Bad Teacher

20220326-badteach.jpg

Bad Teacher was a terrible film from the year 2011. We certainly don't recommend it, but the idea does lead us nicely into today's Checker Maven column.


LARNER TRIES TO TEACH

"This is the way," said Larner impatiently as he persisted in rapidly solving a problem without giving the boastful Skittle a trial.

Galileo once said, "You cannot teach a man anything; you can only help him to find it within himself." How could Skittle learn without being permitted to make mistakes and then correct them?

Since 1775, due largely to the experiments of Johann Pestalozzi, the science of education has been based on problem solving or reasoning, rather than on memorizing. This Swiss educationalist combined manual with mental exercises. Teachers merely develop your latent power. You learn mainly by practice!


The preceding short selection is from Andrew J. Banks' eclectic book, Checker Board Strategy. It seems that Mr. Larner, whoever he was, is an example of a bad teacher. Is it true, for our game of checkers, that we learn mainly by practice, and that teachers merely develop our latent power?

That could be the subject of an extended and interesting debate. But for the moment, let's get some practice, with today's rather easy problem. It's really at the beginner level but more experienced players should see if they can solve it with just a quick glance.

The June Bug

20220326-junebug.jpg

It's the month of June and in some parts of North America it's the "June Bug" season. The June Bug is related to the scarab, and there are some 100 varieties of this insect. It makes a brief appearance usually in May and June each year, hence the name "June Bug" (or sometimes "May Bug"). They are widely considered to be a pest harmful to trees and lawn.

What's that got to do with checkers, and our (more or less) monthly speed problem? Take a look at the diagram below.

So, you say, it's pretty straightforward, right? What's the point of a problem with such an "obvious" solution? Well, then--- this one could indeed "bug" you if you get it wrong. Experienced players won't have any difficulty. But the rest of us might, shall we say, get, um, bitten[1].

Solve it quickly and then let your mouse crawl over to Read More to see the solution.

Contest 62: Double Breeches

20220410-breeches.jpg

Today we won't go into the difference between breeches and britches, but we will mention that breeches are pants (or if you like, pantaloons) that cover the, um, posterior. Today that's true of most if not all pants.

What then, are double breeches? In terms of pants, we can't really say, but our Research Department did point out that the word breeches is what's known as a double plural. In old English, broc was a word which had a plural form of brec. In time the word evolved and added the usual -(e)s suffix and thus became the double plural, breeches.

If that's just a bit too complicated, fortunately in checkers double breeches has a very specific and easy to understand meaning, as you'll see in Bill Salot's 62nd World Championship Problem Composing Contest, which has double breeches as its theme. Access the contest problems here.

To get you started, here's a sample problem illustrating the contest theme. It's by grandmaster composer Ed Atkinson and was the winner of Contest 33 in June, 2017.

Warm Up

20220320-springg.jpg

It's the beginning of May, and in the Northern Hemisphere, the weather should be warming up, likely something very welcome to those of you in colder climes.

Along those lines, today we have a speed problem that is itself in the nature of a "warm up" of the mental type. It's quite easy, and may be something of a good starter to get your brain into checker mode at the start of an evening's play or study.

20220320-bwarm.jpg

An experienced player will solve it in a couple of seconds; novices may have to think a bit, but in any case, it's good fun.

Contest 61: Virile Variations

20220219-vvar.jpg

The latest entry in Bill Salot's long-running series of top-notch problem composing competitions is titled Virile Variations and features devious problems with "fake" solutions that conceal the real solution. The idea is that the solver will be misled into thinking the fake solution, which is both appealing and almost but not quite correct, is the real one.

A generous selection of six settings make up the contest entries, which you can quickly access by going to contests.checkermaven.com.

As an introduction, here's a sample problem from 1892, attributed to joint authors G. H. Slocum and C. Hefter.

There's More Than One Way To Do It

null

There's a sort of a sport played by computer nerds called Vim Golf. Now, bear with us for a moment.

Vim is a famous and venerable text editor used mostly on Unix systems but on many other systems as well. It is unique and has its faithful adherents. It's fast and is famous for being able to accomplish tasks with a minimum of keystrokes. Enter Vim golf.

In Vim golf, players solve an often challenging editing problem, using nothing more than a stock version of the Vim editor. There's more than one way to do it, but the challenge is to solve the problem--- put the ball in the hole, if you will--- with a minimum number of (key)strokes. Just like golf, only very techie. It's a lot of fun--- if that's your sort of thing.

In checkers, too, there is often more than one way to play a position. So we introduce draughts golf with a problem sent along by regular contributors Lloyd and Josh Gordon of Toronto. The position below has several ways for Black to win, but there is a best way.

Cute and Acute

Can something be both cute and acute, as in "sharp" or an "acute angle"? We think so, and we're about to show you an example.

This month's speed problem is another easy one, but it's also definitely cute. And acute. You'll see what we mean when you solve it. Beginners might have to think a bit but experienced players should solve it quickly.

Zugzwang! Problem Contest 60

20211205-zz.jpg

Zugzwang. Compulsion to move, made up of the German roots Zug, move (among other meanings) and zwang, compulsion or force. A situation in which a player has to move even though it will mean losing or incurring a major disadvantage. It's a term commonly associated with the game of chess, but it applies to checkers as well.

The 60th entry in Bill Salot's amazing ongoing series of checker problem composition contests features the theme of Zugszwang with four stellar problems illustrating this principle. Solve them, enjoy them, and by all means vote for the one you think should be the winner.

As always, the action takes place on our current contest page.

To get you started, here's an example. It's by Jim Loy and was the winning problem in Contest 34, August 2017, which featured the same theme as today's contest.

New Year's Day 2022

This column is being published on New Year's Day, 2022, and The Checker Maven wishes that the New Year will bring everyone health, happiness, and everything that you might wish for.

We don't know if or how you might have celebrated on New Year's Eve, but we know that it can often be a time of ... er ... a bit of overindulgence. If you did ... er ... overindulge a little, perhaps today you aren't ready to take on a grandmaster level checker problem. So instead, we'll take it easy on you and present a very nice, but not too difficult problem sent along by regular contributors Josh and Lloyd Gordon of Toronto.

Merry Christmas 2021

This column will appear on Christmas Day, 2021, and whatever holiday you celebrate, in whatever way you celebrate it, The Checker Maven wishes everyone the best of the season. Even in these days of extreme political correctness, we have no hesitation to say "Merry Christmas to one and all," and if you find that friendly wish offensive, that's on you.

On major holidays we like to present problems from great composers of a bygone day. Today, we feature a prize problem by the great Fausto Dalumi. The problem was first published back in 1929, going on a hundred years ago.
