A LOT OF PLAYERS use the analysis features for overnight analysis or for 10 minutes or more on one position. For that; games at 40/2 are a much better indicator of strength. 2nd point is that the user can never be sure that the program is or isn't optimized for the tournament book that comes with the program. Indeed in most cases it IS optimized by the programmer to fit the engine's style. Opening repertoires are part of the equation of a chess player. Computer programs are no different. -- Komputer Korner >>>>>Processor: AMD 200 MMX >>>>>Cache: 8 M >>>>>Total games:32 >>>>>Time control: 10 minutes >>>>>Book settings: Same openings played by both sides >>>>>Book: Fritz5 >>>>>Result: >>>>> >>>>>Hiarcs 6: 10 >>>>>Junior 5: 10 >>>>>Draws: 12 >>>>> >>>>>Just from these first results it is interesting to notice that when both sides >>>>>play the same opening (eliminating any randomness), playing strength seems to >>>>>even out incredibly.
