Unlike other I do not think that the main advantage should be at longer time control. There are cases when it is the opposite and the program may find the win without tablebases at long time control when at blitz it may have problems to win won tablebases positions like KRP vs KR. I have no proof for it but I think that the main advantage of tablebases when they are used in productive way is at blitz. I think that at long time control when programs are closer to play perfect without tablebases their value is smaller. Uri
