Is there a stop to Internet Backgammon cheaters?

flagoff....you are the one who lacks a brain if you expect us to buy your b.s.

I gave you a vote on your analysis. However I may have not made my point clear.  The probability of you opponent rolling a 6 (1/6) or you and your opponent rolling the same number (1/6) is 1/3.  That's where I got 70% not 33%.  So I said to myself that playing against opponents that exceed the expected probabilities are likely to be cheating.  So don't play anyone who rolls a 6 or when both come-out rolls are equal (any number).  The are likely to be a cheater.

"The  double before the first roll" - I meant that before your opponent has his first 2 dice roll, he/she doubles (the doubling cube).  A good player knows when to double and when to not accept a double (based on the probability of a win - how far ahead or behind you are), so an initial double indicates a stupid player or a cheater - both of whom I prefer not to play.

And yes, sometime I win against a cheater because of good strategy - their strategy is mostly to run immediately (poorest strategy of all) rather than to set up a prime or near prime.

I agree about playing as a beginner - no fun in that so I stopped.

Another thing I suspect is their control of your roll.  Have you noticed sometime when you need a good roll, your dice roll for an extraordinary long time followed by a bad result?  When this happens, I quit - can't win anyway when my dice are being controlled.

This is is why I suspect that when the come out rolls are equal, that your die was flipped by your opponent because he/she did not like the result.

I recorded the first roll of my opponent for 2221 games.  The opponents rolled a 6  861 times or 39% of the time.

The probability of rolling a 6 is 16.7%

Here's my way of telling a potential cheat (play experts and make them roll first):

5. They double before their first foll.  (A win is insured for them)

New study results.  This time I counted (using a program I developed) their come out roll of a 6 or equal rolls.

The expected probability is 33% (1/6 + 1/6)

I got 242/344 or 70%

One more thing...try playing as a beginner, not an expert.  They tend not to use the cheat programs against beginners.

**********************************

Tony, while it's true that the probability of rolling a 6 WITH YOUR DIE (dice) ON THE FIRST ROLL is 16.7%, it's only true on the first roll. You're rolling only one die on the first roll. 

With 2 dice, the probability of rolling a 6 with either (or both) of the dice is ALMOST double that, not 1/6 + 1/6. Because of the double 6, it's only 11 out of 36, or 30.55%, not 33%. Actually, that favors your argument even more, since you claim that your opponents rolled sixes 70.3% of the time.

Also, a double before their first "foll" (roll) hardly ensures a win. Early or even initial doubles (which should be impossible) do NOT ensure a win. In fact, there are strategies to make the early double work against the opponent. Even if the other person uses a poor strategy, they could get lucky and beat you, if you get early doubles.

Backgammon is interesting to me because it's a combination of strategy and luck. With a good strategy, you can win better than 75% of the time, even with the cheaters, if any.

Finally, the idea of playing as a beginner is abhorrent. Why bother? It'd be too easy.

I don't mind losing.  I don't care if my opponent beats me fairly.  I just saw my opponent in a game roll a 1,2, then proceed to move his pieces and mine.  There is cheating going on, and I will take an earlier posters advice and go check out another backgammon program or website.  Those of you whose only response is to call names and accuse us of being immature need to really look at your own motivations for this behavior.
