Marvin's World


Marvin J. Mavin
Captain, Detroit Doublejumpers

The world of Marvin J. Mavin is featured often in the columns of The Checker Maven, and today, in this extra edition, we're providing you with all the details. How did it happen that (at least in Marvin's world) checkers became America's number one sport, eclipsing baseball and football by large margins?

At long last, you can read the full background story. Click on the link to find out about Marvin's World.

An August Stroke

Early August certainly is thunderstorm season in the Santa Fe, New Mexico area, where one of our Checker Maven editorial offices is located, and strokes of the electrical variety are very common. But today we return to a different kind of stroke, that of the checker variety, and a complex problem that will either please or annoy depending on your skills and predilections. Here's the situation; you will need excellent visualization skills and a good imagination to sight-solve this one.

You'll Get A Kick Out Of This

Today we are pleased to present another crowd-pleasing Tommie Wiswell composition. In Mr. Wiswell's own words, "You'll get a real 'kick' out of this one. The solution is short and snappy and the 'key' move is quite a shock --- to Black."

Here's the position, and we don't claim that it's an easy one.

The Steel Stroke

One thing Willie Ryan could do as well as any checkerist who ever lived was to tell an entertaining story. Here, in our monthly installment from his classic Tricks Traps & Shots of the Checkerboard, Willie relates a couple of anecdotes about a checker position that dates back over 200 years but still astounds us today.

'Now we come to an old chestnut credited to James Steel, of Newcastle, England, identified as the Steel Stroke. When Joshua Sturges reached the diagrammed position below in his "Guide to Draughts" (1800), he overlooked the stroke, playing 17-21 to a draw instead! After the 1905 American-British International Checker Match, former World's Champion Robert Stewart, of Scotland, was persuaded by friends to play "Ajeeb," the automaton checker player, then on exhibit at the old Eden Musee in New York City.

When the position shown below was reached, Stewart moved 12-16 to start the shot. When the "figure" failed to respond, the attendant told Stewart he would have to move faster. Whereupon, Stewart informed the attendant it was Ajeeb's move. The attendant then pretended to wind up the figure, announcing that the game could not be finished because the main steel spring in the machine was out of order!

B:W32,30,29,27,26,25,24,23,19,15,14:B20,18,17,12,8,7,6,5,3,2,1.

A---White has a trap here, for if black moves 11-16, white will win with 26-22, 16-23, 15-10, 6-15, 25-21, 18-25, 27-4.

B---Right after Ajeeb made this move, he developed mechanical cramps. The proper play to draw is: 15-10, 6-15, 19-10, 17-22*, 25-21, 12-16*, 32-28, 16-19, 24-15, 22-25, 29-22, 18-25, 21-17, 7-11*, 30-21, 11-18, 23-19, 18-22*, 19-16, 2-7, 17-13, 22-25, 13-9, 25-30, 9-6, 5-9*, 14-5, 7-14, 27-24---1, 20-27, 31-24, 1-10, 5-1, 14-18*, 1-6, 10-14, 6-10, 18-22*, 10-26, 30-23, and black can draw with care---2. This fine play is by World Champion Walter Hellman.'

1---The King's Row computer program chooses 6-2 instead and finds what looks like an easier draw than Hellman's line with the calculated line of play being 6-2 30-25 27-23 25-22 23-19 14-18 16-12 8-11 19-15 11-16 28-24 20-27 31-24 16-19 24-20 19-24 20-16 18-23 16-11 23-26 15-10 26-31 2-6 and it's clearly a draw---Ed.

2---King's Row agrees that this position is a draw despite Black being a man down---Ed.

Similar But Not Quite The Same


Click on the image for a full-size version.

Can you find a total of eight differences in the two pictures above? It's a classic sort of puzzle, and unless you're rather skilled with images, finding the last little variation is often quite a challenge.

In today's edition of Checker School, we present two "similar but not quite the same" positions. The optical differences are a little easier to find than in our teaser above, but the over-the-board solutions may prove somewhat more resistant.

In both of today's positions, shown below, White is to play and win. We'll give you a small tip: one of the positions is quite a bit easier than the other, despite similar appearances. Not much of a tip, we agree, but we are known to be notably stingy in the hint department.

