Winter, Edward. "How Capablanca Became World Champion". Chesshistory.com. Retrieved 5 June 2008.. Winter cites: American Chess Bulletin (July–August 1920 issue) for Lasker's resignation of the title, the ACB's theory about Lasker's real motive and Havana's offer of $20,000; Amos Burn in The Field of 3 July 1920, the British Chess Magazine of August 1920 and other sources for protestations that Lasker had no right to nominate a successor; Amos Burn in The Field of 3 July 1920 and E.S. Tinsley in The Times (London) of 26 June 1920 for criticism of the conditions Lasker set for the defense of the title; American Chess Bulletin September–October 1920 for Lasker's and Capablanca's statements that Capablanca was the champion and Lasker the challenger, for Capablanca's statement that Lasker's contract with Rubinstein had contained a clause allowing him to abdicate in favor of Rubinstein, for Lasker's intention to resign the title if he beat Capablanca and his support for an international organization, preferably based in the Americas, to manage international chess. Winter says that before Lasker's abdication, some chess correspondents had been calling for Lasker to be stripped of the title.
