It is said that many people play Texas Hold 'em well. How is this reflected? The probability of counting cards? ask for advice

In my opinion, people who play Texas Hold 'em well include those who are good at math, intuitive and good at reading people's body language (offline only).

Playing Texas Hold 'em requires a certain amount of mathematical calculation ability, and you don't need to be top-notch.

If friends play, they just need to calculate the probability. For example, I am listening to cards, so how many ways do I have? What are the chances of turning over the cards I need? For example, the card face is 456K, and I have 8 in my hand, and there is no flush. I want seven most. If it's 8, I can make do with it. Then my probability is four sevens and three eights divided by the number of cards in the library. These are simple addition, subtraction, multiplication and division, which are easy to calculate.

If you play more formally, such as the high-priced Texas Hold 'em on the show, you need to look forward to it. For example, if I meet my opponent with a big bet on the flop, then I have to think about it. If I call, what are the odds now? What are the implied odds (that is, if I turn the card I want, will my opponent pay me, which depends on my opponent's card type and chip number)? If I raise, what is the opponent's fold rate? Or if I have a card, what are the chances that my opponent is also a card, and what are the chances that I will listen to cards or just bluff? Combine all the factors and work out your income expectation. If your expectations for this action are positive, then you can do it. Otherwise don't do it.

Of course, the human brain is not a computer, and the complicated expectation formula cannot be accurately calculated by ordinary people, but even if it can be roughly calculated, it is one of the few masters in Texas Hold 'em.
