Botvinnik-Markoff extension
Posted: 23 Apr 2008, 15:19I can't find place where this idea is described in details. Maybe someone can indicate me place where can I read about this extensions or even better tell me something about it. If I good remember it was published by Sergei in old CCC forum. Unfortunately I forgot to copy it 
and it is not available on his webpage.
