A chess player NEEDS to have a strong ego. A chess game is (in part) a battle of wills, a struggle between two personalities. A person with a fragile ego will not succeed in forcing his will on his opponent.
Having said that... it is also necessary to maintain a sense of reality and a degree of detachment. You cannot afford to confuse your own hopes and aspirations with the cold facts of the position in front of you.
I dream that i am strong in some field except chess. Yet, when i play chess in midst of battle i begin to develop a boasting ego about my ability. I begin to think i can take any pain during the game since i am such a strong man. This has resulted that i play only with myself during some phase of the game without thinking that my opponent is stronger. I forget that chess is a better between two mind. How to lower such ego? It is something to do with maturity or age? If that ego goes out of my body and mind, what type of person do you think i will end up becoming? Any opinion?
