in the situation you described, i prefer c/c. antonio is aggressive, at least in live games, especially when he has position. his firing range on the river is too large not to call a reasonable size bet. given that you've never played him before, i would avoid making a blocking bet because that smells of weakness and you don't have enough of a read to know how to react if he reraises you. there are two golden rules here: (1) bet only if you know what to do if you get raised (2) small hand / small pot.
