Why are you three betting the flop here?

[Marquis]

I suppose the honest answer is: Because I am drunk.

Point taken, though.

I fold flop here-too much chance you're beat already and you have PFR behind you.

Poor flop play aside, how did I play the turn and river?

I'm not sure about this pre-flop play, either. Is open-limping bad in a 6-handed game?
