Take a good look at the image below. It's an artist's conception of a serious checker game in a rural grocery store. Nice drawing, but the artist was clearly not a checker player.

However, the game these two are playing in fact could be one of two (or maybe even more, but we know of two) little-known checker variants, one of them quite old and the other quite modern. The game also looks a lot like (but isn't quite) several other unusual variants.

Do you know what variants would be an exact match? Can you name a few also-rans that don't quite make it?

The title of this problem is a saying of Tom Wiswell's, and when you find (or see) the solution, you'll understand the wisdom of it. The position arose in a handicap game that Mr. Wiswell played something like 50 years ago.

You might find this one a little difficult unless you're used to solving a certain type of problem (but if I told you what type I might be giving away too much). Good luck! When you've solved it, click here for an animated solution.

Carol Joy Cole, a retired librarian in Flint, Michigan, is known nationally and internationally as a backgammon club and tournament organizer, equipment and book supplier, and veteran backgammon player. What is not as well known is that in recent years, Carol has been a friend to the checker playing community, helping out with the difficult task of obtaining true "regulation" red and white checkers. Carol, through her Backgammon Boutique has up to now been providing us with solid color red and white checkers from Denmark, and "swirly" red and white checkers from Crisloid.

These have been fine items, though the "swirly" checkers are not strictly regulation, and the Danish checkers are a bit on the thin side. Now, Carol has improved her offerings by obtaining Roger Blaine's special order stock of genuine solid color Crisloid red and whites, in both 1.25 and 1.50 inch diameter sizes.

I splurged on both of these sets, and they are wonderful. The color and manufacture is uniform and the "feel" of the pieces is great. These are true regulation checkers, and an excellent value at $20 for the small and $30 for the large, plus $4 for shipping. Get them while they last!

Carol has gone out of her way to serve checker players, even though it's a small market and not likely to bring her much return. Carol is always helpful and courteous and ships promptly with no fuss or ado. Carol, on behalf of checker players everywhere, please accept our thanks!

You can reach Carol through her web site, as linked above, or by email at cjc@tir.com.

On January 10, Charles Walker announced the forthcoming closing of the International Checker Hall of Fame in Petal, Mississippi, as well as his resignation as President of the World Checkers Draughts Federation and other posts which he had held. The announcement can be found on the American Checker Federation website.

On January 11, Mississippi newspapers published this article about Walker's January 7 arrest and indictment on Federal money laundering charges. The charges are tied to a series of companies operated by Walker, including the International Checkers Hall of Fame.

Prominent checker personalities and officials have been quick to point out the outstanding contributions made over a period of decades by Mr. Walker to the game of checkers. He has been a tireless promoter and organizer and has worked hard on behalf of the checker-playing community.

The charges against Mr. Walker are serious indeed. But let's not forget that in America, a man is innocent until proven guilty. Mr. Walker deserves fair consideration and a fair trial. And no matter the outcome, his record of service to the checker world will always stand.

From an old Willie Ryan book, here is the first feature problem for January, Coffee and Cake. Willie had the following to say about it:

"This problem has been dubbed by experts the champion 'coffee and cake' problem. This means that you can set this problem up for your friends and bet them coffee and cake that they cannot win it."

I bet Brian Hinkle coffee and cake, and not surprisingly, I now owe him! But can you win it? Give it a good try and then treat yourself to coffee and cake no matter the outcome.

You can view an animated solution here. Did you win coffee and cake?

In many parts of the Northern Hemisphere, January is a cold month, and so a warmup might be just the thing! Here is a simple problem to get you started with this month's Checker Maven challenges--- but beware, they all won't be this easy!

Brian Hinkle sent us this run-up from the Double Corner opening:

9-14	23-18
14x23	27x18
12-16	22-17---A
16-19	24x15
10x19	31-27?---B

A---A defense from Teschelheit's Master Play of the Checkerboard, unfortunately unsound.

B---Loses at once, although White is probably already lost. One alternative line of play from the KingsRow computer engine is this: 26-23 19x26 30x23 11-15 18x11 8x15 32-27 5-9 31-26 4-8 25-22 8-11 23-18 15-19 27-23 11-16 17-13 7-11 29-25 1-5 22-17 3-8 17-14 8-12 25-22 11-15 18x11 9x27 Black Wins.

After 31-27, the following position arises:

A couple of interesting items have recently appeared on the CSi BBS (see link at left).

First, Martin Fierz has released a new version of CheckerBoard (click on the link to download). This release fixes and adds a few things, but mostly allows use of Hans L'Hoest's OCA database, a very large collection of checker games.

Checkerboard is surely one of the premiere checker interfaces available. We all owe Martin, big time, for developing, maintaining, and enhancing this fine software.

Second, Draughts Razoo, which to my knowledge is the only full-fledged checker print magazine (there are several newsletters), is discontinuing publication. The editor, Nick McBride, simply doesn't have the time any longer for such a major undertaking. 'Tis a pity. The days of my grandfather were filled with checker magazines and newspaper columns. Is there a single one left? Comment here if you know of any, for the benefit of us all.

Al Lyman, noted commentator, correspondence player, and checker educator, has proposed a monthly on-line magazine. This would be a "complete" magazine going well beyond an episodical blog such as The Checker Maven. Al is certainly well-qualified to do this and I wish him success. It's a lot of work; don't I know it! Keeping up The Checker Maven is effort enough, but a full monthly magazine will require concerted effort and a lot of help. I hope it works out and enriches the checker world thereby.

On the checker program review page, you'll find our review of the very unusual checker playing program Blondie24. One of the reasons that the program is unusual is that it is one of a very few "neural net" checker programs, a type of program that "teaches itself" to play. This approach has produced world-class backgammon programs but hasn't done well with non-probabalistic games.

It doesn't come close to world-class results in Blondie24 either, despite the authors claim of expert-level play (although it doesn't do that badly either). However, though neural network programming is interesting and different, that isn't at all what makes this program unique. I won't spoil it for you here; just use as a clue the fact that the game is subtitled "Checkers With An Attitude."

Take a look at the review, check out the Digenetics web site, and see what you think. Then, for an objective look, check out this animated game between Blondie and Simple Checkers, showing surprising over-the-board play quality.

Only 2 players in the world have solved this 6x5 puzzle! Can you become the 3rd person to solve it?

So far only Alex Moiseyev and Jim Morrison could solve it.

On a scale of 1 to 10 (with 10 being the most difficult) Alex gave it a 7, and Jim gave it an 8.5. Both enjoyed it thoroughly.

Gerry Lopez, Leo Levitt, Carl Reno and many others have all failed to solve it - even with computer help! A number of players simply thought it was set up wrong!

The solution will be published online here in The Checker Maven on May 7, 2005.

February 1, 2005 update: solved by Albert Tucker! Will you be the next one to crack this toughie?

Ed Gilbert has released version 1.14p of KingsRow, the powerful checker playing engine that lost a squeaker to Cake Manchester last month by the small margin of 1 win, 3 losses, and 630 draws. The new release contains Ed's giant new opening book with over 800,000 positions.

Drop in the Chinook 8-piece database, and I bet you don't beat this one over the board.

Go here and download your copy right away. A review of the new release will appear on my Checker Program Review Page sometime in early 2005.
