Freedom is potential. The Grandmaster is potentially freer than the amateur. The amateur cannot make the best plays, the Grandmaster can. I don't think anyone in their right mind makes the worst move, even the amateur makes the best move for him, and he also becomes a less sophisticated kind of robot. But he does not have the ability of the Grandmaster to make the best objective and non-subjective play. As they say, "knowledge is power," and power provides more freedom than disability.
