analyse any kind of attack in face of this fact. The beginner
finds it hard to get used to this way of thinking. He prefers to
try to unravel a long string of variations and combinations, in
which he will mostly lose his bearings. Even stronger players
obstruct their own powers by refusing to see the value of judging
a position on general merits. They lose valuable time in thinking
out endless variations, to maintain positions which could be
proved valueless by general and logical deductions.
