How good are you at geometry? Does the problem above look easy to you? To us, it looked easy in principle, and we didn't need more than a minute or two to come up with a set of equations to represent the relationships in the diagram. Then we went to solve the equations for the desired variable 'x'. That too was just the work of a couple of minutes ... until we ran into what we'll call "a little snag."
Hopefully today's checker problem will be the work of a few seconds (not even minutes), just a brief summer interlude, with no hidden snag. Let's have a look.
You've probably already solved it, but we'll extend an extra incentive to click on Read More: We'll also give the answer to the math problem.[Read More]
It's not often that The Checker Maven presents a political message or takes a political stand, but as we prepare to celebrate the birthday of our great nation on our wonderful 4th of July holiday, we can't help but wish for unity among us.
In our Republic, Americans are free to differ and indeed we celebrate our differences. But the kind of divisiveness we've seen over the past year or so is good for no one. Why can't we agree to disagree about some things, but still unite for the sake of our nation?
The 4th of July is an appropriate time to reflect on the fact that we are one nation and one people, e pluribus unum, from the many--- one. Let's work together for the good of us all.
And for our checker problem today, we've simply got to turn to Tom Wiswell, that great problemist and great American patriot.
Can checkers be a great unifying factor? Why not? Try out this problem and then click on Read More to see how to do it. The solution is one worthy of a master; maybe you might enjoy getting together with your checker friends--- regardless of anyone's political views--- to work it out.[Read More]
We found the above inspirational poster very appropriate to our weekly column, for doesn't checkers mirror life in so many ways? Trust in our abilities, a belief in our capacity to succeed and to do what we have to do; these attributes apply both to the game of checkers and to life in general.
Someone who has Dunne-it before and now has Dunne-it again is our old checker friend, F. Dunne. We've seen his studies and positions before, and today we have another one that is subtle and interesting. It's our Checker School entry for this month.
Can you solve this and find the White draw? There's another inspirational saying from none other than Henry Ford: "Whether you think you can or think you can't, you're right." Trust in yourself, think positive, and click on Read More to see the solution, sample games, and explanatory notes.[Read More]
From one corner to the other, boxers chase their opponents, hoping to land the winning blow. The fighter above seems ready to come out of her corner and do whatever it takes to lay out her opponent.
But some fighters win by decision rather than the quick knockout. That fact, and the title of today's column, provide broad hints toward the solution of the problem shown below.
Before you begin, let's make note of a couple of things. First, White has two kings more or less entrapped in or near the Black double corner. Second, White has a man on 12 that is immobilized. Finally, White holds a bridge position on 29 and 31, but the man on 29 is immobile, and if White moves the man on 31, Black can stop it with 15-19 and then win it a few moves later.
So what can White do? Not much except perhaps shuffle around in the double corner. Black has a tremendous mobility advantage. That usually spells a win. The question is how to make it happen.
We'll repeat our hints. This is not a quick knockout; to win, Black must patiently apply technique. And again, keep in mind the title of our study. It's by no means an easy fight. This one is championship class.
Don't let this one knock you out; win the decision, then land your mouse on Read More to check your solution.[Read More]
One of Great Britain's most famous landmarks, London Bridge, has changed a lot over the years. The sketch above depicts London Bridge as it supposedly looked near the end of the 17th century. It's a far cry from today's London Bridge, and we suspect that's just as well.
One thing that hasn't changed over the years, though, is the Bridge Position in our game of checkers. Certainly, more variations and interesting problems have been published, but at heart a bridge has the same fundamental characteristics as ever.
Of course, sometimes a bridge is a win, sometimes a loss, and oft-times a draw. It all depends. In the following position, a rather unornamented bridge turns out to be a loss for the bridging side.
Is this a bridge that you can cross, by finding the Black win? We'd rate the difficulty as medium; if you're familiar with bridges, you won't have any trouble with it; and if you're not familiar with these positions, this is a good time to bridge that gap. When you're ready, click on Read More to see the solution.[Read More]
We didn't think they could do it, but our intrepid Research Department managed to come up with another meaning for the word stroke, to wit: at a stroke, with the meaning of "all at once," such as, "we solved a dozen checker problems at a stroke."