Fourth of July Picnic

Tommy always looked forward to going to the Fourth of July Picnic with his family. There would be hot dogs, hamburgers, watermelon, ice cream cones, and a host of summer treats. There was the three-legged race, the pie-eating contest, and more fun than could ever be imagined, topped off with an exciting display of fireworks. Tommy's home town in Florida really knew how to celebrate America's birthday.

But this year was even more special. Tommy was going to play in the adult section of the Fourth of July checker tournament! Normally, he would play in the elementary school section, but this year he had managed to get permission to go straight to the top and play with the grownups.

Now, Tommy had been studying checkers every Saturday morning with Uncle Ben (see our Uncle Ben's Porch series of columns). Uncle Ben wasn't really his uncle, but everyone called him that; and under his mentoring, Tommy had come a long way with his checker skills.

Uncle Ben was at the picnic, of course, but as a full-fledged professional wasn't allowed to enter the tournament. Tommy wanted to make him proud and was determined to play well. But playing against experienced adult checkerists was no easy assignment.

The tournament was "single life" elimination. If you lost your round, or if your game was a draw in two rounds, you were out of the competition.

The first round was about to begin. Tommy was paired with a very tough opponent, 47-year old insurance agent Bob Fernastus, one of the top adult amateurs in the area. Bob was captain of the county champion recreational checker team, the Mutual Farm Draughts Oxen.


Bob Fernastus

They met at their assigned board. "Pleased to meet you, Mr. Fernastus," said Tommy politely as they shook hands. "Same here, young man," said Bob in return; was he perhaps being just a bit condescending to his much younger opponent? But just at that moment, the tournament director gave the call, "Start your clocks!" and the tournament was underway.

Tommy had White and the game unfolded as follows.

Black: Bob Fernastus
White: Tommy
1. 12-16 22-18
2. 8-12 25-22
3. 16-20 24-19

11. 1-5 18x9
12. 5x14 29-25
13. 11-15 25-22
14. 15x24 28x19
15. 3-7 32-28
16. 2-6 (see diagram) 28-24
17. 8-11 22-18
18. 6-9 18-15
19. 11x18 21-17
20. 14x21 23x5

22. 20x27 31x24
23. 21-25 5-1
24. 11-15 1-6

Draw Agreed.

"Wow," said Bob, you really had me going there! Great game, Tommy, but do you realize you missed a win at move 16?"

Tommy, pleased to get a draw against a highly skilled adult player, looked puzzled. "A win, Mr. Fernastus? Really?"

"Yes, Tommy, you could have won the game! Do you want me to show you?"

"Yes, sir, if you would ... I had no idea ...."

"Well, then Tommy," Bob continued, "Here it is."

Marvin Visits Manchester

It was the All-Star break during this year's National Checker League season, and as part of the week-long festivities, Marvin J. Mavin, checker star and team captain of the Detroit Doublejumpers, was doing a promotional tour in Great Britain.


Professional Checker Star Marvin J. Mavin

Certainly it would come as no surprise to know that one of the stops on Marvin's tour was the city of Manchester, truly one of the checker--- or should we say draughts--- capitols of England. Marvin had undertaken to play a simultaneous exhibition against the members of the British Amateur Championship team, the Chorley Checker Chaps. A fivesome made up of star draughtmen, their roster was impressive: Matthew Eek; the eminent mathematician and team captain Dr. John Algeeber; Donald Oligarch; Melvyn Emerald; and Eddie O'Gollie.


The Championship Team, The Chorley Checker Chaps

The match was taking place at that noted local enterprise, the Multicorn, where it was said that the beer and ale were of the highest quality and the atmosphere most suited for a serious match of draughts.


The Multicorn, Site of the Match

When told of the arrangements, we understand that Marvin approved wholeheartedly, even though his coach had warned him to maintain a positive image and keep in mind the public relations purpose of the tour: in other words, keep away from the beer, stay sober, and play winning checkers.

There were a couple of problems with that directive, however. First, Marvin, being more than a bit of an iconoclast, always had shall we say a bit of a problem in following the directions of higher authorities. Second, as we all unfortunately know, Marvin was rather partial to a good pint of beer, and was known to partake at inappropriate moments, and in fact at any moment possible. (Recall our earlier Checker Maven story in which Marvin lost a game to his arch-rival, Dmitri Tovarischky, after having enjoyed Octoberfest beverages a little too freely.)

