hand 1: calling the turn is best by far. We have a shitty image, TP, FD and are in position. Call turn and let villain bluff into you again on the river.
hand 2: I would usually just check behind turn here but i dont hate 3 barrelling. Villain definitly has 8x or a FD and FD seems more likely. If he is a showdown muppet then im not continuing without improving after the flop.
