rod03801: Yeah, <AOL>me too</AOL>. Even in games with a large pool of players, like Hyper Backgammon, I play some people over and over again. Even with almost all the games I play being tournament games. I've played some players more than a dozen times (out of almost 700 games HB games). It would be quite strange that the more games you play against someone, the less it counts for BKR. After playing 14 times against someone, it no longer matters whether I win or lose? My BKR stays the same?

Besides, it won't solve the "problem". Someone willing to cheat to inflate his/her rating could as easily create another account, and drain BKR from that person. Which is more efficient in the current system anyway - after several loses, the BKR has dropped and less BKR can be gained.

I've been involved in on-line games since the early 1990s, and many years ago, I've come to the conclusion that implementing rules/procedures against cheating with multiple accounts aren't worth the trouble. New automated rules (like the proposed rating chance) will hurt legitimate players, while cheaters will work around them.

Ask yourself, how often does cheating happen visibly (if someone cheats to bring his rating from 400th position to 200th position, do we really care?). I don't get the impression it happens that often, and the few cases can probably dealt with manually.
