Carlsen withdraws

Magnus Carlsen withdrew for the first time during a tournament before round four of the Sinquefield Cup in Saint Louis not mentioning a reason but quoting José Mourinho that if he would speak he would be in trouble. On the day before he had lost with White against 19-year-old Hans Moke Niemann whose earlier fair play bans on Chess.com fuel suspicions that Carlsen feels that Niemann wasn’t playing fair.
