A good point. Too many chess books are already "written down" for a
mass audience of idiots. Every so often some unknown pops up with such
a book - "Chess Puzzles for the Causal Player!" and other such rot,
trying to claim you'll be able to beat the local 500 Elo with a
minimum of work. Find an old Reinfeld pdf on the web for free, and
you'll learn more in an hour by going over classic games and puzzles
than you would from 40 hours of study of tripe like that.

These books for "average" or "casual" players are often written by
folks who have no business trying to teach you chess.
