As well as the popular strategies that have been purported as having some success in the game of blackjack and online blackjack, the only strategy that has shown to be consistently effective is the strategy chart. Players who have managed to successfully card count have also claimed to have had positive results when playing blackjack. In addition to the strategies that are specific to the game of blackjack, the progressive betting system has also been claimed by some players as being an effective blackjack strategy. The progressive betting system is not specific to the game of blackjack and is commonly used by players at the casino. The way the positive progressive system works is that after a win at the casino the player will go on to increase his bet. The negative progressive system encourages players to increase your bet after a loss. Although these systems are controversial when playing blackjack for real money it is important to put a cash limit on your game so that it does not get out of hand.
