If critics and competitors can't match your results, they will often denigrate the way you achieve them. Fast, intuitive types are called lazy. Dedicated burners of the midnight oil are called obsessed. And while it's obviously not a bad idea to hear and consider the opinions of others, you should be suspicious when these criticisms emerge right on the heels of success.
Garry KasparovA very strong player can manage and can just know how to manage a thousand positions. I get it; it's a very arbitrary number. So then you have the world champion who could do more. But, again, any increase in numbers creates, sort of, a new level of playing. And then you go to the very top, and the difference is so minimal, but it does exist. So even a few players who never became world champion, like Vassily Ivanchuk, for instance, I think they belong to the same category.
