MP1 is the same guy from the AKs post, CO is an utter maniac. TO me the MP1 played this exactly like a draaw, and I didn't think that in this situation and this pot was the kind for him to make a move without having me beat. I wouldn't make this fold if I had the K [img]/images/graemlins/spade.gif[/img], was it a bad fold?
