I guess my problem with gamers on Jeopardy is that it goes against the grain of the show's premise: buzzer ability being equal, the person who knows the most will win, period.
If someone is smart enough to win, they don't need a bag of tricks. Gamers who don't know the answers will still lose control of the board, and won't score paydays from Daily Doubles, and they won't win the game. So the only gamers who come out of it as success stories are the ones who were already smart enough to win without the gymnastics and mustache-twirling. So, why bother making yourself look like a weasel on such a highbrow TV show?
