Hero ???


After his flop call I believe his range can be "narrowed" down to 44+,54s+ and combo draws like As7s. To call the pot-sized flop bet in a multiway pot he most definitely has some kind of hand he likes.

How do I proceed on the turn and river? What about my flop play? Especially how do I protect my hand against draws while avoiding to pay off sets?
