Hallo,
Thanks for the welcome.
I've been using the nickname Berger for nearly 20 years. All my friends address me by that name (they nicknamed me in honor of the Formula 1 racer Gerhard Berger). But since I started with chess computers, and of course arrived at this great house, this nickname has created some confusion. Coincidentally in Germany there is a great chess computer technician whose last name is Berger. For this reason I think it would be best to use my real name, Gerardo, in this forum. At least I will sign all my posts with my real name, even if my username is "berger", to avoid confusing any user.
Well, I hope to contribute to the wiki with more information, apart from the pictures.
Gruß
Gerardo
