I usually start the match off thinking about my opponent. If I've played them before, then I usually stay pretty relaxed throughout, thinking of common strategies I know they use and how to best combat them to my advantage. If I've never played them before, I'm usually pretty tense at the start of the match. My first life is usually used to figure out attack patterns [if any] and find weaknesses that I can exploit. 2nd life is for testing strategies, and if it works, I just keep repeating, if it doesn't I use my third life to find any weaknesses I found in the 2nd life. My 2nd life, I'm usually pretty relaxed, and my last life, I'm always tense. My hands always sweat too, nothing changing that. I also have a tendency to keep a watch on my %, and whenever I have a higher % than my opponent I usually start to play a little more aggressive and tense up.
