Arthur Chu uses strategies that outrage some home viewers:
"He has two ways of boosting his odds of success: searching for the Daily Doubles and eliminating them from the board, even if he knows he’s not going to guess it right, just to make sure his opponents can’t get ahead of him; and being careful when he bets on the Final Jeopardy, so for example, he takes the chance that he will tie with the second place winner.
...Chu joined CNN’s Jake Tapper on Tuesday to reveal his secret, unorthodox, unconventional methods: “The very first thing I did when I got the call to be on Jeopardy! was I sat down in front of my computer and Googled ‘Jeopardy strategy.’”"
