I saw that and I immediately thought SCs. Consistent with both PF and flop play. The $70 turn, while it seemed weird to me at first glance, does work. If you were bluff-raising the weak flop bet, you'd be hard-pressed to call any bet. If you actually had a strong hand on the flop raise, you'd either call or raise that bet. (I don't think a set makes this play).

A villain CR on the turn would probably raise flags. Other than this bet, I think the only other option villian has on the turn is to check-call, and lead out the river.
