I checkmated, but both my opponent and I got 100% accuracy because the whole "opening", which contained blunders were book moves. Is this a bug or what?
Sort of. They were all moves played in games that the computer found in its database. Hence, they were "book" moves.
However, as you have pointed out, there is a problem.
I would say that the problem is with the book, not with the computer program that reads the book.
