IBM's Watson, which ended up tied with Brad Rutter at $5,000 at the halfway point of game one (Monday), and leading Ken Jennings ($2,000), won easily with a total of $35,734 vs. Rutter's $5,400 and Jennings' $2,400. The two humans managed a total of only 5 correct answers during the second day of the match.
At one point, Watson landed on a Daily Double, and said "I'll wager $6,435," Watson said in its electronic voice. To that, Alex Trebek said "I won't ask," meaning the question that all were wondering: how did Watson come up with that bet?
It didn't matter. The answer, in the "Cambridge" category, was "Sir Christopher Wren" and the software vaulted to a huge lead with $21,035.
Final Jeopardy came, and both Jennings and Rutter bet big, and won with the correct answer. Watson was wrong, but it didn't matter, as the program only bet $947.
The Final Jeopardy answer was "Its largest airport is named for a World War II hero; its second largest, for a World War II battle." The answer was "What is Chicago?" as the reference was to Chicago airports. "What is Toronto?" was Watson's educated guess.
The second game of the Jeopardy Man vs. Machine tournament is on Wednesday, and the winner will be the player with the highest combined total between the two games. The winner receives $1 million, second place receives $300,000, and third $200,000. IBM said all of Watson's winnings will go to charity; Jennings and Rutter plan to give away half of their amounts.
Ken Jennings set the Jeopardy record for most consecutive wins, with 74. Brad Rutter has won the most of any Jeopardy champion, $3.25 million. So far, it does not seem that Watson is impressed, or intimidated.
