A Grandmaster makes the best moves because they are based on what he wants the board to look like ten or twenty moves in the future. This doesn't require the calculation of countless twenty-move variations. He evaluates where his fortunes lie in the position and establishes objectives. Then he works out the step-by-step moves to accomplish those aims.
