In chess, knowledge is a very transient thing. It changes so fast that even a single mouse-slip sometimes changes the evaluation.
Viswanathan AnandPsychology plays a big part but I always say psychology will only be a differentiator when the players are of equal technical strength.
Viswanathan AnandIt's important, according to me, to train in small doses so as to not lose the joy of playing chess. I personally think too many coaching and training classes may take away a child's interest in the game itself. The essential thing to do is practise often and, in case of a doubt, to consult a trainer.
