Tough one, because of your diamond draw, which is almost certainly good.

Be real easy if you had a real stack, you could smooth call, bet huge if you improve, and consider your options if you didn't.

Here, I think you have to push, just 'cause your stack is so tiny it's pointless to call, and folding is weak.

And then rebuy to $400 if you happen to lose.

P.S. Fold preflop.
