There are a lot of things to keep in mind when you start playing poker, but often it's the little things that can cost you your life at the poker table. Being mindful of table etiquette and what you're supposed to do can cause you to lose focus on what's in front of you - the cards.One of the best things you can do at the table is to know exactly who you are playing against. Are they tight, loose, passive or aggressive? You won't know unless you keep an eye on them. And you can save yourself a few chips if you keep an eye on them when you're not in hand. See how they behave with other players, and when they go head-to-head with you, you'll have the edge you need over them.It is very difficult to win such a place.
