I had just moved to this table and did not know what to make of this.

I cant imagine why he'd want to fold me out if he had a set or straight, would he do this with a weaker Ace ?

I've seen really bad players do this with KK - they can't let go of them and go crazy. but I don't know if it's worth getting invovled here?

Any comments on how I played this ?
