1. keep the last row of pieces there as long as you can-this way they can't get "kinged".
2. get your pieces to the edge of the board so they can't jump you, but you can jump them
3. make sure your pieces are right behind each other, so they can't get jumped
4. Use your first king more to advance your other pieces (to get more kings) initially than to capture (unless capturing will also IMMEDIATELY allow a piece to advance). Once you have 2-3 kings THEN attack the other pieces.
5. Don't play against a computer.
There was even a guy on youtube who said a great strategy to use is that after you and your opponent has lost 3 checkers, to try and keep an odd number of checkers in each row.
It is a sad these days as we continue to see the decline of competitive checkers, but it is still good to have some laughs.
As far a advice goes for winning checkers, Lubabalo said it best to me at nationals: "play the best moves."
