Players can use the Chat feature to talk with other players and to the dealer as well. It comes without saying that everyone has to be polite and not insult anyone at the table.
Are the rules for the Live Games the same as for their online counterparts?
Live dealer games have the same basic rules and once players learn them they can adapt to any version of the game.

But the fact of the matter is that once a player learns the basics of the game, they can easily understand what is going on in front of them.
