Master basic strategy before you ever place a bet.
Once you have mastered basic strategy, the casino's edge is reduced to only .5% (half of one percent). From there, counting cards allows you to swing the odds of winning in your favor. This strategy allows you to gain a long-term winning edge over the casino, the same way casinos gain the long-term edge over novice blackjack players.
