Then maybe it would be a good idea tp try to have 2/3 of your opponent's stack in by the turn opposed to going all in. This makes your opponent pot commited so if you make your draw, you can push, and expect a call, and you can fold if you miss your draw, saving you 1/3 of his stack. This bet probobly has the same chances of taking down the pot without a showdown as ppushing would too.

You probobly wont be able to do this often, and i wouldn't do it myself, but it seems like a better choice than moving in.
