Hi Tord! Thanks for answering I am affraid you are right ... I test most of the time a lot and make tiny steps. What timecontrol do you use for testing games? I think I need also more modern . The quality of faster hardware is automatically better than on my hardware on the same timecontrols. >>My questions: >>* Is 5 seconds a move a good timecontrol to test ecmgcp.epd ? > >You should use more, IMHO, especially considering your slow hardware.

I think 10 seconds on your hardware is about 20 seconds on my hardware. I will try to use a longer timecontrol for ecmgcp.epd too to see what happens. >>* Does it makes sense to use a reall long timecontrol? >>* I learnt that ecmgcp.epd is much more tactical as strategical. > >Definitely.

All positions are tactical. >LCT2 is great, but unfortunately I don't know any other suites of >similar type and quality. What timecontrol do you normally use to test this? Do you look also for each position to number of nodes searched. ply depth solution found?
