What do you think about this hand? I was playing quite well in this session, but I don't think I did too well on this hand.
My read on this opponent was that he might be calling with a weak Ace. Maybe AT - AQ. He wasn't a strong player and I had been playing with him for a while.
If he had a full stack, I'm not sure how the hand would have gone. I might have been more cautious my bets might have been a bit less.

What's your opinion on the hand? Did I play really badly?
