Contests in Progress:
Here's a double-barrel offering which combines a more-or-less "regular" problem with a quickie. Let's start here, in a position that looks very bad for the White team.
W:W13,21,25,28,29,31:B2,6,14,15,16,K23.
You can check this out any way you like and see that it's a White loss; the best try seems to be 25-22 after which play would probably go something like this:
25-22 14-18 22-17 18-22 17-14 15-19 14-9 16-20 9-5 23-18 21-17 18-15 Black Wins.
But instead suppose White tries 28-24, giving this position:
B:W31,29,25,24,21,13:BK23,16,15,14,6,2.
Can you find a Black win here? There is a move that looks like an instant win, yet, surprisingly enough, allows for a quick White draw. But that's the subject of the 'speed' portion of our problem.
First find the Black win above (there are two possible answers), and then click below to launch the speed problem and start our timer, which monitors your speed as carefully as the radar device depicted above. Click on Read More for the answers and a little about the problem's background.
We won't impose a time limit for this one; after all, we don't want you to get a speeding ticket.
Speed Problem (fairly easy)
Marvin J. Mavin, Captain of the Detroit Doublejumpers of the National Checker League, looked somewhat uncomfortable and perhaps more than a bit out of place.
The occasion was the Annual Tasting Gala of the Greater Detroit Fine Champagne Association, and Marvin had been brought to this event, despite his protests, by his girlfriend, Priscilla K. Snelson. Priscilla, who to her disliking was affectionately called "P.K." by Marvin, is Executive Vice President for Marketing at the Mighty Motor Company of Detroit. A graduate of University of Manchester and the Sloan School of Economics, she is a cultured and sophisticated businesswoman, and, well, we must admit it, rather a contrast to her boyfriend Marvin.
The waiter glared and Priscilla hissed, "Marvin, please!" Marvin, touching her arm, whined, "Aw, P.K., you know I don't dig this Frenchy stuff.... what's wrong with a nice cold bottle a Belcher's?"
Priscilla, not deigning to answer, quickly steered Marvin away from the group and in another direction. "How can you be like that," she said in a tight and clearly displeased voice. "And don't call me P.K.!"
A small, stocky man waved from the other side of the room. Priscilla brightened and waved back. "Come, Marvin," she said, "I want you to meet Dmitri. Perhaps you can try to get along with my friends?"
"Checker boy?" Marvin exclaimed, "I happen to be a top ranked professional checker..."
"Da, da," interrupted Dmitri, "checkers boy! I am myself very high rank master of shashski... shashki master can crush any silly checkers boy." (Editor's note: shashki is Russian draughts.)
Marvin was getting more than a bit red. "Marvin...." Priscilla cautioned, but Marvin had already erupted. "Listen here, Comrade Commie, hows about you put a few rubles behind your big mouth and play a little friendly game, hah!"
"How dare you insult my friend..." Priscilla began, but Dmitri interrupted, "Oh, checkers boy becoming angry checkers boy," he oozed, "da,da, we play game for one thousand dollars US, you think?"
"A thou...that's a lotta beer," muttered Marvin under his breath, and then said aloud, "Yer on, Pinko."
"MARVIN, ENOUGH!" shouted Priscilla, but he was already on the way out to the parking garage to fetch his checker set from Priscilla's Mercedes. "Be right back P.K.... er... honey," he called over his shoulder.
Fifteen minutes later Marvin and Dmitri were seated on opposite sides of the checker board, with a very displeased Priscilla standing at the side, and a crowd of onlookers, bearing champagne glasses, gathered around the table.
The play was intense, and somewhere along the line, Marvin went down a piece, with the game finally arriving at the following position.
W:WK4,K10,K13,30:B2,K19,K20,21,22.
Dmitri was clearly grinning, looking about at the crowd for signs of approval. "You see it, da? American checkers boy is down one piece. Dmitri will be winning 1,000 dollars US very soon. Will buy fine Russian vodka for all good champagne people cheering for Dmitri!"
At this, the crowd was smiling, relishing the thought of a vodka chaser to their liberally imbibed glasses of champagne. But Marvin, in contrast, looked more than a bit worried; he was fidgeting in his chair and repeating over and over, "If only I had a beer...."
Can Marvin pull this one out, as he has done in the past with so many other tough positions? Will Priscilla remain angry or will they patch things up? Will Marvin ever get his beer?
Learn the answers to these questions when we conclude the story in a month or so, but meanwhile, see what you can do with the challenging position shown above.
Editor's Note: We believe this to be quite a difficult position to work out, but we invite you to match wits with our hero Marvin and see how you do.
We thought we were done with our Masked Man series, but we came across something just too good to pass up. Here's a photo of the subject of this article:
Now for the situation:
W:W15,21,22,25,26,27,28,30,32:B1,2,3,5,6,8,12,18,20.
Our Hero's opponent made an egregious blunder a couple of moves back. The position in the diagram arose after a couple of forced trades. In the actual match, said Hero missed the win. Can you succeed where he did not? And while you're at it, can you name the man in the photo? How about his opponent? How about the year and location of the match, and the results?
We're asking a lot, so we won't tease you any further. After you've given this your best shot, click on Read More to see the solution, an animation of the complete game, and the answers to all of our questions.
Our stroke problems, we like to think, have been challenging, elegant, and charming (if we do say so ourselves), but they have had a certain artificiality in their makeup. So, for a bit of a change, we'd like to present you with one that may be of a somewhat more practical nature. At least, maybe. Or maybe not?
Here's the problem:
W:W7,K9,10,17,18:B1,3,K16,K26,27.

