This column will appear on Memorial Day weekend; Monday will be Memorial Day, a time to honor the men and women who have sacrificed so much to defend America's freedom. As it is so often and so truly said, "Freedom is not free," and The Checker Maven adds its own salute in honor of the memory of the patriots who gave their all on our behalf.

During the Second World War, checker expert Millard Hopper visited our service men and women to entertain them with checker lectures, lessons, and exhibitions. Mr. Hopper gave some of his problem settings war-themed names, such as his "Solomon Island Slam." Some of the other problem names would today be considered to contain racially offensive language, but back then, America was at war, and we need to be more understanding than critical.

We never found the exact position for the "Solomon Island Slam" so instead we'd like to offer the problem below. There are two possible winning lines, depending on Black's choices, but in both cases White's key first move is the same. Can you find it?

After so many years of publication, we're out of "stroke" puns and find it necessary to do repeats. But the photo above is definitely a harbinger of spring and summer; rowing crews out on the water, enjoying outdoor activity, perhaps after a long winter.

Today's problem is relatively easy and is set with only four pieces per side; it's a little more practical than the more complex, artificial stroke problems.

Horseradish, of course, is a well known condiment, with a sharp taste and sinus-clearing effect. It's often enjoyed with prime rib of beef, on hot dogs, and in numerous other ways. It's not to everyone's taste; you either love it or you don't.

Horse-radish, in checkers (note the hyphenation) is an older term not much heard today that refers to moves that are sharp, like horseradish, but not to everyone's taste, because they are usually unsound or at least questionable in theory. They're all about over the board play; a horse-radish move, even if inferior, may be hard to refute on the spot if you're not familiar with the line.

You won't be surprised to hear that Willie Ryan was a fan of horse-radish, and the following problem comes from a horse-radish line in one of his earliest books.

Is this sort of thing to your taste, or is it a little too sharp? Does it clear your thinking? Give it a taste, and then click on Read More to see the solution.

Technically, it's already spring in the Northern Hemisphere, as the vernal equinox always arrives in March. Whether or not it's warmed up in your location is something else, and since these columns are written some weeks in advance, we really can't say. Hopefully, the long winter is coming to an end for most North Americans. (If you're in the Southern Hemisphere, we realize you're moving into winter, and we can only hope on your behalf that it will be a mild one.)

To herald the arrival of spring, we have an easy speed problem that will entertain without baffling.

We owe today's problem to a certain L. L. Granger, who published it as Prize Problem No. 4 in The Canadian Checker Player nearly a century ago. He called the problem "A Little Mischief" but it turned out to be rather a lot of mischief.

White to Play, What Result?

Black has a mobile, centralized position. Is it enough to win, or can White draw? That's the real question here. These "What result?" problems are a breed of mischief all their own.

How much mischief are you up to? The problem isn't easy; prize problems seldom are. Give it a try, and then click on Read More to see the original solution and modern computer analysis.

Our monthly Checker School column continues today with its series of famous shots in the game of checkers. These are situations that all experts should know and all students should learn, as they do come up over the board, more often than you might think.

Let's look at this month's entry.

11-15 23-19 8-11 22-17 9-13 17-14 10x17 21x14 15-18 19-15 4-8 24-19 13-17----A 28-24 11-16---B 26-23 16-20 31-26---C

A---6-10 is much better here.

B---Turns a relatively small disadvantage into a probable loss. 6-9 would have minimized the damage.

C---A real lesson in the need to keep your head while you're ahead. Instead of playing 15-10 to go on to a probable win, White will now lose!

Getting jumpy waiting for spring to come? Ready for winter to be over even there might be more cold weather and another snowstorm in the offing??

Be patient; it won't be much longer until winter is left behind.

Our speed problem, though, won't require that much patience. It's fairly easy and can surely be solved in thirty seconds. When you're ready, click below to start the clock and show the position. When you're done, jump your mouse to Read More to check your solution.

March Speed Problem (not too hard; 30 seconds)

For February, the shortest month, we're pleased to present another short speed problem from father and son team Lloyd and Josh Gordon of Toronto, Ontario, Canada. It features a practical over-the-board situation and is relatively easy (hence a 10 second time limit).

We invite other readers to submit similar problems, suited for solving in anything from five seconds to one minute. Meanwhile, a big "mahalo" (thanks) to Lloyd and Josh.

February Speed Problem (Easy, 10 seconds)

Today's Beginner's Corner episode deals once again with that "you've got to win it" idea. A man up is usually a win, but short of the expert level, the other player isn't just going to concede; you'll have to show that you know how to win it.

Here's one such situation.

The holidays have sped by as they always do; there's the long run-up, a week or so of family fun and frolics, and then--- it's over, and we face that winter letdown and months of solid, virtually uninterrupted work, school, or what-have-you.

Fortunately, there's a bright spot for readers of The Checker Maven. For some little while, the father and son team of Lloyd and Josh Gordon, of Toronto, Ontario, Canada, have been replenishing our stock of speed problems, with positions from their own games and of their own design. We're presenting the first of these today.

Josh and Lloyd generally assemble problem positions that vary from easy to medium in difficulty, making them perfect for speed problems. This month we'll start with an easy one. You won't have a lot of trouble solving it, and it's quite clever and pleasing. Ten seconds will be plenty of time, we think, although perhaps you may disagree!

January 2014 Speed Problem Easy; 10 seconds

Thank you, Josh and Lloyd, for sending these problems, and we hope that the rest of your Eastern Ontario winter won't be too tough.
