A suited ace plays best in a multiway pot I think and so I am not defending this to an utg raise, where we are often going to be dominated. Defending with it will often get you into tough spots, as you found here. Because heads up you are not getting the odds to play for 2 pair or better type hands, when you do decide to defend here you are going to have to peel when you do get top pair, and of course you have to continue when you get trips on the turn, and even though you are often behind on the river I think you have to call there too, though really you now just have a bluff catcher against a missed flush, or against a thin value/blocker bet with KK type hands. So as played, I am check calling each street but I prefer to avoid these tough spots and am folding pre.

Thanks for your comments guys and all are valid arguements. The reason I defended is exactly what fkcoolers said, we are 46 bb effect with nut suited ace vs a guy who also very deep and we are looking to smash a flop. Agreed when you hit top pair your not loving it and it most situations you will be in C/ C mode. On the river we are indeed bluff catching and the way he played this hand hes never betting a hand worse than ours OTR. I have a feeling pro's like goleafsgoeh fold here pre but I really need some clarification as to what is the optimal play.

hate flatting out of position here as it makes it very difficult to have a beleivable line at the end id rather you 3 bet here and outplay villain than flat and fold ur chips away but 3 betting here is bad as well as its your first hand i fold and dont put myself in these spots where i have to pay off all better aces.
