Hand 1: What are stack sizes there BTW? I think you need to put him to the decision on the turn rather giving him the opportunity to put you to the decision. I like leading out 1/2 pot or so because it will not give out much info about your hand and now he has to consider the large range of hands you may have (since you probably reraise with a larger range than QQ+ I'm assuming). As played, I call the turn. I can see your thought process though - a Queen may be your only real out.

Hand 2: You played one of those tricky hidden hands with high implied odds and actually hit it. I think you should follow through. This guy may have hit his set or have 78s or something.
