First, the Gambit Tiger and Chess Tiger files are identical. These engines are not the same. So you do not have the Gambit Tiger times shown. Second, the 26 seconds on a PIII 800 is slightly suspicious to me since my Athlon TB 900 Mhz takes 27.3 seconds and I doubt that the PIII 800 is faster than that unless it's overclocked. Jim
