Walter Montego: Problem with those games witch contains luck is that the system is made for chess. Because that system is made from statistics. It should be done to every game own, that it will be perfect. The hyper backgammon is the most problematic i think. There player with random moves can even won. It contains nearly pure luck if both think for while the maximum thought winrate should not be higher 75 percent or something like that.
For me this is pretty same. I do not play for rating. I play to win.
