The holiday season is in full swing and we extend greetings and best wishes to all of our readers. No matter which holiday you celebrate, may you find happiness and blessing.
We thought we'd present a little longer study this week. Perhaps you'll have some extra spare time over the holidays (or perhaps not!), but in any case it's a good one. The problem situation is based on a game contested in Markham, Ontario, on April 15, 1889. The players were checkerists Fleming and Wright, and the game and variations appeared in a relatively short-lived periodical called The Chicago Evening Lamp.
Perfectly played thus far, and we've reached the end of the KingsRow opening book for the game as actually played.
This seemingly natural move actually loses. 25-22 would have been correct to draw.
Here the Lamp called the game a draw and showed a drawing line. But it's actually a Black win.

It was Opening Day for the National Checker League as the 2019-2020 season was about to begin, and Marvin J. Mavin, Captain of the defending champion Detroit Doublejumpers, was ready.
August training camp had been rough, with lots of physical and mental training. But Marvin had to admit it felt good to be in top shape, even though he thought the coaches had been pretty tough on him. No beer for a whole month, and running laps constantly.
This afternoon, the Doublejumpers were facing the Seattle Single Corners at Starbugs Stadium in Seattle. A sellout crowd of over 50,000 was on hand to see what promised to be an exciting contest.
Marvin, on first board, was paired up against the Seattle captain, a short, squat fellow that just went by the name Sluggo. In high school and college, Sluggo was a champion weight lifter and wrestler, but he was so good at checkers that he decided to take a pro contract. Still, one look at him told you that he had definitely kept up the physical training.
Word had gotten around the League about Marvin's experiences in training camp this year, and Sluggo started to ride Marvin as soon as they took their places across the checkerboard.
"Heard you had to run some laps," Sluggo said. "Must a been tough for a wimp like you." Sluggo laughed, a deep, nasty sound that had intimidated many an opponent both over the board and in the ring.
"Yeah, well, unlike you I got a brain," Marvin said.
"Not very original," Sluggo replied, "and anyhow you won't have one yourself after I bust up your head."
"Hey! Are you threatening me? You can't do that!"
Sluggo looked Marvin right in the eye. "Really? Whatcha gonna do about it?" Sluggo raised his clenched fists to chest level.
Marvin involuntarily took a step back, but just then the referee's whistle blew and the call "Play checkers!" resounded across the field.
Sluggo stuck out his hand for a handshake, but Marvin didn't take it. He was afraid Sluggo would break his fingers. That got another low laugh from Sluggo. "Have it your way, little boy," he said. "I'll beat you on the board, over the board, and into the board."
The game proceeded as follows. Marvin had Black and Sluggo had White.
Loses. 25-22 was correct.
Marvin chuckled. "Hey, you did pretty well up to now--- for a lamebrain. But that last move is gonna cost you the game."
"Oh yeah?" replied Sluggo. "Sez who?"
"Sez me, Marvin J. Mavin."
"You're dead meat. Nobody beats Sluggo."
Marvin chuckled again. "We'll see about that," he said, and made his move.
Can you beat Sluggo? No, not on a wrestling mat, but over the board? See if you can find the win and then slam your mouse on Read More to see the solution and the conclusion of our story.[Read More]
Marvin J. Mavin, Captain of the Detroit Doublejumpers, a highly ranked team in the National Checker League, was on summer vacation. The League wrapped up the World Series of Checkers in May, and players were off until training camp started up at the beginning of August.
Ten weeks of vacation. He'd spend some of it with his girlfriend Priscilla, although she could only get away from her corporate executive job for a week at a time, and only now and then. He'd spend four weeks doing outreach work in the inner cities. And he'd spend three blessed weeks at a lake cabin, kicking back and thinking of little else but when to pop open his next beer. No cell phone. And definitely no checker board.
Except it didn't work out exactly like that.
