I don't know if this is true for anyone else, but i find that i play my best in matches where i am really outclassed, and really don't have much of a chance. i'm guessing it is so because I am so much more relaxed then I usually am. In a way it is kind of frustrating because I would win a lot more matches if I could do this against players more of my caliber, but it is nice to be able to say you hung with whoever for two sets
