Your face is the first giveaway that could cost you a game of poker. Keeping your emotions and reactions in check regarding hands dealt to you is a key part of poker. Any type of expression sacrifices your power in situations with your opponents. Clear your mind, wiggle your face to loosen the muscles, take a deep breath, and relax. You want to be in control of the situation and if you're too stressed, you can lose that control. Hiding your reactions is power because no one knows what you're thinking or what you're about to do. You can win the upper hand by showing people you are confident and intimidating by locking eyes with them. Meeting people's eyes also shows that you have nothing to hide so they don't know what to expect from you. Look at the bridge of their nose to stare them down and keep your focus. Staring into space or focusing too hard on your cards is also how your poker face can be compromised. It either shows that you aren't paying attention, or that you're concerned for your hand and chances. Remind yourself to blink so that your eyes don't dry out while you concentrate. Excessive blinking can also show nervousness, so don't go overboard. There's a balance between blinking enough to keep from staring and keeping your eyes focused so they don't flit around. Staring too hard can also cause your shoulders to bunch up and posture to suffer. Focusing too hard on one thing visually can also distract you and you may miss an important play. Your mouth is the main support for your face muscles and any tension, smile, frown, or smirk will influence the rest of your face. Relax your jaw first by letting it go slack, creating space between your back teeth. Open and close your mouth a few times to help relax as well. Avoid showing your teeth. Whether it's for a small grin or grimace, visible teeth means your mouth is moving and movement can give you away. Don't grind your teeth. Your jaw will show the pressure your teeth are under. Don't look up or to the left or right out of the corners of your eyes. These are all tells which are little clues to your opponents that you have something to hide, whether it's a good hand of cards or bad. It's hard to do, but minimize your eye movements. Even squinting or excessive eyebrow raises can give away your reaction. To protect yourself, wear sunglasses so you don't have to worry about giving anything away with your eyes. Sunglasses won't be a problem indoors if you have enough lighting.
