<font color="#CC3333">UTG raises to $1</font>, MP calls $1, <font color="#666666">1 fold</font>, Hero calls $1, <font color="#666666">1 fold</font>, <font color="#CC3333">BB raises to $4</font>, UTG calls $3, MP calls $3, Hero ?

UTG is a madman at the table. Rasing about 40% of the time pre-flop and calling many pre-flop raises only to check-fold the flop.
MP is running at 50%/8%.
No real data on on BB.

I don't have the odds against the small stacks but do have against the maniac. However, the chances of stacking him are not so good as he seems to fold.

On the other hand, I did catch him attempting a bluff on the turn earlier in the session.