Having completed republication of the introductory section to Willie Ryan's classic Tricks Traps & Shots of the Checkerboard, this month we swing into the main part of the book: a compendium of situations both famous and not-so-famous. Today, we present two classics which you've most probably seen before. If so, you'll have no trouble solving them.... right?
Here's Willie in his own words.
Don Canalejas' Cannonball
Almost 300 years ago, a Spanish mathematician, Don Canalejas, pointed out the most famous of all booby traps, a five-move demoralizer. This is the first pitfall the student should learn to avoid. Set the pieces up for play. Then move 11-16, 23-18, 16-20, 24-19, 8-11---A, forming the position on the adjoining diagram.
W:W18,19,21,22,25,26,27,28,29,30,31,32:B1,2,3,4,5,6,7,9,10,11,12,20.
The Fool's Trap
Another premature opening procedure, which frequently embarrasses the beginner before he gets half started, is the Fool's Trap, another five-move paralyzer second in importance to Canalejas' Stroke. Set the pieces up for play. Then move 10-15, 23-19, 6-10, 22-17, 11-16---A, and we arrive at the situation shown in the diagram.
W:W17,19,21,24,25,26,27,28,29,30,31,32:B1,2,3,4,5,7,8,9,10,12,15,16.

The final installment of our three-part lesson on man-down draws is a triplet. In the first two settings we'll see more ways to come from behind, while in the third setting, alas, we won't be able to pull it off.... but from this we'll learn what to try to avoid.
Ever been a man down in an endgame? Not you, right? As we've said in the other lessons in this series, it happens to everyone. Saving the draw, when possible, is an important skill to master. If you're a student, study this lesson carefully. If you're an advanced player, a review of what we take to be "obvious" can never hurt!
Let's start out with this position:
Next, the famous Payne's Double Corner Draw, which should be learned by everyone who ever touches a checkerboard:
And finally, a lost opportunity, to be contrasted with the very similar-looking Payne's Double Corner Draw:

This past holiday season was filled with the usual hustle and bustle, and often stress triumphed over enjoyment. Many of us are a bit relieved, in fact, to return to the simpler, more ordinary days of the year.
Here's a Tom Wiswell problem, then, that seems to promise us the joy of simplicity.
W:WK21,28,31,32:B2,19,20,23,K30.
White is a man down but regaining it is child's play. Has the simple life arrived, and have we solved a Wiswell problem in mere seconds?
Alas, life is not easy, and neither is this problem. Can you, without too much stress, see through to the solution, and bask in contented post-holiday enjoyment?

White may be a man up, but Black has two kings and a strong position. Can you provide some holiday cheer for the White side?
In the spirit of giving, here's a hint: the natural-looking 5-1 loses. Can you tell why?
