Willie Ryan's classic Tricks Traps & Shots of the Checkerboard, presented here in a new electronic edition, is up to the sixth installment. Here's what Willie has to say on page 16 of the book.

'The issue is clearly drawn in Example 11. The white king on square 22 has a strangle hold on black's pieces on squares 13 and 29, but the black king on square 1 is threatening to go 1-5 next, followed in order by 5-9 and 9-14, and then releasing his impounded pieces by squeezing 14-17, thus driving the white king on square 22 from its potent position. The proposition, therefore, is for white to maintain control of square 22 by preventing the black king on square 1 from effectively advancing up to square 14. This is artistically accomplished by the "shift and stem" principle. It's easy to master these tactical "killers" with step-by-step study.
And now we come to one of the most common of all tactical tricks--- the ever useful pinch play. As the term suggests, a pinch is a move that puts pressure on an opposing piece so that it cannot avoid capture, whereas in a "squeeze" play the threatened piece can avoid capture by moving to an adjoining square. All checker strategy is premised on force, carried out by tactical devices, and the pinch and squeeze are two of the most frequently employed weapons of the adroit tactician. Example 12 is a sparkling illustration of a delayed pinch, wherein white eventually forces black to lose a piece (and the game) by a perfectly timed pincer.'

'Example 9 is such a simple win that white can polish off black in just three of his own moves; and yet this "pitch-a-piece and block" coup has been muffed even by better class players. At first glance, white appears to have a win by playing 32-28, but black counters with 14-17, 22-13, 7-10, 13-9, 10-14, 19-15, 16-19, 23-16, 12-19, 9-6, 14-18, and steals the piece on square 27 to draw. One of the most fascinating factors in scientific checker play is the element of surpirse. Example 9 features a position that, by ordinary processes of play, can only be drawn; but a jolting pitch (sacrifice) at the right moment changes the complexion of the situation decisively.
White doesn't have the move or opposition to win in Example 10, and there appears to be no way to effect an exchange to get it. This poses the question, "Is there any way white can alter the move in Example 10 without actually making an exchange?" The answer is yes---by the "pitch and grip" idea. The pitch and grip is precisely what the term implies. You pitch a piece and then apply a grip that forces black to lose not only a piece but the move and the game as well. Some of the ideas we have discussed in this chapter occur more often than others in play, but all are equally important to mastery of the game. Usage of all sorts of ideas is what makes checkers a fascinating study and a challenge to one's ingenuity.'

Our Masked Man problem series draws to a close with this month's article. We hope you've enjoyed it. Perhaps we can run another similar series sometime in the future.

If you can identify the problemist in the photo below, you're doing really well at this sort of thing.

Now, here's his problem. Our guest problemist gives the terms as White to Play and Win. What do you think?
White is a man up and by rights ought to win, but can you do it? Can it in fact be done at all?

Check your solution by clicking on Read More. Intended to be of "medium" difficulty, this one packs a surprise. Even if you solve it easily, though, by all means read the commentary which accompanies the solution.

We continue again this month with our "summer light" series of easier-than-usual stroke problems with this offering for June, which is, as you will see if you figure it out, a bit mis-labeled. And be forewarned, after this series concludes it's back to the hard ones!

A recent addition to the library in our Santa Fe office is an item we've sought for quite some while: W.T. Call's Midget Problems, published in 1913. We think the following quotation from the preface to this little booklet is revealing:

'Are not these little problems easy?

'Yes, when you are looking at the solutions.'

Over the coming months we'll be featuring some selections from this work, which features nothing but problems with two pieces per side, hence the title, Midget Problems. But as the preface warns, these are small only in size, not in challenge.

We'd like to start out with an offering that you might consider trite; and frankly, we'd have to agree, yet there is a method to our madness. It is a setting of First Position, credited to Dr. T. J. Brown of Limerick, who put this forth around the year 1870.

There's nothing new or different here, and yet we strongly urge you to try this out. Play it against your computer, or practice it with a strong opponent. How well do you really know First Position? Sometimes a thorough review of a familiar concept is a well-worthwhile exercise, as so often we find our knowledge isn't quite as solid as we would wish to think.

And when you've worked through this setting (you can click here for an animation of Dr. Brown's trunk solution), answer this trivia question, also credited to Dr. T. J. Brown. What is the earliest published example of First Position? Can you name the author and year? If you can, you really know your draughts history.

But before you're done, tell us, if you can, what White's last move might have been, and then draw a conclusion from your answer. (Thanks go to Brian Hinkle for this one.)

As a special Saturday extra for our readers, we offer this Tommie Wiswell Prize Problem, which is actually somewhat easier than most Wiswell offerings, but certainly no less elegant.

Forces are even but, to say the least, White does not have a lot of options. Can you save the day for the White team? Give it your best and then click Read More for the solution.

As this article goes to press, the battle has been joined to decide who is Number One in the world of British/American checkers and draughts. Alex Moiseyev of the United States is defending his world championship against long-time rival Ron "Suki" King of Barbados. Alex is providing his own colorful daily commentary on the Checker Solutions BBS, and it's not to be missed.

After today's play (27 May 2005) Alex is leading Ron 5 to 2 with 13 draws. This is spirited, fighting checkers - how often do we see 7 out of 20 grandmaster games end in a victory? But no matter who finally emerges from this battle as the present-day Number One, we're seeing checkers at its very best.

(Editor's note, 01 June 2005: Alex wins the match with a score of 8 wins, 3 losses, and 25 draws!)

Right now, though, we want to take you back to an earlier contest for the claim to the title of Number One, a match held in the U.K. in 1958 between the American great Marion Tinsley and the British grandmaster Derek Oldbury. Tinsley walked out the undisputed world champion with nine wins, one loss, and 24 draws. Despite the seemingly uneven score, the match was hotly contested and produced some very fine play.

But the match also produced a few unexpected and memorable errors! Today we'll ask you to take on the persona first of Marion Tinsley and next of Derek Oldbury, as you try to find the move to save the game, in positions unexpectedly lost by these stars of yesterday.

Here's a position from the very first game of the match:

Tinsley played 5-9? and lost at once to 7-16 12-19 27-24 White (Oldbury) wins. It was a shocking defeat, and The Times of London headlined: 'Sensational' Opening Win In World Draughts Contest. Can you find the line of play that would have secured the draw for Marion Tinsley?

Now let's leap ahead to Game Seven. Here's the situation:

Oldbury, to everyone's surprise, played 4-8 and lost to 19-16 12-19 24-15 10-19 23-16 8-11 16-7 2-11 26-23 11-16 28-24 White (Tinsley) wins. What would have been the course of action for Oldbury to get the draw?

The May installment of our ongoing "Masked Man" series will give our readers a bit of a reprieve, and a chance to perhaps actually guess the identity of our featured problemist.

As in previous months, your task is to identify the problem composer pictured above, and solve his checker problem, given below.
Black is a man up, but about to lose (at least) one of the members of his armed forces. We'd rate this problem as at least medium in difficulty.