Marvin booked a cabin in Idaho under the name of John Smith. He thought that was pretty clever. Of course, he was a national sports figure and pretty easy to recognize, but he always looked for a cabin that was out of the way and isolated, and then he stuck pretty much to himself, arranging to have the refrigerator well stocked before his arrival, so that he could just hang around the cabin, walk down to the lake, and not be bothered by anything or anyone.
It must have been on the third or fourth day when he saw a familiar looking figure walking further down the lakeshore. Now, Marvin's cabin was indeed well separated from the others, so it was pretty far, but the figure was quite unmistakable. Marvin just hoped he hadn't been noticed, and he was pretty careful to check each time he went to the lake thereafter.
Two evenings later, Marvin had just finished with dinner --- he had plenty of microwave meals in the cabin's freezer --- he was about to open another beer when there was a knock at the cabin door.
Marvin was pretty surprised. Could it be the camp manager? No one else was supposed to bother him. He got up, opened the door, and saw ---
Yes indeed, Dmitri Tovarischky. The guy he had seen further down the lakeshore. The guy who was his archenemy, a former Soviet champion who was asked to leave the National Checker League over a gambling violation, and who now stalked the star players.
"Ah, Checkers Boy. I see you other day by lake. How conwenient we are staying in same campsite," Dmitri said. "Maybe coincidence, maybe not, eh? I come in now, da?"
Dmitri entered before Marvin could reply.
Marvin made a mental note to later find out who leaked his vacation plans.
"We play one game, da?" he said. "Play maybe for wodka. I win, you give me couple bottles Stolichnaya. You win, I give you same thing, only you don't win, this I know already."
"I ain't got no 'wodka,' Pinko. Never touch the stuff. Now leave and don't come back."
"Ah, Checkers Boy should not be rude. I have little set here, I put on table." Boris quickly got out a portable checker set and made it ready. Marvin could tell it was going to be hard getting rid of him. "Maybe play for hundred bucks?"
So that was what it was all about. Dmitri was an inveterate hustler. Marvin replied, "Okay. One game. A hundred bucks to the winner. Nothing on a draw. But no matter what you get lost permanently."
"Easy money for me," Dmitri said. "Deal."
The two of them sat down and the game began. Outside, the sun was setting over the lake and the air was cooling. It was a beautiful Idaho evening but neither of them noticed.
Dmitri played Black and Marvin had White.
26-22 was weaker than 25-22. Perhaps Marvin was throwing Dmitri a bit of a curve ball? But Dmitri missed the opportunity to reply with 15-18.
"Hoo, Checkers Boy, you are making stupid move. Why you not play 23-19? Now Dmitri have big winning game!"
"Dmitri can even win by playing of 12-16. So many ways to win, so nice, da?"
Marvin, for his part, was starting to sweat. How could he have made such a blunder?
"Uh, hey there Commie, I think you blew it. You even mentioned 12-16 your own self, why didn't ya play it?" Marvin said.
"I am still going to win, Checkers Boy, do not worry yourself." But Dmitri sounded a bit less confident.
At this, Marvin started to laugh. "Nice try, get an early king, that's what you think? You shoulda played 8-11, pal. Now you lose."
Does Marvin now have a win on the board? Did Dmitri make a huge blunder in his own right? Study the position and see if you can find the winning moves. This one actually falls on the easy side. When you're ready, click on Read More to see the solution and the conclusion of our story.[Read More]
Two wrongs don't make a right, we're told, and if so, surely three wrongs don't, either. A third wrong will only lead to even more trouble--- or in the case of our game of checkers, a loss--- and that leads us to this week's four-fold problem.
We'll look at a published game from years back, in which three wrongs weren't counterbalanced by a right (until today, at least).
At this juncture, White played 23-18, and annotator Gary Garwood called it a weak move. He suggested instead 31-26 or 22-18. But these moves are just as bad. All three of them lose. Three wrongs, no right. But in fact there is a right move and White can obtain a draw here.
Can you find the correct move to draw for White, and then (for extra credit, if you will) show the Black wins for all three incorrect moves? It's a tall assignment, but one that will give you quite a bit of checker insight.

