Villian 1 - UTG, TAG reg player, $1000 stack

Villain 2 - Loose Passive on tilt player who just lost 2 buyins - $ 500 stack

Hero - Good image, playing lots of hands at a passive table - $2000 stack

OTTH

Villain 1 opens to $20 UTG, Villain 2 calls, hero looks down at AsQh in MP and flats. I'd 3-bet some and flat some here, this TAG UTG range is extremely tight in my mind, he's playing less than 15% of hands. I decide to take a flop in position with a weak player in between us. Pot $75

Flop AcKs4h - We flop top pair and have underrepped our hand. Villain 1 continues for $40, Villain 2 calls, Hero elects to call. Pot $195

Turn Jd completing the rainbow - Villains both check to hero. First big decision point for me here. Either villain 1 is nutted and trying to get a c/r in on a weak villain 2 or an aggressive Hero. I felt it was too strong to check and decide to bet $110 to get value from A10 and KQ, especially from weak calls from villain 2. Villain 1 calls, Villain 2 folds. Pot $415

River Kc - Villain 1 thinks for a while and decides to lead for $375. I'm confused. I think villain would either bet or c/r all his strong hands on turn. Trying to figure out WTH takes this line. I decide it's either a trickily played boat or better (AK, KK, KJ, JJ) or he's trying to get me off of a chop since I didn't 3bet pre. I decide to call and villain shows AhJc for a turned and counterfeited two pair.

Thoughts? Is my river reasoning good here? He said after the hand he definitely should have c/raised the turn but decided to get tricky.
