I can play chess but it needs too much energy for too little fun in return, it is a killing game, it is cruel and some people take it as a measure for having a superior brain which adds to the killing ( virtual ). It needs visual skills and good pattern recognition and analytical skills and a good memory. However it is also boring. The enemy and all weapons and possible moves are known. Chess is often used as an ego and vanity booster. While you need some skills to be good at it it only makes use of some features of human abilities. A computer can do it too, or even better, so it isn't exactly an intelligence test. But being unintelligent doesn't help to master a simple play either. It is a bit like race driving. When you exercise you can get quite good, but you must have the will or drive to be really fast/good which is a natural predisposition. There are good vanity players, but their will to kill is powered by vanity. Some others are stone cold killers with a talent, some others border on psychopaths. In a sense Chess brings up bad things you might have. It isn't harmless to say the least. Elegant slaughter is still slaughter whatever it is called since it is the mind that moves the pieces.
