If you desperately need to have some sort of structure in your play, then try this simple method. It’s not really a system, just a style of play that should satisfy your need for “pushing” your bets every so often without breaking your bankroll in one giant swipe.
Once again, we’ll use $10 as our base bet. Play your straight $10 bets, then, whenever you get the “feeling”, double it. By “feeling”, I mean whatever makes you want to push a little, whether it’s because you’ve lost a few in a row or just a gut feeling. If you win your doubled bet, then keep playing that amount until you lose, then go back to your original amount until you feel the need to push the action again.
The reason I back this style is because it allows you the thrill of the bigger bets, without any devastating losses. All that’s left now is to make sure to know when to take the casino’s money and run! — And make sure, when at the blackjack table, to be aware of the rules of etiquette.
