I may play some exhibition games so I don't want to quit the game of chess completely. I just decided and it's a firm decision not to play competitive chess anymore.
After that, Kasparov stepped back from chess which is, and I want this to be clear, not good for chess in general at all. As a whole, the current situation in the chess world leaves a lot to be desired.
The chess-board is the world, the pieces are the phenomena of the universe, the rules of the game are what we call the laws of Nature. The player on the other side is hidden from us.
I haven't played a chess match for several decades. At one point I lost most of my chess games. Then I realized many of my competitors were memorizing the best moves and I was unwilling to do this.
