U.S. Open Chess Championship (1st 1900, no break, 118th 2017)

An open national chess championship that has been held in the United States in different cities annually since 1900 consecutively without any single year interruption, which makes it the longest running annual tournament in the world! Note: The U.S. Open Chess Championship (commonly known as U.S. Open) is not to confuse with the U.S. (Invational) Chess Championship.

Record winner of the U.S. Open is Pal Benko (8x), followed by Reuben Fine (7x).

Bobby Fischer won it 1957 as a teenager in Cleveland (on tie-break above Arthur Bisguier). First winner in 1900 (the first Western Chess Association Championship) at Excelsior, Minnesota was american chess master Louis Uedemann.

Non-US winners are rather rare: Boris Kostic, Carlos Torre Repetto, Arturo Pomar Salamanca, Daniel Yanofsky, Bent Larsen, Vlastimil Hort, Florin Gheorghiu, Boris Spassky, Viktor Korchnoi, Vladimir Akopian, Smbat Lputian, Eduardas Rozentalis, Evgeniy Najer, Vadim Milov, or Judit Polgar (plus some prominent émigrés such as Edward Lasker, Nicolas Rossolimo, Anatoly Lein, Leonid Shamkovich, Roman Dzindzichashvili, Lev Alburt, Boris Gulko or Dmitry Gurevich).

Through 1938, the tournaments were organized by the Western Chess Association (originally the Northwestern Chess Association) and its successor, the American Chess Federation (1934–1938). The United States Chess Federation (USCF) has run the tournament since 1939.

In the early years of the tournament, the number of entrants was small, the U.S. Open was a round robins event among whoever happened to show up! Play was conducted as with Preliminaries, Championship Finals, and Consolation Finals. It remained a round robin through a semi-invitational phase, but gradually introduced preliminary and final sections to accomodate more players.

An important innovation came in 1946 at Pittsburgh, as the Swiss System, advocated by Kenneth Harkness, was used for the first time to determine placement from the preliminary to the various final sections.

Starting in 1947, the Swiss system under the guidance of George Koltanwski took over the whole shebag, and subsequently the U.S. Open Chess Championship has been played always as an Open to accommodate a large number of players. Through some years, the tournament had 12 or 13 rounds and lasted nearly two weeks, this caused to be too expensive for many players, thus it is played today as most other Chess Open in 9 rounds in 9 days.

Tournament participation grew through the 1950s and 1960s. Milwaukee 1953 had 181 entrants, setting a new record for the tournament. Cleveland 1957 had 184 players, and San Francisco 1961 set another attendance record with 198 players. The 1963 Open at Chicago had 266 entries, making it the largest chess tournament held in the United States to that time.

Pasadena 1983's official count was 836 players, due to tthe participation of Viktor Korchnoi, it is still the best turnout in the history of the U.S. Open.

In the 2000s, the fields were over 400 to 500 entries, sometimes fringing a bit with many winners involved in one of those huge ties for first since the 1990's.

The cash prizes awarded were large for their time and added to the tournament's popularity, eg. in 1962, the entry fee was $20, with a first prize of $1000, second prize $500, third $300, fourth $200, fifth $100, sixth through tenth $50 and eleventh through fifteenth $25. Additional cash prizes were awarded to the top women, the top junior, and for the best scores in the Expert A, B, and C classes. The 2016 guaranteed prize fund was $40,000, with $8000 for first place.

In the 1983 U.S. Open in Pasadena, California, back when the US Open tournament was a 12 rounds, Viktor Korchnoi faced in the last six rounds of the event a bunch of the best players America then had to offer, winning the Open together with Larry Christiansen (Korchnoi first on tie-break at his first and only entry):


Round 5 Korchnoi beat IM Elliott Winslow

Round 6 Korchnoi beat IM Tim Taylor

Round 7 Korchnoi drew with GM Igor Ivanov

Round 8 Korchnoi beat GM John Fedorowicz

Round 9 Korchnoi drew with GM Joel Benjamin

Round 10 Korchnoi beat GM Dmitry Gurevich with White in a Nimzo-Indian in 22 moves

Round 11 Korchnoi drew with GM Larry Christiansen

Round 12 Korchnoi beat GM Yasser Seirawan

Trivia: U.S. Championship, Semi-Finals: Christiansen vs. Seirawan 8-6 (after speed play-off on Saturday 6th September 1997)
<< After their semi-final match ended deadlocked at 2-2 with a draw (classical chess) today, Yasser Seirawan and Larry Christiansen embarked on a marathon series of mini-matches: The G/25 match was tied, each player winning with White.
The same occurred in the G/15 match. No less than 4 G/5 matches were necessary before Christiansen finally overwhelmed Seirawan's Kalashnikov Sicilian. The two players played *11* total games today, not a one being drawn. >>

Korchnoi vs. Christiansen, U.S. Open at Pasadena in 1983:


Phony Benoni (chessgames screen name of David Moody , member of the Hall of Fame in the Michigan Chess Association) writes:

The game is exciting enough when you look at it, but the circumstances made it incredible. It was round 11 of a 12-round U.S. Open, Korchnoi and Christiansen were leading the field with 9 points, followed by three players with 8½.

Played in a small room, reserved for the top boards which had no space for spectator seating.

As the fight went on, more players kept crowding around the table and demonstration board, even standing on chairs to see what was going on. It was probably the most electric atmosphere I've even seen at a tournament.

None of the 8½s could win, so Korchnoi and Christiansen kept their lead and clinched a tie for first by both winning in the last round.
