tough spot.

preflop is def a call.

now on the flop I think you need to really find out where you are at in this hand so that you can get away from this hand.

Two really important factors play in this hand I think

a) preflop 3bettor could be on a isolation raise.
b) preflop 3bettor who leads on the flop is very aggressive postflop even though its 40 hands he is still on the agressive side.

I would checkraise the flop to see where you are at with this hand early, if you get 3betted on that flop from the 3bettor with 2 other callers in its very safe to say your behind and drawing to a runner runner.

on the turn I would check, whether the preflop raiser 3betted or not since K is another scarecard and does not improve your hand.

if 3bettor checks behind on turn I would lead the river, if he had bet the turn I would check/fold river knowing I was behind.

I think with the line you took it's a really tough fold on the river since you are getting 13.5:1 and pfr 3bettor has an aggression factor of 4 on the river which is extremly high meaning he's going to be betting a lot of hands here i.e. Axs.
