How many versions are the same engine in Fritz? i don't see much difference between the evaluation of genius 3 to genius 6 i don't see much difference between the evaluation of fritz 5.16 to fritz6 i do see clear search changes in nearly every program, though in rebel they seem very slightly after rebel8 was out. i don't see much difference in eval between rebel 8, rebel 9 and rebel 10 either. Clearly there was much difference in search and especially the standard search settings of rebel10c as downloadable from the rebel homepage to try it out it was having a kind of 'trick mode' standard turned on, which did not play very well on icc, but did solve to my amazement all kind of tricks in especially ECM testsets that no rebel solved before in decent times. It would be hard to ignore such a major standard trick setting and say nothing was changed. I FEEL positionally they didn't play stronger. At least at the positions i tested these programs didn't do different moves. Fritz5.32 however i found a bit different from 5.16 at deep searches. As if it was adding from a bit less deeper in the tree mobility, or better tuned piece square tables, i don't know. Changes were small seemingly though. Fritz6 is changed in this respect that it looks to me more like a super-nimzo version when talking about tuning, than a fritz5.32 did, though search in contradiction to nimzo looks very robust to me where nimzo's search looks like one alfabeta dependant bug. >This worries me, as I (and my Father) spend a large amount on what are sold as >New ewngines. >Thankyou, >Tina Long Well, some people are getting every year a new car though only they only seemingly change they sometimes get is a bit rounder lights, they hammered another area of the car a bit flatter. At a certain time some programmers have tuned their engines so well that it's hard to get additional rating points only out of the knowledge that's inside of the engine. I felt this clearly was the case with fritz5, rebel8, genius3, wchess, junior 4.6 Ok programmers start shooting or you might sell 10 copies less to this small group of dudes reading this CCC area.
