Flop A [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/heart.gif[/img] SB c, BB c, hero cbet 45. SB folds, BB raises to 140. Villain has another 200 behind. I am approx. 85% sure he has better than 1 pair, possibly AQ. Can I fold this? What is more +EV, assuming he calls my push with AQ, AJ,and sets. A fold or push?
