live game 1 table tourney hand question

[orenthal]

down to final 3 in live tourney. i am SB with about T7700, button has about T6600, and BB has about T2700. money split is 60/30/10 . both other players are very close buddies that i know are both pretty good players, although button likes to gamble some and had been doing some pretty consistent preflop raises with low pocket pairs and then folding to bets on overcard flops. blinds are 300/600.

as i said, i am on SB and get A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/spade.gif[/img]. button raises 600, i raise to 3000. BB folds, button calls. flop comes 10 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/club.gif[/img]. i am first to act, where should i go from here?
