Doctor Kibbitz says: "John W Donaldson has had more success playing the Black pieces. Very high percentage of draws might indicate fear to pursue aggressive play. Endgame play is very strong and is shoring up overall results. " |

Note: We regard any game of 48 moves or longer to be includable in endgame statistics.
Approximately one third of all chess games are decided in the endgame.
One can see, therefore, that endgame skills are of tremendous importance.
Yet, this is an area that is very often neglected by young players.
Success in the endgame demands familiarity with its own particular skill set; the
strategy and tactics of the opening and middlegame are out of place here.
Understanding the endgame's unique nature, and studying its mechanics,
will catapult the player forward to mastery over his or her peers. Without
this understanding, the greatest triumphs over the board are just not possible.
