We're not returning today to the famed and troubled sixties, those times of tye-dyed shirts, paisley trousers, lava lamps, and much more which we shan't explore here. Instead, we're going back a full hundred years to the days of J. D. Janvier, who named the go-as-you-please opening 11-16 24-19 8-11 "The Paisley," without the slightest foreknowledge of peaceniks, Haight-Ashbury, or bell-bottoms. (We understand that Mr. Janvier was, much more prosaically, instead making reference to a town in Scotland.)

Here's some interesting published play in the Paisley:

And so we arrive at the following position.

BLACK

WHITE
White to Play and Win

W:W32,27,23,21,19,18,K2:B26,20,16,14,12,9,6.

Without turning to your books of published play, can you, fully on your own, find the White win? Even better, can you find Black's losing move in the play above, and correct it? To help in following the play, you can click here for an on-line animation.

If the effort frays your bell-bottoms or ruffles your Paisley trousers, clicking on Read More will bring you the answers quicker than you can light your lava lamp.

Sometimes, just a little bit of difference is all it takes... and that's the subject of today's installment in our continuing series of lessons in Checker School.

Here's the first situation we'd like to have you consider:

BLACK

WHITE
White to Play and Win

W:W13,K19,21:B10,18,K32.

Forces are even, but the Black man on 10 is decidedly exposed, and we'd have to give the edge to White.

But now, take a look at this one:

WHITE

BLACK
Black to Play and Draw

B:W21,K19,9:BK32,18,10.

Not much difference, is there? It's as if White had played 13-9 in the first diagram, not at all an illogical move on the face of it, and thereby changed a win into a draw!

Checkers is indeed a subtle game, where little differences can mean a lot. Make a difference for yourself by solving these two problems, and then clicking on Read More to see the solutions, with detailed notes and a sample game.

Here are two more entries from Willie Ryan's classic Tricks Traps & Shots of the Checkerboard, as we continue our long-term project of republishing the entire book for your entertainment and edification. Let's hear Willie in his own words.

A Hole in The Dyke

The struggling tyro seems to have an unexplainable "aptitude" for walking into the following shot with his eyes wide open. I have scored with it innumerable times. To arrive at the position on the diagram, move:

11-15 22-17 15-19---A 23-16 12-19 24-15 10-19 25-22 8-11 29-25---B 11-15 27-23---C.

WHITE

BLACK
Black to Play and Win

B:W32,31,30,28,26,25,23,22,21,17:B19,15,9,7,6,5,4,3,2,1.

A---Forms the Dyke, a standard opening.
B---A very weak move, but drawable; 27-23 or 17-13 would be better.
C---Hooked! The following series of moves draws narrowly and corrects important play by F. Teschelheit: 17-13, 4-8, 21-17*, 7-10, 27-23, 8-12, 23-16, 12-19, 31-27* (the only move to draw, correcting Teschelheit, who gives 32-27 to a black win), 2-7 (if 3-8, 17-14 draws; if 9-14, 27-23 draws), 27-23, 19-24, 28-19, 15-24, 23-18, 7-11, 17-14, 10-17, 25-31, 3-7, 21-14, 24-28 (11-16, 14-10, white wins), 22-17, 11-16, 26-22, 16-19, 30-26, 7-11*, 14-10, 6-15, 13-6, 1-10, 18-14, 19-23, etc., drawn. Wm. F. Ryan.

A Six-Move Blitz

Among the most effective six-move killers is this well-known example on the Denny opening. Set up the pieces for play. Now move 10-14, 23-19, 11-16, 26-23, 9-13, 20-24---A, and we get the layout of pieces pictured here.

WHITE

BLACK
Black to Play and Win

B:W32,31,30,29,28,27,25,23,22,21,20,19:B16,14,13,12,8,7,6,5,4,3,2,1.

At A, instead of 24-20, white can get a good game by 22-17, 13-22, 25-9, 5-14, 29-25, 7-11, 25-22 (not 24-20, 14-18), 6-10, 22-18, 1-5, 18-9, 5-14, 30-25, 11-14, 25-22, 16-20, 22-17, 8-11, 17-13, 2-6, 31-26, 12-16, 19-12, 11-16, 13-9, 6-13, 26-22, 16-19, 23-16, 3-7, 22-18, 15-22, 16-11, 7-16, 24-19, 16-23, 27-9, 10-15, 9-6, 22-26, 6-2, 15-19, 32-27, 4-8*, 12-3, 26-31; resulting in a draw.

After a rather heavy-duty problem last month, this time we're heading to the somewhat lighter side with a stroke problem that should entertain without baffling. Well, not too much.

Sometimes, breaking even is the best you can do.

That is never more the case than when dealing with the United States Internal Revenue Service. And the publication date of this article, April 15, 2006, is the traditional American tax day, on which income tax returns --- and final payments --- fall due.

Keeping that theme in mind --- of doing everything you can to just break even --- take a look at today's feature problem.

WHITE

BLACK
Black to Play and Draw

B:W28,26,24,K3:B19,15,14,2.

