My friend John just called me giving me a surprising news, Nimzo 8 just finished winning the 2nd game in a row using 2 hours /40 moves, whereas it didn't win a single game using G\60 after 9 games. >Pichard. > >>I do not think that having p3-800 can compensate for the difference in nps. >> >>It means that if there is a problem with the ssdf results of nimzo then your >>results suggest that the problem is different than the case that nimzo earns >>more from slower time control on the same hardware. >> >> >>The only possible problem that I can think of except the possible case that >>Nimzo earns more nodes per second from faster hardware is the case when the >>meaning of nps in faster hardware is not the same and Nimzo can see with the >>same number of nps more if it has faster hardware when it is the opposite for >>Junior. >> >>It is hard to check it for Junior because Junior do different jumps at different >>time controls and it may jump from iteration 14 to 16 using hardware A when it >>jumps from depth 15 to 17 using hardware B. >>I do not know if it is possible to translate a time control for Junior with >>hardware A to another time control with hardware B in order to force Junior to >>do the same jumps. >> >>Uri
