>>I think you are missing an important point. Have you ever seen Rebel >>strangled in the last 25-30 GM games as we have seen in the dutch >>championship and at Dortmund? > >>Ed >It sure got strangled. Look at 21... e5?? and what happens after. That was a special "trapped piece" case (all programs do not understand) and has nothing to do with a) first block the position and then b) start a long prepared king attack. Not easy against Rebel which was my point. Evidence: the last 25-30 IM/GM games Rebel played. [ snip ] >I am just trying this Dortmund game Kramnik-Junior. After already 42 minutes on >a PIII-600E, Rebel still picks the terrible 8... c4, on its way to a strangled >and lost position. All programs are quite lousy against anti-computer >strategies, as a few test positions from this kind of games proved many times. After 8...c4 black is not lost at all. The real trouble started later in the game. >I don't think Uri missed the point. We have no proof of any sort of superiority >of a given program against human players. >Aegon: overall, Rebel scored best; in the last 2 years of Aegon, Kallisto and >Nimzo achieved the highest TPRs. Which proves nothing. Few games, erratic TPRs. >Israel: Rebel got the highest TPR, but without the last game lost by Shredder >due to operator's incompetence, Shredder has by far the highest TPR. Which >proves nothing again: few games. >The very highest TPR ever achieved by a micro corresponds to Junior in Dortmund: >2704 ELO, first GM norm ever. Few games, other programs didn't participate... >Etc., etc., etc. No few games. Each game contains 30-40 moves (positions) and 3-4 crucial positions that reveals important information. For Rebel that is 25 x 4 = about 100 crucial positions and hardly any stranglehold seen. Ed >As for subjective appreciations, everybody has one. Anand prefers Hiarcs, >Kasparov prefers Junior, others swear by Fritz, or Rebel, Genius, you name it. >Enrique
