You seriously need to get a hobby besides insulting GMs like Lein or the legendary Korchnoi, two of the great elder statesmen of chess. As for the latter, Korchnoi is 75 years old and still near the top 100 players in the world, still playing great chess.

Who are you to criticize his comments??? are you Korchnoi son???

and i was surprised and impressed that he had

enough stamina to continuously walk around

dozens of chessboards and play the way he did

(very strong!) for the amount of time it took. I

think he only lost one game in a field of up to

class a/expert level players.

Don't spend a lot of time trying to solve any one puzzle, but try hard to solve the hundreds and hundreds of puzzles. Their argument is that it is most important to get lots of correct examples into your mind.

Then, go back to the beginning and do the whole book again.

--Anatoly Lein

When we were growing up, I was fascinated by chess, reading and studying every chance I got. He seemed to have no interest in the game at all.

Then out of nowhere, in the mid-70s, he joined USCF and began playing correspondence chess. His goal was a simple one: get a higher correspondence rating than mine.

He accompished this in a couple of years--without using books at all--then stopped and hasn't played since.

Disgusting.
