Checker School: All Kings

20230802-mountain.jpg

The picture above shows the Battle of Kings Mountain from the American Revolution. It was a common thing back in the day for battles to involve locations named for kings, be fought under kings, and at times even fought by the kings themselves. A battle of kings is certainly common in our game of checkers, and in this month's Checker School column, we look at a massive battle of five kings against four.

That would seem to be simple, wouldn't it? After all, the side with five kings has greater forces and ought to win. But it may (or likely may not) surprise you to know that many untrained checker players have trouble with two kings defeating one, and absolutely no idea what to do with three kings against two, let alone the larger arrays of four against three or five against four. You have to know what you're doing and in the larger settings patience and technique make up the order of the day.

Here's a five against four situation. Are you up to winning it?

Maybe

20230621-wld.jpg

There's an old adage that when a politician says "yes" it means "maybe" and when a politician says "maybe" it means "no." There's a ring of truth to that, unfortunately.

Would that politics could be like checkers. When you win, you win. When you draw, you draw. And when you lose, you lose. There's no "maybe" about it.

But take a look at this position. It's not quite a "speed" problem but an experienced player will solve it quickly.

Contest 69: Kingless Draws

20230621-20230531-ckingless.jpg

The picture above represents what we suppose to be the components of what the seller calls a "Crowned Kingless Table Lamp." We have no idea what that means. The seller was asking a high price, so this must be something quite in demand in whatever circles Crowned Kingless Table Lamps have currency.

In our game of checkers, however, "kingless" has a different meaning, although we won't even try to associate "crowned" in this context. Bill Salot brings us once again a series of kingless problems in his latest problem composing contest, #69 in the series. A unique feature is that all of the positions are drawn when properly played.

As a nice example, here is a problem called Hot Spot, composed by Roy Little. It won 2nd place in Contest 45 a few years back.

A Tricky One

20230404-tryky2.jpg

The magician above is indeed full of all sorts of tricks and we might well call her a "tricky one" although likely she would rather be known by the more formal designation of prestidigitator.

Often in the early part of each month we present a "speed" problem--- something for you to solve as quickly as you can. Such problems generally fall into the "easy" category. Today, though, we have a "tricky one" sent along (with analysis) by regular contributors Lloyd and "Gosh Josh" Gordon of Toronto. Is it as full of tricks as the magician above? You'll have to decide for yourself.

Although the problem terms are for White to find the draw, see if you can also hold the draw for Black. Unless you're an upper-level player you may not solve this one speedily, but some effort will be well rewarded.

Changing and Exchanging

20230328-changing.jpg

When traveling abroad, do we change currency or exchange currency? Or do we change currency at a Currency Exchange? We can probably say that's all a matter of semantics.

Not so much so, though, in our game of checkers. If you solve the twin problem below, sent to us by regular contributors Lloyd and "Gosh Josh" Gordon of Toronto, you'll see what we mean.

More Pictures: Problem Composing Contest 68

20230319-2many.jpg

Is there such a thing as too many pictures? Evidently so. The photo above shows an art display that hardly accords with accepted practices. It's overcrowded and the pictures aren't well positioned.

The previous entry in Bill Salot's outstanding series of checker problem composing contests featured problems that had a visual aspect--- they were works of art in both the visual and ludological senses. For our current contest, Mr. Salot has continued with that theme. Too many pictures? Hardly! We're sure everyone will welcome this new trio of dual-artform problem settings.

The contest problems themselves can be found, as always, on the contest page. We hope you'll drop by, give the problems a try, and of course cast your vote for the one you like best.

As a lead-in, we present a problem by the late Roy Little, which he called Mr. X. It was the winner of Contest 11 back in June, 2013.

Pictures At An Exhibition: Problem Composing Contest 67

20230115-paae.jpg

Pictures at an Exhibition, composed in 1874 by Modest Mussorgsky, was originally a suite of ten piano pieces linked together by a "Promenade" theme, intended to represent the experience of walking through an exhibition of the paintings of artist Viktor Hartmann at the Imperial Academy of Arts in St. Petersburg, Russia. The compositions were orchestrated in 1922 by Maurice Ravel, and this is the version that is most well known today.

We have something similar in checkers, and in this, the 67th Problem Composing Contest sponsored by Bill Salot, we'll see an exhibition of checker art that is visual as well as artistic in play quality. To illustrate this, here is one that Bill calls WreckTangle and credits to former World Champion Alex Moiseyev, who created it independently. However, it happens that Ed Atkinson was the original composer; he called it Pandora's Box.

Bill notes that there are other famous images on a checkerboard, such as the Picture Frame arising from games in Boland's Famous Positions, Page 187. Bill goes on to remark that there are numerous other patterns published in various checker problem books.

In this month's contest, Bill features three "art works" so to speak (alas, not ten as in the original "Pictures at an Exhibition"). They can be found on the contest page. Be sure to try them out and then vote for your favorite.

The solution to WreckTangle (or Pandora's Box, if you will) can be seen (after you've tried to solve it, of course!) by clicking on Read More. We hope you enjoy it and all of the contest problems.20050904-symbol.gif

Hopper: A Speed Problem

20230115-hopper.jpg

It's quite early for the Easter Bunny (Easter 2023 is on April 9) and somewhat late for Chinese New Year and the Year of the Rabbit (January 22). So let's look at a little math problem instead:

"Chris is training Hoppity, her pet rabbit, to climb stairs. It will hop up one or two stairs at a time. If a flight of stairs has ten steps, in how many ways can Hoppity hop up the this flight of stairs?"

Oh, wait, this is a checker column. Well, in fact regular contributors Lloyd and Josh Gordon have sent along a "speed" problem they call "Hopper" so it seemed like something about a rabbit would be an appropriate lead-in. And no, the problem has nothing to do with the late GAYP master Millard Hopper.

The problem itself is a lot of fun, and of course the layout of the pieces, not to mention the problem's title, give a huge hint. It's certainly not a hard problem and can be quickly solved with just a bit of visualization. As we're fond of saying, top players will see it at once while the rest of us may require a few more seconds, or maybe even a minute or so.

Quick As a Bee

20221211-fastbee.jpg

You're likely familiar with the phrase, "quick like a bunny" or "quick as a bunny" meaning, in its imperative form, to tell someone to do something very rapidly. However, that phrase is relatively recent, dating back to only the 1940s according to most sources.

"Quick as a bee" has the same meaning, but is much older; 400 years older, to be exact. It appeared in John Heyward's Proverbs back in 1546. So for today, we'll weigh in on the side of history, and ask you to solve this month's speed problem "quick as a bee." In fact, it's quite easy, and an experienced player will see the solution in about two seconds. Novices should eventually get it as well.

Chases: Problem Contest 66

20221122-foxhunt.jpg

The chase is on! The traditional fox hunt, now very much out of favor and considered cruel, has for the most part become illegal, and although especially in England it's a centuries-old amusement for the wealthy, perhaps indeed its time has passed.

But in our game of checkers, the chase is alive and well, and forms the theme of the 66th in Bill Salot's long and outstanding series of checker problem composing contests.

Mr. Salot states that, as in the preceding contest, these original, unpublished, strategic dandies are non-strokes, although a shot may ring out occasionally during a wild "chase." Four new problems await you on the contest page. Be sure to try them all and then don't forget to vote for your favorite.

Here's a teaser problem showing off the contest theme. It's by the late grandmaster composer Ed Atkinson, and it's typical of his genius.