Last month we presented the first game of Watson's exciting match against Alex Moiseyev, which ended in a draw. This month we'll look at the second game of the round. Will Alex come roaring back?
Watson says: "This game I took the white. I actually like the white side in this opening. We began the game. No unexpected moves. Again, I felt good about the game."
22-17 or 27-24 should be played here instead.
Loses the advantage; 16-20 would have retained it.
Watson thinks this is a key moment: " ... the turning point in this game came at move 12 (27-24). This set up was what my Dad used to play all the time against me. He liked it. I never thought much about it. However, when this move came up, I was thinking my Dad was watching. I could almost hear him saying, 'Move there, Watty.'"
32-28 is considerably better.
7-11 was better. The game is now back in the KingsRow opening book.
Watson now thinks the game is decided: "The next move to change the game in my opinion was 19-15 exchange. To me, this was the winning move. He never recovered."
May lose; 12-16 was correct. But let's let Watson describe what happened:
"The next key move, in my opinion, was 15-10 ... By this time, Alex was in serious trouble ... I did not see a single good move for Alex. I saw my win. I was happy. I think Alex saw no way out.
11-15 was a little better.
"I do not know why, but it seemed like someone was nudging me. The voice was saying 'offer the draw.' I was thinking the game is almost over. I have it ... But I kept thinking I needed to offer (the) draw. I cannot fully explain why I offered the draw except to say at that point, I was very happy to get a draw against the World Champion. I knew three things. It had been a long day and I was tired. I knew that Frank and Mary (the hosts) had been very patiently waiting for us to finish. I knew I had a 700 mile trip ahead of me that day ... So I said to Alex, 'Would you like the draw?' Alex looked up at me, surprised. Alex could see it was over. He smiled and said, 'Yes, I would. Thank you.' We shook hands and that was it. It was a very good feeling for me."
Black to Play; What Result?
What do you think? Should Watson have taken the draw, or is there a White win? What is Black's best continuation? Is there a way for White to go wrong and allow a Black win?

Suppose you're a Master level checker player. You're at a tournament and suddenly you find yourself matched with someone who held the World Championship for many years. An intimidating prospect? Certainly you're good, but this guy is good.
Now, imagine instead that you're in the Minor category? You're still in all likelihood a pretty good player, but ... two games against Alex Moiseyev?
Would your instinct be to make a hasty exit from the tournament room, maybe even to catch the next flight to some remote location? Or would you stick it out, expecting to take your lumps and just hope you don't look too bad?
This was almost exactly the prospect faced by Watson Franks, who told us a story of courage and accomplishment from which we can all learn something. Watson didn't run; he sat down and played.
Watson sent us a very interesting and detailed account of his adventure, and while we can't run it all in our weekly columns, we'll put it online in its entirety at the conclusion of this two-part series.
How did this all come about? Watson tells us:
"This past October, 2016, my wife encouraged me to go to the Alabama State Tournament ... at the beginning of the tournament ... they decided they wanted to do a Round Robin ... The Master Players realized that in order to have a Round Robin Tournament, they would need to have eight players ... they only had seven signed up ... I volunteered to move up ... They were appreciative ... very few thought I would get a draw, much less a win against any of the master players."
But Watson did quite well in the early rounds, surprising everyone with his results, including, we believe, himself: he racked up six draws and six losses against six different Master players. (If you don't think that's fantastic, try getting even one draw against one of these champs.)
In the final round, though, he was inevitably matched with Alex Moiseyev. Did he panic?
Here's a little of Watson's narrative:
"Everyone knew I would play Alex the final round. I remember, one of the contestants told me in joking, 'If you were to beat Alex, that would be more of an upset than Trump beating Clinton.' I told him, 'Strange things can happen ... on any given checker board.'
