Capers on the Kelso: Lucky 13

20160613-lucky13.jpg

13 is viewed by some as a bit of a "shady" number but we've always liked it. For instance, how can you argue with that great-looking All-American meal above, served by the Lucky 13 Bar and Grill in Salt Lake City?

This is the 13th installment of "Capers on the Kelso" from Willie Ryan's Tricks Traps & Shots of the Checkerboard, and we think you're in luck once again. These pages in Willie's classic book contain an unbelievable wealth of great checker material. Today's position is subtle rather than explosive.

We're still working with Willie's "Variation 3" and in "Note B" of the text we find another fascinating and instructive situation.

Here's the run-up, without commentary.


1. 10-15 22-18
2. 15x22 25x18
3. 6-10 18-14
4. 10x17 21x14
5. 9x18 23x14
6. 1-6 29-25
7. 12-16 26-23
8. 16-19 24x15
9. 11x18 28-24
10. 8-11 31-26
11. 4-8 23-19
12. 6-10

The correct move here was 6-9. Willie now calls this "a dead loss." Indeed, it is; but White will require patience and technique to bring home the win.

12. ... 25-21
13. 10x17 21x14
14. 7-10 14x7
15. 3x10 24-20
16. 10-14 19-15
17. 5-9 15-10
18. 9-13 10-7
19. 8-12 27-24
20. 13-17 7-3

White gets the first king, sometimes a winning advantage.


21. 11-15 3-8
22. 2-6 8-11
23. 6-9 11-7
24. 18-22 7-10
25. 22x31

Black gets a king, but it's too late and the king is too immobile.


25. ... 10x19
26. 14-18 19-15
27. 18-23 24-19

Not 15-18 31-27.


28. 17-21 19-16
29. 12x19 15x24
30. 9-13 20-16
31. 13-17 16-12
32. 17-22 12-8
33. 22-25 8-4
34. 31-26 4-8
35. 26-22 8-11
36. 25-29 11-15

White Wins. The man on 23 falls after 29-25 24-27. There was no big secret to this win; it just took accurate, methodical, and steady play.
