I had this guy outplayed for the first 20min...then he starts catching and making some rediculous hands. Who's playing these differently, and what's your line?

Is anyone laying down two pair to the turn RR A-I?

I whittle him away some more(not even 10 hands later). I think I'm getting good odds for it, but we're deep stacked. Is anyone folding here?
