It's been a while since I analyzed a hand, but let me take a stab at this. I actually prefer that the hand histories don't tell us what your opponent had, and I made my judgements based solely on your initial post.

In hand #1, you are out of position from the start, and if you are going to play a pair that small only be looking for a set. UTG open raises for 4BB and then continues the betting on every street. You should know that you are behind. I don't like the reraise on the turn, the card is a blank and gives nothing to you or to him and everyone at the table knows this. I suggest reraising the flop if you really want to find out where you are at. If he rereraises, it's an obvious fold, plus your raise offers fold equity.

The second hand isn't played as poorly, however you are only 3 to 1 against any club in the deck and if he has an Ace, then you are only a 2 to 1 favorite. It's going to be a very difficult time getting any fold equity at these stakes here. However, you want people to call when they are behind, in the long run you will be paid off. Don't worry so much on this hand, it happens....
