Nick of a player who showed up on KGS for 3 days (12-14 july) in July 2003 and won against some high dan players. Has beaten both breakfast (twice now) and DKiller72 on even and not lost a game otherwise (though he hasn't played tartrate).
He commented on his second defeat of breakfast in Japanese, and said he is a 7-dan amateur from Japan. You can find these comments translated and with lots of variations here.
Unfortunately, it looks like he isn't coming back to play against the new strong players.