Marvin was in full form for today's exhibition, and he would need to be at his best; the Checker Chaps were no easy targets, being the best amateur players in England. The playing room was ready; the Checker Chaps were seated at their boards, and the room was filled to overflowing with enthusastic fans.

The match was about to begin when to everyone's surprise (or perhaps to no one's), Marvin suddenly called for "a pint of Base Ale all around."

The Checker Chaps did their best to mutter polite refusals but not a few of the fans, and Marvin himself, soon had in hand a frothy mug of ale. Play began, and it quickly became evident that the Checker Chaps would provide Marvin with stiff competition.

Marvin quickly won his game on Board 4 after taking advantage of a positional error. Board 5 ran into a quick draw, as did Board 3. On Board 2, Marvin lost a piece in a tricky exchange and graciously (at least by Marvin's standards) resigned the game, quickly calling for another pint of Base Ale to assuage his disappointment with the loss.

The game on Board 1 with Dr. Algeeber would decide the match. It had played out thus far as follows:

Black: Marvin J. Mavin
White: Dr. John Algeeber

1. 9-14 24-20
2. 5-9 22-18
3. 11-15 18x11
4. 8x15 25-22
5. 7-11 22-17
6. 4-8 17-13
7. 2-7 29-25
8. 1-5---diagram

The situation was tense. Dr. Algeeber wanted to win the game and take the match on behalf of his team and the home town fans. Marvin, of course, as a star professional player, had a reputation to uphold. But Dr. Algeeber was an expert in his own right and an opponent not to be taken lightly.

Of course, one had to ask if Marvin should really have called for that third pint of Base Ale, "to clarify his thinking" as he told the barmaid.

Dr. Algeeber had again declined, this time noting in a somewhat pointed manner that "draughts of ale and draughts over the board really don't mix all that well, you know." The British team captain was now on move, and realized that he had chances to perhaps pull through with a win. The board position was as follows.

BLACK

WHITE
White to Play and Win

W:W32,31,30,28,27,26,25,23,21,20,13:B15,14,12,11,10,9,8,7,6,5,3.

Marvin, as usual, was fidgeting in his chair, taking frequent sips from his mug. Though he found this all more than a bit annoying and distracting, Dr. Algeeber, being the gentleman that he was, refrained from complaining. Finally, though, he allowed himself a bit of a smile as he made his move.

Would you have been able to win this position against someone with Marvin's finely honed professional skills? Would you have been able to keep cool despite Marvin's constant fidgeting, muttering, and slurping of ale, or would you have been tempted to dump a water pitcher over his head?

Well, we certainly wouldn't recommend something so impolitic as the latter, but we do recommend that you try to find the winning move, and then click on Read More for the conclusion of the story and the solution to our problem.

A Study In Structure

In this month's excerpt from Willie Ryan's unmatchable Tricks Traps & Shots of the Checkerboard, we see a situation that Willie characterizes as "not so impressive as most of the other items." Of course, Willie has extremely high standards, but we can certainly say that we're impressed with this little gem! Add in the fact that it is of practical use, and you have something that certainly ought to command our attention. Here's Willie to explain it all to us.

"The following stroke theme is not so impressive as most of the other items in my compendium, but it is one of major importance, and of a type most likely to be overlooked in crossboard play. The game itself was adapted from one I played with 15-year-old Leonard Rosenfield, of Boston, who has all the promise of a future World Champion.

Leonard Rosenfield vs. Wm. F. Ryan.

C---Down the wrong alley! The correct thrust is 4-8, 26-23, 8-12, making the draw play shown in Note A."

Small, Square, Two Inches of Ivory

The famous British novelist of the late 18th and early 19th century, Jane Austen, spoke of her writer's canvas as a "small, square, two inches of ivory." By this she seemed to have meant that her works were limited in scope and in some sense "miniatures" based on the society in which she lived.

But this is a checker column, not a literary review, and we bring up Miss Austen only as a point of comparison to miniatures in checkers. They too deliberately limit their scope, but, like Jane Austen's famed novels, have no lack of intricacy, depth, and ultimately, charm.

Today we publish a Checker School study taken from the pages of Ben Boland's Famous Positions in the Game of Checkers. It's indeed a small square of ivory with much appeal and value. Here's the position.
