The Checker Maven

Dang Tough

Tough steak? Bit off more than she can chew? The steak might possibly have been a little less tough, and more appealing, if it was tenderized and ... cooked.

Tough in checkers, of course, means something different (and so does "cooked" but that's a story for another day). It seems like we've published quite a number of tough problems lately, but hopefully they've been interesting and instructive. With that out of the way, we're going to publish one more. It's a good one, and although we've lost track of the source, it's nonetheless pleasing--- and tough.

Black to Play and Win

B:W17,18,20,22,23,24,30,31,32:B1,4,6,8,9,10,11,12,16,21.

Yes, Black can win this position with skillful play and quite a bit of patience. That's by way of saying that the solution is rather long and requires careful application of technique. Are you tough enough to stick it out and gain the win? But when you're ready, it won't be very tough at all to click on Read More to see the solution.null



Solution

As we mentioned, the solution is long and so variations are possible. Please explore further with your computer, if you wish.


1. 10-14 ...

Not the immediate 10-15, which allows a draw by 17-14.


1. ... 17x10
2. 6x15 24-19
3. 15x24 32-28
4. 1-5 28x19
5. 9-14 18x9
6. 5x14 22-18
7. 11-15 ...

Brilliant!


7. ... 19x10
8. 14-17 20x11
9. 8x22 ...

Material is even; how does Black win?


9. ... 10-6
10. 22-25 6-1
11. 25-29 1-6
12. 29-25 6-10
13. 12-16 10-15
14. 25-22 15-19
15. 16-20 19-15
16. 20-24 23-18
17. 4-8 18-14
18. 8-12 15-11
19. 24-28 14-10
20. 28-32 10-6
21. 22-18 6-2
22. 17-22 2-6
23. 32-28 6-10
24. 28-24 10-15
25. 18-14 11-7

Not much else to play. White's lack of development is taking a toll on his game.


26. 12-16 15-10
27. 14-18 30-26

White tries something different.


28. 22-25 26-22
29. 18-23 22-17
30. 24-27! 31x24
31. 16-20 24-19
32. 23x16 ...

Black will win. Tough solution? Yes, but logical and instructive.
