Look at the other players before you look at your cards
When the action begins pre-flop you should be looking at the other players at the table to see if you can pick up a tell or body language that will give you a clue as to what your competition is holding. Don’t look at your cards till the action is on you. If you do sometimes when you have a good hand you will give away your strength my looking at your chips stack or making a premature motion in anticipation of betting or raising. Don’t worry about taking the time you need. People will wait for you. Pay attention to others as they are paying attention to what you are doing.
