The Checker Maven

The ACF Nationals


Checker Action at the 2007 Nationals

Virtually every week The Checker Maven brings you a puzzle or a problem to solve; something to enjoy and learn from, and which demonstrates the endless depths of our game of checkers. But this week is a little different. Today instead we present for your pleasure two excellent games from last year's U.S. National tournament, which took place in July 2007 in the fabled city of Las Vegas. We're also shamelessly pitching the 2008 National tournament, in the hopes that you will attend if you can or donate a little something if you can't.

Our spotlighted games from the 2007 tournament were sent along by Colorado Springs checker expert Bob Murr, whom we're proud to say has been a reader and supporter of The Checker Maven since the very beginning. In the 2007 tournament, Bob played a pair of games against the Irish expert Tommy Canning, famed for his skill as a correspondence player, but equally formidable in an over-the-board contest. The games below were annotated by Bob. We hope you enjoy them.

A---This move has a bad record strongly favoring White; the 10-15 exchange is favored here, followed by either 26-23 or the 24-19 exchange to an even game.

B---11-15 seems better.

C---30-26 is the power move here followed by 2-6, 26-22, 3-7, then the 24-19 exchange appears to win.

D---During the game, I thought this would equalize but it offers White a powerful advantage.

E---31-27 is the power move although this also appears to win.

F---This allows Black an even game, 7-2 wins by 19-24, 28-19, 15-24, 2-7, 24-28, 7-11, 28-32, 31-26, etc. WW.

G---Black was very fortunate indeed to escape.

Andy's Annihilator

In our latest installment from Willie Ryan's Tricks Traps and Shots of the Checkerboard, we present what has to be the most stunning and spectacular position thus far--- and that's saying a lot. Without further ado we'll let Willie tell us about it.

"World's Champion Andrew Anderson is generally con­ceded to be the discoverer and early coach of James Wyllie, although there is no evidence on the records to indicate that the 'Herd Laddie' ever acknowledged Anderson as his teacher. The great Anderson played five torrid matches with Wyllie between 1837 and 1847, winning four of them, losing one. This may explain why the caustic Wyllie was reluctant to bestow any credit upon his master. A refined and quiet-mannered gentleman, Anderson was versatile as a player and as an analyst. It has been said that none of the trunk games in his Guide has ever been corrected. Among Anderson's best known analytical sparklers is this instructive sortie on the Souter opening. Proceed with:


9-14 23-19 11-16
22-17 6- 9 17-14
11-15 17-13 16-23*
25-22 2- 6 31-26---F

29-25 14-18 21-14,

B:W32,30,28,27,26,25,24,22,14,13:B23,18,15,12,9,8,7,6,5,3,1.

A---In a match game between Robertson and Wyllie, the former used 11-16 at this point, and the following sensational play ensued:


11-16 27-23 11-15 31-27 11-27 26-23
24-20 19-24 19-16 5-9 19-15 19-26

17-13---B 8-11 22-17 8-12---C 13- 6
4-8 28-19 3-8 20-16 1-10

B---White dare not attack the piece 27-23, as 5-9, 23-16, 9-13, in reply, ends all organized resistance, and black wins.

C---At this move, one of Wyllie's cronies, Peter Rule, entered the playing room, and after hastily taking inventory of the situation on the board, exclaimed, 'My, Mr. Wyllie, how did you ever get into such a scrape as this?'

'I am a piece ahead,' was the pert reply. Then Wyllie moved 20-16, proceeded to give away six men as fast as Robertson could take them, and acquired a draw amidst loud salutes of general ad­miration.

D---A splendidly played crossboard game, which is worthy of close analytical study by all grades of players.

E---A tricky but untenable move, which requires black to meet it with exacting play. The correct move here is 26-23, as exemplified in Mclndoe's Slingshot (previously published here --Ed.).

F--21-17, at this point, would be crushed by 23-26, 30-23,15-19, 23-16, 12-19, 24-15, 10-19, 22-15, 9-18, 31-26, 7-10, etc., with black winning."

Make no mistake, this one is a real shocker, and a genuine challenge even to a top player. Can you do it? Don't get annihilated; click on Read More to blast your way to the incredible solution.

Second Position

Our ballerina above is showing good form in demonstrating Second Position. We'll wager that ballet's Second Position is known to more of the general public than checker's Second Position--- but we'll bet the margin is small.

We continue with our review of the basics in this month's Checker School column, drawn as usual from the erudite pages of Ben Boland's Famous Positions in the Game of Checkers. And what can be more basic than Second Position? You may ask why we even bother with such an old warhorse, as it's been presented in virtually every basic checker textbook since time immemorial.

If you've mastered this position, we'll accept your argument, and you can browse on over to your favorite alternate checker site. But how many of us have really mastered all the nuances? Today, we take you on the backstage tour of Second Position, and by the time you're done, you'll be able to literally dance your way through this tricky but important ending.

Try your hand at the following progressively more difficult three examples.

A Bit Too Advanced

Sartre's L'Être et le Néant is a bit too advanced for most folks, let alone for the reader pictured above. We feel that there is an apt analogy to some stroke problems, which seem every bit as complex as the French philosopher's famous work on l'ontologie phénoménologique. This month's selection certainly can be described as complex; or again, making further reference to the existentialist canon, perhaps incomprehensible.

Fortunately, you can try out our problem without need for a French to English translation.