That would be quite a feat, indeed, and of course you just know we're going to present a stroke problem to kick off the month of June.
Can you solve this one "at a stroke" or will it take you longer? Are your powers of visualization up to the challenge? If you find the position difficult, we refer you to the quote at the beginning of the article.
When you've determined the correct moves, clicking on Read More will bring you to the solution--- at a stroke.[Read More]
We can bet that this woman has a pretty interesting tale to tell about installing a sink trap. It can be a messy job and a lot of things can go wrong. But it appears she's found a solution in the form of long-lasting plastic components.
Which, of course, brings us to our subject: finding a solution, not for drain problems, thank goodness, but for equally perplexing checkerboard conundrums.
Today we're continuing with our presentation of material from Willie Ryan's fascinating Tricks Traps & Shots of the Checkerboard with the first part of something Willie calls A Trap With a Tale. We know you'll find it interesting, as we've discovered some unique things about this study. We'll give the runup without Willie's notes; those will come in later columns, but for now we want to cut to the chase.
This one is not so easy and correct play requires what was once called "sticktoitiveness." Can you tell this tale or will you remain trapped in erroneous play? Patience is the watchword. When you're ready, clicking on Read More will indeed tell the tale in the correct manner.[Read More]
We quickly found out that "Subkow" is one way to transcribe a Russian name that is sometimes rendered as "Zubkov" or "Zoubkov". Since the "S" and "Z" sounds are clearly delineated in Russian, we can only think that here is another story about fanciful transcriptions done by monolingual Anglophone immigration officials who just wanted to write something down and be done with it.
In any case, there are perhaps a half-dozen Subkows in the U.S., and it's quite likely that one or more are related to checkerist William Subkow, who is credited with the following problem circa 1930 or so. It's our Checker School entry for this month.
You'll see right away that Black doesn't have much in the way of good moves; that's never a favorable sign. In fact, we'll give you a hint of sorts: There is only one initial move to draw, and that's no transcription error. The solution is a bit on the long side, but it's quite logical, although there are a couple of interesting ways to go wrong for both Black and White.
Can you find the right moves and transcribe them properly, in order to better check them after you click on Read More? That will take you to the solution, several sample games, and detailed explanatory notes.[Read More]
Spring is coming around in the Northern Hemisphere and perhaps, if you've had a long winter, you're thinking about re-engaging in the outdoor life. There's much to do in the great outdoors and every reason to take full advantage.
While today there's a commercial magazine called Outdoor Life, almost a hundred years ago there was another called The Journal of the Outdoor Life, published by the National Tuberculosis Association. We found it to be quite an interesting general readership journal, promoting the idea that fresh air is good for tuberculosis patients. Of course, medicine has advanced enormously in the last hundred years and some of the ideas in the Journal definitely seem quaint.
Interestingly, the Journal also had a "Games and Indoor Sports" section which contained some excellent checker material. Featuring checkers was fairly common back in that day, but alas, that is no longer the case.
In 1920 The Journal of the Outdoor Life published the following doozy.
Unless you have a sharp pictorial memory, this is not one to solve on an outdoor hike or while sitting around the campfire. Do it at home, after your outdoor activities are over for the day or weekend. You'll definitely need to concentrate and employ your powers of visualization, although the problem is certainly no more difficult than the "medium" category.
When you've finished, camp out on Read More to verify your solution.[Read More]
On the first Saturday of the month we often have a speed problem, an easy problem, or a stroke problem. Today we have a (not so) easy problem.
This one in a way is in two parts. There's the easy part in the beginning, and chances are you'll see that right away, even though White is on the verge of losing a piece. But then there's the second part. You'll see what we mean when you work on solving it. In any event, this little study is a great demonstration of an important winning technique.
Will you find a winning way easily or (not so) easily? This week, we suggest you take as much time as you need, and then click on Read More to see the solution and explanatory notes.[Read More]
