Blackjack betting systems
Flat bets and progressions are money plans. Basic strategy is a card plan. They are not the same thing.
Betting
A flat stake keeps the loss speed predictable. A progression raises the stake after a loss and can empty a bankroll at a bad shoe even when you play the right card.
Table limits end a progression early. If the next double would pass the maximum, the system has already failed.
Cards
Basic strategy is a chart of hit, stand, double, and split for a given ruleset. Rules differ: dealer hits or stands on soft 17, and the number of decks changes the chart.
This site does not provide a betting service. Use the chart that matches the table you opened on that operator.
