The last offering for February is two problems in one. It's based on something published by Willie Ryan many years ago. The adaptation of the setting is rather liberal.
Here's the situation. You're in the final round of the Mega-Bowl of Checkers. The coveted title of Supreme Exalted Checker Champion hangs in the balance. Thousands of avid fans are watching from their $500 stadium seats and hundreds of thousands more are tuned in on the Checker Television Network. Sponsors have paid a million dollars each just for their 30-second commercial spots. This is really the Big Time, and you know if you win you'll become an instant media star, with wealth and fame yours without limit.
You're playing Black and it's your move:
What move do you choose? Can you show how that move wins and why the other move loses?
This excellent book of tactics is extremely difficult to find at any price. Yet, it is such a valuable reference and training book for beginner and intermediate alike, that The Checker Maven has decided to produce, over a period of months, a freely available electronic version. (Recall that we did the same with Arthur Reisman's fine book of basics, Checkers the Easy Way, available in Postscript and PDF formats.) The copyright is long expired, and there are no legal or ethical barriers to republication.
We'll present a few pages in The Maven every few weeks, as mood and opportunity catches us; and we'll simultaneously gather it all together in what will eventually become a newly-typeset printable book.
Let's start off, then, with a pair of problems from the introductory pages of the book. We've called them Two Easy Pieces, and though these are speed-solvers for the experienced player, they present important basic concepts for the learner to master. Willie's own entertaining commentary accompanies each problem.

In January we presented a mind-boggler of a stroke problem (click here to see it again). This month, we offer another brain-twister of a different nature. Take a look at the situation diagrammed below, titled Remarkable Block Problem and attributed to an author calling himself "X.Y.Z."
It all reminds us of Crowther's original Adventure game in which "you're in a maze of twisty passages..." But that was "XYZZY", not "X.Y.Z."
And, by the way, did you try to get your computer to solve this one? It's doubtful that any computer program would be able to come up with the solution. Click on Read More for some supplementary discussion on why this might be.[Read More]
1. Solve the problem (of course).
2. Identify the person in the photo (on the left), who is the problem's compositor. You can click on the photo for a full-size version.
February's entry will be what will probably turn out to be the easiest of the three, at least in terms of identifying the person in the photo; we're not so sure about the problem itself! Here it is:
Can you beat the World Champion? The clock is ticking!
(The Maven thanks Brian Hinkle for sending this one along.)
The feature problem for February is entitled The Little Fooler and is credited to Tom Wiswell and Jimmy Ricca. No less an authority than Ben Boland himself called this "a fine original problem." Skilled solver Brian Hinkle took almost a month to crack it.

These problems are provided courtesy of a gentleman named Charles, who in 2005 is celebrating his 60th year playing the Grand Old Game. He can be found on the GoldToken game site under the name NATONE. Look him up and play a friendly game or two.
Now: ready, get set, GO!

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?
