Further controversy arose when, in 1912, Lasker's terms for a proposed match with Akiba Rubinstein included a clause that, if Lasker should resign the title after a date had been set for the match, Rubinstein should become world champion ("American Chess Bulletin", October 1913). When he resumed negotiations with Capablanca after World War I, Lasker insisted on a similar clause that if Lasker should resign the title after a date had been set for the match, Capablanca should become world champion. On 27 June 1920 Lasker abdicated in favor of Capablanca because of public criticisms of the terms for the match, naming Capablanca as his successor ("American Chess Bulletin", July August 1920). Some commentators questioned Lasker's right to name his successor ("British Chess Magazine", August 1920; "Rochester Democrat and Chronicle"); Amos Burn raised the same objection but welcomed Lasker's resignation of the title ("The Field", 3 July 1920). Capablanca argued that, if the champion abdicated, the title must go to the challenger as any other arrangement would be unfair to the challenger ("British Chess Magazine", October 1922). Nonetheless Lasker agreed to play a match against Capablanca in 1921, announcing that, if he won, he would resign the title so that younger masters could compete for it ("Dr Lasker and the Championship" in "American Chess Bulletin", September–October 1920). Capablanca won their 1921 match easily.
