good players without reading books

[marcedo]

there are some very good players who dont read books at all. they say that the books are not neccessary because the real secrets are not written down.
i dont understand how they come to that conclusion when they didnt read the book

but i believe some dont read books, but who can they be very good players?
i dont understand that.

everybody needs some theory to play. or is it a such a big feeling for the game, they dont need to read books?
