Never forget the game objective.
Never make the mistake to think that you need to approach as close to 21 as possible.
You need to have hands higher than the dealer. That’s the key.
You win if your hand totals 21 or less when the dealer busts (hand exceeds 21).
You win if:
Your hand totals 20 and the dealer’s hand is 18 you win, if you bet $2, you get $2
You have anything under 21 and the dealer busts
You lose if:
You have 19 and the dealer has 20.
