AQs out in the SB - how's the line

[vhuntd]

How's this line - i considered 3 betting preflop but i didn't think that it would knock anyone out and didn't want to do it out of the SB. Also, i wanted to try and disguise my hand.

Final Pot: 14.50 BB

my intention was to checkraise the pf raiser on the flop but someone led into him. Since the pf raiser didn't raise the flop i decided that he didn't have AA or KK. Maybe AK or a smaller pr. Onthe flop since i was closing the action and can't protect my hand i decided to just call and check raise the turn.
Turn is kinda a bad card but it was checked to the pf raiser who hesitated for like 2 seconds before betting. So i decided that he probably didn't have me beat and raised. River is an auto bet i'm assuming. How'd i do?
