$2/$4 blinds,
hero has KcQc
hero in bb, villain in sb. eff stacks $400
villain raises $12, hero 3bets to $40, villain --> $100, hero calls.

FLOP:
Td3d5c
villain bets $40 into $200, hero calls.

TURN:
5d
check check

RIVER:
Kd

Reads: villain has some 4b bluffs pre, can be overly aggro on scare cards.

My analysis:

On the turn, villain would be barrelling AdTx, Ad9x, QdJx etc hands QdTx as his 4bet bluff pre hands had he picked up fd with shallow spr.
He's just calling suited Ax diamonds pre probably so a turned flush is not super likely.

his value shoves for pot is probably Ad, maybe Qd? so how many Ad Qd hands actually check turn. not that many. QdTx? or AdTx? KKK? KKK for a boat of course, but I block that. I think AdA and QdQ(I am also blocking one Q) is going to bet bet bet most probably.

HENCE, on hindsight I shld have been better off calling?

THOUGHTS please guys! THANKS and feel free to share any of your thoughts!!! :D
