How so? The middle pair of Kings could have put together a flush that would have won the hand. The odds of putting together a flush using four board cards, or getting 9-K straight with only the K in hand, is apparently 4%. That's higher than it feels like it should be. Late to the party but there is also a chance the board is a flush or straight by itself. I watched the video, the one pair of Kings was 0% because the Aces held both of the suits the Kings had. The other pair of Kings was 2%. Hence why there was a 2% chance of a chop. The board could also come 3333A for a chop as well, or 4444A, etc. I only saw one other person who had a hand that contained an ace so there was another ace out there for a board of A2345.
