Contests in Progress:
This time of year it is our wont to observe that in the Northern Hemisphere the days are long and hot, and folks are out enjoying summer. So our August speed problems this time are most definitely on the easy side, and solving them won't cut into your pool or picnic time.
In fact, just to be sure that you have plenty of time for the summer pursuits of your choice, we're setting the time limit for these problems to a mere ten seconds. Don't blink twice, you may be too late! Click on the links below to show the problems and start the clock on your ten second solving time.
August Speed Problem One (very easy)
August Speed Problem Two (very easy)

Editor's Note: To our friends in the Southern Hemisphere, who are mired in the depths of winter, we can only point out that in less than six months the tables will be turned.
[Read More]Joshua Sturges was one of the early great teachers in the world of draughts; he published his "Guide to the Game of Draughts" in London, in 1800, and for nearly half a century it was the draughts primer. Even to this day, online bookseller Amazon lists the title in their catalog as Joshua Sturges's guide to the game of draughts: In which the theory and practice of that scientific recreation are clearly illustrated including one hundred and seventy-two critical positions. They list the date as 1881, for some reason (there were apparently numerous later editions and reprints), and note that the title is not currently available, and is not expected back in stock!
Information on Mr. Sturges isn't all that easy to come by, but we did find this historical record of a London jury that convened in July, 1801.
In the listing of jury members, a Joshua Sturges is shown as a member of the "Second Middlesex Jury." We don't know if this is the same Mr. Sturges of draughts fame, but given the date and location, it is certainly quite possible.
But today, in our continuing Checker School series, we're asking you to be both judge and jury of the following Sturges "situation."
W:WK19,K22,30:B12,21,K27.
Certainly, White is better off here, but demonstrating the win makes all the difference, and it will certainly require care and attention.
Weigh the evidence and come up with the verdict: can you prove that White wins or will there be a hung jury? After you've given it your best effort, click on Read More to see the solution, notes, and several example games, as provided by Ben Boland.
The publication date of today's article is July 14, which is the French national holiday, most popularly known here in the US as Bastille Day. The French certainly know how to throw a party, and music, dancing, liberally quaffed libations, parades, and much more take place throughout the country starting the evening of July 13 and continuing all through the next day. Capping it all off, of course, are spectacular displays of feu d'artifice--- fireworks.
We wanted to publish a French problem to celebrate the occasion, but high-level checkers as played in France is almost exclusively the international game, played on a 10x10 board with rules that differ in substantial ways from the Anglo-American game about which we write here. So instead, we're offering our own feu d'artifice display, featuring spectacular fireworks on the checker board. Here's the position, as composed by problemist T. Duncan.
W:W8,K11,K15,18,22:B4,9,13,25,K29.
With a setup such as this, you just know something extraordinary is about to happen. Can you work it out?
There's no need to explode, of course; clicking on Read More will rocket you to the crowd-pleasing solution.
Albuquerque, New Mexico, is perhaps an hour's drive south on Interstate 25 from our Santa Fe offices. We go there frequently, and with our eye for the unusual, we've spotted some rather unique combinations during our visits.
Where else will you find a Mexican-Greek restaurant?
Or a muffler repair shop that also houses a Vietnamese lunch counter?
It's not possible to top either of these eclectic melanges, but our checker problem today is a combination of a different sort.
For the sake of variety, on the first Saturday of each month we've alternated between speed problems and stroke problems. This time, we present a single problem that has aspects of both: you'll need to find the winning stroke in a rather short amount of time. The problem is fairly easy, and we think fifteen seconds should leave you with time to spare.
Of course, we're as infamous for our diabolical notion of "easy" as our Javascript clock is infamous for its unforgiving nature. But in any case, combine speed, clear thinking, and accurate play to solve this month's speed/stroke problem.
When you've worked it all out, click on Read More for the very pleasing solution paired with the actual game from which the position arose. Though we can't offer you tacos, gyros, a new muffler, or Vietnamese noodle soup, we do think you'll enjoy today's problem.
Who among us has not read The Autobiography of Benjamin Franklin, and derived untold benefit from the eminently practical wisdom and philosophy of its author? And who would be surprised to learn that Ben Franklin was himself a checker player, who praised the merits of the game as training for life?
Today's Checker School problem, though, was composed by a different Benjamin: E. A. Benjamin, to be precise, but we think it's as practical and useful, at least in checker terms, as Ben Franklin's advice for living a successful life. The problem situation is shown below.
B:W28,K9,K4:BK20,19,3.
Taking a closer look, we see that White has a material advantage, having two kings to Black's one, but Black's mobility is clearly superior. Is it enough to turn the situation into a Black win? Try it out, and then click on Read More for the solution, notes, a sample game, and some words of wisdom from the better-known Benjamin.
In the Northern Hemisphere, it's now officially summer; and what is better in summer than, at a picnic or outdoor gathering, to play a few games of checkers? A cool drink, a slice of watermelon, and a friendly contest or two over the board ... that's life at its best. At least, it usually is....
In today's column, we join Billy (we've already met him in one of our earlier stories), who is off for a month at summer camp. As one of the top players on his school team, Billy has become a sort of informal checker instructor. It's mid-afternoon, and the boys, having just finished a somewhat rowdy game of leap frog in a nearby field, have gathered at a picnic table and are settling down to some checker work.
"Here," said Billy, "let me show you guys one that's kinda like playin' some more leap-frog." He then set up the position below.
W:W19,22,26,30:B10,13,17,K27.
"Can ya believe it," Billy continued, "White can win this here one!"
The rest of the boys were talking among themselves, expressing more than a little skepticism. "But it don't look so good," objected Willy, one of the younger and less experienced players. "I mean, Black's got a king and stuff!"
Just then Mort arrived with a big plate of watermelon and a tray of sodas. He had been last at leap-frog and so was made to "go fetch" for the other boys. "Well," Mort exclaimed, glancing at the checkerboard as he set down the refreshments, "I ain't so good at leap-frog but I can win that game there!"
The words "yeah, right" were heard repeatedly as the gang attacked the food and drinks. "I can too!" Mort said in a loud and exasperated voice. "I'll show ya!"
Billy sat back a little, put down his soda, and said to the other boys in a firm tone, "Hey guys, give 'em a shot at it." This was accompanied with a bit of a wry grin that Mort didn't catch. "Tell ya what. If he figgers it out, somebody else gets the next tray of sodas. If he don't get it, maybe he needs a bath or somethin'."
Everyone started to laugh except Mort, who realized now that if he didn't find the solution, he was probably going to get summarily tossed into the lake. But there was no turning back. Shaking just a little and hoping the boys wouldn't notice, he sat down at the board.

