For my first 20 years of chess tournaments (computer chess) there were *no*
prizes of any kind, other than the usual trophies.  "cooking" was still wide-
spread.  Now, for the commercial programmers, there are huge financial
incentives to do well at a computer chess event.  So cooking happens.  For the
amateurs, there is significant "self-pressure" to do as well as possible, and
one way to do this is to find a busted book line and attack it if possible.  It
is far easier to do this than to improve the engine dramatically in a short
period of time...

It boils down to 'effort' and 'return for effort'.  Cooking a book takes less
time and offers potentially greater returns.
