Wait for your moment. I once played against a live opponent who raised $20 blind every hand. Kinda killed the action at the table, because $3 was the big blind. So if you were playing a hand you had to play it for $20. He got busted out by my QQ and another player behind his QQ.
Just pick your moment. Sounds like a terrible player, should be easy to stack. (Thinks back to my first
online poker days, 4 years ago...)
