In most cases they work. For this particular problem... they don't seem to. I followed the same procedure I usually do.... I outlined the procedure I used.. I was hoping someone could spot what I did wrong if anything. When I 'changed' engines.. I see the notice.. "initiating tablebases" I don't get it. I tried it before.. on Fritz 5.32, and it found it instantly. Oh well.. I'll keep playing with it. Thanks, CY
