Never hit a hard pat hand against any dealer upcard. The chances of improving your total is so slight, and the chance of busting is so great.

Your 17 is a very weak hand. It is so weak, in fact, that if all you got were hard 17’s, in the long run you would lose against ANY dealer upcard. Yes, even against a dealer’s 5 or 6. The only way you can win is if the dealer busts. Occasionally, you will push with the dealer, and should feel grateful when that happens.

Your 18 is a long run winning hand against dealer upcards 2 through 8, but is a long run loser against the dealer’s upcard of 9, 10, and Ace, which is not suprising.

Your 19 is a fairly strong hand. It has been said that if the player could have 19’s on every hand, she would be a long run winner against any upcard, even against 10 and Ace.

Your 20 is a strong total, and you should win about 70% of the time with a 20. But don’t spend your money just yet. The dealer will tie you with 20 almost 18% of the time, and beat you with a blackjack or 21 about 12% of the time.

Your 21 is the best you can get. You should win 88% of the time with a hard 21. But it is not a guaranteed win, regrettably. That is because you will push the dealer’s 21 about 7% of the time, and can even lose against the dealer’s blackjack almost 5% of the time.

Common Loser Mistakes:

  • Celebrating getting a 20 or a 21. Until the round is over, there should be no celebration.

Did You Know..?

The lowest total that will mathematically beat the house in the long run? 18 and a half. Too bad this cannot happen. I guess we’d settle for 19’s all day long then.
