Rice Gambit, but he lost the case, despite being supported by witnesses who included U.S. champion Frank Marshall. This was apparently the first American case where chess matters made it to the courts. While seemingly frivolous, this case should be viewed from the perspective of Jaffe making much of his living from writing articles on chess for Jewish periodicals, so his professional reputation was at stake. Later career In 1916, Jaffe narrowly lost a match (+4 =4 -5) to David Janowski. Then in 1917–1918, he played a return match against Janowski, this time losing by a score of (+4 =4 -10). In 1918, Jaffe tied for 3rd-5th at Rye Beach, New York (Abraham Kupchik won). In 1922, he took 2nd, behind Edward Lasker, in New York (CCI). In 1925, he took 3rd in Cedar Point, Ohio (Kupchik won). In 1926, he tied for 4-5th at Chicago (Marshall won). In 1926, he took 2nd, behind Kupchik, at New York (Quadrangular). In 1927, Jaffe sent a cable from New York to Alexander Alekhine in Buenos Aires, where Alekhine was playing José Raúl Capablanca in the World Championship match. The cable contained Jaffe's analysis of a new variation in the Queen's Gambit, which Alekhine is thought to have used in the match. The victorious Alekhine, upon returning to New York, played a two-game match against Jaffe at the Waldorf-Astoria Hotel, without financial remuneration, as a favor to Jaffe, and won both games. Later years, writings Jaffe then left most competitive chess for a decade, except for occasional forays into Metropolitan League play in the mid-1930s, where he defeated a young (but already very strong) Reuben Fine in 1934. Jaffe lost a 1930 match at New York to Isaac Kashdan by 0–3; Kashdan was the top player in the United States at this time. Jaffe wrote Jaffe's Chess Primer in 1937 (published by Parnassus). His health was in decline by this stage. Jaffe also published several works in Yiddish. His return to chess in later life was chronicled by the writer and chess master Alfred Kreymborg in the short story Chess Reclaims a Devotee. Jaffe did qualify for the finals at the 1938 U.S. Open Chess Championship at Boston, where he finished tied 8-9th with 4/11, as Al Horowitz won. Jaffe's final tournament was the 1939 U.S. Open Chess Championship at New York, where he qualified for the finals, but lost all 11 of
