### Coffee and Cake

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.

### A January Warmup

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:

### Can You Be The Third Person In The World To Solve This?

an original problem by contributing author Brian Hinkle

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.

### The Challenge of Checker Problems

We've been corresponding recently by email with Brian Hinkle, a highly skilled checker problemist and analyst. We send Brian problems that he solves in a few minutes; he sends us problems that we know we will never solve but we try nonetheless. We end up feeding them to a world-class computer program such as Cake or King's Row for analysis. The computer solves them without missing a beat.

That brings up the question that is often heard about checkers being "dead." The best computer programs today are at an extraordinarily advanced level, very likely beyond the best human players. Computer programs were always relatively good in checker tactics; but now, with enormous opening databases of half a million to a million positions, endgame databases which comprehensively solve endgames of up to 10 pieces, computer programs seem to know just about everything about checkers. The University of Calgary has as its goal the complete "solution" of checkers, and they think they will do this in the next few years. We believe that they will, in fact, accomplish this feat.

But does the fact that a "solution" for checkers exists (or will exist) mean that the game is "dead"? We think that is only true if you are playing against the world-class computer programs that know the "solution." In a game between humans, especially an over the board game, checkers is not and will never be "solved." There is too much challenge and enjoyment in the game as played by mere mortals.

What has this got to do with checker problems? It's simply that these problems, especially the better and more clever or entertaining ones, show the depth of the game. Struggle with a couple of these gems and you'll see what we mean. You'll find that there's a lot left for you personally in the grand old game. Visit Jim Loy's site and start with his beginner's problems. You'll quickly understand.
