LOve his read on the hand. I do agree she is better than that and should not have tried there. With 25Mil left she still could have won the whole thing.
having seen this, i think the hands and table image Kristen had built to that point explained her reasons for her actions, i definitely agree she is way too good, i have always maintained the best players can pass on certain situations, i would have certainly called however.
Bluff will not always pass, she tried and got denied, its poker, but i dont think is a winning move at most of the times, but it is not a stupid move, just a hopeful one.
