"Catharsis" 8B+ by Tomoko Ogawa

Björn Pohl - UKC 21/Oct/2012

Tomoko Ogawa has repeated Dai Koyamada's "Catharsis" at Shiobara, Japan, thereby becoming the first woman to repeat a confirmed 8B+.

In her blog, she says she has worked the problem on and off for three years. I will try to get in touch with Tomoko to hear what she has to say about this.
