Traditional seven card stud is a very popular game, and considered by many to be a more "skillful" game then holdem due to the extra information a skilled player can gain from the exposed cards. The game is played with 2-8 players. Most commonly played with fix limits the game can also be found played with a pot limit. The pot limit game gives a further advantage to a skilled player in that they are now more able to manipulate pot size and the pot odds an opponent  is offered. 
 

All players ante to start the hand. Each players is dealt two cards face down (hole cards) and one face up (exposed) card. This is called third street. The person with the lowest card exposed card must put money into the pot (effectively becoming the blind for you holdem players).  The low card can 'bring in' which is to bet half the small bet or this player has the option to "complete" making it a full bet. The other Players can then, raise, call, or fold in turn.

Ex: Third Street	Forced Bring In
You	Opponent 1	Opponent 2

4th street: An exposed card is dealt to each player, followed by a round of betting. For fourth street onward, the person with the best exposed hand begins the betting (i.e. if someone has AQ exposed, another has 55 exposed, and someone else has 48 exposed, the person with 55 goes first because he has a pair of 5's.)
 

Ex: Forth Street		First To Act
You	Opponent 1	Opponent 2

5th street: An exposed card is dealt to each player, followed a round of betting. If the game is played in a fixed limit format, this is where the big bet would kick in. A big bet is usually equal to twice the small bet but this does vary.

Ex: Fifth Street	First To Act
You	Opponent 1	Opponent 2
