For many years, checker problem legend Bill Salot has been running a series of checker problem composing contests that he calls the "Unofficial World Championship." There have been no less than 55 of these contests and they have seen the publication of a host of quality contemporary compositions, many of which indeed stand in the world-class category.

To date these competitions have been hosted at the American Checker Federation (ACF) website. But over the past few years the ACF website has fallen into a state of neglect, and no longer provides a viable hosting venue. So when Mr. Salot approached us to take over the contest hosting, we happily accepted in the interests of ensuring that these fine competitions would continue into the future as well as reach a wider audience.

Today we proudly host Contest 56 and you'll have not one but three sparkling problems to contemplate. You can access the competitions, now and in the future, at

Mr. Salot asks that you be sure to vote for your choice of winner after you've studied all the problems. More information is available on the contest page.

Please enjoy this new Checker Maven feature, brought to you by Bill Salot and some of the best contemporary checker problemists.

Prize increased to $100!

In checkers we think of a "prize problem" as one that is so good it has won a prize of some sort, presumably in a problem composing contest. But today we have a prize problem that gives a prize rather than wins one--- although we think it's more than good enough to take the prize in many a contest.

Brian Hinkle offers $25 to the reader who is the first to correctly solve the following problem.

Is it difficult? You bet it is, and it will require much skill and board vision to work it out. Go ahead, give it your best. Set it up and move the pieces around.

We'll publish the solution on June 5 (Note: this has been delayed due to the increased prizes) and announce the winner (if there is one, and if the winner agrees to have his or her name and location published). The prize won't be awarded if no one solves the problem correctly.

Brian also asks you to help give a name to this problem. He's called it simply "Prize Problem" but wonders if there is a title that might be more thematic. Send your solutions and name ideas to Brian by emailing sbhinkle@charter.net.

Unfortunately in today's legal environment there are some additional terms and conditions. Please read them carefully.

Void where prohibited by law. Taxes, if any, are the responsibility of the winner. The composer, Brian Hinkle, is the sole judge of the correctness of submitted solutions and his decisions are final and without appeal. All correspondence and solution attempts must be sent to sbhinkle@charter.net. Do not send solutions or questions to The Checker Maven. All solutions and suggested problem names become the property of Brian Hinkle and The Checker Maven. If you submit a solution or correspond with Brian, you understand and agree that Brian will then have your email address and possibly your name. To receive the prize, the winner must provide Brian with a postal mailing address. Brian pledges that email and postal addresses will be used only for the purposes of the contest and will not be disclosed to any third party unless a legal obligation to do so arises.

Good luck to one and all!

Rebound. With the literal meaning of "bouncing back" the term applies to a number of things. There's the rebound in basketball. Someone recovering from an injury or illness can be said to be "on the rebound." And of course there's always the "rebound romance."

"Rebound" is an apt title for today's Checker School column. You'll see why when you solve it.

This one is probably around medium in difficulty. You may not get it on the first try, but we're sure you'll "rebound" from any such small setbacks and find the solution. When you've either figured it out or bounced around enough, click on Read More to bound over all barriers and see how it's done.

April. For much of North America, winter is coming to an end. There's more daylight. Compared to the winter months, it's an easy month. Well, mostly. In both the US and Canada, income tax returns come due. Kind of spoils the "easy" theme, doesn't it?

On the checker front, though, we'd like to ease into April, even if April isn't completely easy. Here's a speed problem sent to us by regular contributors Lloyd and Josh Gordon of Toronto. It's very much on the easy side. An experienced player will solve it in a few seconds; a beginner might take a little longer, but not a lot. At the Checker Maven we try to provide something for everyone.

Okay, maybe too easy. So now try this one, also based on a position sent by Lloyd and Josh.

Black has just played 1-5, whereas 1-6 or a couple of other moves would have held a narrow draw. Yes, this certainly looks like a White win, but it's a good exercise in application of technique to work out how it's done. Not nearly as easy as our first problem, but straightforward enough.

An easy start to April, or a harder one? You be the judge. Solve the problems and then it's easy enough to click on Read More to check your solutions.

Yosemite Sam, the arch-enemy of Bugs Bunny, is famously known to exclaim, "Jumpin' Jehoshaphat!" but it's not likely that the said toon character was aware of the origins of this expression.

