The BEST guide to online casinos

Blackjack players have had success in beating the house by using card-counting systems. These are based on the principle that the make-up of a deck of cards is changing as the cards are played. A deck is in the player's favor when it has more ten-count cards in it, because the player has a greater chance of getting blackjack, which pays 3:2 (more money than with other winning hands).
By assigning a value (such as +1 for high cards and -1 for low cards), a player can roughly determine the ratio of high cards to low cards remaining in the deck at anytime. When the deck contains more high cards and the odds are in his favour, he increases the amount he bets. When the deck contains more low cards, he bets the minimum. The count also guides his decisions on whether to hit, stand, double, or split.
Note: Most online casinos shuffle the cards after each round. This prevents players from using their computer to keep a count to get an edge. When gambling with online casinos, you are better off sticking with the basic blackjack strategy.
