The Math to Blackjack - Splitting, Doubling Down and Insurance

I always knew that insurance was a manipulation, just unnecessary expenses, and I was not mistaken. As fairly simple calculations show, insurance is something that should be avoided in any case. Thank you for the informative learning series.

I guess If you are going to play this game, you might as well learn perfect strategy. Maybe I'll give it another go. Thanks

Until today I didn't dare to split anything other than aces and eights. But I've reread this tutorial series several times and I think it's time to expand the range. At least it's worth taking the first step.

It's obvious that it makes sense to split aces and cards like 8s, 9s, and 10s. Thanks for the accessible explanation.

In blackjack, mathematical decision-making is essential to maximize expected value, especially when doubling down and splitting.
Doubling down is most effective when the dealer is showing a weak hand (4, 5, 6), as this gives you a significant statistical advantage.
Splitting turns unfavourable hands into a profitable position; splitting aces and eights is mandatory.
Insurance is a mathematically flawed decision that increases the house edge by over 7%.
Splitting and doubling should be treated as aggressive offensive tools, while insurance should be treated as a trap to be avoided
