I thought, you would give perhaps one totally different point (after all, you also use very small TTs compared to other programs in your engine, if we can trust what we heard here - 32 or 64 Mb in Leiden this year). This first point, I don't get however. What has searching when needed to do with clearing of TTs? >2.

That indeed sounds funny :-) >5. Pondering > If an engine has pondered the wrong move, the TT will be overwritten with > positions that are either useless or have the wrong bound. Why should overwriting be a problem. Sure, it will be filled with a lot of useless info. Regards, Dieter
