You can be a great blackjack card counter, but if you get barred, all that knowledge is wasted. To help prevent getting thrown out consider the following. Don't play for more then one hour in any one casino. Don't jump your bets after a win; let it ride and double the next bet. Then double again if the count continues to go up. Try not to be the biggest bettor at the table. Sit in a seat that gives you a direct view of the table without moving your head. Never leave the square in front of you empty. Smile! Don't look so serious that you attract the attention of management. Try to fit in with the crowd as just another tourist. The main idea is never to attract attention to yourself. Work on your game and work on staying in the game.
