If you take a huge PGN database and attempt to play moves with the same
frequency as they appear in the database, you will make blunders, just
like the people in the database did.

You can do a pretty good job of culling out blunders (and typographical
errors, which are even worse) if you are willing to limit the amount of
diversity present in your book.

It helps to have a PGN database that doesn't have a lot of duplicates in
it.

My book used to suck but now it is pretty good.
