Hi!
Flop is clear c/c and calldown on decent cards(low cards that is...K is a clear fold,also is Q and anything 8 or lower is clear call;J and T are the hard ones)
If river is a 9 then its a clear c/r since you will get called light by many pockets,Ahighs,...
Turn A has a small problem though. I think ppls ranges become polorised and that is especially on lower limits...by that I mean that he will often not bet again with like 7767 or even KK,...;but on the other hand he will bet with JT,...
So when you look at this polorised range do you really want to raise? Vs his Ax range you are somewhere in between(you beat A3,A4,A7,A8 and loose vs others so you are actually slightly behind since A3 is not as likely as AK for example and there are also sets!) but on the other hand he does have a lot fo bluffs but these have basically 0 equity vs you and will fold if raised,so its clear that you do not want to raise these but preffer to let him bluff. So In general I would say that Im not a big fan of your c/r since I dont think that you are a favourite vs a range that will continue and facing a 3bet on turn will get very expencive....I would just cc here(with AJ+ it should be a raise though)
River as play should be a fold after a raise. I mean you have basically the worst hand in your range and you dont beat 1 reasonable hand... all the reasons to fold.
