      I am not sure if your comparison does meet the point. A 100 metre
      sprinter will never be able to compete at a pentathlon, computers
      can play at all time controls. Some days ago, Shredder has become
      Blitz world chess computer champion: who cares? It's not a very
      important title. What counts in Reykjavik are the normal games
      at slow time control. In my opinion the importance of blitz games
      is overestimated and slow games underestimated and that's a pity.

      Fully agreed: testing new versions of an engine is a very time
      consuming matter. In such cases blitz games can also be helpful
      to find out bugs.

      Thank you Keith.