"Alex and I sat on the far side of the room. There was no one around us. It was very quiet. Alex shuffled the 3-move opening cards. In my mind, I knew it would be a good opening. By good opening, I mean one that I was very familiar with. Sure enough, the opening was 11-15, 24-19, 15-24. A 'Go As You Please' opening!"
In the first game, Watson had Black and Alex had White.
End of KingsRow opening book.
May lose; 20-16 was correct.
Gives away the advantage; 6-10 might likely win.
14-9 would have been a sure draw.
The game was left here as a draw. Watson tells us:
"The game reached a turning point. I thought I had (a) decent position. I was pleased with my shape. I knew what my next move would be. It looked very good for me. He (Alex) looked at me and said, 'Would you like a draw?' I looked at the board for a bit. I said to him, 'If you think this is a draw, then itís a draw. But I think I have very good shape.' He said, 'It looks drawish.' Of course, I could have kept playing if I had wanted to do so. It was my choice to accept (the) draw. I could have made a bad move and lost the game. But at the point of draw, I realize now that I had (a) winning position. I was very proud of that game."
So what do you think? Could Watson have won the game? What about his fear of possibly making a poor move and losing?

At the end of May of this year (2017) your editor had the great pleasure of visiting with Mr. Richard Pask and family at his home in the town of Chickerell, in Weymouth, on England's southern coast. Mr. and Mrs. Pask, and their son Robert, are delightful and hospitable people, and it was a very memorable visit indeed.
Mrs. Pask, a musician and teacher, is also a talented gardener and keeps a wonderful English garden, the likes of which are seen only in movies.
Of course, we talked checkers, and Mr. Pask showed us through his library (shown above), packed with checker literature and checker memorablia. Our discussions ranged far and wide, continuing over dinner at a traditional English pub, The Turk's Head.
We asked Mr. Pask to tell us of his favorite personal game, and he said it came from the 1985 Scottish Open, where Mr. Pask had the White against Danny Shields with the Black.
A likely loss (already)! 11-15 or 11-16 would have been correct. Mr. Pask points out that this position can also arise from the opening sequence 1. 9-13 23-19; 2. 10-14 27-23; 3. 7-10?.
26-22 instead keeps the advantage.
The game has now reverted to a probable draw, although the actual play could be difficult over the board.
Probably loses. 8-11 would be a narrow draw.
9-14 was better; Black is surely lost.
Grandmaster Pask was able to find the win in this position. Can you? We'd rate this one as about medium in difficulty; a little effort will be rewarded. See how you do and then click on Read More to see the solution.[Read More]
This column will appear on January 2, 2016. You've had Friday off from work, most likely, and you've hopefully shaken off any New Year's Eve excesses, had your fill of football games, and are ready to settle down to a little checkers to get the new year rolling.
Today we present a full game based on the Single Corner opening. It comes from master play from an earlier day. There are two parts to our checker problem. First, here's the whole game, without commentary.
11-15 22-18 15x22 25x18 12-16 29-25 9-13 25-22 16-20 24-19 8-11 19-16 4-8 16-12 11-16 18-14 10x17 21x14 6-10 22-17 13x22 26x17 8-11 30-25 11-15 23-19 15x24 28x19 16x23 27x18 1-6 25-21 10-15 18x11 7x16 31-27 16-19 32-28 2-7
When originally published, this was correctly left as a Black win (with White to play). Now, the first part of our problem is to demonstrate the win. If you're any sort of advanced player, you'll be able to do this easily enough. If you're a non-expert, it's an excellent exercise in winning a won game.
The second part of the problem is much harder. Can you go back into the game and find out where White went wrong? Again, experts will realize quickly that this line in the Single Corner is not so common. But there's one move that can definitely be said to lose. Can you correct the play?
You'll need to get out your board for this one; we recommend that instead of a computer, as we don't want you to be tempted to simply look at computer analysis.
Will this start the year off right? Only you can say. See how you do and then click on Read More to see the solutions.[Read More]
Dr. Hillary Silverfish stared and pointed at Marvin, the intensity of her gaze frightening and chilling. Close-cropped dark hair added to the effect. This was one tough customer.
