@thibault : I agree with the previous post by @lucila-solis, and would suggest that there be a link to the practice section of the site where these topics are discussed. Another option is to add a button that users can click when a game ends by such a rule which would explain in short detail, why the game ended in a win, loss, or draw.
FAQ's and advices when joining will not be read by people, who start a new thread before reading let's say one page of the existing threads.
Maybe, whenever the winning side has only one knight or one bishop, the text "White/Black wins" could be supplemented by a hyperlink "Why did I lose?", which directs to an explanation in the FAQ.
What about a little "why?" next to the sentence "White/Black is victorious" when the player who won seems to have no mating material? People will click on it and (hopefully) learn the rule
Thanks SargOn, I just thought there was no way one could still mate in this position (guess I suffered from acute brain failiure) and on some servers out there the rules are diffferent from what FIDE uses.
I also wanted to be sure about the rules on this site, because I actuallly like this place, the design and all is just so much cleaner and better than on other servers.
