In fact, I don't know much about all these terms🙈, but I perceive all the examples given as "bad beat". 🤷♀️
After all, in fact, "bad beat" is when we are far ahead, but in the end, we lose to a weaker hand on the river.
Having collected a straight on the flop, we are far away and if the opponent has collected a stronger combination on the river, it is a bad beat.
Set vs set, in my opinion, is not a bad beat, since, in fact, both players had pocket pairs and initially, the player with the stronger pair won. although, if the set was first assembled by a player with a weaker pair, then, for him, it is, of course, bad beat. If the player who had a stronger pair was the first to collect the set, then for his opponent it is more of a "cooler" than a "bad beat", since, having collected the set on the river, he has already lost anyway: that is, the outcome did not depend on his actions.
Aces are far ahead of any starting hand, so if the opponent gets two pairs on either flop, turn or river, it can be called a bad beat.
In the video, we see a flip on the flop, since the starting
hands of the players were approximately equal, but in the end, the player with a pair of kings caught a bad beat, since he was far ahead, but the river did its job. If the ten had not come to the river, it would not have been a bad beat for a player with a pocket pair, although many would say that it was a "bad beat" for him.
Throw stones at me if I'm wrong, but that's my humble opinion.🙈
