The picture above dates to World War II, when many did without in support of the war effort. Luckily, today, in the free world we generally don't have to do without, as a minimum, the basic necessities.
In checkers, there is "doing without" as well; in today's study, the winning side has to make do without "the move." This is called in textbooks, logically enough, "first position without."
We know that first position is a win with two kings against a king and a man, as long as the side with two kings has the move. But checkers is full of subtle twists, and there are wins in some of these positions without having the move on the stronger side, hence the name "first position without." There are supposedly twenty or so of these exceptions to the general rule. Below you'll find one of them.
There are a couple of ways to do this, depending on how White plays. One of them is as proposed decades ago in Dr. Call's book of "Midget" problems. Another line is preferred by our KingsRow computer engine.
Can you find the win here, or will you have to do "without"? See how you do, and then "without" hesitation, click on Read More to see the solutions.[Read More]
March is over and April has come around again, as it always does, with perhaps a promise of spring. This column is being first published on April 1, 2017, and you might do well to bear that in mind as you take a look at today's checker problem.
We rate this one as very easy. You can solve it in seconds if you get the idea. But it's almost surely impossible if you don't see what's going on.

In a recent article we asked you about your preferences in board diagrams, and although there were various opinions, a clear (and nearly overwhelming) majority seem to prefer black and white diagrams with the corresponding side notations of "Black" and "White." So, as of today, we're switching over. A good picture is indeed worth a thousand words.
The problem is that we didn't think the black and white diagrams were of especially high quality. But we're happy to say that we've found a way to "port" the excellent black and white diagrams used in our print publications over to the web. We'll spare you the technical details, which involve rather arcane Linux knowledge, and instead hope that you like our new, larger, clearer diagrams. Do write and let us know what you think.
So, let's start off with a fine problem from Samuel Gonotsky. This one is taken from over the board play and it's quite a nice early endgame study.
Against best play by Black, White will have to work pretty hard to get the draw. Situations such as these are seldom pure black and white. Can you find your way through? Our computer found a neat move to make things much harder than we think Mr. Gonotsky intended, but that's the black and the white of it.

The young fellow above seems to be having some trouble with his lesson, at least judging by the state of the blackboard, the look on his face, and the number of books piled up beside him. Could those possibly be checker books, and might the bottom one be a library edition of Complete Checkers? We can't say for sure, but one can always hope.
In today's Checker School entry, we present a little lesson with a big payoff. The position is shown below.
What can White do here? The man on 17 is doomed and apparently White can only shuffle his king around and wait to lose. Yet there is an astounding draw here, one most worthy of the Herd Laddie. We call this a "little lesson" because Ben Boland was unusually brief in his commentary and there is only one sample game. Nonetheless we're certain you'll love this study, which is now approaching 150 years in age.

The above quotation comes from the popular television series Downton Abbey, and surely it rings true for life in general.
But for our game of checkers, we suggest that the situation is different, and bringing to light unpublished play is sometimes instructive and revealing.
That's the case today, as we conclude our extended series on the Kelso taking from Willie Ryan's famed Tricks Traps & Shots of the Checkerboard, with something Willie calls "a fine unpublished variation."
Let's first give the entire run-up, without commentary.
The critical position. Willie gives the following spectacular clearance as his main line draw:
But let's go back to the diagram. Willie says, "If 9-13 is played, 14-10, 7-14, 15-10 will be good enough ..." and certainly after 2-7 22-15 the draw is on the board. Now, Willie goes on to claim: ... if 16-20 is selected, the following leads to a draw: ..." and then he gives J. P. Murray's previously unpublished variation.
So, from this position:
can you find the White draw? This isn't especially easy, but what's interesting is that there are actually two drawing moves for White, one of which the computer discovered ... perhaps a whole new unpublished variation?

