Yet it has _seven_ pieces on the board. Tables work miracles, >but they don't make the impossible possible, yet... Nevertheless for position 1, after 1.Bd1 Kg8 2.h7+ Kxh7 3.h6 Kg8 4.h7+ Kxh7 5.h5 Kg8 6.h6 Kh8 7.h7 Kxh7 there are only _five_ chessmen on the board. So if he has tablebases enabled, then what _should_ the engines return? I don't have 5-men tablebases available, so I don't know. Is his analysis incorrect, or is he pointing out a bug or setup problem with Junior and Fritz? Also why do you get the impression that he implied that position two should be played perfectly? He does wonder this about position six which does have 5 chessmen. And what is the answer for position six?
