Kim played a good game. I think turning down 82 thousand was not greedy because of the safety net, but I would have taken 37 thousand because 200 thousand was the only six figure amount left on the board.
You can call it a safety net at the offer of 82,000 because both 200,000 and 750,000 are larger than the offer with only one case to open. But it is still scary because the difference is over half a million - if the 750,000 goes off the board, the next offer won't be anywhere close to 82,000. The main reason why I am in favour of Kim turning down 82,000 because there is a 5-out-of-6 chance of not hitting 750,000.