We've often said that we present a range of problems in our Checker Maven columns; sometimes they're grandmaster tough, sometimes beginner easy, but most are usually somewhere in-between. We have readers with a very wide range of skills, and we try to provide something for everyone. We suggest the following: when you find a problem is tough, study the solution with a view to learning technique; when it seems easy, try for rapid sight recognition.
Today, though, we've got a truly easy-as-pie problem that even many early-stage checkerists will solve right away. See how quickly you can spot the solution!
By the time you read this line, you've probably already solved it, but just in case, you can ease over to Read More to check your answer.[Read More]
If you live in a cold North American climate, you probably can use a bit of a winter break. Now, there's a definite difference between a winter break--- an escape from the cold--- and a spring break, which is often associated with hijinx on the part of college students.
But we think a winter break can also stand a bit of mischief, at least of the checker nature. So we've chosen a problem that was originally titled "Maryland Mischief." Surely, Maryland can suffer from some serious winter weather, and perhaps this is a Marylander's way of taking a break. Have a look and see what you think.
Attributed to a Wilson Coudon of Elkton, Maryland, you can tell you're in for some mischief from the problem terms alone, as it's one of those "What Result?" puzzlers that often leave you guessing. That diagonal lineup looks pretty mischievious, too. Perhaps the fact that White is down a piece will provide a clue?

The British train known as the Transpenine Express certainly goes to Leeds, but the title of today's Checker School column deals with a position first published in an old newspaper known as The Leeds Express.
Surprisingly, our intrepid research department didn't turn up very much on this publication, which obviously enough once featured a draughts column. The most likely candidate is the Leeds Evening Express, published by Frederick Robert Spark starting in 1867. Today, there is a Leeds Express published by Johnston Publications, a major British publisher of local and regional newspapers. There was also the Skyrack & East Leeds Express, later called the Leeds Skyrack Express and then Leeds Express, which ended publication in 2002. But given the date of today's study, we'd stick with the Leeds Evening Express as the source.
Confusing? Unraveling publication histories is at times as difficult as solving a challenging checker problem. Now, the position below may not be the toughest ever, but it too surely requires some thought.
Can you unravel this one? We ourselves had some serious unraveling to do, as you'll see when you click on Read More to see the solution, notes, and a sample game.[Read More]
We're trying out some of these ideas today. By eliminating the clock, of course, we eliminate the timed challenge and in a way negate the idea of a "speed" problem; the idea will be to simply see how fast you can spot the solution, without any external pressure.
The reader also suggested that since our diagrams show Red and White pieces, we should discontinue use of the term "Black" in favor of "Red." That's a bit more complicated, in that much of the literature we quote uses the terms "Black" and "White." In our early days, we indeed used black and white diagrams, but the red and white proved much more popular.
What to do? Red or Black? Le rouge ou le noir? For now, we're continuing with Black rather than Red, but we'd love to hear your opinions. Write to us at firstname.lastname@example.org.
But let's go ahead and look a typical speed problem. Black (Red) is at the bottom of the board, moving up, and the terms are Black (Red) to play and win. There's no clock and so no particular time limit. We've also provided both a Red/White and a Black/White diagram. Which do you prefer?

Grandmaster Richard Pask's crowning achievement, Complete Checkers, is now available in electronic and print editions. We are proud to say that Mr. Pask once again gave us the honor of editing, typesetting, and publishing his latest work.
Combining all seven sections of 21st Century Checkers with much new material, including guides and indices as well as play revisions and enhancements, the book extends to over 730 pages, with 200 diagrams and some 2,200 complete games. It will be the definitive guide to 3-move ballot play for decades if not generations to come. Mr. Pask has built on the work of the great players and masters, applying his own vast knowledge and expertise, and employing powerful modern computer engines to validate and extend the analyses.
The result is incomparable, and due to Mr. Pask's generosity, the electronic edition is yours as a completely free PDF download. Just go to the Richard Pask page, as linked in the right-hand column. It was our mutual desire that the book be available to everyone, everywhere, without barriers caused by financial limitations.
But, means permitting, you may likely wish to have a print copy. The print edition is perfect-bound with full-color covers and can be obtained from Amazon or CreateSpace as well as Amazon UK and Europe sites. It is priced very modestly at $24.99 in the US. We put a lot of care into the print edition and we think you'll find it a great addition to your checker library, providing you with years of high-level study material.
Now, just to get you going, here's a position from some of the new material Mr. Pask added to this edition.
There is more than one way to do this, but the differences are in the details rather in the basic principles. The solution is a bit long and you may not find it easy, but we'll give you a broad hint: think about achieving a simpler, known winning position.
