I want to repeat that my statement was not meant as an attack against Shredder.
I have used the word "excuse" because the argument has been used as an excuse
for other programs in the past, but I made it clear that I think that Shredder
does not need such an excuse.

Chess Tiger has not been optimized to play at a specific time controls level. It
has been optimized to play the best at all time controls.
I have been working for years with this idea in mind.
So the engine performs as well at any time controls, but on the other hand I
think the book written by Jeroen has been designed with longer time controls in
mind. That's another story.
