You know, i don't appreciate being told to shut up, even if it is sugar coated.
The thing that is not so good about that comparison is that placing one piece at a time in Pente is THE WHOLE GAME, while this rule in Backgammon is to say the least not very common. And the other thing about this backgammon rule is that it restricts what would otherwise be legal moves - only in those specific situations is it illegal, why?
