Seriously. What was Ken thinking?
Ken had 65,600 from game 1 compared to James's 34,181. In game 2 Ken had 23,000 to James's 44,000. Ken has to (rightfully) assume James will bet everything on the 2nd game which would give him a 2-game total of 122,181 if he were to answer correctly. Ken would need to accumulate another 56,581 to match that score which would mean he would need to go into final jeopardy with at least 28,290 but he only had 23k. Betting zero was the only way to maximize the chances of winning. I am just shocked that James got it wrong.
