What a poker face hides Crossword Clue

 What a poker face hides is emotions.

A poker face is an expressionless face that does not reveal one's emotions. It is often used in poker to prevent other players from knowing what cards one has. However, poker faces can also be used in other situations, such as when one is trying to hide one's true feelings or intentions.

There are a number of ways to achieve a poker face. One common technique is to relax the facial muscles and avoid making any unnecessary movements. Another technique is to focus on something else, such as one's breathing or the room around one.

It is important to note that not everyone is able to maintain a poker face all the time. Even the most skilled poker players will occasionally give away their emotions, especially if they are feeling stressed or excited.

However, with practice, it is possible to learn how to control one's facial expressions and maintain a poker face in most situations.
