In 1892, John T. Denvir was working at a lucrative $2,000 per year job. During the lunch hour, he would go to his checker club to play a few games in the space of the one hour lunch period. One day, he played a rather brilliant game against Lucius S. Head, which however caused him to return to work an hour late. He fully expected to be fired, and considered himself very lucky indeed to have gotten off instead with a stern scolding.

Here's the runup to the critical position:

11-16 23-18 10-14 18-15 16-19 22-17 7-10 24-20 9-13 26-22 5-9 30-26 8-11 15x8 4x11 27-23 2-7 23x16 12x19 32-27 11-15 20-16

If you can solve it, you certainly have excellent visualization skills. Check your solution against our animation, which includes the whole game.

A brilliancy indeed, but is it worth your job?

Continuing our monthly "Masked Man" series, this month's offering is perhaps the most difficult to date. Can you identify the problemist pictured above (posing with his daughter), and then solve the problem below?
Forces are even, but White's freedom of movement seems limited... can you pull off the draw? No less than four "star" moves will be necessary.

A little while back we lamented the presence of computer-using cheaters on the major online play sites. We recently came across an article published over 80 years back in the Morris-Systems Checkerist magazine that highlights a similar problem, and how one cheater got what he had coming. We've reprinted the article below.

The desire to win in any form of competitive sport is a very human one. Facing a man who is a degree stronger or more skillful, and submitting to defeat after defeat is a test of character, temper, fortitude--or, reduced to one word, a test of sportsmanship. Occasionally we encounter an individual for whom the hunger of victory is so intense that while he would probably shrink from attempting an unfair or unethical move in other walks of life, he has but meager scruples as to the management of his game, and in order to gain the upper hand resorts to illegitimate tactics. The number of such is of course infinitely small compared with those who would rather be riddled to pieces than surrender their principles of good sportsmanship; but even the insignificant number of sly-hand movers is to be regretted.

Not always, however, is it profitable for the sly-hander to make his moves unseen, and the man who thinks he is "getting away with it" will find now and then that he has dug a pit for himself too deep for escape.

We happened into a rather amusing demonstration of this not long ago while watching a player of good repute in a park exhibition where he was handling a number of boards simultaneously. As the exhibition player went from board to board we noticed that one of his opponents near us advanced a piece as if to test the position, then glanced up to see if he had been observed. When the exhibition player appeared at this board again the opponent made his regular move, but the piece he had advanced a minute before remained where he had placed it. The exhibitionist was plainly surprised. Evidently he had remembered the earlier position. We saw him eye his man with a keen glance, but said nothing, made his move and then went on to the next board.

Later, in the end game, the position on the board was as shown (below).

The exhibition player had the white side. As he passed down the aisle to other boards, the "double mover," seeing himself pursued by the white king, made another illegitimate move, going from 5 to 9, with the thought of preventing white from playing 8-11 (which would then lose to 20-16 --Ed.). He scratched his head as if wondering whether his conscience would stand for it. When the checker performer returned to the board he caught the situation at a glance. He raised himself to a straight posture and looked squarely at his man, puzzled for words, but unwilling to embarrass the other while the crowd stood by. Nevertheless, his steady, searching look told the "double mover" he was discovered. Here is a picture of the board after the illegitimate move:
Studying the situation carefully the exhibition player smiled inwardly as he became aware that his opponent had unwittingly entangled himself in the coils of a binding trap.

Had the "double mover" been content with his first illegal move he might have gained a draw, but when he repeated his offense, he apparently aroused the wrath of the checker g-ds and brought himself to swift and sorry doom.

We continue our electronic republication of Willie Ryan's classic Tricks Traps & Shots of the Checkerboard with this, our third installment. But let's let Willie speak for himself.
'Like all other tactical schemes, the delayed smother play can occur on other parts of the board with varying arrangements of the pieces. Example 5 shows a natural-looking ending in which white can neatly bottle up black's pieces in just five moves, by a delayed double corner "jam." Examples 4 (published in a previous article --Ed.) and 5 illustrate but two types of the smother play; there are several other varieties including blocks, freezes, lock-ups, and the smother pinch. Indeed, checker ideas are as numerous as words, and each one has a meaning of its own, and a special adaptability in the course of scientific play.
The situation on the right (actually above --Ed.) is still another member of the smother family. To press home the win in Example 6, white must actually coordinate the germs of two different tactical ideas, employing the smother as the winning device and using the seesaw shift (as in Example 11) (to be published by July 2005 --Ed.) as the timing element by which the smother is executed. When two or more tactical ideas are woven into a procedure of force, we call it a "combination." positions are always popping up in play where it is necessary to grapple with a dozen or more ideas in order to force a scientific win, or obtain a delicate draw!'

At the suggestion of our readers, instead of publishing everything on the weekend, we'll be trying out the idea of dividing up our new articles between Wednesday and Saturday. Although we'll likely feature a problem on most Wednesdays, "anything can happen" so stay tuned, and be sure to let us know what you think of our revised publication schedule.

Now, on to this week's Wednesday problem. Originally published over 80 years ago, it was billed as a beginner's problem. And it's surely a case of "anything can happen" in that there were flaws in the original setting, clever though it was, and so we've made a few changes.

We start with this position, as originally published:

The published solution gave 14-17 to a draw, and that is correct; however, computer analysis shows that both 14-10 and 14-9 will also draw. Too many solutions spoil the problem.

But in the diagram above, what is the move that comes to mind at once, and that a beginner in particular would likely choose? It's 14-18, attacking two Black men at once. Yet this move loses! Here's the position, and the challenge for you:

Did you get it? Click on Read More for the solution, and decide for yourself, though this is a situation a beginner might encounter, if this is truly a beginner's problem.

By the way, you get bonus points if you can recall where the idea of Wednesday being "Anything Can Happen Day" originally came from.
