High Quality Content by WIKIPEDIA articles! The Pan-American Intercollegiate Team Chess Championship ("World Series of College Chess") is the foremost intercollegiate team chess championship in the Americas. Organized by the United States Chess Federation, the Pan-Am Intercollegiate is open to any team comprising four players and up to two alternates from the same post-secondary school (university, college, community college) in North America, Central America, South America, or the Caribbean. The Pan-Am began as such in 1946 (there had been earlier versions open to U.S. schools only), and is held annually, usually December 27–30. It has been held in the United States for virtually all of its history; however, it was hosted in Canada four times (1969, 1971, 1984, 1999). The current format is a six-round fixed-roster team Swiss-system tournament scored by team points. Sometimes the Pan-Am Intercollegiate is held as part of a larger event called the Pan-American Chess Championships comprising the Pan-Am Intercollegiate, Pan-Am Scholastic Team Championship, and Pan-Am Open (for any individual).
