The laws of chess do not permit a free choice: you have to move whether you like it or not.
Emanuel LaskerOn a motif such as was indicated by Reti one cannot build the plan of a whole well contested game; it is too meagre, too thin, too puny for such an end. Reti's explanations, wherever they are concerned with an analysis which covers a few moves, are correct and praiseworthy. But when he abandons the foundations of analysis in order to draw too bold, too general a conclusion, his arguments prove to be mistaken.
Emanuel LaskerIf Steinitz continually took pains to discover combinations, the success or failure of his diligent search could not be explained by him as due to chance. Hence, he concluded that some characteristic, a quality of the given position, must exist that would indicate the success or the failure of the search before it was actually undertaken.
