Doubling down: You're playing Blackjack at some fabulous Las Vegas casino and you think you've got two great cards. So you "double down" --- double your bet in the hopes of doubling your winnings.
Alas, it's not that simple. While under the best circumstances your chances of winning are almost 2 out of 3, most of the time you'll just double your losses. Those bright lights and free drinks are paid for by someone.
So, how does "doubling down" apply to this week's Checker Maven column? Read on.
Our Checker School columns for the last few months have featured "gem" problems by G. M. Gibson. Today we bring you the concluding entry in the G. M. Gibson problem series, and it's a practical one.
There are two ways to for White to win this. If this were found in a problem competition, that would be kind of a bad thing; dual (or "double") solutions are frowned upon.. But as a teaching position, doubling down (or should we say doubling up) can be instructive, and we're asking you to find both winning lines. Can you double down and do that? Can you find at least one solution? They're closely related, and if you find one, you might just find the other.
Try it (at least twice), and then--- wait for it--- double-click your mouse on Read More once to see all the answers.[Read More]
1987: Korea and Iran were in the news (sound familiar?). Reagan was President. The stock market had a giant meltdown. And IBM's John Akers declared 1987 to be "The Year of the Customer" leaving us to wonder what other years might have been.
But did you know there was "The Year of the Checker"? Well, those exact words weren't used, and it was only the thought of one writer, but the following quote makes our point.
"... this season finds checkers fast becoming one of the leading popular pastimes, with checker clubs being formed in almost every large city in the country. Team matches are going on, checker columns are appearing in the local papers and the year XXXX will witness the greatest checker gathering of all time ..."
Taken from a checker book, we think this rather effectively declares that "The Year of the Checker" was in progress. We challenge you to name the book and the author, and replace "XXXX" with the year that the author referenced. What year was "The Year of the Checker"? (Hint: It certainly wasn't 1987.)
Although the fortune of our game has declined since, some things are timeless, such as the following problem, which appeared in the book cited above.
The problem isn't especially difficult, though it might be better suited to a more advanced beginner than to a novice. See if this is "the year of the checker" for you; find the solution and then click on Read More to see the winning moves and the answers to our questions.[Read More]
Richard Pask's Checkers for the Novice, the print edition of Logical Checkers Volume 1, is now available from CreateSpace and Amazon, and is also available from Amazon UK and Amazon Europe. The 170 page book has been priced very modestly at US $7.49 (exclusive of shipping).
You can download a free PDF version by clicking on the link.
Checkers for the Novice includes substantial corrections and improvements and is the definitive modern guide for newcomers who wish to play checkers well.
 Amazon lists the book with "Richard Pask, Author" and "Bob Newell, Author." This is incorrect. Richard Pask is the sole author. Bob Newell is the editor and publisher.
In our long-running Checker School series, we've featured Ben Boland's Famous Positions in the Game of Checkers. We're almost to the end of that book and this will be the last study from that source. Later, we'll move on to other positions and books of a suitably didactic nature.
It's fitting, then, to be "Dunne" with a position attributed to old-time checker great Frank Dunne.
This isn't especially easy, and in Mr. Boland's notes, he points that out but is most unusually judgmental of a player who didn't find the win. In defense of the fellow that lost, this is an 11x11 position and it's easy to stray from the path.
Fortunately, The Checker Maven will never judge; we only encourage, and in this case, we urge you to find the solution. Don't stop until you're Dunne, and then click on Read More for the usual sample games and analysis.[Read More]
Richard Pask has retired! Actually the photo above dates back to mid-2017, when Richard did indeed retire from his position as an educator.
But retired, for Richard, may mean something very different from what it means to others; this gentleman has been very busy indeed. Last week we published his revised edition of Complete Checkers, and this week we're proud to put forth the first book in his new series, which is called Logical Checkers.
The series, expected to consist of five volumes, will present a layered approach to checker tuition, from novice through master. Book 1 is the "Novice" guide but it contains much of interest even to a more experienced player. Rules and basic principles, tactics and strategy, common endgames, and an initial opening repertoire (for Go As You Please players) are all presented in 127 full-size pages illustrated with 128 diagrams.
Down the road, after the series is completed, we plan to once again offer a combined edition in both electronic and print formats.
We predict that Logical Checkers will do no less than revolutionize checker tuition.
Richard, once again, is very generously giving us his work free of charge. It can be downloaded here or from the Richard Pask page as linked in the right-hand column.
Here's one of the tactical examples given in the book.
It's not that hard; this is, after all, a book aimed at relatively new players. But it's nonetheless pleasing. See how quickly you can find the solution and then click on Read More to see how you did. And be sure to grab your copy of the new book. Thank you, Mr. Pask![Read More]
The weather in the Dorset area, on England's south coast, hasn't been so great this winter. The photo above is of a frozen-over window in Richard Pask's home. Brrr!
But if the cold weather has kept Richard indoors, we are the beneficiaries, for today we're pleased to announce the immediate availability of the second edition of Richard Pask's landmark work, Complete Checkers. This edition incorporates about 100 changes, updates, and corrections. The Checker Maven thanks Mr. Pask for the continuing privilege of publishing and presenting his work to you, the checker players of the world.
