Re: Tips for tournaments please
I would say, tournaments for you should definitely be looking at these as chances to see where your game is and how you can take steps to improve. Don't really heed the results as how good/bad you're playing. Make your own judgment on how it went based on things like returns in court, winners, did you make your opponent play.
Also, be sure to have fun. This is a time where you need to continue to build a love of the game. It just gets real downhill with people calling their own lines...:ugh:
Serena , Venus , Petra , Ana 
Simona, Vika , Angie, Sveta, Garbiñe
Kim , Mahree , Monica , Dokic, Sandrine, Jie
