This situation has arisen on a few occasions for me now. This is how I've been playing it. Would you suggest otherwise?

I get dealt As early in the betting. I put in a moderate raise (4 - 6 xBB)
I catch one caller
A third person, short stacked, then raises all in.

When the betting returns to me I have simply been calling, hoping that the 1st caller will also stay in the hand, my intentions to beat them after the flop.

I wonder whether it is in my interests to reraise, keeping just the one player in. Not sure what the pay off is between taking smaller wins and having extra, richer stacks in the hand.
