The games were played with 30 minutes sudden death (blitz) time control; match was scheduled for 12 games. Genius used 3 MB for hashtables. The Palm Vx has been overclocked with AfterBurner - Tiger displays Speed index of 1.10 for this device. The hardware advantage for Genius in this match should have been somewhere around factor 4-6. An interesting follow-up IMHO to earlier matches against strong amateur programs (Yace,Comet) with same hardware difference that had much closer results and seemed to make sense. Also previous longer matches against some of the weaker WinBoard engines on Athlon1333 showed consistent results in the 2100-2200 rating region. In the match against Genius 4 Chess Tiger was without any chances though . Looking at the games themselve gave a similar impression. Even when Tiger managed to reach good positions sometimes it was always Genius who had the better answers, especially when it is about tactics, but its play also looked much sounder. In fact most of the time Tiger even displayed higher depths but the Genius search seemed to be much more efficient. SSDF lists Genius 4 with 85 Genius 4.0 DOS 486/50-66 MHz 2265 23 -23 900 49% 2270 Taking into account past callibrations of the rating level this is definitely very strong. But I would have expected Chess Tiger on the Palm to score better if it wants to reach 2100 SSDF level. I think Genius is clearly underrated on this hardware btw. Is Genius the very strongest program on the 486? Well possible. Or is it Tiger itself?! 62 Chess Tiger 11.8 Pentium 90 MHz 2382 43 -43 261 50% 2383 69 Genius 5.0 DOS Pentium 90 MHz 2329 18 -18 1558 47% 2348 In fact I assume that Genius profitted much less from the 486 to Pentium change, but that is guesswork. For callibration of the match results it would be really cool to test Chess Tiger itself on the 486 against its Palm brother, but unfortunately that's not possible :( Regards, Peter The games: [Event "Palm Tiger vs. Genius"] [Site "486DX50 vs. Palm Vx"] [Date "2002.05.02"] [Round "1"] [White "Chess Tiger 14.9"] [Black "Genius 4"] [Result "0-1"] [TimeControl "1800"] 1. d4 Nf6 2. c4 g6 3. g3 Bg7 4.
