overpair raised on turn by good player deep...fold?

[tecate]

villain is emma peel on ub, a good 22/19ish player who doesn't always raise in position with good draws.
i'm sort of aggressive, 23/17 stats...built my stack from co vs btn 5bet 100bb aipf with 99 vs his AJs and getting called down by a fish with a set. fwiw i took a while to bet the turn.
