Two Easy Pieces: Sixth Edition

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.


White to Play and Win
'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.

White to Play and Win
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.'

Fifth Reprise: Two Easy Pieces

Here is the fifth installment of our continuing series from Willie Ryan's classic Tricks Traps & Shots of the Checkerboard. As always, we're here to listen to the man himself; click on Read More to check your solutions.


White to Play and Win
'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 to Play and Win
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.'

A Great Shot, But Can You Win The Ending?

(We are taking a short break and so this really is our last Wednesday column until September. Saturday columns will of course continue without interruption.)

On this "Anything Can Happen" Wednesday, we bring you a game played by guest author Ingo Zachos in a recent matchup on the It's Your Turn on-line game site. Capitalizing on an error by his opponent, Ingo finds a thrilling shot--- and then still has to demonstrate the win in the endgame! We've interspersed Ingo's own interesting comments and analysis with our own, which are due to running the world-class King's Row program at 15 minutes per move.

Ingo Zachos - Raymond Faircloth
It's Your Turn January 2005
with commentary by Ingo Zachos

1.11-15 23-18
2.8-11 27-23
3.4-8 23-19
4.10-14 19x10
5.14x23 26x19

I know 6.7x14 is the fashion, but I was inspired by Game 7 of the GAYP World Championship of 1956, Wiswell- Fraser, after reading International Checkers and Draughts.

7.7x14 24-19
8.11-16 31-26

Here Fraser played 8...19-15 and after 9.16-19 22-17 10.14-18 25-22 11.18x25 29x22 12.12-16 22-18 13.16-20 17-14 14.9-13 14-10 15.19-23 18-14 16.2-7 31-26 17.7-11 26x19 18.11x18 he played 19-16 and lost, thus: (18...32-27 19.18-22 19-16 20.8-12 16-11 21.12-16 28-24 22.22-25 21-17 23.13x22 30x21 24.22-26 21-17 25.26-31 10-7 26.3x10 14x7 27.1-6 7-3 28.6-10 3-7 29.10-15 7-10 30.16-19 27-23 31.19x26 10x19 32.20x27 19-23 is given by Dr. Fraser as drawn.) 19.18-23 16-12 20.8-11 10-7 21.3x17 21x14 22.1-6 12-8 23.13-17 8-3 24.17-21 3-8 25.23-27 8x15 26.6-9 32x23 27.9x27 28-24 28.27-31 24-19 29.20-24 15-18 30.24-28 19-16 31.28-32 18-22 32.32-27 16-12 33.5-9 22-17 34.27-23 12-8 35.23-19 8-3 36.19-15 3-7 37.31-27 7-2 38.15-10 17-22 39.27-23

9.16x23 26x19

10.9-13 trying to avoid the rapid advance of White's single corner side, is better, but I underestimated the power of the man on 15. (King's Row thinks any of 2-6, 1-6, 2-7, 8-11, 9-13, or 3-7 are about equal. --Ed.)

11.11x18 22x15

I also calculated 12.2-7 28-24! but there seemed to be equality with less chances of a tactical surprise. (The idea was the trick 12...15-10? 13.14-17 21x14 14.9x18 to a neat win.) 12.3-8?! would be a minor variation because of 15-10 and the piece on 10 is very disturbing. (In fact, Kings's Row agrees that 3-8 is weak. --Ed.)


Sometimes masters say they calculate 50 moves ahead. Well, here I already saw the final position of this game in my mind very clearly and knew it was won.

13.1-6 as indicated by the programs, might be better, but during the game I evaluated it as drawn.

(Editor's note: King's Row thinks 12. ... 15-11 is inferior, though not an outright loss, and prefers 30-26 or 25-22. But King's Row disagrees with our author over 13.14-17, rating the resulting position as a draw. As our author points out 1-6 is preferred but the game is still far from a win.)

14.9x18 30-26?

Believe it or not, this is already the fatal mistake.

It's Not Just About Winning: A Checker Maven Editorial

Controversy rages today, as it did nearly 80 years ago, over the selection of the US team in the upcoming 100th Anniversary US-Great Britain match, to be held in Las Vegas in September. One look at the postings on the Checker Solutions BBS tells the story... and that story has many angles and viewpoints.

In brief, the controversy is over the exclusion of venerable grandmaster Leo Levitt from the US team. As near as we can determine from the BBS postings, Mr. Levitt was originally asked to play, but a vote by a team selection group determined that Mr. Levitt should sit out in favor of a possibly younger, more recently active player.

This type of discussion is nothing new. Let's turn back to a publication we've quoted before, The Morris-Systems Checkerist for September-October 1926. At that time in checker history, the US team was being chosen for the 2nd International Match between the US and Great Britain.

