how do you play these hands? (blind special)

[nath]

So I hate these situations. Pretty decent stacks, good hand in the small blind, against a similar stack. How do you play these that a)give you the best chance to win and b)let you get out the cheapest? I hate the results here, obviously, but I'm not sure if I played it wrong or not. (I could give up the flop, I suppose, but it's just as likely to have hit me, so I bet.)

(from a PS $22 180-man SnG. As an aside, has anyone else had troubles with the hand converter recently? I had to find a third mirror of the bisonbison converter before I found a page I could access.)
