vic: Thanks Vic. It's very interesting to know we can see the Dutch Championship to the life. For me it's an important innovation and can be helpful to players in some countries like Portugal. In my country there're classic (portuguese) checkers and international checkers, but there is only one international checkers tournament for year. Many few players play this game and with innovations like that, maybe this situation can change. I'm going put those links in some portuguese checkers blogs.

Like you said, the important is the notation :)
