25NL - ATo on draw-heavy board

I seem to be on a bit of a posting spree in here. Thanks very much to everyone for the advice, it's all being read and thought about, I assure you :)

This hand's a bit weird 'cause I misread the pot size on the flop, and so that changed some things, but I'll post it anyway:

Villain is 24/4 with a 25% fold to cbet.

Preflop: Standard button raise. I think villain's limp/calling range is: {A6s+, A8o+, K8s+, K9o+, Q9s+, QTo+, JT, 22+}

Flop: Villain doesn't fold to cbets often, seems to call along if he has any piece, be it a set or a gutterball. As such I thought I'd bet big here, so went for $2 into $2.60. Only problem being, the pot was $3.60, not $2.60. Whoops. That mistake doesn't affect villain's calling range too much, which is: {22+, A9-AT, A7hh-A8hh, AJhh+, K8s+, K9o+, Q9s+, QTo+, JT} against which I've got 64% equity.

Turn: Seven of diamonds, when I bet again here I expect him to gold his missed pocket pairs a bunch. I sized the bet to be just a bit over half pot 'cause I thought it might look scary of I went from a small bet on the flop to a massive bet on the turn. Villain's continuing range is: {22, 77+, 9-AT, A7hh-A8hh, AJhh+, K8s+, K9o+, Q9s+, QTo+, JT} against which I've still got like 63% equity.

River: River's a really nasty card for me. A whole bunch of his draws are now straights, or now pairs that beat my T. While I can discount straights a bit since he doesn't bet, I still think he has way too many J's in his range for me to be able to profitably bet/fold here.

Looks perfectly fine to me. There's pretty much nothing in his range at this point except missed draws and Js or straights. Unless less he has some weak T you aren't getting value out of anything worse and could certainly be valuetowning yourself. Check back is fine, note what he called 2 streets with on such a drawy board and exploit him again.

definitely check back the river. so few worse hands in villains range are calling compared to the straights/two pairs that are calling

Zomfg uber standard

Well I'd actually bet a little more on the turn as played, $6 is good imo; he'll very likely still call with all the draw and worse Ts.
