NEW YORK » In the "Jeopardy!" battle of man vs. machine, man and machine were neck-and-neck on Monday.

Human player Brad Rutter and the supercomputer named Watson ended an initial round tied at $5,000. The other challenger, human Ken Jennings, was far behind with $2,000.

Rutter (the show’s all-time money-winner with $3.25 million) and Jennings (who has the longest winning streak at 74 games) are the most successful players in "Jeopardy!" history. Watson, named for IBM founder Thomas J. Watson, is powered by 10 racks of computer servers running the Linux operating system.

"You are about to witness what may prove to be an historic competition," host Alex Trebek told viewers at the top of the answer-and-question quiz show.

No question, Watson proved to be an amazing competitor — maybe even a little creepy in the speed and accuracy it displayed.

With categories including Beatles People, Olympic Oddities and Name the Decade, the round got started with Rutter choosing the first answer, Alternate Meanings for $200: "4-letter word for a vantage point or a belief."

"What is a view?" was Rutter’s correct response.

But Watson took charge with its question to Alternate Meanings for $400: "4-letter word for the iron fitting on the hoof of a horse or a card-dealing box in a casino."

"What is a shoe?" said Watson in its resonant electronic voice.

Its next selection was the game board’s Daily Double, and, after wagering $1,000, it correctly named the literary character being sought: "Who is Hyde?"

Watson was dominating to the tune of $4,000, against $200 each for Jennings and Rutter. Then Rutter, giving hope to worried human viewers, began his rally.

Along the way, Watson made a few embarrassing stumbles.

After Jennings incorrectly said the 1920s was the decade in which Oreo cookies were introduced, Watson jumped in with its question: "What is 1920s?"

"No," Trebek told the supercomputer. "Ken said that!"

Rutter got it right when he responded, "What are the 1910s?"

Later, Watson slipped up on the answer "Stylish elegance, or students who all graduated in the same year."

"What is chic?" ventured Watson.

"What is class?" Rutter correctly said.

The exhibition tournament will continue with the Double Jeopardy and Final Jeopardy rounds of the first game airing Tuesday and a second, complete game airing Wednesday. The overall winner will collect $1 million.

The bouts were taped at the IBM research center in Yorktown Heights, N.Y., last month. Both men and Watson have managed to keep the final outcome under wraps.