The lead story in the Checkerist was titled "International Team Will Select 11th and 12th Men at Once" and bore the telling subtitle "Matches Called Off Due to Lack of Harmony Amongst Players." An article titled "An Old Timer Comments" by John H. Finn of the Lynn Item stated:

"Yes, the hand of time bears heavily upon all of us and none can escape its fierce grip. The American players are growing old, too, and sooner or later all of the great ones will be too old to get a grip on the game and hold that grip for many moves ... it cannot be said that an old man is one who would be preferred for team play. This applies generally to all who have reached that stage in life when they prefer rest rather than excitement...."

With all due respect, Mr. Finn, we think you were somewhere out in left field with your comments, and as the saying goes, you confused "retired" with "tired." And you tragically underestimated the immeasurable value of the older generation.

The Checker Maven editorial staff cannot support Mr. Finn's 1926 position vis-a-vis the 2nd International Match and likewise cannot support the 2005 decision to omit Mr. Levitt from the US team being assembled for the 100th Anniversary Match.

We base this position not on our knowledge of checkers, which our readers know is limited at best, nor on our familiarity with the players and their abilities, which is likewise circumscribed. Nor do we intend our position to be a criticism of the American Checker Federation or the team selection officials, who we believe to be acting according to what they see as their mandate. They are in an unfortunate no-win situation and will face criticism regardless of their final decision.

We base our position instead on what we learned from our father, of blessed memory, who taught us checkers many decades ago.

We learned that there are things more important than winning. While we learned to play to win, we learned to lose with sportsmanship and grace. We learned that checkers is all about honor, respect, perseverance, humility, hard work, ethics, and ultimately, wisdom. Over time, we've come to see these attributes in the checker community at large and it's cemented our relationship to the Game of Kings.

In the light of these precious principles, which make checkers much more than just a game, and all about much more than just winning, we ask if the exclusion of Mr. Levitt from the US team upholds and serves these principles; and we fear that it in fact does not. We ask whether disappointing an aging grandmaster who has contributed immeasurably to our game, and likely has much more still to offer, is in our best interests. (Mr. Levitt's record of 32 wins with only 1 loss and 45 draws in previous International matches speaks for itself.)

Grandmaster Leo Levitt

Likewise, we admire and applaud the offer of a young and highly skilled player, Clayton Nash, to stand aside to make room for Mr. Levitt. In making this offer, Mr. Nash models behavior and attributes that are a worthy example for us all, and acts in the true spirit of our game.

We do not know how this will all turn out in the end. But we will close with this question: if, in pursuing the goal of victory, we sacrifice our principles, what do we really win?

Did Marvin Blow The Game?

The Detroit Doublejumpers, lead by their intrepid team captain, Marvin J. Mavin, were at the St. Louis Sports Drome for a contest with the St. Louis Switchers. Marvin was engaged in a First Board match with the Switchers captain, that intrepid French National named Jean Luc Louis Claude Simon Tournevise, otherwise known as "Louie Screwdriver."

"You 'ave made a vehree bad ligne of play," remarked Louie with a curling of the lip and a bit of a sneer. "Maintenant, I will 'ave to show you zee ehror of zis ligne by giving you zee beating!"

Here is how the game had played out so far. Marvin, who was commanding the Red pieces, and Louie, in charge of the White forces, had indulged themselves in this line of the Single Corner:

1. 11-15 22-18
2. 15x22 25x18
3. 12-16 29-25
4. 10-14 24-19
5. 16-20 25-22
6. 7-10 28-24
7. 8-12 32-28
8. 4-8 30-25
9. 3-7 18-15
10. 9-13 19-16
11. 12x19 23x16
12. 10x19 24x15
13. 8-12 15-11
14. 12x19 11-8
15. 7-10 8-3
16. 2-7

This resulted in the following position, with White to play:

RED (Marvin)
WHITE (Louie)
White to Play - Can White Win?
Marvin seemed only slight irritated by Louie's taunts. He simply replied, in his most politically incorrect manner, "Well there, Monsieur Frenchy, you ain't a gonna pull this one off nohow!" Louie looked puzzled. "Ah, I do not un-derstand zis American way of fun-ee talk-ing," he replied, "but I un-derstand 'ow to make of zis game a vic-toree!"

What do you think? Try your luck and skill on these questions:

1. Can White (Louie) find a win in this position? What might it be?

2. Does Red have something up his sleeve, or did Marvin perhaps have a little too much pre-game beer?

3. What do you think of this line of the Single Corner? Did Red play well? Did White?

Watch The Checker Maven for the conclusion of this story, and the answers to all these questions and much more, in a few weeks' time.

It's Easy When You Know How

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.


Black to Play and Win
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 usual, click on Read More for the answers.
