What do you do here?

Opponent is decent but nothing great. I don't really have any specific information on how he plays. What should you do here?

(1) Lead out more on the flop. Probably $35 to a pot-sized bet is more appropriate.

(2) He probably has A/images/graemlins/spade.gifA whatever, A/images/graemlins/spade.gifK whatever, a flush, a set of KK. He might even have AK no spade. I'd push here and cross my fingers.

(3) This post belongs in small-stakes.
