The betting limits aren’t going to change your playing strategies.
The number of decks of cards has an effect on the house edge against a basic strategy player.
If the game is dealt with a single- or double-deck of cards, the dealer will usually hand shuffle the cards and there is no issue here.
You are better off playing at a full table rather than a table with fewer players, or worse, heads up against the dealer.
Some playing rules will decrease the house edge whereas others increase it. It’s important you know the good rules from the bad ones.
Each of the good (player favorable) and bad (player unfavorable) rule affects the basic strategy, some greater than others.
