Ending?
Why is ending needed? Many beginners think that good openings and tactics are the most important stage of play...Wrong!
Most of the highly theoretical openings such as the Dragon Sicilian result in an endgame with many imbalances. Without the proper endgame technique, playing a good game will be impossible. Many grandmasters win their games because of endgames. Master your endgame and you will quickly become a master from a beginner.
