Hi Ralf, >For even search depths: the ratio is (3w + 1)/(w + 3) >For odd search depths: the ratio is w*(w + 3)/(3w + 1) Do these 2 formula vary with depth? I mean is it true for depth=2,3 and depth = 9 ,10? >There is a pretty extreme odd-even effect. For e.g. w = 36 >we have 2.8 (even) and 12.9 (odd). > I'm quite surprised to know there is a big difference between odd and even ply. How do you explain this phenomenon? IMHO, it's the effect of Searchroot(). We don't have cutoff in Searchroot(). So,the ratio of Move()/Gen() is 36 at the first ply. Otherwise,I don't see any difference between ply . It's the same recursive function . Teerapong
