"Chess is a human activity which brings together the human brain and the competitive spirit. But it's a competition without blood. There are 64 squares, and there is no blood" ~ Kirsan Ilyumzhinov
Is this a reason why fundamentalist religious leaders hate chess?
(Hint: Current bloodbath in Middle East.)
Religious leaders are control freaks that doesn't allow things they don't understand and cannot control. Could it not also be a attempt to ban things just to ban them in order to keep up the illusion that they are above everyone else? May that be chess or anything really that doesn't include sitting on a rug praising false idols and misinterpret allegories.
See, I didn't have to use complicated words that few understand to make my point across.
