In 1996, she met 9 dan professional Yasutoshi Yasuda, with whom she kept in contact thanks to Shigeno Yuki, a friend who Diána considers as close as a sister. Diána wanted to be Yasuda's pupil, but this was not to be. Yasuda was very busy at that time. Both Yasuda and Yuki were a big influence on her.

She came 9th at the female equivalent of the World Amateur Go Championship in 1998, and was invited to Japan and Korea to study as an insei. Considering her young age, her family did not let her go. In March 2000, she won the European Youth Go Championship that was held in Sinaia. She came 2nd in the previous two years, and again in 2001. In the same year, even though she finished only joint 8th at the Hungarian Go Championship, winning the play-offs between the top 6, she became the Hungarian Go Champion. She was the first Hungarian invited to professional competitions in China, while still an amateur. Representing Europe, she entered three competitions in 2000, 2001, and 2002. Since 2001 she has continued studying Go, without a tutor. In 2001, she stayed in Japan for 1.5 months thanks to the sister and brother Kobayashi Chizu and Kobayashi Satoru. In 2003 she went to the Hungarian university, ELTE. She studied at the programming mathematician department, but she did not complete her course, because of an invitation from the KimWon Baduk Academy, thanks to Mr Eo Jong Soo. She got to know him at the World Championship held in Korea in 2003. She went to Korea in 2004 for 3 months, but then returned because she could not extend her visa. Until she was promoted to professional, from 2005 as an insei she was competing at the league in Seoul. In 2005, she studied at the Korean Myongji University and started teaching Go on-line.
