Flop play with a big draw.

I feel I have no chance of making either opponent fold on this flop. I was uncertain how to play my draw, should I be capping this flop for value? sb opens light but likes to go to showdown. I don't have stats on UTG, but my player notes show he likes to limp in early position with big pairs, and then go crazy on the flop.
