The king is a strong piece - use it ! - Rueben Fine


It cannot be too greatly emphasized that the most important role in pawn endings is played by the king. - Siegbert Tarrasch


In the ending the king is a powerful piece for assisting his own pawns, or stopping the adverse pawns.  -  Wilhelm Steinitz


The great mobility of the King forms one of the chief characteristics of all endgame strategy. In the middlegame the King is a mere 'super', in the endgame on the other hand - on of the 'principals'. We must therefore develop him, bring him nearer to the fighting line.  - Aaron Nimzowitsch


The king, which during the opening and middlegame stage is often a burden because it has to be defended, becomes in the endgame a very important and aggressive piece, and the beginner should realize this, and utilize his king as much as possible.  -  Jose Capablanca


The King plays a most important part in the endgame, and gains in power and activity as the number of pieces on the board diminishes. Acting in eight different directions, he becomes, instead of the weakest piece, one of the most formidable units.  -  Eugene Znosko-Borowski


The King is a fighting piece - use it!  -  Wilhelm Steinitz


Even the laziest king flees wildly in the face of double check.  - Aaron Nimzowitsch


In the middlegame, the king is merely an extra, but in the endgame, he is one of the star actors.  -  Aaron Nimzowitsch


If you study the classic examples of endgame play you will see how the king was brought up as soon as possible even though there seemed no particular hurry at the time.  -  Alexander Kotov


Begone! Ignorant and impudent knight, not even in chess can a King be taken. - (reputedly stated to one of his knights in 1110 after he was nearly captured by enemy forces)  -  King Louis VI
