We are late in the day of Day 1. We are 8 handed and blinds are 1k/1.5k/1.5k ante
We have 70K from a 40K starting stack
Villain 1 has 60K (he looks like what you would think of when someone says they play GTO, kind of nerdy looking pro), he is new to the table
Villain 2 is a splash young Asian player (He has been at the table for about 1.5 hours and has been a bit loose both pre and post flop)

Preflop: Hero has A 2 in MP
3 folds, Hero raises to 3K, 2 folds, Villain 1 calls OTB, Villain 2 calls in the Sb, bb calls
Flop: T 3 2
Villain 2 checks, BB checks, Hero checks, Villain 1 bets 3.5K, Villain 2 calls in sb, bb folds, Hero calls

Turn: Q
Villain 2 checks, hero checks, Villain 1 checks

River: K
Villain 2 checks, Hero bets 15K.....

Love it, hate it?

I'm a bit lost in this hand. I would be folding the flop to a slightly larger bet, but Villain 1 bet so small and I thought with back door hearts, I am getting a pretty good price.

I think played well. I might bet 18k instead as an extra tax on ips Tx combos.

I don't hate it-- you block AJ (which probably shouldn't have gotten here anyway); you're basically representing KT/QT-- but with two other people interested in the pot, I get the sense there's a reasonable chance one of them has the holding you're representing. That said, there's only two suited combos each of KT/QT available (KhTh and KcTc; QhTh and QdTd), which I would think makes it more likely this works. Villain 2's check is good for you since I'd expect from description that he's the one more likely to be in there with the offsuit Broadway combos, although Villain 1 might call KTo on the button.

4 ways I'd x/f the flop - x/c might be the worst option of the 3 imo. The runout is perfect to bluff at on the river, but your line doesn't really make much sense. Will Tx/88 type of hands fold here 3 way? I don't know its a 10k, I probably just give up in this spot as they should be thinking deep enough to understand what's going on here. Maybe in a low level tournament it's more profitable.

I'm on the plus side.

I would always call the flop bet with BDFD and small pair especially because we are last to act. If a 2 comes we are in great shape because nobody will see it coming. A heart or an A would also be very good.

Bluffing the river is good because we can have a lot of suited hands that got there (AKs/AJs/KJs) and even AKo/AQo might call that small flop bet. I don't think we can have KT/QT because personally I would bet the flop always with that.

Clearly we lose if Villain 1 has KT but that is just one hand they can have.

I think c/r flop would be a great play. As played it is a mandatory bluff, I don't think you get here with worse.

We are not last to act, Villain 1 is, and he's the one who bet the flop.

We are last to act on the flop after Villain 1 bets. I would likely not call the flop bet if there was somebody after us who could c/r.

Yes on future streets we are OOP and that isn't advantageous though we have relative position over Villain 2 (so we would be last to act again if Villain 1 bets the Turn or River), but if we improve on the Turn we may choose to c/r and if the Turn checks through we may be able to bluff the river.