"Prepare to die," she hissed.
Marvin J. Mavin, sitting across the checkerboard from Dr. Silverfish, pretended not to be intimidated, but if the truth be known, he was terrified. Even though Marvin was team captain for the Detroit Doublejumpers and one of the National Checker League's top players, Dr. Silverfish was a formidable opponent, and her patented stare was one of her most feared weapons.
The Doublejumpers were playing an exhibition match with San Diego Liberal Artiste University's faculty team. Dr. Silverfish, not surprisingly, was head of the Psychological Arts Department, and lead the checker team. She often boasted about how she could have been a top pro player, "but I have a Ph.D., you know, and it's really my duty to teach the next generation of students."
"Ph.D., Schmee-h D.," Marvin had remarked, with characteristic impoliteness, when the local press asked him what he thought about his opponent, "You still got to make the right moves to win the game." At that point Marvin excused himself and went off to find himself a beer, which in San Diego wasn't particularly difficult.
But once again, Marvin had found himself not just a beer, but a few beers, and so at the start of the match he was, shall we say, at less than a hundred percent, and Dr. Silverfish was not one to fail to exploit a weakness.
"Who you starin' at, Silverfish?" said Marvin in his most irritating tone. "We'll see who's going to die, you old bookworm!"
Dr. Silverfish cleared her throat. "I don't respond to comments by inebriated louts," she said. "I just crush them, like this."
To Marvin's amazement, Dr. Silverfish picked up the empty soda can sitting at her left and, with one hand, squeezed it until it split along the seams.
Marvin repressed a shiver, hoping Dr. Silverfish hadn't seen. But she didn't miss much.
"You should be scared, maggot," she said, but before she could go on, the referee blew his whistle, signalling the start of the match. Marvin lead off with the Black pieces, and Dr. Silverfish had the White.
"Your tricks don't fool me," Dr. Silverfish said. "I know a poor move when I see one."
"Drinking doesn't help you play better, little man."
(This is the end of of the KingsRow opening book. White has an advantage due to the odd line played by Black.)
(Good, but 32-27 would have been really strong here; White still has a definite edge.)
(30-25 would have been hard to draw against. White now has just a narrow advantage.)
(10-14 loses after 28-24.)
(A poor move allowing only the narrowest of draws. 4-8 was correct.)
Dr. Silverfish smiled. "Your poor play continues," she said, "and now I will finish you off."
Indeed, Marvin was fidgeting in his chair, as he always did when he was in a tough spot.
(32-27 would have kept the lead. The game is now even.)
Marvin exhaled. "Well, there, Silverfish, you ain't as good as you think you are. You missed your chance and you ain't getting another, not against ole Marvin."
How will Marvin save the game? Can you stand up to Dr. Silverfish's terrifying stare and find the solution? Don't panic; work it out and then click on Read More to see the solution and the conclusion of our story.[Read More]
"Natural" moves. "Familiar" positions. Expert players understand these concepts and apply them to great effect. But powerful computer engines sometimes turn these ideas on their heads. While the human expert relies on a combination of analysis and the application of principles, computer engines can analyze very deeply and find unexpected things. This is sometimes called "concrete" analysis, and it's changed the world of chess as well as the world of checkers.
Today we'd like to present a small investigation into the Double Corner opening, looking at a move that's sometimes taken, even if it's not so good. Here's the play.
This move is seen from time to time in amateur games. It is decidedly inferior to the preferred 25-22, but is it a probable loss? Maybe. Let's see how the KingsRow computer engine projects subsequent play.
The critical point. Here the computer chooses the "unnatural" 21-17, pitching a man and accepting a loss in the interest of prolonging play, as the computer will often do. But what if White tries to hold things together with 22-17 as listed above?
White continues to try to save a man but is now hopelessly lost.
The rest is really pretty easy, and we're sure you'll figure it out. Have your say, then see what the computer says by clicking on Read More.[Read More]
