  • Karjakin - Carlsen who is champion?

    Isn't this excited? The longest stalemate for period of more than 20 years. Sergey Karjakin (RUS) plays against Magnus Carlsen (NOR) and it is never ending story.

Forget about football, cricket or ice hockey, the whole world is now watching chess. It is east battling the west again like it was during the Cold war in Reykjavik, Iceland. The defending champion since 2013, Magnus Carlsen however doesn't have it easy.

It is called Sync.com.
