According to this site rules, that is what it says. If Fencer has changed the rules to the game, he has told no one - the rules page still lists the old one, and I think Fencer needs to inform users if any rule changes has taken place.
.... the question of if this site rules are the same as the "Official" rules - well I'm sure that is a debate in all it's self..... (which as a mostly non-checkers player, I honestly don't know much about.)
