With a nod to Jack "Voigt-Kampff" Dekerdt, AGREED, there is no rule "requiring" anyone playing a Pirate to announce first.
I might suggest, firstly, we're arguing on the SAME SIDE, buddy, so quit biting me.
I'd just like to point out, however, that even though Pirates are seen in a negative light, you gotta admit they live by an Honour Code... Even the Highwayman, who used to call out "Stand and Deliver!" (where "stand" meant to halt, or stop moving), meant only to relieve the victim of possessions, not of their life...
So while it may be correct that "no rule exists" or announcement is "not required", it is implicit in the job description, in that sense.
Or as Adam Ant used to sing "Stand in ye dinner, your money or your wife" ;O) yep showing my age here lol
