GNUBG cheats and its previous sure, cause he gets almost impossible roles at the beginning of the game and in very weird situations. It was very interesting, it happens really often. For an example. I get good role and then in that role i have hit out a two men of gnubg. My two men was completely alone on position 12 (position 17 of gnubg) and position 13 (position 14 of gnubg), and other my ten men was blocking gnubg Home Board except on the position 4 (position 21 if we look from the direction of gnubg). What happens? It's Gnubg 's turn. Gnubg immediately gets double 4. So it has hit mine two men on my positions . Now I was out trying to get good role to come back again in the game, but i couldn't, cause only position 2 on my Home Board was free to go. I need double 2 to get out. So GNUBG won. That happens 5 to 6 time to me in 100 games i played against GNUBG, vice verse it happens only once to gnubg (it was in same bad position I have described in this post). Analysis: GNUBG won 5 or 6  times of 100 games with only possibility 1/36 to win, it had lost the game only once when it was same bad position (it has 1/36 possibility to lose).

Possible programmers conclusion  of GNUBG: "That was not cheating, it was a luck"
Definitely mine conclusion/question: "Very nice luck. Why I am not so lucky? Hmmmmmmm" Smiley))))))))))))))))))

P.S: I suggest that we should start to create database of BackGammon cheats . We should post moves of the whole particular game, picture snapshots of weird situations where bots has low possibility to win and at the end win cause of incredible joker and so many other things. What do you think? I think its worth while. Please make suggestions if you are interested in that.

gnubg does not cheat with the dice.  You can verify this by simply setting it to "manual dice", and playing a few matches by rolling a real pair of dice and entering the rolls yourself.  You'll still get clobbered.


This is a very old tired topic, as every newbie has the impression that gnubg cheats because it wins almost all the time, when the real reason it wins almost all the time is that it's just a much better player than the newbie.

BTW, if you're frustrated with gnubg winning too much, you can dial down it's playing level to "beginner" or "casual player".  This definitely makes it more fun for newbies.  Once you start beating it on a regular basis you can increase its level accordingly.

Do it for more than just a few and you'll see GnuBg get amazingly lucky dice from your own hands. ;O)

Choose the " manipulate dice" option from gnubg and set getting it the best rolls while you will get the worst ones then you will see how cheating will look like..you are going to loose every game in about may be 10-20 rolls.

Hm.... if you look in other newsgroups you will find a lot of complaints that bot x, y or z is undoubtedly cheating. All this complaints have several things in common:
  • the one complaining is a beginner, a casual player or a player who thinks is much better as he is in reality
  • a handful examples are presented that prove this, as if life play the dice are never crazy

Why world class player don't complain? Do they have a worse understanding of the game?

On my website I offer $1000 for one who proves that BGBlitz cheats. I get complaints about the dice regulary but.... it's somehow funny.... no one ever tried to earn the "easy money"...

So as a practical advice: reduce the playing strength or use weaker software. When you win constantly give it a try again. Would I recommend this? No, not at all. Get a kick in the butt and try to understand why you are loosing. Then you will get better and have better results against no bot opponents....
