A poker face is very hard to keep up for hours and hours of playing. There are quite a few people on the table who observe any expression of your face and even look at your throat how heavily you are breathing. When playing serious for money I would recommend to wear sunglasses, a hoodie and. a scarf. This makes sure that other people can't read you that easily. Being unpredictable also helps, as long as you are playing good poker.
Maybe we can use poker face in a limited time, so we do not have to feel tormented using that.
But for a pro poker player will figure out the other way to give a trick to their opponent, so the opponent will not know if they have a good card.
Using those things can help us be undetected by the opponent, but we should be aware of the rules because sometimes, the casino can use that rule.
But it is hard to be unpredictable in a poker game as we can meet the pro poker player, which is not easy to trick them.
