Yeah get the practice in where you can.
This is oddly the best part of my game. Its The rest of it that sucks.
Heads up live.
Always watch your opponents reaction, eg when dealt pockets, when flop comes. Dont look at your cards until you have seen his reaction.
You should read up onstandard hu play. eg raise any cards both over 9, suited conenctors etc.
Probably, its about trapping this guy. Bet out where you wouldnt. Not every time just 35-40% take a risk, lose a few chips but wait for him to miss read you. Reraise him in situations that you have nothing. I find live that if the guy knows how im playing i throw in some real random crap. It puts them off as when you come storming in under something and they think you bulls*ing again you've got him. Personally, i would check all flops and let him make the play then you can reraise etc when appropriate even with bottom pair.
Be prepared to let a few chips go to waste in order to catch him off guard. You only have to have the hand once for him to make a mistake.
