U.S. Chess Championship

The U.S. Chess Championship is an invitational tournament held to determine the United States chess champion.[1] Begun as a challenge match in 1845, the U.S. Championship has been decided by tournament play for most of its long history.[2] Since 1936, it has been held under the auspices of the U.S. Chess Federation. Until 1999, the event consisted of a round-robin tournament of varying size. From 1999 to 2006, the Championship was sponsored and organized by the Seattle Chess Foundation (later renamed America's Foundation for Chess [AF4C]) as a large Swiss system tournament. AF4C withdrew its sponsorship in 2007. The 2007 and 2008 events were held (again under the Swiss system) in Stillwater, Oklahoma, under the direction of Frank K. Berry. The Chess Club and Scholastic Center of Saint Louis in St. Louis has hosted the annual event since 2009.

Champions by acclamation 1845–1891

Years	Champion	Notes
1845–1857	Charles Stanley	Defeated Eugène Rousseau in a match in 1845
1857–1871	Paul Morphy	Won the first American Chess Congress in 1857
1871–1891	George Henry Mackenzie	Won the 2nd, 3rd and 5th American Chess Congress

Match Champions 1891–1935

George Henry Mackenzie died in April 1891 and, later that year, Max Judd proposed he, Jackson Showalter and S. Lipschütz contest a triangular match for the championship. Lipschütz withdrew so Judd and Showalter played a match which the latter won. A claim by Walter Penn Shipley that S. Lipschütz became US Champion as a result of being the top-scoring American at the Sixth American Chess Congress, New York 1889, is refuted in a biography of Lipschütz.[3] The following US Champions until 1909 were decided by matches.

	Year	Winner	Loser	Result	Notes
1	1891–92	Jackson Showalter	Max Judd	+7−4=3	The final game was delayed until January 1892 because Judd was ill.
2	1892	Samuel Lipschütz	Jackson Showalter	+7−1=7
3	1894	Jackson Showalter	Albert Hodges	+7−6=4	Prior to the last game the players agreed to extend the match. Many sources classify this as the first of two matches instead of one extended match.
4	1894	Albert Hodges	Jackson Showalter	+5−3=1	Can be considered a match extension or a new match.
5	1895	Jackson Showalter	S. Lipschütz	+7−4=3
6	1896	Jackson Showalter	Emil Kemény	+7−4=4
7	1896	Jackson Showalter	John Barry	+7−2=4
8	1897	Harry Pillsbury	Jackson Showalter	+10−7=3	Pillsbury added to the conditions of the match : "... even if I should win, I shall leave Showalter the possession of his championship title".[4]
9	1898	Harry Pillsbury	Jackson Showalter	+7−2=2	Contrary to the 1897 match, the title of U.S. champion was clearly at stake in 1898.[5]
10	1909	Frank Marshall	Jackson Showalter	+7−2=3	Title reverted to Showalter after Pillsbury's death in 1906.
11	1923	Frank Marshall	Edward Lasker	+5−4=9	Marshall declined to play in the invitational tournament that began in 1936.

6. In an objectively drawn endgame against Arnold Denker, the flag on Reshevsky's clock fell, which should have resulted in his losing on time. The tournament director Walter Stephens, who was standing behind the clock, flipped it around and, looking at Reshevsky's side of the clock (which he mistakenly thought was Denker's), announced "Denker forfeits!" He refused to correct his error, explaining, "Does Kenesaw Mountain Landis reverse himself?" William Lombardy and David Daniels, U.S. Championship Chess, David McKay, 1975, p. 22. ISBN 0-679-13042-X.
