This first hand is an AK hand that got completely out of control on the flop. I was fairly sure somone had two pair or maybe a straight, but I couldn't get away from it with the huge pot odds on a queen or an ace dropping. Is there anything I could have done to make this run a little more smoothly? Perhaps I shouldn't have reraised on the flop?

The second hand is one where I felt sure I was beaten, but didn't want to let go. Should the limp-raise have tipped me off that I was facing a QQ? I probably should have just gotten the heck out of there.

I think I played this third one right, but it was an annoying defeat. Is there anything I could have done differently?
