This situation showed how a professional player sinks to the bottom. I liked how it was shown in the film, I think in reality there were many such situations. I would call this a guide for professional players. If they feel that they are sinking to the bottom, they should remember this part of the film, it will probably stop them.
And finally, it really happened when he experienced loss after loss, which caused him to lose everything and even have to borrow money. It will also not give him a chance to win the game because when a person is in high emotions, he will not be able to think clearly, and his gambling game will become random.
Yes, to put it simply, he succumbed to emotions. I know that this infuriates professionals the most when those from whom they are accustomed to earn money show them the opposite. This undermines their self-esteem about themselves, about their game. They think it also had a big impact that the whole table was watching and laughing. Probably some deep feelings and emotions from childhood that did not manifest themselves in poker were at work, which allowed him to win until that moment. The rest of the professionals also need to think about this, suddenly the moment will come when they will have something similar.
