Like a rabbit hypnotized by a python
Occasionally a position arises in the course of a game which cannot be evaluated on general principles, such as pawn weaknesses, open lines, better development, etc., since the state of equilibrium has been upset on several counts, rendering an exact weighing of the elements impossible. Attempting to calculate the variations doesn't always work, either. Imagine that White has six or seven different continuations, and Black five or six replies to each move; it's easy to see that no genius on earth could reach even the fourth move in his calculations. It is then that intuition or fantasy comes to the rescue: that's what has given the art of ches its most beautiful combinations, and allowed chessplayers the chance to experience the joy of creating.
It is not true to say that intuitive games were only played in the days of Morphy, Anderssen and Chigorin (as if now, in our era, everything were to be based totally on positional principles and rigorous calculation!): I remain convinced that, even in the games which received the brilliancy prizes at this tournament, not all of the variations were calculated to the end. Intuition has been and remains one of the cornerstones of chess creativity - of which we shall now see proof positive." David Bronstein,
