There is a thin line about hero folding and making bad folds. And when it comes to TV-poker, people are usually extremely results oriented. But having watched the first two hands in that video, the players folding seem to have solid reads, that their opponents had no bluffs at all in their range, and would also not raise any worse hand for value.
In the first hand its a pot
odds issue, where there was almost no stack left behind. It was also unlikely, someone would call flop and turn with just bottom pair. So when the bottom card become trips on the river, and they raise, they never have trips, and they never
bluff. So all, thats left, is a boat or maybe occationally another straight, but even that might not raise on the paired board, or it might have raised ealier.
In the second hand there is an open from QQ, a call from AA, a 3-bet from KK, a 4-bet from QQ and then a backraise 5-bet from AA, which makes both KK and QQ quickly fold. And I can understand why, because what hand ever takes that line other than AA? Maybe sometimes KK, but if you have KK yourself, it has to be AA. So here the problem is a complete lack of balance from the player with AA. If she had 3-bet, when the action got to her first, then she could have some bluffs, and she would likely have gotten at least one opponents stack.
