Checking to see another card is an abolsute no-no. Your chasing two cards, there are many others, especially many other over cards, what do you do when they hit??
How I play the flop is dictated by what I can represent. Did I flat call late preflop, limp call early pos, call on the back of a bet and a call? Each situation paints a picture of your hand. I would suggest that you dont think of having a small pair, even when you do hit, but what you can represent.
Ambiguous I know, but I think its more important to play what your opponents think you have not your chasing a two outer. And certainly never check a low flop. Low flops, come out firing BIG, take it down early or find out where you are.
But then again, what do i know
