The US Open
The US Open is the country's national championship. Held since 1959, the tournament is one of the oldest continually running tournaments in North America. Currently held annually at the US Go Congress, the US Open welcomes all comers, regardless of playing strength, age, gender or nationality. The tournament is also used as the selection tournament to decide the AGA's representatives to the World Amateur Go Championship and the Korean Prime Minister's Cup.
The US Open was originally preceeded by the US Championship, which split into East Coast and West Coast tournaments; the winners would play to determine the national champion. When the US Go Congress became a national-scale event, the Open was held as a separate five-round tournament over the final weekend of the congress. In 1992, the US Open merged with the congress championship and became a six-round championship tournament stretching over the entire week.
