Games of Cho Chikun against O Meien

2002-12-12: winning the Oza.

O Meien was born in 1961 in Tapei. He is the older brother of Tei Meiko and Tei Meiki. In 1975 he moved to Japan and became an insei; two years later he became pro. He reached 9 dan in 1992.

He has won the Honinbo title twice: in 2000 by beating Cho Sonjin, and in 2001 against Cho U. In 2002 he lost that title to Kato Masao.

In the end of 2002 he took away the last major title Cho Chikun held: the Oza. It was a dramatic match where in game 2 Cho lost on time in a won position, see this detailed report. In the end of 2003 it was his turn to lose the Oza to Cho U.

O Meien sometimes plays the fuseki in a very unique and unorthodox style. One example is 2001-02-22 below.
