IMO, a reraise on the turn is your best play. The BEST hand that you can put an opponent on is a set for the Button (who could have called the pre-flop raise with 99, 44 or 33 and played aggressive when he hit). You are ahead, with redraws to a better hand that may make you even more (if you hit the nut flush, with BB or UTG potentially playing KQd). By re-raising, you get 1-3 BB in the pot with a +EV. If the board pairs the river you can check it down (or bet and fold/call to a Button raise). I'd bet the seven after BB & UTG check, as I'd assume they'd bet a made higher straight (and I'd LOVE playing against them the rest of the day if they were still in the hand with 6x), and I'd try to get one more bet out of the Button's set (or TT, 88, A9).
