I have read several interviews with Mr. Chu. He as found a strategy that helps him win on the TV show. In one interview he said it was based on Game Theory which he studied until he understood the various approaches. He then looked at the rules of Jeopardy and devised a strategy that maximized his chances for a large payoff.
He studied. He thought. He devised a plan. He carried out his plan. He is winning (a lot).
This seems like a life example of how to get ahead. I have not seen him on TV, he may have the personality of a rock, but that doesn't matter. He has shown that hard work, study, planning and execution payoff. we all could learn from his example.
I don't see anything wrong with his actions. How about the Gulch residents? Do you see anything wrong?
