Dear Francois,

Thanks for your reaction on the Rebel book.

I am not entirely sure where I found this move, but if I am correct
it could have been a suggestion in one of the latest Informators, or
the New In Chess yearbooks.

Unfortunately I do not keep records of all the moves, where I got them
from! But it must have been a suggestion, which explains why you can't
find any games with this move.

As you might know, I use a lot of suggestions made by strong players
in Informator or NIC. IMO this leads to a better quality openingbook
than just taking moves from played games.

Best regards,
Jeroen Noomen
