People who play Blackjack could make more money if they avoided these 4 common mistakes:
1. Money management: They do not manage their money properly. Add to your bet when you're winning. Go back to your original bet when you lose, and stay with that bet until you win again. If you lose 5 or 6 hands at the table you are playing, go to another table.
2. They do not Double down when the opportunity presents itself in most cases you always double down on a 10 or 11. Your chances of winning are increased and you make more money.
3. They stay when their card count is under 17 and the dealer's up card is 17 or higher. They think that they are safe if they don't hit and hope that the dealer does not " bust ". 75% of the time they are wrong. If they have a 12 - 16 in their and the dealer has a 17 - 20, they must hit in order to increase their chances of winning. Time after time another player who hits his hand gets the card that would have made the other person's hand a winner OR at least a push.
4. They do not learn basic strategy. Many casinos - and their gift shops - offer basic strategy cards or pamphlets to players so that they can play the right way. If a player does not have a basic strategy card or pamphlet, they should ask the pit boss if they have one. If the casino you are visiting does not have any, ask every casino you visit for one. You will find a casino that offers the basic strategy card. This can make the difference between being a winner or a loser.
There are many more mistakes that players make, but this is just a small sample. How do I know this? Because I am a Pit Boss in a casino and have worked in the casino business for over 25 years.
