Former women's world champion Zhu Chen of China lost to the laptop computer "Star of Unisplendour" in Beijing earlier this week – the current standing in her human vs. machine chess match is 0-1.

The international grand master who became the second Chinese "queen of chess" by winning the world championship in Moscow in 2001, lost in her 54th turn after breaking the time limit. Playing black, Zhu established an advantage of owning one more pawn in the middle of the game. However, she made a fatal mistake in her 42nd move, allowing the computer overtake the lead.

The "Star of Unisplendour", whose software programmers are from some chess specialists and top players, was newly developed by a top Chinese IT company "Tsinghua Unisplendour Ltd." Zhu will play her second and final game with the computer on Saturday.
