"Chess is not for the faint of heart," Steinitz once said. I agree 100%!
Chess players do not need pumped up muscles, they need a stable neuropsychic organization. How else can you resist the constant pressure that every nerve cell of the player experiences? I don’t always like this constant struggle with the stress that hangs over you, especially when you are wrong in a winning position. And in recent years, another "Problem" has been added - incredibly powerful computer engines that younger opponents skillfully use in preparation for the game. But when you win a beautiful game or use a theoretical novelty invented at home (albeit with the help of a computer), or defend a difficult hopeless position, how great it is! And at such moments you don’t think what chess is – it is science, art or sport. At times like these, they are just part of your life. (Vladimir Okhotnic)
