I'm afraid I haven't been following this newsgroup (or playing backgammon)
as much as I would like to over the last few months, I've been busy with
other things.  But recently I've noticed a large number of complaints
about all kinds of backgammon software -- I believe it could save us all a
significant amount of time if posters could in future please use the:

Official Software Complaint Form

  I want to make as much noise as possible and let the world know about
a gross miscarriage of justice concerning the following software (check
all that apply):

  [ ] FIBS
  [ ] Games Grid
  [ ] Jellyfish
  [ ] Netgammon
  [ ] Snowie
  [ ] TD-Gammon
  [ ] other (specify) ______________________

in the following manner (check all that apply):

  [ ] it has a biased random dice generator
      [ ] intentionally coded by the author to give "better" rolls to the
          computer to create the illusion of an superior backgammon
      [ ] unintentionally coded by the author because he/she is too
          incompetent to program one, even though satisfactory algorithms
          for generating psuedo-random sequences have been published for
  [ ] a conspiracy between the (specify) ___________ backgammon server(s)
      and (specify) _____________ bot operator(s) that gives the bot(s)
      "better" dice than me (I'm sure Elvis and the Kennedy assassination
      are involved here somewhere too, but I haven't discovered how yet);
  [ ] a conspiracy between the (specify) ___________ backgammon server(s)
      and (insert names of players who beat you) ________________ which
      gives them "better" dice than me;
      [ ] deliberately coded by the author to give weaker players higher
          rankings to encourage them to continue paying to play there;
  [ ] it maximises my duplication and minimises its own self-duplication to
      give the impression it rolls more "lucky" numbers than I do (this
      must be cheating, right?);
  [ ] it is horribly overpriced (I KNOW this because my 8th grade teacher
      once gave us a lesson on economics, it's all about the law of supply
      and something else, and the distributor(s) would sell lots more
      copies and the users would all be happy and we'd achieve world peace
      if it was cheaper, and I don't want to pay that much for it anyway);
      [ ] and it cheats too;

(Accusations of cheating only) I have the following proof (check all that

  [ ] I'm really good at backgammon, I can beat my grandmother and my
      little brother but the computer keeps winning against me, therefore
      it MUST be cheating;
  [ ] it rolled double-7 and escaped my 6-point prime;
  [ ] it rolled a miracle 4-3 which was one of only 6 rolls that allowed it
      to simultaneously complete its prime and hit the blot I left subject
      to only 3 direct shots; THEN I rolled 6-4 and 5-5 and danced twice in
      a row on a 3-point board -- there's no way that would happen with
      real dice, so it MUST be cheating;
  [ ] (the software in question) rolled 3 doubles in a row while bearing
      off -- this is clearly impossible, so it MUST be cheating;
  [ ] I've been playing for (specify) ___ years and never seen this before,
      therefore it MUST be cheating;

I haven't formalised my suspicions, presented a falsifiable hypothesis,
designed an experiment, gathered data and made reasonable conculsions
because I (check all that apply):

  [ ] don't know how;
  [ ] can't be bothered;
  [ ] already KNOW I'm right so there's no point doing any of that stuff;

In conclusion, I demand the following (check all that apply):

  [ ] The author publish the source code;
  [ ] The distributors reduce the price to (specify) $_.__; (commercial
      software only);
  [ ] I pirated the software in the first place, but it still cheats so
      it isn't worth what I paid for it, so SOMEBODY owes me (specify)
      $___,___.__ (commercial software only);
  [ ] Since the software is already free, the distributors should pay ME
      (insert amount) $___,___.__ to continue using their @!^$(* cheating
      software (free software only);
  [ ] I be compensated to the tune of (insert amount) $___,___,___.__
      for damages resulting from the above complaints;
  [ ] I don't really want anything except to stir up the same old
      arguments in  Has anybody else noticed this?
