Principles in middlegame over opening and endgame

Many chess players know a large variety of openings and understand well the pattern of the endgames but what happens in the middle? The difficulty of understanding the principles of middlegame play is perhaps best illustrated by the dearth of good chess books on the middle game. They can be counted on the fingers of one hand. Yet the middle game is a real challenge to the player. You have to make full orchestration of the chess game and you will have the chance to use all your pieces to carry out your ideas. All players will be grateful to the grandmasters who understand and play the middlegame lovely and with great effort of thinking for their masterly analysis of attack and defense in the middlegame.
