2/5 with effective stacks of $500.

It is a day game with a bunch of regulars. Nothing crazy.

1 limper to me in the HJ with AA. I raise to 25. Only CO and BB call.

Flop ($75)
822r.

Checked to me, I bet 50, one caller.

Turn ($175)
Ace

We each have about $425 left.

Checked to me, I check.

My reasoning here is:

If he has something that I would 'miss value' from, like 88 or A2, then I will be getting a lot of value by overraising his river bet. We will probably be getting it all-in regardless of whether or not I had bet the turn.

If he's behind with something like 66, he wouldn't have called a turn bet anyway and has a chance to catch up and make a ton more (big implied odds on a long shot).

And if he has something like 66 or 99 and would have folded the turn or 3 streets of value, then my weakness shown on the turn will probably get me extra money when he calls the river as a bluff catcher.

And some opponents might have folded low pairs to a turn bet but turn them into a bluff on the river since I checked the Ace. They'll try to use it as a scare card to get me off something like TT.

What do you think?

Your thought process isn't bad here, but I bet solely because if you don't it's damn near impossible to play for stacks. Go for the home run. U might get a smallish river bet called by a hand that catches a pair on the river, but that's not what I play for.
Btw, any type of villain description/hero image would be helpful/vital.

Line looks good to me.

Given old day regs, I think it's the type of situation where your not getting value unless someone spikes a smaller boat on the river.

check, if he checked behind which i assume he did just best big on the river

Really? vs old man day nits I'm betting small OTR

Induces a raise from 2x and smaller boats. Value from small PPs.

just bet i think

I like it. I also think most small-mid pairs are going to fold to a 1/2 PSB when the Ace hits.

good line, bet 70 otr

I'm betting since I want to play for stacks on the off-chance he wants to pay me.

I think against a day reg when you check back turn you can actually look strong or give off that you have showdown value as the A on the turn is a good card for us to double barrel as pfr...I like betting turn, try to get stacks in

Obviously it's very villain-dependent - but as a general rule in these situations, I don't mind the check-back to be honest. True, it reduces the chance of getting the guy's entire stack, but unless he has a hand specifically like A2 or 88, you're not getting his stack regardless. And if he -does- have that hand it will all go in on the river anyway, since he was just hoping to check-raise you on the turn.

Some villains won't call a turn bet, scared of having to face another bet on the river, but will call a half-pot bet on the river. If that was your read, than I like the play.

As described "daytime game with regs" I picture a bunch of 60+ yr old men.

AP check on the turn is great. Obv he doesn't have an ace and you checking on turn behind him is deceptive enough to make a daytime player think the A is a scare card for you.

Regardless of river I value bet 65 into pot forcing the daytime nit to sigh call

yeah checking the turn is fine here

if the turn was a jack I would barrel here again

+1, you are looking to get one more big bet on the river

The line is fine, the thought process is fine. I check it too and bomb 4/5 or 3/4 the river, maybe pot it sometimes.

Bet 50 again ott or even smaller like 35. Ppl then bet 75 ish otr if he doesn't raise over ur turn bet or lead river
