If he is shortstacked, I fold
If he is deepstacked, I fold
Ill ask if we can run it twice, then I fold on any or no answer
I buy him another beer, make sure he knows where the ATM is and become good friends with him before I take his bankroll.
I make him my facebook friend for giving me 3 buyins over the next 3 hours.
I invite him to my homegame and if I dont have a homegame I set one up and invite him.
In all situations, I laugh out loud and show him my aces as I say to the guy behind me"What a donk, any side bets on how long before he goes broke?"
