It's getting harder to tell the difference between a computer and a human being--at least when it comes to playing chess. That was the result of an informal test at last month's Association for Computing Machinery See ACM.

In the test, Alex Fishbein, a computer science student at the University of Colorado University of Colorado may refer to:
  • University of Colorado at Boulder (flagship campus)
  • University of Colorado at Colorado Springs
  • University of Colorado at Denver and Health Sciences Center
  • University of Colorado system
 in Boulder and that state's chess champion, played simultaneous games against eight mystery players hidden behind screens. Three of his opponents were computer programs and five were human players. By the end of the evening, Fishbein had won five games, lost two and drawn one. But he was much less successful in identifying whether his opponent was a computer or a human player. He made the wrong choice five times.

The audience, made up largely of chess and computer experts, did somewhat better. Two people, including the author of a computer chess program not involved in the test, managed to make the right choice seven out of eight times. Many managed to spot two of the three computers.

"To tell the difference,' says Monroe Newborn of McGill University in Montreal, "you've got to be a real expert at both chess and computers.'

It is the largest of living birds; some males reach a height of 8 ft (244 cm) and weigh from 200 to 300 lb , "turned out to play most like a computer,' he says.
