Basic strategy is one of the few set-down blackjack strategies that casinos are pretty cool with allowing players to use. But there is a reason behind that. Casino staff will allow the myth to perpetuate that basic strategy guarantees wins. Then, after a few consecutive losses, they can watch as players toss aside their basic strategy cards and return to playing haphazardly without strategy.
I am going to say this: Basic strategy does not guarantee players a win every single time.
Read it. Understand it. Remember it.
Let me ask you something, what is the percentage of losing three hands in a row?
That answer is 14%. You have a 14% chance of losing three hands in a row, even when playing according to basic strategy. That is because basic strategy gives you the best statistical play for any given hand against any dealer up card.
But no hand and dealer up card combination is 100% in favor of the player, unless it is a natural blackjack but then there is no need to tell a player what to do then. And since no hand and dealer up card combination is 100% in the player’s favor, players have to expect to lose a few hands. It happens. Not even players who are skilled in card counting will win every single hand.
Even though you can expect to lose some hands when playing blackjack, it does not mean abandoning basic strategy. It is still your best blackjack took against the casino; playing it perfectly—meaning no deviation, players—can lower the house edge to 0.5%, giving it the best edge of all the casino games.
