Hello,
there are three groups of Black Jack players. The ones who play just for fun and playing style is done according to gut feeling. Players from 2nd group are yelling at the last box every 3rd hand, because one is always wiser after the event.
Players philosophy from 3rd group is discipline, and they are playing basic strategy.
Now you have to decide, what kind of target group you want. After the decision you must write content for exactly that specific group.
Content suggestion:
Group 1: Easy to learn money management tactics and something about the waves of fortune.
Group 2: Progressions, winner stories and something about shuffle machines and RNG.
Group 3: Basic Strategy, also advanced Basic Strategy and stop-loss tactics.
