Yes, tuning for *any* finite number of test positions is wrong. Playing a big number of games against a wide variety of opponents is the way to go. It is painful, time-consuming and boring, but so far I haven't found any other way of testing which works. >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 do most of my testing on a PIV 2.4 GHz, and I never use less than 10 seconds/position when running my engine through ecmgcp. Version 0.4.6 solves 136/183 at 10 seconds. >* Does it makes sense to use a reall long timecontrol? >* I learnt that ecmgcp.epd is much more tactical as strategical. Definitely. It is a collection of combinations, nothing more. A purely tactical test suite. >Does someone >has other/ better positional/eval-tweaking advice? No testsuites? Other >testsuite, like lct2.epd, the comeplete ecm.epd ? The complete ecm.epd would be no better. All positions are tactical. LCT2 is great, but unfortunately I don't know any other suites of similar type and quality. Tord
