Grandmaestro: Here are some games I played - using some gambit opening lines:

Using the "Fife" man-down opening - A well known, strong gambit in English Checkers style.

1. 24-19 10-14 2. 22-18 11-16 3. 28-24 16-20 4. 19-15
{Fife Opening - Inviting the gambit.} 14-17 5. 21x14 7-10 6. 14x7 3x28
{Gambit accepted! This is a well known opening line used in English Checkers.} 7.
25-22 8-11 8. 29-25 9-13 {Black probably had better with 4-8.} 9. 18-14 2-7 10. 25-21
6-10 11. 23-18 10x17 12. 21x14 4-8 13. 26-23 12-16 14. 31-26 8-12 15. 23-19 16x23 16.
26x19 11-16 17. 27-23 20-24 18. 19-15 13-17 19. 22x13 24-27 20. 15-10 7-11 21. 10-7 27-31
22. 7-3 31-20 23. 14-9 5x14 24. 3x21 20-24 25. 21-3
{Now seems like a drawn game with a lot of potential for an interesting ending with the flying kings.}

And another game, with another known gambit used for English Checkers...

{White maybe escapes for a draw - but it's worth a try for Black.} *

Now, a not-so popular line played in Checkers - but another very drawable and strong gambit....
