When Arthur Chu got the call saying he'd been selected to go on Jeopardy, his first move was thorough and decisive: He went to Google and typed in "jeopardy strategy."
"I knew that just like in terms of my natural knowledge base, I wasn't ready to go on Jeopardy," Chu told me on the phone this morning. "I wasn't like Ken Jennings—automatically knowing everything from the top of my head. So I had to train."
By training—that is, going through Internet message boards and reading up on past Jeopardy winners—Chu developed an unorthodox strategy that has made headlines over the last week. It's rare, controversial, and effective—and it's turned him into something of a grand villain for some fans of the long-running quiz show. Just one glance at his Twitter feed will show you some of the ridiculous vitriolic messages he's gotten over the past few days, as his story—and winning streak—started picking up steam. (He's won four games so far, and needs one more to get into the Tournament of Champions. His next appearance will be televised on February 24.)
