the way to next year's Olympiad in Khanty-Mansiysk, Russia. Her biggest challenge in London is likely to be IM Susan Lalic.
Unfortunately, it looks like all the resources for the event are focused on the main classic, hence PGNs from the women are not available. Hopefully, that will soon be corrected.
