It's also important to realize that casino rules are vastly different from those that you employ in a friendly family game. If these rules are ignored or violated it may cost you a very valuable pot.
The chief advantage to playing in a casino is that the house provides a dealer. You don't have to worry about Uncle Joe dealing from the bottom of the deck or some card shark dealing "second", saving the best card on top for himself and dealing the cards underneath to the other players.

It will cost you a little to play in a casino. Because there is no casino advantage in poker, the house charges players for providing the space and the personnel to offer an honest game.
In most casinos, the house will take a "rake" from each pot. A rake is a percentage of the pot that is checked by the dealer after every round of betting.
This will vary between five and ten per cent, and most casinos put a limit on how much money will be withdrawn from each pot.
In some casinos, though, the house charges a "seat rental". This is usually an hourly fee that progresses upwards with the limits. Unlike poker played at home, casino poker doesn't necessarily require an "ante" or bet prior to receiving the initial cards.

In Texas hold'em, a "blind" is used. A blind is when one or sometimes two players put up a small ante before a round begins. The blind is rotated in clockwise direction around the table.
When betting commences, you must bet in a prescribed sequence depending upon the rules of the specific game. The person with the high hand will make a bet in sevenncard stud. The player to his left then must "call" (match that bet), "raise" (increase the bet), or "fold" (throw his cards in and withdraw from the hand).
A player who acts out of turn can influence the play of the others, so it is important to take your cue from the dealer as to the correct time to make your bet.
In Texas hold' em, the first "live" player to the left of the "dealer" makes the initial wager. A live player is one who has not folded on a previous round.
And while the casino uses a dealer at Texas hold' em, each round a player is designated as the "dealer" so that the deal will start with a different player to the immediate left of that designed dealer. The "dealer" is indicated by a "button" in hold'em.
