Preflop raise is questionable. This hand happened a while ago, but I think he was tight so I decided to raise this hand. The problem with this hand are villain's small bets.

I know I am beat but I just have to pay off. He was also bluffing previously with AQ unimproved OOP the same way as he played this hand with these small bets. Odds that I am getting are just too big to fold. Somehow I love villains who do these small bets because I often catch them bluffing when I can't fold bottom pair because I am getting 8 to 1 and somehow I hate them because I have to pay them off when they do have a hand. I probably more love them than hate them.

What do you think about that hand? Also, do you love or hate those guys?
