When you play someone who is loose and passive, you must be careful when they do show aggression esp. when out of position. At this point on the turn after betting 75% of the pot and investing 50% I call. That being said, I might have played it differently. I probably would have made it $6.40 on the flop, but with a non aggressive player getting aggressive I might just call. With the turn bringing a J and it being checked I may check also. I know its weaker, but it will complete some draws or make a set, and we are still well behind any flopped set.
