How many decks?

[mscott]

How many decks do they commonly use in hold'em?

At real cash tourneys?
On online sites like Full Tilt or Party Poker?
When you are playing a home game?

Just wanted to know how big of a difference there was and if there was a difference at all. Or if there is a standard that everyone should be playing with?
Thanks

They use only one deck of cards. If you have noticed a couple of other decks in front of the dealer it is because he wants to save time shuffling the decks. But he uses only one deck of cards.

I have only seen it played with one deck. I am sure it is played with more at times, but I just have not seen it.
