Is my HU play flawed at SNGs?

[DougI]

If I have my opponent 2 to 1 in stack size, I definitely will re-raise him all-in.
But if we are both about the same stack size, and a confrontation occurs like this, should I consider raising his bet to about half our stack size and see if the flop comes out innocent enough?
I usually want to end the HU play as quickly as possible. (Especially when the antes are at 150-300 or higher)
But I think I may be too confrontational and that I might be better re-raising him enough to see if he does go all-in or giving him the chance to back down.
If he does take the bait and goes all-in, then fine... its a possible coin-flip and I'm all-in also. But if he just calls my re-raise and I see an Ace on the flop, I have a chance to back down if I feel he was playing Ace rags against my PP.

What are your thoughts on this strategy?
