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. The first 7 matches out of 12 ended in 7 consecutive draws. After 12 matches, the score was 6:6 and both players went to Rapid games. 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.

Migration of cloud service

Dear Chess friends,

we have an important announcement to make. After 6 years of using cloud services of our vendor SugarSync we decided it is time to move on to better, faster and more reliable. We have heard many unpleasant stories about slow downloading, breaks, corrupted files etc and contacted number of times the help desk of SugarSync. Their response was always like it is the users issue, they have slow internet or provider is blocking their services and other B.S. Despite numerous attempts to show them comparison of other services they were unable to help us. So it is time to move on. We have found better, faster, more reliable service to you. It is called Sync.com.
