Here are some very obvious acts of etiquette that each player should know and practice when playing in a tournament.
In casino gambling, someone might get a bad card and throw the cards at the dealer, or start jumping up and down cursing, or just act disrespectful in general. In tournament play, have respect for the people around you. Watch your language and don’t come to the table intoxicated. (Some casinos will let you smoke and drink at the table, but most will not.) Some tournaments may allow you to talk with fellow players; others prefer no communication between the players at all. Don’t try to change the rules; the rules are there for tournament action. You will be playing anywhere from forty-five minutes to an hour, so show respect for the rules of the tournament and especially for the dealer, otherwise you may be ejected from the tournament and the casino.
The official language of all blackjack tournaments (at least in the United States) is English. ANY communication between players and spectators, whether by signaling or speaking in a foreign language, can be considered cheating and therefore, cause for ejection.
You are not allowed to cover up your chips. Other players must be able to see your chips at all times. Mixing chips and colors is not permitted and this is one of the most important things to remember. You may not create different piles with all different colors. This is known as a "dirty pile," meaning you cannot slip a purple chip in between a pile of green chips. However, if you have a large number of chips, you are allowed to make different piles of the same colored chips.
In a tournament where talking among players is allowed, an important element to watch for is comments or questions you may get from another player. For instance, say someone bets $450 and the guy next to you says, "I’m not sure what that person just bet? What do you think?" DO NOT HELP HIM. If a guy looks at me and says, "I’ve got $3,400 chips, how many do you have?" Just respond with something like, "I’m new at this. I don’t know how to count." If anyone is stupid enough to tell you how much he has, just turn to him and politely say, "Thank you." You don’t want to volunteer information especially to your opponents.
If you’re down to hardly any chips and you’ve got no shot at winning, do not help the guy next to you even if he is a friend of yours. No helping other players at the table, at all.
In Tournament Blackjack, the dealer is not supposed to speak to the players. If a dealer does say something, you are within your rights to let one of the tournament directors know that the dealer is communicating with the players. The director will see to it that it doesn’t happen again. Tournament Blackjack dealers are not like the friendly ones you may run into at the casino tables. They are usually expressionless, mute and all business.
