May Stroke

20140409-maystroke.jpeg

After so many years of publication, we're out of "stroke" puns and find it necessary to do repeats. But the photo above is definitely a harbinger of spring and summer; rowing crews out on the water, enjoying outdoor activity, perhaps after a long winter.

Today's problem is relatively easy and is set with only four pieces per side; it's a little more practical than the more complex, artificial stroke problems.

Horse-Radish

20140409-horseradish.jpeg

Horseradish, of course, is a well known condiment, with a sharp taste and sinus-clearing effect. It's often enjoyed with prime rib of beef, on hot dogs, and in numerous other ways. It's not to everyone's taste; you either love it or you don't.

Horse-radish, in checkers (note the hyphenation) is an older term not much heard today that refers to moves that are sharp, like horseradish, but not to everyone's taste, because they are usually unsound or at least questionable in theory. They're all about over the board play; a horse-radish move, even if inferior, may be hard to refute on the spot if you're not familiar with the line.

You won't be surprised to hear that Willie Ryan was a fan of horse-radish, and the following problem comes from a horse-radish line in one of his earliest books.

A Bristol Broadside

20140402-broadside.jpeg
Stephen Dowle CC BY 2.0

The word "broadside" carries various meanings, and perhaps the one that comes to mind at first is the "broadside" fired by the cannons on warships of a bygone day. Cannons were arranged on the sides of the ship, and having all of them fire a more or less simultaneous volley made for a powerful attack.

But there's another meaning. British photographer Stephen Dowle notes that advertising on the side and front of a bus, as illustrated above, is often called a "broadside"; hence, the photo is titled "Bristol Broadside."

Our presentation of Willie Ryan's Tricks Traps & Shots of the Checkerboard continues with an exposition on the 11-16 Bristol opening, presented in four parts due to its length. To say that this first part is explosive and spectacular is almost an understatement. Certainly Willie was thinking of cannons and not buses.

Here's Willie's run-up and notes. Additional variations will appear in future columns.

20-16---F,2 18-25 19-16 5-14
14-18---G,3 29-22 17-22 6-10

A---"The text was a long-standing favorite with that renowned celebrity of the draughts world, James Wyllie. It was also popular with many other stars of the Andersonian firmament. Although it has gained only negligible favor with the modern exponents of the go-as-you-please school, one is certain to regard the line with increasing respect as its ramifications are mastered.

B---In a title game between two world's champions, Richard Jordan and James Ferrie, the former attempted 27-23 here. The game proceeded 8-12, 23-16, 12-19, 18-15, 4-8, 25-22, 9-13, 32-27, 5-9, 29-25---C, 7-11, 27-24,11-18, 24-15---D, 2-7, 20-16, 7-11, 16-7, 3-19, 22-15, 14-18, 26-23, 18-27, 31-24, 9-14, 24-20, 14-18, 20-16, 8-12, 16-11, 19-23, 11-7, 23-27, 7-3 (30-26, 27-31, 26-22 should develop a draw), 27-31, 28-24, 31-27, 24-20, 18-23, 15-11, 6-10, 3-7, 12-16, 7-14, 23-26, 30-23, 27-9, 11-7, 16-19, 7-3, 9-14, 3-7, 14-18, and Ferrie won. Considering the usually high caliber of Mr. Jordan's play, this one stands out on the record as one of his worst examples. Time and again he displayed a remarkably dull grasp of the involved positional structures.

C---15-11, 8-15, 27-23, 1-5, 23-16, 14-17, 21-14, 9-25, 29-22, 7-11, 16-7, 2-11, 30-25, 6-10, 25-21, 5-9, 22-17, etc. would be a much easier way for white to play for the draw. Wm. F. Ryan.

D---This seems to be about the spot where the Great Jordan fell into error. A draw after 24-15 is difficult to reach. The alternative jump gains the draw easily with: 22-15, 3-7*, 20-16, 7-11, 16-7, 2-18, 24-15, 6-10*, 15-6, 1-10, 28-24*, 8-11 (10-15, 31-27, 8-11, 26-23), 24-19*, 18-22, 25-18, 14-23, 19-16, etc. Wm. F. Ryan.

E---The line of play initiated at A is usually associated with this follow-up, although black can safely adopt other moves, as depicted in Variation 1. The student should bear in mind that the strategical advantage in adopting a dormant line of play, such as the one begun at A, is twofold: first, it may throw the adversary off lines of play he is most likely to know; second, it gains the initiative and efficiency that go with employing a well-prepared plan of attack. It has been proved time and again that a player who takes a weak line of play and knows it thoroughly will win more games than the one who adopts a standard procedure of play without knowing how to carry it through.

F---To the player handling the white pieces, this is an important waiting move, as it simplifies the formational structure by thwarting any attempt by black to secure tenable complications. See Variation 2 for 25-22 here.

