I will go against the grain and tell you that altough you did go broke in a situation that warranted it, your whole line was pretty much weak/FPS/crappy.
PF is fine, he could be raising with all sorts of stuff and I don't like 3-betting AQ preflop because you are folding worse hands almost never, while you're getting played back at a lot. Againt very agressive opponents, maybe, but this is 50NL.
Flop is a definitive bet in order to induce a call (people just love to pick apart c-bets). C/R is not very good since we are giving away the strength of our hands the times we do not c-bet a good hand and it induces a bluff, wich is not very, very good since our hand becomes face up once we do raise. Also, you min c/r wich is silly: raise more or don't if you want to play for stacks.
Also, if we get raised on our flop c-bet, we know villain has something and probably something big unless he has been raising you c-bets with ATC.
Turn check/call is disastrous. Bet here because you're getting raised by a worse Q never making the hand a lot easier to play afterwards, while a hand such as TT or KK won't chance a bet, meaning you lose value. I like bet fold, but really, who plays b/f here after c/r the flop ? No one.
Leading the river is really, really, really, REALLY like burning money here after c/r and c/c all the way since there's no way in hell a worse hand will call (apart from a Q, but would he raise KQ ?) while better hands will put us AI and we are committed to the pot. C/c anything reasonable to induce a bluff from KK, AA, TT or AJ.
