The Doeberl Cup is the longest running weekend chess event in Australia. Since 1963 it has been held every year in Canberra, Australia. Grandmaster Ian Rogers holds the record for the most number of wins (either outright or on tie-break) with 12.
The Doeberl Cup was named after its primary sponsor, Erich Doeberl. The family tradition of sponsoring the tournament continues today with Rosemarie Doeberl providing support for her father's vision. In 2007 O2C was the major sponsor of the tournament and from 2008 has attained the rights to run the tournament.
An account of the first fifty years of the Doeberl Cup has been recorded in Bill Egan's book, "The Doeberl Cup: Fifty Years of Australian Chess History" As well as full coverage of the fifty years of the event, with many games and diagrams, the book includes a CD-ROM with a database of over six thousand collected Doeberl Cup games, and a searchable record of results for everyone who participated during the fifty years.
