Playing chess has many aspects that can be useful in everyday situations like planning, concentration and combinations. You learn to win but also to lose and to be creative.
In chess the most unbelievable thing for me is that it's a game for everybody: rich, poor, girl, boy, old, young. It's a fantastic game which can unite people and generations! It's a language which you'll find people "speak" in every country. If you reach a certain level you find a very rich world! Art, sport, logic, psychology, a battlefield, imagination, creativity not only in practical games but don't forget either how amazing a feeling it is to compose a study, for example (unfortunately that's not appreciated these days but it's a fantastic part of chess!).
Chess is thirty to forty percent psychology. You don't have this when you play a computer. I can't confuse it
One can say that in the last decades chess has become more of a sport than of a science. I see it from an artistic point of view.
It's very important not to put pressure on a child. Make sure that she/he feels that whatever happens it's not the end of the world. If they cry after a loss that's normal, as adults also hate to lose. If they win a game you should make them feel very proud but make sure they know the next game will be another challenge.
If you do your "homework" well you can be sure you'll feel more relaxed. Make sure you have a walk or rest before the game because the most important thing is to be focused during the game itself! If you get tired by preparation you won't have enough energy left for the whole game, and we all know that a single blunder can ruin all the work done beforehand!
I was labeled as a tricky player early on and have been regarded as tricky throughout my whole career. It was said that I was able to pull out tricks from nowhere.
I think it's very natural to get nervous. I've usually got concerns about a specific thing in the opening which might worry me. I have to be relaxed and balanced emotionally and then I can concentrate on the moves during the game. Then things will be ok.
India and China are improving by leaps and bounds and it will be their chess players who will lead the revolution of the XXI century.
