A "Street" is when the dealer puts cards onto the table during a hand. You bet on each street. In Texas Holdem it is
- Dealer gives each player two face down cards. Then betting.
- Dealer puts three cards face up in the center (the "flop"). Then betting.
- Dealer puts one card face up... the "turn" or fourth street. Then betting.
- Dealer puts one last card face up... the "river" or fifth street. Then betting.
Most casinos take a "rake". This is a percentage of each pot.
At the new Boston casino there is a 10% rake up to $5 a pot taken each hand. After each round of betting the dealer will grab 10% and put it off to the side (there is a box with a little lever). At the end of the hand the dealer pulls the lever and the money falls into the box. There are roughly 30 hands dealt an hour, most of them will reach the $5 limit. I estimate that each low limit table nets about $120/hour.
Once the casino takes its rake, any money I win is coming directly from other players. I am not playing against the house.
