1.) Hand 1 you cannot call the flop minraise without felting this hand, it's all in or fold.

2.) Pretty much always fold, your set of aces is like the 300th nuts. If I could do it differently, I bet 21 on the flop, then ~42 on the turn and call a raise. Since you let him take control just fold.

3.) I raise pre, late position limps are so weak. And if I were going to overbet, I'd just push. Why would you leave him with $37? As played, it really looks like he has trash diamonds...maybe Ax. And if he's bad, QT. But it seems like he'd raise the flop with the diamonds out there.

4.) QQ+ and AK. JJ if he's been active.
