Lucky numbers

There are different counting systems that give the player of blackjack an advantage, provided that the game is honest and the cards are shuffled well. But there are also methods which can be used to trick the player.
One of the most effective and simplest ways for a dealer to cheat is to look at the top card and after that deal that card or the one below. This is called the second. A good second deal can be done so smoothly and quickly that the eye of the player will generally not detect it. Usually the background noise of casinos covers the different sound from dealing the second card instead of the first one.
