And if you want to know how a program w/o legs performs, it's best to... test
the programs w/o legs. ;)

I agree that in order to get the best performance of the engine it's best to use
the book too, since - as you point out correctly - the engine was
developed/tuned with this particular book in mind.

Not everyone who owns chess engines, plays engine-engine matches though. ;)

For someone who uses an engine to analyze her games, this best performance of
the engine is not that important. In fact, if the particular player for example
only plays the Sicilian defense, she should test the engines with a book, which
contains only the Sicilian defense, in order to find out which engine is the
best to analyze _her_ games... (whether the program plays brilliantly in the
accepted queen-pawn gambit is not important to her)
