Your check/call on the flop and turn just screams that youve got a king. Propably should of raised him on the turn, thats the way your gonna get maximum value IMO.
I mean imagine if you was this guy nd youve seen ur opponent check/call the flop and river..theres no draws out there, youve gotta put him on slow-playing a monster.

And i dont know why you check/called the river..i cant see why you didnt raise?!? betting out or at least raising him would surely make more money in the long run. You cant think ur beat here can you?
