My interpretation is "there was very little improvement in COMPUTER vs COMPUTER (sorry to shout) strength from Rebel6 to Rebel 9." Perhaps this is because the Author was concentrating on improving his COMPUTER vs HUMAN results, and preparing to pit his program against Grandmasters. All this conjecture would be clearer if both Rebel 10b and Rebel 10c had both appeared on SSDF (although I understand and accept why they're not on SSDF). Perhaps the results of these Rebel's are inaccurate due to Autoplayer problems (Ed?, Bertil?) 29 Rebel 8.0 Pentium 90 MHz 2438 18 -18 1435 55% 2403 30 Rebel 9.0 Pentium 90 MHz 2437 23 -23 890 47% 2458 31 Hiarcs 6.0 Pentium 90 MHz 2434 18 -18 1437 51% 2430 32 Genius 5.0 DOS Pentium 90 MHz 2431 18 -18 1558 47% 2450 33 Hiarcs 5.0 Pentium 90 MHz 2427 38 -36 363 59% 2362 34 MChess Pro 6.0 Pentium 90 MHz 2412 17 -17 1726 45% 2445 35 Genius 3.0 Pentium 90 MHz 2408 26 -25 785 61% 2328 36 Rebel 6.0 Pentium 90 MHz 2407 31 -30 540 60% 2335 36 MChess Pro 5.0 Pentium 90 MHz 2407 26 -25 769 63% 2315 38 Genius 4.0 DOS Pentium 90 MHz 2404 23 -23 944 60% 2335 39 Rebel 7.0 Pentium 90 MHz 2402 26 -25 759 61% 2319 Tina Long
