Yeah, but everyone has capped his range. IP checked back a wet board 3 way and OOP checked twice to us. Again, I think 275 was overkill to accomplish what our range wants to accomplish, but betting seems quite safe here. As for being capped, I see hero having plenty of kings (KQ seems to be a fairly standard check on the flop, maybe AK and AA are sometimes checked as well), QQ, and potentially some flush draws.
