Villan is a reg. Opens 55% and folds 66% vs 3-bet on the BTN over a small sample.

What is you opinion of an overbet strategy on the turn? His range isn't really caped though. I think he has 77,88, A7s,A8s and AJ in his range. I would like some advice on whats the best line and sizing would be the best in this spot.
