30-60 Stars Fold TPGK to River CR? (vomit)

[Mad Genius1]

Hi guys. I'm new to the MHS LHE forum since I just started playing LHE. Here is a hand I played where I had a tough decision on the river. I think everything else is standard but let me know if I did anything wrong. FWIW I was fairly new to the table but opponent seemed very active and played a good number of pots.

Game is 9-handed. Villiam (UTG) limps, fold to me and I'm dealt KQo CO+1. I raise, all fold to villian who calls.

Flop is K56r, he checks, I bet, he checkraises, I 3-bet, he calls.

Turn is T, he checks, I bet, he calls.

River 4, he checks, I bet, he raises. Pot is $642. Call or fold?
