Games of Cho Chikun in the Agon-Kiriyama Cup
The Acom Cup changed sponsor in 1999 and became the Agon-Kiriyama Cup. The format did not change, and neither did the numbering of the installments. One of the interesting aspects is that 20 amateurs are invited to join in the preliminary rounds. The final is a 16 player knockout in which the major title holders are seeded.
This list is complete, but the game in 2001 versus Yoda seems dubious (although it comes from a reliable source). Neither Yoda nor Cho were in the final 16 that year.
