Solution to Puzzle 431. Qe6#This chess puzzle shows a position in the opening phase of a game. In the opening, the position of the king must be defended. See and compare the position of the White king and that of Black. The White king is secured and the Black king exposed… The Black king moved ahead and is blocked by 3 his pieces behind him… The White queen moves on e6, which is defended by the White bishop, to mate in one. The mated king is not secured; he is ahead and blocked by his 3 pieces behind – the queen-bishop mate delivered.Back to top

Solution to Puzzle 441. Qh8#This chess puzzle shows a position in the endgame phase of a game with a fierce open fight. Have a look at the position around the Black king. The Black king is close to a corner; the f7-square (the key square in this position) is blocked by a friendly pawn… The White knight is attacking the corner square on h8. This is a typical position to engage the queen-knight mate. The White queen moves on h8, which is defended by the White knight, to mate in one.

Why the world’s toughest maths problems are much harder than a chess puzzle, and well worth US$1m – The Conversation UK

The above picture shows a chessboard with two queens placed on it. As the queens do not share the same row, column or diagonal of the chessboard they are not attacking each other. Can you place another six queens on the board so that none of the eight queens are attacking each other? And if its possible, how many ways are there to do it?

This illustrated puzzle using a typical chessboard, an example of what is called the 8-queens completion problem, is from 1850. Yet only now, in a paper written by Chris Jefferson, Peter Nightingale and me published in the Journal of Artificial Intelligence Research, have we confirmed the depth of complexity hidden within the puzzle when scaled up to allow for boards of any size, with any number of queens pre-placed in any arrangement on the board a much harder version of the puzzle known as n-queens completion.

Unfortunately, due to misunderstandings when our paper was reported by the media (here for example, or here with correction) many people now think I am going to pay them US$1m. I am sorry to disappoint them, and hope here to put the record straight.

The n-queens completion puzzle is a form of mathematical problem common in computer science and described as NP-complete. These are interesting problems because if an efficient solution can be found for one NP-complete problem, it can be used to solve all NP-complete problems.

Some of these puzzles may seem unimportant identifying the largest number of Facebook friends that dont know each other, for example. But a fast and efficient solution to this problem could also be used to solve other problems with a more practical purpose for example, calculating the password used to encrypt data sent between a web browser and a bank. While it may seem odd that the placement of queens on a chessboard can in some way be translated to password encryption, that is indeed the case. That is the nature of all NP-complete problems.

Thousands of problems have been proved to be NP-complete. What I like about n-queens completion is that it is one of the simplest NP-complete problems to explain, especially to people who know the rules of chess. It is also a simple variant of one of the most widely studied problems in artificial intelligence: n-queens, which is the same puzzle but starting with an empty board rather than one with pre-placed queens. Following our paper, we now understand that the reason why the n-queens completion problem is so much harder than the version with an empty board is that it is an example of an NP-complete problem.

Nobody knows, even very roughly, how hard NP-complete problems are. They could be as easy as sorting a list of names into alphabetical order, or they could be exponentially harder. Finding out which they are is called the P vs NP problem, and it is one of the great unsolved mathematical problems so much so that the Clay Mathematics Institute (not me) is offering a prize of US$1m for the solution of P vs NP.

Since our paper shows that the n-queens completion problem is NP-complete, anyone able to show whether its an easy or difficult problem could win a million dollars. This seemed an obvious hook to publicise our paper, and while we were delighted to take part with Peter and I posing with giant chess pieces we only wish that the reporting hadnt given people the impression they could win the money for solving the n-queens problem, rather than the P vs NP problem that is far harder and potentially unsolveable.

Its possible the reason people misunderstood what was required to win the Clay Institutes prize is how many layers removed the prize requirements is from solving chess puzzles.

First, they needed to be tackling the right problem, since n-queens is easy and n-queens completion is hard.

Second, it is not enough to solve instances on a standard 8-by-8 chessboard. For example, we already know that the 8-queens completion problem from 1850 has two possible answers. People have to solve the problem for any sized chessboard.

The third layer is to solve the puzzle not just for a particular layout of queens, but for any possible layout of any possible number of queens on a board of any possible size. Even finding algorithms for this level of n-queens completion is not enough.

The fourth layer is to not just solve the puzzle, but to mathematically prove the properties of the algorithms that have given you the answer. This is where the prize money is: to solve the wider P vs NP question, one must either mathematically prove that an algorithm exists that can solve n-queens completion efficiently (technically, in polynomial time) or alternatively to mathematically prove that this is impossible. And, in either case, to have published this work in journals for the worlds mathematicians to pore over for two years.

