Jeroen's book is not a killerbook. If you call it this way I wonder why you
don't call other chess program's books "slaughterbooks" or "genocidbooks".

Not inserting killer lines in your own book is what I would call a fair
behaviour, but calling Jeroen's a "killerbook" is not.

It is overkill as anyway Tiger is playing without book in this match.

So what?
