What is the best play ?

[Frenchie]

I had the following hand yesterday in a 2 tables SNG so we are in the money already but I am the short stack and I am really shooting for 1st. In the last few rounds, I have bet all-in a few times and got lucky when called by better hands. Would a raise of 500 or so and go all in on the flop be a better play ?
