1000 FPP hand

[SGS]

In the 1000 FPP first round. Early stages of tourny, 55 left, 9 get seats, blinds at 25/59I have an average stack of 2300 and A7o on the button. One limper I decide to play my button and raise it to 200. SB calls and limper calls. SB has me covered.

FLOP- AA10

Checked to me and I bet 250, SB raises to 500, limper folds, I re-raise to 1000, he moves in. Only thing I know about SB is he said he already won a trip to aruba or wherever stars' wtp event is. And I saw him play one hand where he moved in PF w/ AK and AQ called him. So basically my read was he is pretty solid. What do u do when he moves in and what do u think of my play so far? Thanks in advance.
