Good question. So, let's figure out first with chess, why they are so in high esteem. Firstly, it is their visibility, I mean that this is a game with complete information, when all players see the moves and actions of the opponent. In principle, chess, unlike poker, is a game where it is simply impossible to deceive an opponent. Secondly, psychology is very important -there is probably no more annoying and disgusting feeling than losing at chess. In this regard, chess attracts a person much more, because a person connects himself with his intellect, which cannot be said about poker, because no matter how professional you are, your skills only increase the probability of winning but will not affect the output of the desired card in any way. Poker is just a game, and the funny thing is that in this game you can make money literally out of thin air, do you think someone will like this arrangement? Some miner earns money by hard work, and you play cards and earn the same and even more.In addition, the state has almost nothing to do with your activities, which means it has no need to support you.Of course, you will say that everyone pays taxes, but it's one thing when you give money, and another when money and your workforce.
Poker is a game of deception, your task is to present your cards in the best or worst light in order to win money.And deception has always been perceived by people as a very poor quality. Probably because none of the people can accurately determine whether you are lying or not. The most important thing is that poker teaches you to cheat, and this is probably the most terrible thing, because in modern society, liars and liars do not cause much attention.
Psychologically, playing poker requires very strong endurance and self-control, your brain must walk on a string so that you play without fear of losing everything. In fact, you need to have a heart of steel to be like Stu Unger. In addition, you need to be able to manipulate people, you need to make them think a certain thing to win.
