Contests in Progress:
We haven't run a "stroke" problem in a little while, though it's something we like to do for the sake of variety on the first Saturday of some months. Today we return to that theme, and present a problem that was considered "easy" by the author.
Much as the photo above represents the bizarre side of architecture, stroke problems are certainly the bizarre side of the world of checkers. You either love them or hate them, and we think that depends in no small measure on whether you're able to solve them. Stroke problems call upon your ability to visualize long, forced series of moves. They are an excellent test of your skills, but seldom, if ever, an exercise in practical play.
So here's our so-called "easy" problem.
W:WK5,6,K9,10,12,19:B4,K11,K27,28,K32..
Could you find your way through, or is all simply too bizarre? Whatever your result, click on Read More to see the "easy" solution. Did we say "easy"? You may or may not agree!
[Read More]Are you celebrating the upcoming New Year's Eve on an elegant cruise ship off the coast of O`ahu? Well, don't feel bad, we're not either (though maybe some day we might). We'll likely stay home in our Honolulu location and watch the goings on from our lanai.
We'd like to present you with an alternative, though, to parties and dancing. We have a checker problem that is difficult enough to carry you through the evening and into the early hours of the morning. It's non-alcoholic, doesn't require driving or pushing your way through a crowded dance floor, and is completely free. What else can you find on New Year's Eve that doesn't come with a stiff price tag? (That's why we're skipping the cruise this year, in fact; at nearly $300 per person we'd much rather play checkers instead.)
Here is a position that even champion Tom Wiswell called "challenging."
Can you cruise to a solution this New Year's Eve, or even sooner? There's no need to wait, though; clicking on Read More will ensure a smooth voyage straight to the answer.
[Read More]In today's entry from our Checker School series, we have a most interesting position, as shown below.
B:W25,K12,K2:BK11,10,K1.
In this position, Black's mobility is definitely in the plus column. And as our current World Champion has often stated, checkers is all about mobility. In fact, Black has a very neat win here. The position is almost 120 years old and is attributed to R. D. Yates. Well over a century later we find that it still entertains and instructs. It's a fitting tribute to the timeless attraction and value of the game of checkers.

[Read More]Our title is how famed problemist Tommie Wiswell referred to today's puzzler, which he drew from actual play. It's one of those cases in which the win is "obvious" but actually demonstrating how it's done is the real trick.
W:W12,K18,22:B5,13,21.
The Black pieces are all off on the side of the board, while White has good mobility and a king to boot. So the win should be easy, shouldn't it? But Mr. Wiswell notes that in play over the board, the White player missed the winning continuation. Can you do better?

[Read More]In the United States it's Thanksgiving weekend, bringing one of our favorite times of family, food, and celebration. In the spirit of the weekend, we'd like to bring you an especially elegant checker problem which we're sure will provide you with much pleasure. It's part of our Checker School series and looks like this.
W:WK10,20,22:B1,9,28.
The problem is due to R. Martins, and while the solution is not overly long, it may surprise you; and, like Thanksgiving dinner, the problem is incredibly rich in content. Take your time, have a slice of pumpkin pie and a cup of coffee, and enjoy. When you're all done, click on Read More to see the solution, a sample game, and detailed explanatory notes.
[Read More]Willie Ryan, possibly the only checkerist ever to achieve anything close to "rock star" status, takes us back to his youth in this month's installment from Tricks Traps & Shots of the Checkerboard. Let's listen as Willie tells us about a trap he learned in those early years. Editior's note: the photo above is definitely not Willie Ryan!
"When I was just a boy of 13, I learned this trap on the Defiance opening by John Drummond, which enabled me to win more than a few games. The basic germ or idea utilized in this example is known as the "Brooklyn"--- a tactical device that has almost as many variations of application as the versatile in-and-outer.

A---The old and somewhat difficult Andrew Anderson defense. A better defense for white is: 22-18, 15-22, 26-17, 11-15, 24-20, etc., as given in my book, Scientific Checkers Made Easy.
B---To the gallows! The correct play here is: 31-27, 8-11, 18-15, 11-18, 21-17, 14-21, 23-5, 2-6, 27-23, 10-15, 19-10, 6-15, 20-16, 12-19, 23-16, 15-19, 16-11, 19-24, 26-23, ending in a draw."