Indeed, there isn't a lot known about the phrase, except that it first appeared in print in 1866 and is thought to be part of the 19th century predilection for "minced oaths" which embodied a strong expression of feeling without actually using potentially offensive words. Other efforts to relate the expression to the biblical Jehoshaphat seem to us to be somewhat forced.

In today's Checker School column, taken from Andrew J. Banks' unusual and instructive book, Checker Board Strategy, we meet a "Jumpin' Jehoshaphat" checker problem. You'll see what we mean when you solve it.

Jump to it! Solve the problem and then jump your mouse over to Read More to verify your solution.

What's easy for some isn't quite so easy for others. The math above is quite simple if you happen to be a Ph.D. mathematician. If you struggle with high school algebra, you may not find it all that easy.

Regular contributors Lloyd and Josh Gordon sent us a checker problem which illustrates this concept rather well. Take a look at the diagram below.

Is this problem easy? For a player with a little experience, it's pretty straightforward. For a novice, it might be harder and take a little more effort. While we're calling it a "speed problem" we won't specify a time limit. Solve it as quickly as you can.

What's easy for anyone, though, is clicking on Read More to see the solution.

We think the title photo speaks for itself. This cute little one certainly seems to be up to something.

Today we have not one but two speed problems. The first one is very easy but quite cute.

The second problem is a bit harder, but not much.

This problem could just as well have had the terms White to Play, Black to Draw. It's not at all difficult but it has a nice tricky little twist. You'll see what we mean when you solve it.

Are you tricky enough to solve a cute problem? (We won't ask you the implied inverted question.) When you've found the solutions, click on Read More to verify your solutions.

Our heroine above is dangling above --- well, we don't know what. A bottomless ravine? A pit filled with rattlesnakes? A fiery inferno? We can only hope that she finds her way to safety.

Similar situations come up in the game of checkers. Sometimes, a piece is dangling and can't be rescued. Or it might suffer a different fate, or something else altogether.

There's a point to all this. Today's Checker School entry is a very old problem from Joshua Sturges. It isn't especially hard; indeed, it's just about a ten second speed problem. But it's very instructive and rather neat. After you've solved it, you may see why this column has the title that it does, and that "dangling" can have an alternative meaning.

The problem is found (among many other places) in the "Problems for Beginners" section of Andrew J. Banks' Checker Board Strategy. We're not sure if a complete beginner could solve it, but it's within reach of anyone above novice level.

Don't let the solution dangle; find it and click on Read More to verify your answer.

The banks of the Jordan River are fabled, from the days of biblical history right down to the present. The connection with checkers? Well, none, really, except that whenever we hear "banks of the Jordan" we think of the famous Jordan-Banks championship match, which although of biblical proportions, took place during the relatively modern days of November, 1914.

Played in Kansas City, Missouri for the then-fabulous prize of $1,000, the games were memorable and indeed commemorated in a fine match book. Let's take a look at the very first game, which was played after suitable fanfare and ceremony.

Banks had Black and Jordan had White. The 2-move ballot was 10-14 24-20.

1.	10-14	24-20
2.	11-15	22-18
3.	15x22	25x18
4.	6-10	26-22
5.	8-11	27-24

The game continued from here and went on to an eventual draw, as might be expected. But what if White had played 5. ... 28-24 instead? Would that have been a mistake, or just one of several alternatives?

5. ... 28-24 would have led to the following position.

Would Banks have been able to bank on a win in this case? Of course, Mr. Banks never had to cross that particular Jordan, but it would certainly have been interesting. See what you make of it and then cross your mouse over to Read More to see the solution.

This column will appear on December 26, 2020, and we hope you are all enjoying the holiday season. Whatever holidays you may (or may not) celebrate, we do hope this time of year will bring you whatever you may wish for, be that time with family and friends or just a chance to have a little break from the usual.

We like to draw from our favorite historical composers at this time of year, and today we turn to a prolific composer of days past, L. J. Vair. Mr. Vair originally lived in Denver and was known as "The Kolorado Kowboy." He also lived in Ohio, and in his latter years in Auburndale, Florida. Here is a problem that is said to be of a type in which Mr. Vair specialized back in the day.

This problem is bound to give you holiday cheer, even if you don't live in Colorado, Ohio, or Florida, and even if you're not a "kowboy." Take the time to work it out; it's a real pleaser. When you're ready, click on Read More to see the solution.
