Both Hiarcs and Rebel played Ra6 with mate in 2 all within 1 second. Fritz, on the other hand, played Kd2 same as what you got. I couldn't tell you why Fritz didn't see Ra6, but it has been my experience with the above programs that Fritz ranks last in seeing comparable positions. By the way, I'm running Fritz with 131 MB HT on a K6 400 Mhz processor. Regards, Mel