G---Just about all that black has left. For play on 9-13, see Variation 3. Alfred Jordan tried 2-7 here in a title match duel with Melvin Pomeroy and finished on the rocks by 16-12, 14-18, 21-17*, 9-14, 17-13, 5-9, 27-24, 7-11, 26-22, 19-23, 31-27, 10-19, 24-15, 14-17, 27-24, 17-26, 15-10, 6-15, 13-6, 1-10, 32-27, 23-32, 30-7, 3-10, 12-3, 11-16, 24-20, 16-19, 3-7, 10-14, 25-22, 14-18, 7-11, 18-25, 29-22, 19-23, 11-27, 32-23, 28-24, 23-26, 22-18, 26-23, 18-14, 23-18, 14-10, 4-8, 10-7, 18-15, 7-3, 8-12, 3-8, 15-18, 24-19; white wins.

H---White must accept the clearance or drift into a ragged formation. If 27-24 is played, then black wins with:" (See solution---Ed.)

Is It Spring Yet?

20140310-sp0414.jpeg

Technically, it's already spring in the Northern Hemisphere, as the vernal equinox always arrives in March. Whether or not it's warmed up in your location is something else, and since these columns are written some weeks in advance, we really can't say. Hopefully, the long winter is coming to an end for most North Americans. (If you're in the Southern Hemisphere, we realize you're moving into winter, and we can only hope on your behalf that it will be a mild one.)

To herald the arrival of spring, we have an easy speed problem that will entertain without baffling.

A Little Mischief

20140305-mischief.jpeg

We owe today's problem to a certain L. L. Granger, who published it as Prize Problem No. 4 in The Canadian Checker Player nearly a century ago. He called the problem "A Little Mischief" but it turned out to be rather a lot of mischief.

Uncle Ben's Porch: The Checker Maven

20060811-porch.jpg

It goes without saying that Uncle Ben and his protegé, Tommy Wagner, were avid readers of the weekly internet checker column, The Checker Maven. So when Uncle Ben saw the recent Checker Maven column called Hobson's Choice, he realized that it related to a game that Tommy played recently in a match in his middle school checker league. Tommy missed a win in that contest and had been kicking himself about it ever since.

Tommy was on Uncle Ben's front porch for his weekly checker lesson from the retired master. Uncle Ben was proud of Tommy's achievements and knew that Tommy had the potential to go on to great things, perhaps even making it one day to a team in the National Checker League.

"Tommy," Uncle Ben said, "I think it's time for you to get past that missed win against Tallahassee a couple of weeks ago."

"I know, Uncle Ben," Tommy said, "but I feel like I let my teammates down. I should have won..."

"The best way to make it up is to study that weakness in your game and eliminate it. The best players make strengths out of weaknesses, and that goes for many things in life. If you have a weak point, work so hard at it that it becomes a strong point instead."

"How can I do that, Uncle Ben?" Tommy asked. "It just seemed to have gotten away from me..."

Uncle Ben smiled. "I've put together a series of positions," he said. "If you work through them, I guarantee that you'll never miss a win on this theme again. It might take a little while, so if you're willing, I'll let your mother know that you'll be home later than usual. I can make us some lunch and we can study until, say, mid-afternoon. What do you say?"

The one thing that Tommy liked as much as Uncle Ben's checker instruction was his lunches. And, of course, his homemade lemonade. "Sure thing, Uncle Ben, if you're willing to spend the time, I'm ready!"

20070917-lemonade.jpg

Uncle Ben knew Tommy well. "Good, then, take a look at this position while I get us some lemonade." He winked at Tommy and went inside to the kitchen.

Here's the situation that faced Tommy, and it looked a lot like that Wednesday afternoon in Tallahassee. Tommy gave an involuntary shudder, but then he shook it off and got to work.

Mitchell's Miracle

Albert Einstein once said, "There are only two ways to live your life. One is as though nothing is a miracle The other is as though everything is a miracle."

But a miracle in checkers? Well, this month we present Mitchell's Miracle, the second part of The Champion's Choice, which we began in last month's Tricks Traps & Shots of the Checkerboard installment. Please see there for the run-up to Variation 2, which begins from the diagram just below. Willie Ryan is here to tell us more. It can be a little confusing, so if you get lost, just go down to the bottom of this article to see the problem diagram.

14-18 19-26 5-9 3-12

A---The best that white can hope for after this move is a problematical draw---1. If white attempts 31-26 here, then 14-18, 23-14, 9-25, 29-22, 11-16, 24-20, 16-19 will leave black with a winning game. Another plausible try at A is 22-17. Black's strongest reply to this move is 14-18, 23-14, 9-18, which leaves white confronted with the critical situation shown on the diagram. I published play on this position a few years ago, claiming a black win against any defense adopted by white, but a problematical draw was found as follows. (See solution---Ed.)

C---Black can prolong the game by forcing white into a bridge ending like this: 14-17, 22-18, 17-22, 18-14, 22-26, 14-9, 6-10, 9-6, 10-14, 6-2, 14-17, 13-9, 17-21 (to stop the pitch by 9-6 next), 19-15, 26-31, 15-10, 31-26, 2-7, 26-22, 9-6, 22-18, and white having the move, can draw the ending."

1---The computer finds this move to be about as good as 23-18---Ed.

A---6-10 is much better here.

B---Turns a relatively small disadvantage into a probable loss. 6-9 would have minimized the damage.

C---A real lesson in the need to keep your head while you're ahead. Instead of playing 15-10 to go on to a probable win, White will now lose!
