hand #1
the check raise preflop was good. Its just like you said, trying to protect what you thought was the best hand.
But when he called your AI on the flop, I bet you would have been crapping yourself, I would have been with A-J.
I wouldnt have gone AI on the flop with A-J unless you had some read on him of course.

hand #2
I think your screwed on this hand, he probably had A-10s or maybe higher pocket pair. Still slight possibility he had A-K or something similiar, thought you were on low pocket pair and so decided to bluff you out.
Would have bet on flop. Wouldnt have called the river bet of $15.

hand #3
would have raised on flop with overpair and open ended. Made a good move by folding to his AI on turn though. Lots of people I know would have called that crap with overpair & open ended seeing as they put so much money in pot.

hand #4
Yea would have done the same with that bullet on the flop.

hand #5
He probably would have hit his queen (or had decent pocket pair). BTW, I would have bet on the flop here not checked, to see where I am in the hand.
