The Sankei pro-ama tournament

The Sankei pro-ama tournament (産経プロ・アマトーナメント) is a yearly go tournament organised by Kansai Ki-in in Osaka and sponsored by Sankei Shinbun. The first edition was held in 2005. In separate preliminaries pros and amateurs earn a place in the main tournament. The first round of the main tournament consists of 16 pro-ama games. Twelve of the amateurs and ten of the pros are selected via the preliminaries, the rest by recommendation.

Komi is 6.5, but in pro-ama games komi is 0 (and the amateur has black). A female amateur gets a 2-stone handicap against a pro.
