IGS history: 1-kyu account of Cho Chikun, 9p
Cho Chikun, 9-dan had several accounts on IGS, including 1-kyu account "mosh".
So, it's not a big suprise that "mosh" beat lot of top IGS players.
Here is the game Cho played with GURA (Ogaki Yusaku, 9p)
Ogaki overplayed in fuseki (Black 30 must connect at C7) and got crushed quickly.
