In January we presented a mind-boggler of a stroke problem (click here to see it again). This month, we offer another brain-twister of a different nature. Take a look at the situation diagrammed below, titled Remarkable Block Problem and attributed to an author calling himself "X.Y.Z."
It all reminds us of Crowther's original Adventure game in which "you're in a maze of twisty passages..." But that was "XYZZY", not "X.Y.Z."
And, by the way, did you try to get your computer to solve this one? It's doubtful that any computer program would be able to come up with the solution. Click on Read More for some supplementary discussion on why this might be.[Read More]
1. Solve the problem (of course).
2. Identify the person in the photo (on the left), who is the problem's compositor. You can click on the photo for a full-size version.
February's entry will be what will probably turn out to be the easiest of the three, at least in terms of identifying the person in the photo; we're not so sure about the problem itself! Here it is:
Can you beat the World Champion? The clock is ticking!
(The Maven thanks Brian Hinkle for sending this one along.)
The feature problem for February is entitled The Little Fooler and is credited to Tom Wiswell and Jimmy Ricca. No less an authority than Ben Boland himself called this "a fine original problem." Skilled solver Brian Hinkle took almost a month to crack it.

Here's a problem attributed to O. H. Richmond, and published a little over 50 years back by Tom Wiswell. He called it "Black Beauty":
Now, you'll surely find that this is a neat problem and a "real twister" as Wiswell would say. So solve it, check your solution with the animation here, and then click on Read More to find out what the computer has to say about this problem. It won't be what you think--- or will it?[Read More]
The Checker Maven presents as its most unusual offering for January the following mind-boggler attributed to a Mr. W. Veal. It is a "stroke" problem, that brand of spectacular, if unrealistic fireworks that appeals to some and is anathema to others.
To be sure, the position below is composed and obviously impossible; there just aren't that many pieces in a game, and they could never get into such a contorted distribution. But for the fan of the stroke problem, realism isn't the issue. The whole point is a clever key move or two, and lots of action afterwards.
Now, depending on what computer program you use, you may or may not be able to coax it into solving this for you. But you really should try it on your own. And since the play is mostly all forced, the challenge is more in trying to visualize the moves than it is in actually finding the solution. But the visualization challenge is mind-boggling indeed. Can you make it out or will this just drive you over the edge?
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.
"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.

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:
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:
