An engine can calculate 7+ plies within *one* single second. Test results where the correct move quickly shows up between i.e. ply 4 and 6 (and maybe never again), are meaningless. The probability that a correct move is lost after 1 minute, is *much* smaller than after 1 or even 10 seconds. Check your results for it, to see how many wrong quick solutions they include. Your'e jsut wasting time when using 1 extra ply only. Many test positions are not good enough to guarantee "stable" results. - But it's your decision of course. Good that you mentioned it, so all the experienced people know that they can skip your results... (I guess CCC is not the place where such advice makes sense anymore :-)) because either people know it already anyway, and the others will insist on their wrong methods. The level of this group is incredibly sinking...) Thanks and good bye, M.Scheidl
