From your description I assume button is raising any two 6 or higher or something like that. Maybe folding the occasional 96o. If thats the case then I like the preflop call fine so long as BB usually calls and almost never 3 bets.

Theres no strictly right play on the flop because its important to not be predictable here, but I'd be leading the majority of the time and 3betting most raises, checkraising some, and checkcalling occasionally.