Its possible that we hadnt made clear the sheer complexity of the task required to win the prize money. It might be said that we failed to explain these layers very well. If I may help those still aiming for the prize, however, I would advise the following:

Get a PhD in computational complexity

Be brilliant

Be very, very, lucky

Can You Solve the Million-Dollar, Unsolvable Chess Problem? – Atlas Obscura

The problem may not be intrinsically challenging by nature, but increasing the size of the board pushes it from complex to nigh impossible. Public Domain

Faced with seemingly unsolvable problems, historically, people get creative, whether a sword through the Gordian Knot or the threat of one through a disputed baby. But a seemingly simple chess problem will require a sharper solutionso sharp, in fact, that researchers at the University of St. Andrews in Scotland are offering a $1 million reward.

The riddle, known as the Queens Puzzle, was devised in 1850. Eight queens must be placed on a standard chessboard so that no two pieces can take one another. According to a release from the university, This means putting one queen each row, so that no two queens are in the same column, and no two queens in the same diagonal. Solutions are not hard to imagine, but the problem becomes more complex when the chessboard growssay 100 queens on a 100-by-100 chessboard. When the numbers start getting really large, computer solutions are unable to solve it.

Any program that could do so will be far more powerful than anything we currently have, said Professor Ian Gent, a computer scientist at the university. If you could write a computer program that could solve the problem really fast, you could adapt it to solve many of the most important problems that affect us all daily. This program, he said, would be able to decrypt even the toughest online security, something that would take current software thousands of years to unravel, by scrolling through and then discarding an almost infinite number of solutions until one works. His colleague, Peter Nightingale, questioned whether this is even be possible. What our research has shown is thatfor all practical purposesit cant be done, he says. Hence the massive prize offer.

Although its hard to prove definitively, historians believe chess was invented in around the year 570, in what is now northeastern India. There is no shortage of famous chess puzzles, many of which remain unsolved to this day. A more recent development, however, has come in the writing of programs that create or solve problems too difficult or time-consuming for humans to do unassisted.

Some of these programs are so complicated that even their designers dont fully understand how they work. Chesthetica, a program written by the computer scientist Azlan Iqbal, generates hundreds of problems, using digital synaptic neural substrate (DSNS) technology. One might ask where does Chesthetica get its ideas? writes Iqbal in Chess News. I do not know. How or why should a computer be able to compose chess problems like these at all? Can computers autonomously do this sort of thing? These are also good questions and I believe the answer lies with the DSNS technology. Why it works, he explained, remained an open questionbut, somehow, it does. Maybe the large Queens puzzlesolving program will be similarly inscrutable.

Young Marape shines in Zimbabwe – Mmegi Online

Marape (10) proved her mettle when she took part in a competition above her age category. She played in the Under-13 category and still proved too strong for her senior counterparts, bagging a gold medal.

Her performance meant she booked her space at the World Schools Individual Championships to be held in Durres, Albania in April 2018. Marape has also qualified to receive a higher international chess title, Woman FIDE Master.

Her coach and father, Marape Marape told Mmegi Sport yesterday that almost every player in the category was three years older than Naledi.

She has been the most consistent national youth player over the past three years. She is the fulcrum of the team and the only player to have won a medal at each of the past three African chess championships, he said.

Naledi was part of the team that was in a training camp with the Russian Grandmaster Nickolay Chadaey for three weeks before the competition in Harare.

The coach said the camp assisted the player a lot. He said in addition he made sure that everyday for four weeks prior to the Africa Schools Chess Championship, she had a daily schedule that included studying chess tactics, solving chess puzzles, end games, openings and middle game theory.

I made sure that

she fulfilled this schedule. Also as part of preparation for this tournament, I took her to Durban to take part in the South Africa Open Chess Championship in July. That tough tournament gave her the necessary practice, he said.

He said the time controls of South Africa Open Chess Championship and Africa Schools Chess Championship were the same but the standard of competition was different. He said despite the tough competition she faced in Durban, she brought home a medal.

Meanwhile, Botswana emerged as the champions of Africa Schools Chess Championship after collecting nine medals (three gold, three silver and three bronze). The hosts, Zimbabwe finished in the second spot with 10 medals (two gold, four silver and four bronze). Uganda anchored the log with two medals (one silver and one bronze). Other countries that competed at the championship are Kenya, Angola, Zambia and South Africa. Botswana Chess Federation spokesperson, Kutlwano Tatolo said the team was under the guidance of Chadaev. Botswana defended their title won last year.

Gold medals: Natalie Banda (Under 11 girls) and Temo Kapane (Under seven boys)

Silver medals: Susan Sethebe (Under-17 girls), Laone Moshoboro (Under-9 girls) and Hasitha Manikonda (Under-7 girls)

Bronze: Thabo Elias (Under-17 boys), Marape Marape Junior (Under-15 boys) and Arona Moshoboro (Under-11 girls).

Small-Business Success Story: Learners Chess Academy – Kiplinger Personal Finance

His nonprofit uses chess to help kids succeed in and out of school.

