25nl confused on river

villain is 16/10/3 over 125. folded to 2/6 flop CB's and 2/4 turn CB's. hasn't raised a CB. he sees me as 28/24/6 with a large ATS. he has seen me overbet a river on a dry board w/o shodown where i could only rep FH's/air (hand is here: http://www.flopturnriver.com/pokerfo...eg-191570.html ). BB is a 32/1 fit or fold fish. in play i felt like making what i thought was a thinnish vbet, immediately after the hand (lol results oriented) i felt like bluffing big with my blocker attempting to fold out 44/KQ and mid-range flushes. (although i have already fired 3 overbetting the river vs him in the last 100 hands so he might get a bit weird about me doing that). now i don't know what i should have done. what's our river play?

Bet turn bigger. As played, b/f like $3.5. I wouldn't count on people folding sets or top 2 at 25NL and I don't think you should be bluffing in a spot that you can vbet.

Our hand looks like exactly what it is because you bet the turn smaller then you would if you had KK/QQ/KQ. The only credible hands you have IMO are AhA and AhK or possibly AhX. With that said villains range is very weak too to have not raised your turn bet. I think you should just bet like 9$ and hope to get called.

More on turn for value, as played b/f rvr $4.50.

Villain's flop and turn play is odd given the mono flop and the fact you have the Ah. Does villain call pre with JT with Jh? Difficult to see what villain wouldn't raise the flop or turn with if he had anything decent.

don't try to bluff this river with an overpair...
turn $4.75ish
as played river is close. Villain will never raise as a bluff but block doesn't seem appropriate here. What size does he call KJ? bet that big (this could be $9 as per icandy if he views you as capable of tripling dumb shit here). Or check-decide if you like typing 'soulread' in chat

Bet turn bigger and I'm betting river for value not a bluff. I don't know how 25NL plays these days but you seem to be trying to get a little fancy (maybe not). But I've been there and it shouldn't be necessary.
