hmmm if his AF is 1.7 and he's very loose looking preflop i think i call because that's not really loose passive is it? If he's loose passive obv an insta fold but im sure these fish stack with tp here too... Oh i dunno, 43/13 is just spewy looking to me.
Edit: chuck beat me to it but i think thats what i meant, this guy is surely not being a passive bitch post flop?
