Well, this has been one of the old topics of debate for poker players. On a poker table emotions play an important role to recognize how a player is playing and how one can conquer him or her. Players that are not able to control their emotions use multiple techniques to cover the same like involving others in discussions of different topics or by bringing some other person to the center of the debate. Those who aren’t good with words end up covering their faces with sunglasses. Though for few sunglasses are just a way of presenting themselves as cool and calm yet for others it is one way out to cover their emotions and nervousness. I would suggest one to learn controlling his / her emotions instead of covering them. No one sitting with you on a poker table will appreciate you wearing sunglasses when others on the table aren’t.