Victor Francisco Lopez, founder and executive director of Learners Chess Academy Photo by Minseh Barcrania

By Pat Mertz Esswein, Associate Editor From Kiplinger’s Personal Finance, September 2017

Kiplinger’s spoke with Victor Francisco Lopez, 31, founder and executive director of Learners Chess Academy, an Albuquerque, N.M.-based educational program that aims to enhance child development through playing the game of chess. Here, he discusses what motivated him to start the program and more. Read on for an excerpt from our interview:

What’s your mission? We use chess to teach kids intellectual, social and leadership skills in school clubs and camps. The game is the medium, not the ultimate goal. The kids learn the rules, moves and tactics; practice analytical skills; and play chess puzzles and mazes. They practice mindfulness — sitting and breathing — to calm down and resume their decision-making after they lose a piece or make a bad move. They learn not to brag or talk too much while playing, as well as to respect their opponents. Many older players become junior leaders and teach newer players.

How did you learn to play chess? I learned from my dad when I was 5. In sixth grade, I joined a chess club at school. I loved it, and I noticed that as my game improved, so did my grades, and school became easier. I started a chess club at my sister’s school and ran it until I graduated from high school. Im a Class B player, meaning I’m in the 90th percentile of U.S. amateur players.

Why did you start Learners? After college, I came home to start a micro-lending nonprofit while I went to business school and worked as a substitute teacher. One school asked me to coach its chess club. I thought, I forgot how really fun this is! Teachers told me, “You’re literally coaching the kids to think.” So in 2010, I started a summer camp, and the next summer I began pursuing Learners full-time.

How did you launch it? I borrowed $2,000 from my mom to print fliers, and I either cold-called school principals or took substitute-teaching jobs to develop relationships. I hired coaches who play chess, believe in our mission and are good with kids. Kids love our program, so we’ve grown through strong word of mouth, too.

Learners is a nonprofit? I started it as a sole proprietorship. But in 2012, I registered it with the IRS as a 501(c)3 nonprofit so I could gain access to more venues and raise more money for a need-based scholarship fund. The club costs $75 to $100 per semester, and the camps cost $150 per week of half days or $250 for full days. We offer need-based scholarships for 25% to 95% of the cost. We reinvest our profit into programs in low-income areas. I take a salary.

How big is Learners? In the 201617 school year, we reached about 1,700 children in chess clubs at 51 schools and chess camps over 11 weeks. So far, weve taught 7,055 children and awarded more than $72,000 in scholarships.

What’s your greatest challenge? How we continue to grow and raise money to give more scholarships without losing the heart of who we are. Right now, we’re doing exactly what we want to do without changing to meet, say, a foundation’s requirements.

What’s your greatest satisfaction? Seeing kids I taught become leaders and coaches. In the summer of 2016, two of our high school leaders spent 10 days teaching chess to 36 kids in a rural village in El Salvador. I was in tears almost every day watching them teach in the middle of the jungle.

Feature story: Lauren Goodkind plays, teaches and writes about chess – The Almanac Online

While her last name may reflect noble human qualities, when it comes to playing chess, Menlo Park resident Lauren Goodkind can leave those attributes — certainly the “kind” one — at the door.

“On the chessboard, I would say I’m a mean kind of person,” she said, smiling, in a recent interview. “I’m a competitive person. It feels really good to win, so I can be mean on the chessboard. … If you’re playing chess, you’ve got to be mean, if you want to win.”

A French proverb offers these words for the kindhearted: “You cannot play at chess if you are kindhearted.” Another French source, painter, sculptor and chess player Marcel Duchamp, described chess as “the movement of pieces eating one another.”

OK, so you probably have to be mean. Ms. Goodkind, 33, apparently has what it takes, with 15 years of playing behind her and a current rating of Class A from the U.S. Chess Federation. She’s one category away from being rated an expert.

When she plays, her opponents are usually men or boys.

She says she once played entrepreneur and venture capitalist Peter Thiel. At the time, he was in his mid-30s and enjoyed a chess-master rating while Ms. Goodkind was just a year out of Woodside High School and rated well below Mr. Thiel. Ms. Goodkind says she played him to a draw. “Oh, it was exciting to draw against Peter,” she says.

(Mr. Thiel has not responded to requests for comment.)

Occasionally she’ll run into a bad apple, like the time she beat an older man in Burlingame whose skill level was one rating above hers. He began swearing at her after she won, she says. “Really bad sportsmanship.”

She’s been teaching chess to Peninsula residents of all ages for about four years and is the author of the recently self-published “50 Poison Pieces,” a 217-page book of 50 chess puzzles. Each puzzle asks the beginning player to analyze a situation in which capturing a vulnerable piece is a mistake, and often a costly mistake.

