If you tell a computer to add up a column of figures, it gets the right answer
every time.

If you tell it to be creative about it, it gets the same creative answer every
time.

The typical chess engine doesn't have a lot of randomness built in.  If it
thinks the solution is X today, it thinks the same thing tomorrow.

So you tend to get the same game repeatedly if you play without books.

Furthermore, the opening position is a difficult position, since both sides are
very badly developed and starved for tempi.  Programs haven't typically handled
that position well.

Books are added to increase game diversity and give the programs a chance to
avoid looking stupid.

They also make human vs computer play more challenging.  Even a bad program can
play more like a human for the first few moves at least, and a human opponent
has to practice his/her opening preparation.
