That's not the point. As to tablebases it makes no difference whether TheKing runs under CM9- or Fritz-GUI.

That at least tests engine >strength alone, assuming opening book has no effect. You are right here but considering the great number of games we are playing, there is simply not enough time for that. And therefore, it's ok that Sedat is testing TheKing the other way round. > >On January 26, 2003 at 07:38:34, Kurt Utzinger wrote: > >>Hi Christopher >>TheKing [not using tablebases in it's thinking process] has the same handicap >>when playing under its own GUI.
