[You're No Daisy]

This looks like a missed draw to me. I don't think the King hit him. I see a lot of players raising with their draws to protect their hand and get free card...which happened here. I think his bet on the river is probably a bluff. If he had a suited King, he probably would have bet the turn for value. His line make no sense. It's a ballsy (but good) call on your part. Sometimes you just have to go with your gut. Also, it lets the other people at the table (if they're paying attention) that you aren't backing down on the river and that they need a strong hand to make you fold. Take notes on this guy after the hand.
