World Computer Chess Championships 2008

Kasparov vs. Deep Blue

   On 9/28/2008 the 16’th World Computer Chess Championships began in Beijing, China. The IGCA has scheduled an eleven round accelerated swiss tournament format for the top  chess engines in the world to compete for the the title of World Computer Chess Champion 2008. The accelerated swiss structure strikes me as odd being that there are only ten competing chess programs.  The principle of a Swiss tournament is that each player will be pitted against another player who has done as well (or as poorly) as him or herself. The first round is seeded according to rating. Players who win receive a point, those who draw receive half a point and losers receive no points. Win, lose, or draw, all players proceed to the next round where winners are pitted against winners, losers are pitted against losers, and so on. In subsequent rounds, players face opponents with the same (or almost the same) score. No player is paired up against the same opponent twice however. This is where the organizers of the 16’th World Computer Chess Championships are going to run into trouble. With only ten competitors and eleven rounds, it will be impossible to follow a swiss format. The schedule of the chess events have been taken off the the IGCA website and I expect them to alter the pairings and tournament schedule. Obviously this should have been done before the tournament started.

   My criticism of the tournament structure aside, this event should, once again, demonstrate that computers are now playing much better chess than humans ever will. Case and point: When Viswanathan Anand faces off against Vladimir Kramnik in eleven days, it will be computer chess engines that will provide humans with the most definative analysis as to who won the championship and why. I doubt we will see any humans evaluating Rybka’s games with out the help of a chess engine.

   Speaking of Rybka… After five rounds the reigning 2007 champion is tied with Hiarcs at 4.5/5. The two leading engines have yet to play each other. Below is the cross-table and a nice game played by Rybka.

  1 2 3 4 5 6 7 8 9 1
1 Rybka       =   1 1 1 1  
2 Hiarcs       = 1     1 1 1
3 Junior       1   =   1 = 1
