How I understand it is that the current rating system here is great for skill based games (Like Chess).
But when you start to get into more "luck" based games (which Backgammon is a little luck - and Battleboats will be more luck when it gets here) - you need to use a different rating system to be more fair - since the current rating system is good for skill games and not luck.
I do not know all the details on the FIBS rating system that is used on the beter backgammon game sites, but it would be a better rating system to use for Backgammon - and probable other more "luck" based games like Battleboats.
(peida) Kui Sa klõpsad mängija nimel, siis Lõppenud partiid - saad mängude nimekirja, milles on lõppenud partiisid. Siis klõpsa mängul - saad partiide nimekirja selles mängus. Nüüd klõpsates uuesti mängunimel, saad seda partiid näha ja analüüsida. (Servant) (näita kõiki vihjeid)
