bottom set, what to do?

[fourgapper]

PP $100 buyin Pot Limit.

Hero has about $200, SB has $220. Hero dealt 3 /images/graemlins/heart.gif 3 /images/graemlins/spade.gif on button. Four limpers, Hero calls. Flop comes 3 /images/graemlins/club.gif 4 /images/graemlins/heart.gif 6 /images/graemlins/diamond.gif. MP bets $2, CO raises to $4, I pot it (about $30), SB raises pot limit, to about $75. All fold to Hero. What should Hero do? Hero knows nothing about these players, having just recently sat down.

I'd push, but I'm pretty aggressive.

It's hard to say with a unraised preflop he could have the straight, in which you're a 4:1 dog to hit a boat. Then again he could have a bigger set.
