First, be sure to select 2+2 forums on the pulldown in the converter. That may be why the smiley's are showing up.

Now on to the hand...

Here you have to fear A2-5 and maybe even 56s. But you also have a good hand worthy of a showdown so you don't want to give up. But you also want pot control in case you are up against two pair or a straight. I probably would have led the turn and semi-bluffed having A2-5s or something. If I didn't get a fold I'm c/f the river unless its a small bet. By checking the turn you don't know if its a straight, two pair, or just A9 or something and you're letting the villain bluff you off (or catch a 2nd pair) if he doesn't already have you beat. As played I would have folded as well.
