I mailed Chessbase the question last week and they told me to try this experiment with Crafty as prove that it is decision of the engine alone what to do with hash tables: Take the second move of a position and let Crafty calculate some time. Then clip the analysis with search info from the search window to Notepad. Then go to the first move and let calculate for some time. Then go again to the second move and let calculate. Then clip analysis and compare with the first clip. Now the Crafty engine takes 25% less kN to find the same lines. I tried with the new 16.2 version from Chessbase download and it is right. And they say 16.2 is much stronger because Bob Hyatt corrected a problem in hash management. The Doctor? engine makes the same effect. Alois
