ChessCarpenter: Indeed such table bases are of noticable theoretical interest, and usually a good marketing argument, too. ;-) My opinon on such tables is, that they should stay away from valued games. Moreover, most games, wherein ever table bases could be successfully used, were already decided before that stage has been reached. Nevertheless having such tables could be of remarkable productive usability for answering questions of endgame theory. Thus the place for using them should be in post game analyses only.
