What are a short list of easy to follow rules that will help me win at blackjack?

I find alot of contradictory information, if this, then this, and many people disagree. I’m not looking for doing math calculations in my head, just few basic rules that will help me avoid losing as much.

I did find this:

and this:

How to Bet in Blackjack

anyone agree? disagree?

Feel free to offer your own system as your answer so that I can win at blackjack more!

Here are some specific questions:

Do you always split 10′s and 9′s? Doesn’t it matter what the dealer is showing?

Do online casinos cheat?
