I need to be making more folds like this one?

[aflaba]

I didn't fold. To the best of my knowledge a call is not EV+ here. But calling on the river for one bet comes so natural to me. I feel I need to be giving up and folding more in hands where my opponents can't have anything that I beat, duh.

What do you think?

Opponent is 20/13 regular. I don't know anything about him other than that he is a regular.

The other guy is 80/15.

Preflop: Hero is BB with A[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/diamond.gif[/img].
UTG calls, <font color="#CC3333">Button raises</font>, <font color="#666666">1 folds</font>, Hero calls, UTG calls.

Flop: (6.50 SB) 7[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks, UTG checks, <font color="#CC3333">Button bets</font>, <font color="#CC3333">Hero raises</font>, UTG calls, <font color="#CC3333">Button 3-bets</font>, Hero calls, UTG calls.

When he 3-bets I figure I must be beat by a bigger Ace (or better).

I need to see the river for my outs 2*A, 2*9, 2*7 and probably some high cards.

Hero should fold? He missed his draw?

Final Pot: 12.75 BB.
