50 NL Turned Nut Flush, where to?

Ok this guy is a total station, he's running 51/0, bit more aggresive Post flop though, AF about 2.5 I think.

Noble Poker 0.25/0.50, hand converted by the iPoker Converter at Talking-Poker

BB ($51.40)
UTG Hero ($50.00)

Hero raises to 2.00, 2 folds, Button calls 2.00, 2 folds.
