Final Pot: $5.20

I seem to get into a lot of situations like this, where the bet is small enough that I have odds enough to chase things like gutshots (and on the turn I could also get another jack). They never seem to pan out though.. and I end up losing a fair chunk of change in the end. So, I guess I just want to know whether I am right in approaching the hand this way, or if there is something I'm missing here... I have been on a long losing streak lately at this level, and I think a lot of it seems to come from the fact that opponents often bet very small relative to the pot and I end up chasing because I seem to have odds.