[Read More]I had a bit of an argument with Mom this morning, and that's never a good way to start off the day. It was Saturday morning, and nearly every Saturday for more than a year I'd gone over to Uncle Ben's for a couple of hours, to sit on his porch, drink his wonderful lemonade, and learn something new about checkers.
But Mom had said that we're two months into a new school year, I'm in fifth grade now, and I need to spend a few extra hours hitting the books, as I hadn't exactly gotten off to a good start in English and math. Besides, she said, you can't be bothering Uncle Ben all the time; the elderly gent can't be expected to entertain children every single week!
I pointed out that Uncle Ben seemed to really look forward to my visits and that he might be disappointed if I didn't show up. Besides, I said (repeating back a few lines I'd heard from Uncle Ben himself), checkers helps a student with logical thinking and the application of reason. (I'm glad Mom didn't ask me to explain what all of that really meant, though.)
After a little while Mom relented and let me go, with a final caution to not stay too long and wear out Uncle Ben's patience or hospitality. Still, I didn't feel very good about the whole incident, and when I arrived at Uncle Ben's and sat down in one of his porch chairs, I couldn't help but blurt out the whole story.
"Well, Tommy," Uncle Ben said after hearing me out, "listening to your Mom and doing as she says is very important, and I shouldn't discourage you from doing so."
At these words, my heart started to sink and I was sure Uncle Ben was going to send me straight home. Certainly, he realized this as he added, "No, no, Tommy, I'm not going to send you off. But we need to make a little deal, one that you need to tell your mother about when we've shaken on it."
"Deal?" I said, unsure of what was coming.
"Yes, a nice gentleman's agreement. The one part of the deal is that you can come here and visit every Saturday that you wish ... but the other part is that your grades have to all be above whatever mark your mother decides. So if she says that you have to have nothing less than a 'B' in every subject, then you have to do that well in school," Uncle Ben concluded.
"But ... but ...." I stammered.
"No 'buts', Tommy! I know, you're worried that your mother will ask you to get all "A"s or something really hard. But I know your mom and I know she'll be fair about it. She'll just expect you to do your part. So, is it a deal, then?"
"Yes, sir," I said, and we shook hands on it. Uncle Ben was right, Mom would be fair, and I did want to keep my grades up, though I knew it would be hard work.
"Well then!" exclaimed Uncle Ben, "all this business talk makes a man thirsty!" And before you could blink twice, Uncle Ben had placed glasses of frosty lemonade on the table in front of us, and turned his attention to the checkerboard.
"You've been coming along fast," he said, "and so today we're going to try something a little harder. It's a bit like school; as you move up in grades, the work gets harder, but you learn more and more all the time. What do you make of this? Here's one in which whoever moves first will win."
This was the position Uncle Ben had set up for me.
W:W20,21,23,32:B1,10,12,13.
I took a long, careful drink of lemonade, and all at once, everything seemed clear. "Hey, Uncle Ben, I've got it!" I said proudly, and began to move the men to demonstrate the solution.

[Read More]The first Saturday of each month we often offer a speed problem, featuring our relentless Javascript clock, and this month we return to that theme. But today's problem might not be quite a speed problem.
To be sure, the better checkerists out there will likely come up with the solution in short order. But others may perhaps need a little more time. And so, to accommodate everyone, we're being especially generous and allowing a whole two minutes for you to find the solution before the clock runs out. Aren't we the kind ones?

November Speed Problem (moderate difficulty)
Whether you were speedy or not, clicking on Read More will show you the solution in a jiffy.
[Read More]In one of our favorite Honolulu second-hand book stores (not that there are all that many to choose from), we came across an old book that purported to contain the "hardest" problems in various genres. The book bore a very low price tag and so we decided to add it to our collection.
We weren't terribly surprised to learn two things about this book: first, that the problems were anything but "hard" for the most part, and second, that the requisite checker problem was to be found within the book's contents. The checker problem was certainly entertaining enough, but as for difficulty, we found it a suitable entry for this month's "easy" problem!
Here's the problem:
W:W15,19,21,23,26,K27:B12,14,18,K29,K30.
Think hard, though you'll hardly need to; and a good hard click on Read More will then bring you to a hard stop at the problem's hardy solution.
Editor's Note: Where's the Javascript clock this month? Well, we've decided that, in addition to our usual "speed" problems where you compete against the clock, we'd alternate some months with an "easy" problem that is suitable for those of us with, shall we say, lesser talents. There is no clock for the "easy" problems in order to allow our readers to concentrate on solving without time pressure.
[Read More]We haven't published one of W. T. Call's delightful miniatures in quite some time, so this week we provide a long overdue selection. Miniatures provide much more of a challenge than their simple settings imply; they are as much a test of visualization skills in their own way as stroke problems are in another way.
The little problem that follows relies, as you might guess from our title, on a "squeeze" theme. You'll see what that means when you've solved the problem.
B:W31,26:BK7,3.
