no such thing. Study the tables and play the games you can beat. when u start losing, leave. Discipline and money management. Everyone knows how to play, and this will give you the edge and pump up your EV. Treat it as a marathon and you will be a winner. Take the casino's formula. a 2-5 percent advantage over a long period makes empires. Why? They never deviate. Players may win, but only temporarily because the house always wins in the long run. Take you beats in stride and that will maintain your EV. Luck is temp. accept as the cost of doing business and keeping your slaves alive by shearing, not skinning them. Treat it as a business and take the gamble out of your play. This will minmize losses against serious players and capitalize against the weak ones. Good skill to you, not Good luck
