Push or fold are your two flop options. You are a favorite against most of villain's probable range so pushing is most +EV.

I think calling is the most -EV thing you can do here because if you hit your draw villain is not going to immediately hand his stack over to you. He will most likely fold to any sign of aggressive once a scare card hits. You will also not get correct odds to call his turn pot-sized bet.

Get villain's money in the middle when he is an underdog should be your first consideration. If you don't win the hand, just spend your Sklansky bucks wisely.

If you play scared, you will never get real paid. One of the things you have to be able to do if you plan to eventually play $100, $200 and beyond is to not be afraid to risk your stack on a draw when you are the favorite to win. This also has the added bonus of giving bad players the impression that you like to gamboool it up
