I think you're letting the BB in for too cheap PF, especially with 50 antes. Other than that looks good.. scary board, good raise, made SB + BB make a mistake.. worst card in the deck for you on the turn..

maybe I raise a little more on the flop, to like 3600, try to protect the hand against those small, weird bets.. but if they're calling 2500 I guess they're calling 3600.
