Good question, I have noticed this leak in my own play, calling down overpair all the way with 100bb if the pot is three bet preflop. I think a fold on the turn is better against a TAG or weak tight player who has a won at showdown of +55%. In todays more aggressive play it has become tougher to get away from TPTK and overpairs, as you are often in for about 14 blinds pre flop.
