Has it been revealed who helped Magnus Carlsen in preparing and during the World Chess Championship against Karjakin?
- GM Peter Heine Nielsen (no surprise as he was part of team Carlsen in WCC 2014)
- GM Laurent Fressinet (also no surprise as he was part of team Carlsen in WCC 2013 and WCC 2014)
- GM Maxime Vachier-Lagrave (quite a surprise as he is the current world's nr. 4)
- GM Nils Grandelius
- GM Jan Gustafsson (the tweet of RadioJan was not a joke)
- GM Samuel Shankland (a surprise to many, however it was revealed that he also helped for WCC 2014)
