Dear Chess Friends !

Today I watched some eng. Vs eng. games. And I was deeply surprised to see the
next games:

Do both Fritz engines have a hole in their books, or the problem is somewhere
deeper ?
I don’t believe that it makes any sense to send these games to ChessBase,
because they normally ignore any questions or remarks. That is why their Fritz
impresses less and less in the last years.
