There is an important difference -- in the case of "X <=> X" at any depth X you always pit two _identical_ opponents against each other which is not true for "X <=> X+1". Insisting on more than one calibration match essentially assumes that the Black/White behaviour of the self-playing program (i.e., "Fritz 6" in this case) changes with iteration depth. This might indeed be possible but it is so unlikely that I did not deem it worthwhile the effort to test. The paragraph on "Engine Calibration" already says so. >Why would you believe >that the "8 <=> 9" ply results would vary from the "11 <=> 12" ply results? I did not believe it -- that is why I ran the experiment. =Ernst=
