Hand 1: Fold. Fairly small bet to call compared to the pot, but you gotta fold here. One of them must have the straight, and they'll be betting out on the river. Even if it is a semi-bluff, are you willing to call if they follow through with a huge river bet?

Hand 2: Fold. Man would that piss me off.. AQ, AK, and two pair is out there: I would fold. Very tough one.

Hand 3: Call. He probably has you but it is worth calling the small bet. Who knows, maybe he is trying to buy it.

Hand 4: Call.

It seems like I lose a lot of money by calling too much with top pair.. Its a tough hand to play.
