This has been happening for over 10 years now, it will never be fixed. About 1 out of every 10 matches with ranks over 2100 you will encounter a cheat. This is what I do...
- Never play against "Guest" - they use Guest because they are blocked by so many players now.
- When you know they are cheating, add them to your "do not match" list.
3. Quit the game and never deal with that pathetic loser again.
Help improve the backgammon community by losing gracefully and never stall. The person you are playing is not responsible for the dice roles they get. If anyone stalls you follow the same steps above. If EVERYBODY does this the losers will only be playing each other in a very short time.
P.S. The dice are random, they act exactly like real dice even though sometimes the roles seem incredible. If you play enough with real dice you will realize this.
