  This doesn't have anything to do with Rankk, or online challenges in general, but since this is an audience of people who like games and challenges, I thought I would mention this.

  There is another challenge going on at the present time (from Nov 25-Dec 5) in Bonn Germany, between the world chess champion Vladimir Kramnik and a chess program called Deep Fritz 10. With one game to go, Deep Fritz 10 is leading Mr. Kramnick by 3-2, thus the best the world champion can hope to achieve at this point is a draw.

  Of course chess computers have beaten world champions and Grand Masters in the past, but I still find it amazing that computer chess has come this far. Also, what makes it even more amazing is that unlike some of the special chess computers of the past (i.e. IBM;s Deep Blue), Deep Fritz 10 is a computer program that anyone can purchase and install on their home machines. Deep Fritz 10 is for multi-processor machines, and Fritz 10 is for single CPU machines. (although I'm not sure, I think Deep Fritz 10 can still be installed on single processor machines). 

  Anyways, for those of you who do not play chess, I strongly urge you to learn the game. It is a game that anyone can easily learn in an hour or less, but can take a lifetime to master. (Of course most of us will never get anywhere near that point)

  Nice read...

  It always amazes me that a computer can "play chess", because it's such a complex game.

  I had the experience of playing Chinese chess on a small portable set. When I played it at level 1, it was possible to win the machine because presumably it was programmed to be on the defensive.

  But when I set the game at a higher level, the computer took longer to "think" and I don't remember winning any. It wasn't merely defending but it was also making attacking moves. But I was amazed that it could "anticipate" my moves.

  With a portable set, my hunch is that you could find a way to win the game and use the same strategy to always win i.e. it doesn't have the capability to learn from experience. But with Deep Blue and Fritz, it's a different ball game because they do "learn" as they play.

  Does Deep Fritz use Neural Nets ?

  Man vs Machine has usually meant Parallel vs Serial

    I really don't know what algorithm they use these days, but I am pretty sure it is not a neural network.  I think I did see that it can analyze 3 to 3.5 million moves per second.  It also uses a very large book opening, so it would seem to me that it would be the strongest during the opening and end game, and that the best chance a human player would have would be during the mid game.

    There are also a number of other programs that may be even stronger than Deep Fritz, namely Rybka, Junior 10, and Shredder, among others.  A list of the rankings are at:

    Another thing that I find interesting is that the programs are better chess players than the persons who programmed them.

    BTW, for comparison, Vladimir Kramnik's rating as of Oct 2006 is 2750

      A window on the motivation behind a lot  of programs in that ;-)
