Nakamura's (sic) owes his 'bad boy' reputation as well as his support to his participation in internet chess, especially bullet chess where each player gets one minute thinking time per game. Internet chess has fostered Nakamura's will to win and aggression but has also led him to overstep the mark on occassion. He reacted to a series of internet losses to Australia's young IM Zhao Zong Yuan by black-listing Zhao, claiming that Zhao was only pretending to be an Australian player when he was actually a strong European grandmaster. (Nakamura felt obliged to apologise when he saw Zhao playing for Australia at the Turin Olympiad.)
Well, what can we say to this Naka fellow? Sucked in mate! Our thanks to Peter Hanna for this tip via his posts on Australia's most popular chess bulletin board, Chess Chat.
