by the way, i hope you realize in game 1, kasparov also played utmost beginners
level. He later complained a few years later that he had to do so much effort to
lose that first game and didn't manage to lose it despite that.

Kasparov was very upset about him doing so many poor shuffle moves and still
winning the game.
