Rep. Rush Holt's secret to beating IBM's Watson (VIDEO)

It wasn't just man versus machine Monday night here in Washington but congressman versus machine as Rep. Rush Holt (D-N.J.) took on IBM's Watson along with fellow members of Congress during a mock exhibition Jeopardy match in Washington.

Holt told's Lauren Seifert the day after his victory "I think Watson was having a low-voltage night."

Holt might have had an advantage as a rocket scientist and, more importantly, as a former 5-time Jeopardy champion 35 years ago. "If I had known how seriously people take Jeopardy, I would have been really nervous," he said in response to how he managed to pull that off back then.

So, what was the secret to Holt's success? "Part of the strategy is to press the button before you know the answer, if you think you know the answer."

Doesn't take a rocket scientist to figure that out.
