What to do vs a....

80/67 with 61% to steal? Just shove with any decent hand? He has gone all in with stuff like 73s to hit a flush and etc...

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...)
