The Checker Maven

Highly Practical Practice

Editor's Note: Ed Gilbert pointed out a flaw in the original setting. Here's a corrected version.

There's theory and there's practice. The electrician shown working above is applying practical knowledge no doubt mostly obtained through study and experience. A similar concept applies to our game of checkers. We need to learn the theory but in the end, practical application is what wins or saves games for us, and the more experience we have, the better.

In the diagram below, credited to regular contributors Lloyd and "Gosh Josh" Gordon, White is a piece up but Black can achieve a draw--- with careful play.

Now, being something in the nature of a speed problem, the draw is neither difficult nor sophisticated.

Experienced players will have little trouble; improving players may take a bit longer, but either way, it's a nice little workout. Give it a practical try and then take the practical step of clicking on Read More to see the solution.20050904-symbol.gif



Solution

The original "solution" was as follows, and it was flawed:

24-27 23-26 27-31 26-22---D 1-6 22x29---A 31-26 20-24---B 6-10---C 24-27 10-15 27-31 15x22 to a White Win.

A---Black evens the piece count but at the cost of trapping his king.

B---Not 29-25 26-22.

C---Now with the Black king stuck on 29, White goes after the unsupported Black man on 18.

D---Looks great, evening the piece count, but loses! Instead 26-23 draws as White can make no progress. Try it with your computer; the landscape is full of potential Black two for one shots. But 26-22 is how Black, with all good intent taking a move that many would make over the board, can go wrong.

Instead here's a straightforward drawing line for Black if White plays a different first move:

24-28 32-27 1-6 27-31 28-32 31-26 32-28 26-22 to a draw.

Again, thanks to Ed Gilbert for pointing out the flaw in the setting.
