Magnus Carlsen, Ian Nepomniachtchi square off for chess crown this week
Magnus Carlsen is sounding a little cocky -- and history suggests he may have a right to preen. There have been some 60 or so world championship matches (the numbers get a little fuzzy with the Split Crown Era of the late 1990s and early 2000s) since the mid-19th century, and there have been no real shocking upsets on the order of Buster Douglas knocking out Mike Tyson or the 1969 Mets winning the World Series.
