Italy's Mount Vesuvius, an active volcano, has a storied history; the painting above illustrates its eruption in the year 79 C.E., a catastrophic event that obliterated the Roman cities of Pompeii and Herculaneum. The painting is by Jacob Philipp Hackert and dates to 1845; in 2009, it sold at auction for a rather steep 138,000 Euros.

Now, in checkers, there is the famous (or maybe not so famous) Vesuvius Shot, which "buries" 14 pieces from both White (Pompeii, if you wish) and Black (Herculaneum). But there's something else that's buried here. Checker enthusiast Manon Pruitt, of Nashville, North Carolina, used the Kingsrow ML computer engine to help dig it out, and we extended the analysis to find something deeper still. The starting position comes from play in Wood's Checker Studies.

B:W13,16,21,23,24,25,27,29,30,32:B2,3,5,6,7,11,14,15,18,20.

The following continuation is given in the original publication:

At this point Mr. Pruitt found, using KingsRow, that 25-21 instead of 25-22 would draw, thus overturning the problem conditions. But we investigated further and determined that in fact the published move, 25-22, also draws! There is a flaw in the ensuing published play. Here's position after 25-22.

Black would now win if the above play were correct, but it's not. Your challenge is to correct it.

It's clear in the picture above that those two are attracted to each other, but they are equally clearly agonizing over who should make the first move.

In a checker problem, the first move is often critical, too.

We've written before about the excellent practice site Checker Cruncher, and we do stop by there every so often to try our luck on the site's large collection of interactive checker problems. We highly recommend it.

Site creator Brooks Thomas kindly gave us permission to republish Checker Cruncher problems that we find interesting, and the one below got our attention.

Naturally, it's all about that first move. There's only one move to win; everything else will draw or even lose.

In his poem Stopping by Woods on a Snowy Evening the immortal American poet, Robert Frost, wrote these equally immortal words:

The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

Today's Checker School "Gem" problem is by the somewhat less immortal checkerist Miles R. Smith. It's really quite nice, and we wish history had preserved more about Mr. Smith.

Black is a piece up, but looks to be in a precarious situation; he can't avoid giving the piece back, hoping for a draw ... or is there another way? Can Black manage to still win this one? Miles to go before Black sleeps ...

Looks good, doesn't it? It's "Super Easy Pot Roast" from someone who calls herself Chef Savvy and, checking over the recipe, it indeed looks like a great dinner made with minimal effort.

Is there such a thing as a great checker problem, solved with minimal effort? The most pleasing problems seem to be on the more difficult side, but there's another way to look at this: a simple problem solved very quickly can also provide a good measure of satisfaction.

To this end, we've decided to bring back our Javascript clock for perhaps just one time, as today's speed problem is in the category of "super-easy," and we don't want to spoil things by putting the problem diagram in-line. So you'll need to click below and then you'll have five seconds to beat the clock! No worries, that's definitely enough time.

In the world of American crossword puzzles, each week renowned cruciverbalist Stanley Newman publishes the "Saturday Stumper." It's a very hard puzzle, often substantially harder than the one in the Saturday New York Times, which is in itself a real challenge.

Checker problemist Brian Hinkle has come up with a "stumper" of his own, and has kindly shared it with us. Let's have a look.

As is typical with Brian's compositions, finding the first move is the real key, although even then you've still got to demonstrate the draw. But "Stumper" actually has two solutions. You may not necessarily be stumped in finding the first solution, but finding the second solution is truly a "Saturday Stumper" of our own.

Will you be stumped, not just on Saturday but in the ensuing days? Consider yourself a good solver if you find the first solution, and an amazing one if you find the second. Clicking on Read More, of course, will show you everything.

Tough steak? Bit off more than she can chew? The steak might possibly have been a little less tough, and more appealing, if it was tenderized and ... cooked.

Tough in checkers, of course, means something different (and so does "cooked" but that's a story for another day). It seems like we've published quite a number of tough problems lately, but hopefully they've been interesting and instructive. With that out of the way, we're going to publish one more. It's a good one, and although we've lost track of the source, it's nonetheless pleasing--- and tough.

Yes, Black can win this position with skillful play and quite a bit of patience. That's by way of saying that the solution is rather long and requires careful application of technique. Are you tough enough to stick it out and gain the win? But when you're ready, it won't be very tough at all to click on Read More to see the solution.

No, not like that! Computers can be frustrating sometimes, but the suggestion to 'hammer it out' shouldn't be taken literally.

Sometimes checker games can be frustrating, and you've got to hammer out a solution. In today's Checker School entry, continuing our series of 'gem' problems, we have something composed, appropriately, by Wm. M. Hammer.

If you're Black, you might be frustrated at the difficulty of hammering out a win. If you're White, and a man down but with a centralized position, you might be frustrated at the difficulty of hammering out a draw. Yet a draw is there.

Leap Year won't come until next year, so February remains a short month. It's always seemed a bit unfair to us. Even though there are only 28 days, the rent or the mortgage or the condo fees remain at their full amount, as do the cell phone bill, the cable bill ...

We're certainly not going to solve that problem here, so maybe we'd best concentrate on a checker problem. It's a short stroke for a short month, and we think you'll find it to be on the easy side.

We found A Fantasy in an old checker publication, without any attribution. A Fantasy postulates a game between an Egyptian and the Wizard of Oz, played in the year 2,000 B.C.E.

Well, The Wizard of Oz wasn't published until 1900, but we're willing to suspend disbelief and overlook this nearly 4,000 year time gap, and we won't even get into the fact that our current form of checkers wasn't quite on the scene yet, either. We'll just start with the run-up to the problem position.

Loses. An easy mistake to have made, but 7-10 would have drawn. We suspect Black didn't like the looks of 7-10 14x7 3x10 32-27 1-6 18-15 4-8 but Black is safe: ... 27-24 (31-26 10-14 26-22 14-18! 23-14 16-32 Black Wins) 16-20 31-27 12-16 19x3 10x26 to a draw.

Today we're pleased to announce the release of the second volume in Grandmaster Richard Pask's projected five-volume Logical Checkers series. Volume 2 is entitled Freestyle Expert.

Following on the heels of the highly successful first volume, Checkers for the Novice, the new book delves deeply into tactics, endgames and mid-game formations as well as landings and various freestyle (go-as-you-please) openings.

You can get the new book in its first electronic edition from the Richard Pask page as linked in the right column, or directly here. Through Mr. Pask's generosity the book is provided completely free of charge. The book runs to about 180 pages with over 150 diagrams and numerous illustrative games.

To demonstrate one small part of the content of this wonderful new book, here's the run-up to a sample tactics situation.
