Hi, my first post in here, hope its not boring.

Was new at the table, no read at him. I was trying to put villain on a hand. AQ or donkish flushdraw possible, i think. Was it right to fold, or should I have pushed? Its so hard to lay down kings...

I wanted to double my bet on the turn, but the Ace scared me.

Also, like I remember, he always instant called. This made me think he could be holding a set.