We found this problem in a old and rather eclectic checker book. The author, who must have been an eclectic character in his own right, referred to the solution as "a real eye-popper."
You may or may not agree--- after all, what constitutes an eye-popper is in the mind of the beholder--- but we do think you'll enjoy solving this one.

Forces are even, but Black has a weak man that White can pick off in just a few moves. Can you focus on this one and see your way to a Black draw?
Don't be blinded by the seeming difficulty; clicking on Read More will provide 20-20 hindsight by bringing you the snappy, perhaps even eye-popping, solution.
No, we're not talking about the well-known Lutheran hymn, based on the beautiful aria from J. S. Bach's cantata, BWV 80, "Komm in mein Herzenshaus," although that too would make a wonderful topic if this were other than a checker column.
Instead, we're talking about a "checker fortress" as featured a little while back in Brian Hinkle's challenging Bear Claw problem (click here to review). This problem genre was once treated by Ben Boland (are we surprised?) in one of his many books.
Today, armed with the knowledge gained from Brian's problem, see if you can break into the fortress by solving these three problems. Perhaps you might wish to play some of Bach's immortal music in the background, for the purpose of relaxation, as solving these will be anything but easy.

This week we return again to Willie Ryan's Tricks Traps & Shots of the Checkerboard, a checker classic if there ever was one, and arguably one of the Bronx Comet's best works. Here's one that Willie calls "basic" from the Laird and Lady. We're not sure just how basic it really is, but let's let Mr. Ryan tell us all about it.
"The ancient and intricate Laird and Lady opening is chock-full of mid-game pitfalls, some of which defy detection by the sharpest eye. Featured here is one of the basic snares encountered on this opening, which has claimed numberless victims of varying skill. The trap is generally credited to William Reid, but it was probably known to Andrew Anderson, who was first to probe the opening extensively.
11-15 | 23-19 |
8-11 | 22-17 |
9-13 | 17-14 |
10-17 | 21-14---A |
15-18 | 19-15 |
4-8 | 24-19 |
6-10---B | 15-6 |
1-17 | 25-22 |
18-25 | 30-14 |
2-6 | 29-25 |
13-17---C | 25-21 |
11-16---D. |
See the diagram.
W:W14,19,21,26,27,28,31,32:B3,5,6,7,8,12,16,17.
A---Forms the Laird and Lady opening, so named by Andrew Anderson, of Edinburgh, Scotland, first Champion of the World, who did much to develop and popularize this complicated debut.
B---Considered the easiest line for black to handle. Of course, 11-16 would be suicide since with 26-22, 16-23, 15-10, 6-15, 25-21, 18-25, 27-4, white would win.
C---Certainly a very natural move, but it's a dead duck. The correct moves are: 11-16, 26-23, 6-10, 28-24* (25-21, 10-17, 21-14, 7-10 wins for black), 10-17, 24-20; at this position, 8-11, 19-15 results in a draw, but 7-11 loses to white, who proceeds to win with 25-21, 17-22, 19-15, 11-18, 20-4.
D---Into the whirlpool, but black's predicament is hopeless. Black cannot take the shot via 5-9, 14-5, 11-16, 21-14, 16-30, as now the boomerang by 14-10, 6-15, 31-26 ends all. Again at D, if black tries 6-10, white nails the win with 27-23, 11-16---E, 28-24, 16-20, 32-28, 20-27, 31-24, 8-11, 24-20, 11-15, 19-16, 12-19, 23-16, 15-18, 16-11, 7-16, 14-7, 3-10, 21-7, and black is through.
E---Or 11-15, 28-24, 8-11, 32-28, 3-8, 24-20, 15-24, 28-19, 11-15, 19-16, and black is doomed."
We'd certainly call this a harder than average problem, but don't let it rock your socks. Clicking on Read More will ease your ride by bringing you Willie's solution.