Forces are even, but White has a king and Black is going to have to struggle just for a draw.

Ed Gilbert has set his KingsRow engine and 10 piece endgame database on the path of more deep discoveries as he continues to mine interesting problems. Here's a sample of some of the things Ed has unearthed:

• As long suspected, the alternate jump in the Single Corner (11-15 22-18 15-22 26-17) is a draw. Ed cautions us that his findings don't constitute absolute proof, but his new computer opening book shows a draw against virtually all lines of attack.
• Elbert Lowder's 13-17 defense in the Will-o-the-Wisp is a very narrow draw.
• The new book contains some interesting Switcher lines like play after 11-15 21-17 9-13 25-21 8-11 23-18 4-8.
• Ed has searched for alternate lines in the Double Cross. The book confirms that after 9-14 23-18 14-23, then 26-19 is indeed a loss. Also, after 9-14 23-18 14x23 27x18 12-16, then only 18-14 draws, and all others are almost certain losses.
• How about drawing lines in the dreaded Edinburgh? The book shows that after 9-13 22-18 6-9 18-14 xx, there are three moves to draw: 12-16, 11-15, and 1-6.
• The book makes an end of this "ash can" line: 10-15 22-17 15-19 24x15 11x18 23x14 9x18 26-23 6-9 23x14 9x18 30-26 5-9 17-14 1-5 21-17 9-13 25-21 3x22 26x17.
• And similarly, the book finishes off this GAYP line: 11-15 24-19 15x24 27x20 9-14 23-19 8-11 26-23 11-15 22-18 15x24 18x9.
• Ed looked into the 27x20 jump in the Waterloo opening: 11-15 23-18 8-11 18-14 9-18 24-19 15-24 22-8 4-11 and now if 27-20 instead of the normal 28-19, the draw is tough, but it is there.
• Perhaps most exciting of all, Ed has found five new drawing lines in the Black Hole!

Thanks to both Ed Gilbert and Brian Hinkle for providing us with input for this story.

We recently received our copy of the International Checker Hall of Fame annual, Checkers 2006, and it's something not to be missed. Once again, Charles Walker and staff have put together over 300 pages of sprawling, rambling checker play, history, and lore, including, we modestly point out, a lengthy extract from our own web site.

To get a copy, send $30 for delivery to US addresses, or $40 for international shipping, to ICHF, Box 365, Petal,MS 39465. Be sure to order right away, before a sellout takes place.

We're delighted that, in spite of the challenges in his personal life, Mr. Walker was able to produce another book that checker fans everywhere will treasure. We know Mr. Walker now faces some dark days, and our thoughts are with him. We can only hope that these days soon will yield to a brighter future for a man who has done so much for our game.

We should have known better, but we upgraded our typesetting software and the inevitable happened: we ran into some serious problems which caused an unacceptable loss in diagram quality.

We've since resolved the issues, and the diagrams look better than ever, but the loss in production time set back our scheduled electronic release of Richard Pask's Key Themes from mid-April to sometime in May.

We apologize to our readers for this delay. We can only promise that the wait will be well worth it.

As yet another teaser from our very soon to be released electronic republication of Richard Pask's Key Themes, we bring you a situation that Mr. Pask takes as far as a Black win, but leaves it to you to finish the job.

Here's a runup to the diagram:

WHITE

BLACK
Black to Play and Win

B:W32,30,24,22,21,20,19,18:B15,13,12,11,10,9,3,2.

Can you find where White went wrong, and correct the play, and then can you find the winning move for Black and finish the job?

This is a busy week, as our second feature article contains two substantial problems, related in a way that will become clear later on, and sharing a common thread of thought: at first glance, you're likely to say "So What" or even "Big Deal."

But these problems are the compositions of that noted problemist of a bygone era, Mr. Chas. Hefter, a checker force not to be taken lightly, so perhaps we should avoid hasty judgments.

Here's the first one:

WHITE

BLACK
Black to Play and Draw.

B:W28,21,K16:BK30,24,19,K15.

Well, "So What?" Black is a man up and we're just asking for a draw... oh... wait.... Black is about to lose a man and... a second one... so Black will be a man down... hmm, maybe there is something to this after all.

And now the second situation:

BLACK

WHITE
White to Play and Win

W:W21,28,K32:BK19,K25.

So, "Big Deal." White is a man up and what else should he do but win? Oh.... the king and man jammed into the double corner could make it harder... hmm, maybe it's not as easy as it first looked.

Try out the problems but if you are stumped, so what. Clicking on Read More to see the solutions is no big deal.

Some of our problems, we admit, can be on the tough side, especially for the average player. But today, we'll give you a checker problem that is easier than you might think:

To open the month, we've chosen a speed problem that may take you a bit longer than some of the others we've run in the past. In fact, we were right on the edge in our decision as to whether or not this is a true speed problem; but the solution is simple and snappy... once you see it.

You know the drill. Click below to show the problem and start the clock. We've allowed you three minutes on this one, but what's your hurry?