Of course, the revised book can be downloaded in PDF format, completely free, either here or from our Richard Pask page, as linked in the right-hand column. The printed edition has also been updated and can be obtained from Amazon's US, UK, and European outlets (although going to the expense of replacing your first edition printed copy is by no means necessary).
Here's an example of a new idea in the new edition.
This is Ballot 102.
Several moves draw here. In the 1st edition, with play attributed to Willie Ryan, Richard showed a draw after 29-25, but in the second edition, 24-19! is presented (also attributed to Ryan). The computer tells us that 24-20 and even 17-13 are also probably draws, although the draws are definitely more difficult than in the line of play after the brilliant 24-19. (For subsequent play after 24-19, refer to the book, game #1748 on page 482.)
But what if White tries a hasty and badly mistaken 31-26? Then we have this:
It doesn't look so good for White, does it? Black indeed has a win. But can you show it over the board? It isn't especially difficult if you know the technique, but it's one of those highly practical things that you simply must know if you're to succeed at the upper levels of the game.
See how you do (are you stuck indoors too?) and then click on Read More to view the solution.>[Read More]
The photo above shows a very narrow drawbridge somewhere in Holland. Now, in checkers there are bridges and draws, and some of those draws are narrow indeed. Today, we'll look, not at a bridge, but at a narrow draw, which we'll define loosely as one that is difficult to find over the board and requires precise play, hewing to a "narrow" path.
We've been exploring the final part of Willie Ryan's Tricks Traps & Shots of the Checkerboard with a series of variations on some rather tricky play. Today, we ask you to join Willie in helping the White pieces find a narrow draw.
Here's the run-up one more time, with just a couple of notes as reminders.
A---Loses. 28-24 and several other moves would draw.
B---Willie claimed that this draws, but the game was lost earlier.
C---Black's winning move was 25-29; now White can draw.
This one is tough, no doubt about it, and the path is indeed narrow and long. Still, it's a really terrific study, filled with checker wisdom. Do give it more than a narrow try before clicking on Read More to see the solution and notes.[Read More]
Last month we presented a "twin" problem by Brian Hinkle. Today's Checker School entry is a bit reminiscent of the "twin" idea. Originally found in Ben Boland's classic Famous Positions in the Game of Checkers, Mr. Boland showed a position in which, supposedly, if Black plays then White wins, while if White plays, then Black wins.
But much to our surprise, we found that, in the original edition of the book, the second member of the twin was in error!
The first problem, which Mr. Boland says isn't that difficult for top players, requires quite a lot of nuanced play.
The second problem, which existed for many years without the correct solution being found, may prove difficult, but honestly, we thought it was relatively straightforward--- if and only if you find the correct first move, something that eluded the experts. (We understand that the problem terms and solution were corrected in a later edition of Mr. Boland's book.)
It's not a "twin" problem; it's more like the "evil twin." Can you solve both parts? If you can, consider yourself a top player, but in any event, clicking on Read More will show you the solutions, several sample games, and detailed notes and analysis.[Read More]
For reasons that we won't go into here, the number 13 is considered unlucky by some. Yet, for us, it's always been just the opposite, and in fact, this week The Checker Maven completes 13 years of uninterrupted, no-fail on-time weekly publication. It's a record we're proud of, and we hope to be able to carry on until our projected wrap-up at the 15 year mark.
To celebrate our 13th anniversary, we turn to Richard Fortman's Basic Checkers and explore one aspect of Ballot No. 13: 9-13 23-19 5-9. It's a reasonably balanced ballot, with maybe a little advantage to White.
(22-18 also a good choice instead of 27-23.)
Black is lucky; there are actually four moves to draw at this point. Mr. Fortman gives 11-15, which is arguably the best, but it isn't the only one. 9-14 or 11-16 or 10-14 instead of 11-15 also draw.
Fortman calls the first two probable White wins but they are all draws, though perhaps rather narrow ones.
For the purpose of today's study, let's consider 11-16 with the likely reply 22-18.
In the book, Mr. Fortman gives 16-20 as Black's next move. This gives White a substantial edge, and though we wouldn't yet call it a White win, Black is going to face a hard time.
What should Black play instead to ensure a draw? Can you sketch out a possible line of play?
We're asking you to match wits with one of the great checker analysts of all time. But it's a great exercise, and, luckily, clicking on Read More will show you the solution.[Read More]
A pretty picture deserves a pretty frame. In our experience very often the frame, if it is one of quality, is more costly than the picture itself.
There's a picture frame in checkers, too, or more precisely, a picture frame position, and it's the subject of this month's Checker School column. Here's the pretty as a picture position.
As you'll see in the solution notes, it was once thought that this was a win for whoever played first, but actually, it's a draw either way. It's somewhat complex, and in fact we've corrected a couple of errors in Ben Boland's published solution. But, you get the picture.
In fact, we invite you to stay in the picture and try to solve the problem. And picture this: clicking on Read More will show you the solution, sample games, and comments and corrections.[Read More]