“One silly move can cost you the entire game,” she says.

Chess was relief

In high school, chess served Ms. Goodkind as an escape. The arc of her life before ninth grade included working with a speech coach and spending time in special-education classes, she says. In high school, she says she was bullied because of the way she talked.

With a C+ grade point average and unable to concentrate on her schoolwork because of the bullying, Ms. Goodkind says she had no interest in taking advanced-standing or advanced-placement classes. “I didn’t really care,” she says. “My classmates were really mean to me.”

The weekly chess club offered her a way past the misery. “Chess helped me get through high school. It felt good to win and I felt happy beating other people,” she says. “Everybody is smart in their own way.”

She graduated in 2002 and went on to earn a bachelor’s degree in communications from Notre Dame de Namur University in Belmont.

Women and chess

Playing other women is something she especially appreciates, but it doesn’t happen often. “I hope to see more women and girls playing chess,” she says.

Most of the top players in competitive chess are men. At tournaments, she says, the number of women players is usually less than 2 percent.

“A woman can beat any man,” says Alexandra Kosteniuk, a Russian grandmaster and author of “Diary of a Chess Queen,” published in 2010 by Mongoose Press.

Ms. Kosteniuk says the challenges of attracting women and girls to chess are like the challenges in other areas, including physics, math and being an astronaut. The key, she says in a 2016 interview at the World Chess Hall of Fame in Saint Louis, Missouri, is creating more chess clubs that are friendly to girls and more programs to support them.

Asked about women mixing it up with men in a milieu in which men outnumber women, Ms. Goodkind had a simple reply: “Women are strong. We can play chess, too.”

Judit Sztaray is the executive director of the nonprofit, BayAreaChess Inc., and the mother of three chess-playing girls. At BayAreaChess, she is organizing girls-only events to give them a better chance of winning titles.

She says she sees no differences between girls and boys in their ability to play. “The value of learning chess is universal,” she says, “especially among the young in that their brains and capabilities are still developing.”

Resistance from men to the idea of playing against women is “very, very rare,” she says, though boys do tend to tease girls about it. “I have to say that generally kids who are playing chess are the more civilized people,” she says.

Chess is a civilized game then? She laughed. “Depends on who you ask,” she says. “Mentally, it is a brutal game. It’s win or lose.”

Avoid silly moves

Skilled chess players typically think two or three or four moves ahead, which takes practice. A lot of practice. With her puzzles, Ms. Goodkind gets the readers on the road by asking that they think just one move ahead. And avoid moving without thinking.

An inner Q-and-A about upcoming moves for you and your opponent, and whether they can succeed, should become second nature, she says.

“You have to focus,” she says. “That’s the key to playing chess.”

Solve Puzzles (And Sometimes Crime) In Picross Dating Sim – Kotaku

Picross Makeout League tests your love of picross through puzzle-themed dates.

Picross Makeout League is a short visual novel about a group of superheroes called the Puzzle League, who are all themed after various kinds of puzzles. You play as Picross Girl, whose superpower is to be really good at picross, a puzzle in which you follow a numbered guide to make rudimentary pictures on a grid. Picross Girl sees picross puzzles everywhere, and you, the player, are tasked with solving them. Her teammates are basically the personification of different kinds of puzzles: Crossword is constantly giving you crossword clues, Chess is obsessed with black and white thinking, Piecea is an actual puzzle piece, and Sudoku is pretty unforgiving. The plot is not fully developed in this demo, leaving you on a cliffhanger as Picross Girl is kidnapped, but you do get to go on dates with some of your teammates.

While it might sound boring at face value, Picross Makeout League is an unexpectedly funny affair. Heres the very first puzzle you solve, based on what Picross Girl sees as she is kidnapped and blindfolded:

After being introduced to the team, the player selects a character for Picross Girl to go on a date with. Only your teammates Crossword and Chess have full dates in this version of the game, but the whole cast has distinct personalities, and youll get a chance to spend some time with each of them. While I wish I could have dated Piecea, the anthropomorphized puzzle piece, I did love my date with Chess, who ranted and raved about conspiracy theories and chess puzzles. At one point he says that he needs to be five, ten or even 500 moves ahead of his enemy and Picross Girl asks, Can you play 500 moves ahead in chess? Her date answers, If you are both really bad, then yes.

If you dont really get or like picross puzzles, the game lets you skip through them using the fast forward button, but its more fun to play through the puzzles during your dates and elsewhere. While youre out with someone, the puzzles are all themed to the date at handChesss picross are all chess pieces, Crossword takes you to an art gallery where you solve art-themed picross. Im not very good at picross, but I was able to guess my way through the harder puzzles.

If you love picross a lot, Picross Makeout League is worth a try. Even if you dont, its funny writing makes for a good diversion. Grab it for free on itch.io.
