Situation seems to happens to me all the time. I try to make the pre-flop bet big enough that people holding low to mid pockets and suited connectors will lay them down, but invariably I seem to get a few calls. Flop comes something along the lines of 2, 6, 9, and now Im sitting with a decision on how much to bet in.

Without question I would always bet in this situation, but how much/how long do you want to hold on if you are getting calls after the flop against your decent bets....thats the million dollar question.
