Yes, I know about the calibrations of the SSDF list (which produce too low
values for the programs on the older hardware IMHO) . My question was why it
should be better to play matches against Chessmaster4000 or Genius 1 instead of
Comet and Yace, the doubled question marks because I could think of none ;). I
don't want to produce an SSDF list myself ( which also would make no sense as
Chess Tiger 14.9 is already being tested by them).
