These are just a few simple rules to follow when you are playing either live or online. Creating a pleasant atmosphere will enhance your game and experience at the tables. 

Don’t give lessons at the table. In poker, money is made by outplaying weaker opponents. This is a battle, and you aren’t helping anyone, including yourself, by pointing out their mistakes. Yes, it is frustrating when they suck out on your good hands, but know that in the long run most of them are dead money. Let it be their responsibility to read some poker books or take some lessons if you feel their game isn't on the same level as yours. Even if your comment is meant to intimidate them, it just may be what inspires them to improve their game.   

Be a gracious winner, and a gracious loser. There is nothing worse than watching someone win a tournament and then conduct themselves in an offensive manner. Rubbing it in to someone that you are better or more skilled than they are is never good form. You want people to play against you again, especially those you beat, and there is little chance of that happening if you make them feel inferior. Same goes for losing. Your pride may be stinging, but a handshake and congratulations go a long way. 

Don’t heckle the dealers. Talk to any poker dealer and they will tell you in great detail some of the garbage that they have to put up with - dealing with drunk patrons, keeping the game moving, as well as listening to nasty comments from the players. The dealer didn’t choose your cards, and it isn’t their fault that your opponent caught runner-runner flush. The same rule applies to playing online poker. If you honestly believe that the random-number generator is working against you, then it is probably a good idea to ask yourself why you still play for real money on that site.
