This is a tournament for new Korean professionals. 25 players are identified for a preliminary round. The players are put in some order (the mechanism is unclear to me), then the first 2 play each other. The winner plays the third player on the list, the winner of that match the fourth, and so on until 24 matches have been played. All players winning 2 or more games qualify for the knockout round, and the final player also qualifies if he wins his game.
These knockout round qualifiers are seeded (again, mechanism here is unclear to me) into a knockout tournament, with a best-of 3 final.
2005 sees the fourth Osram Cup.
