Here's a problem attributed to O. H. Richmond, and published a little over 50 years back by Tom Wiswell. He called it "Black Beauty":
Now, you'll surely find that this is a neat problem and a "real twister" as Wiswell would say. So solve it, check your solution with the animation here, and then click on Read More to find out what the computer has to say about this problem. It won't be what you think--- or will it?[Read More]
The Checker Maven presents as its most unusual offering for January the following mind-boggler attributed to a Mr. W. Veal. It is a "stroke" problem, that brand of spectacular, if unrealistic fireworks that appeals to some and is anathema to others.
To be sure, the position below is composed and obviously impossible; there just aren't that many pieces in a game, and they could never get into such a contorted distribution. But for the fan of the stroke problem, realism isn't the issue. The whole point is a clever key move or two, and lots of action afterwards.
Now, depending on what computer program you use, you may or may not be able to coax it into solving this for you. But you really should try it on your own. And since the play is mostly all forced, the challenge is more in trying to visualize the moves than it is in actually finding the solution. But the visualization challenge is mind-boggling indeed. Can you make it out or will this just drive you over the edge?
The title of this problem is a saying of Tom Wiswell's, and when you find (or see) the solution, you'll understand the wisdom of it. The position arose in a handicap game that Mr. Wiswell played something like 50 years ago.
You might find this one a little difficult unless you're used to solving a certain type of problem (but if I told you what type I might be giving away too much). Good luck! When you've solved it, click here for an animated solution.
"This problem has been dubbed by experts the champion 'coffee and cake' problem. This means that you can set this problem up for your friends and bet them coffee and cake that they cannot win it."
I bet Brian Hinkle coffee and cake, and not surprisingly, I now owe him! But can you win it? Give it a good try and then treat yourself to coffee and cake no matter the outcome.

In many parts of the Northern Hemisphere, January is a cold month, and so a warmup might be just the thing! Here is a simple problem to get you started with this month's Checker Maven challenges--- but beware, they all won't be this easy!
Brian Hinkle sent us this run-up from the Double Corner opening:
A---A defense from Teschelheit's Master Play of the Checkerboard, unfortunately unsound.
B---Loses at once, although White is probably already lost. One alternative line of play from the KingsRow computer engine is this: 26-23 19x26 30x23 11-15 18x11 8x15 32-27 5-9 31-26 4-8 25-22 8-11 23-18 15-19 27-23 11-16 17-13 7-11 29-25 1-5 22-17 3-8 17-14 8-12 25-22 11-15 18x11 9x27 Black Wins.
After 31-27, the following position arises:

Only 2 players in the world have solved this 6x5 puzzle! Can you become the 3rd person to solve it?
So far only Alex Moiseyev and Jim Morrison could solve it.
On a scale of 1 to 10 (with 10 being the most difficult) Alex gave it a 7, and Jim gave it an 8.5. Both enjoyed it thoroughly.
Gerry Lopez, Leo Levitt, Carl Reno and many others have all failed to solve it - even with computer help! A number of players simply thought it was set up wrong!
The solution will be published online here in The Checker Maven on May 7, 2005.
Please send any human (no computers answers please!) solution to:

That brings up the question that is often heard about checkers being "dead." The best computer programs today are at an extraordinarily advanced level, very likely beyond the best human players. Computer programs were always relatively good in checker tactics; but now, with enormous opening databases of half a million to a million positions, endgame databases which comprehensively solve endgames of up to 10 pieces, computer programs seem to know just about everything about checkers. The University of Calgary has as its goal the complete "solution" of checkers, and they think they will do this in the next few years. We believe that they will, in fact, accomplish this feat.
But does the fact that a "solution" for checkers exists (or will exist) mean that the game is "dead"? We think that is only true if you are playing against the world-class computer programs that know the "solution." In a game between humans, especially an over the board game, checkers is not and will never be "solved." There is too much challenge and enjoyment in the game as played by mere mortals.
What has this got to do with checker problems? It's simply that these problems, especially the better and more clever or entertaining ones, show the depth of the game. Struggle with a couple of these gems and you'll see what we mean. You'll find that there's a lot left for you personally in the grand old game.
