An Introduction to Chess: More notes on notation – Stabroek News

This week we return to notation to allow readers a better understanding of how the pieces move and capture, how to react when the King is in check and how to bring a chess game to its conclusion. The best way to do this is by going through the motions of solving the puzzle.

The aim of chess is not to swap pieces. Rather, it is to checkmate the King. The King cannot be removed from the chess board during a practical game. Every other piece or pawn can be captured and removed. Checkmating the King means placing the King in a hopeless position. The word checkmate is also used in situations pertaining to life. In chess, checkmate is when the King is unable to escape, similarly in life.

When check is announced, you have to leave everything you are doing and attend to it. You can block a check, move your King out of check, or capture the piece that is announcing the check. The goal of all chess puzzles is to checkmate your opponents King no matter what moves he makes. You have to administer checkmate in the required number of moves.

Some chess puzzles are created from actual chess games and some are chess compositions. I prefer the ones from actual games. In some compositions, we can reach a position that cannot be reached in a chess game. Chess puzzles are automatically verified so that the solutions are correct and complete. Sometimes a shorter solution to a puzzle exists.

My chess colleague Loris Nathoo has the rare ability of finding a shorter solution to a puzzle. He works on the puzzle on Sundays and presents me with the solutions. The two puzzles in Diagram 1 and Diagram 2 are taken from actual grandmaster games.

In Diagram 1, it is Black, played by Vitaly Chekhover, to play and win. The game was played at Leningrad in 1934. Black plays Re1+ (+ is an abbreviation for check). The Rook goes down on the back rank and calls check. White has to attend to this check immediately. He cannot take the Rook with his Rook which is stationed at d1 because White will lose his Queen with check. So White is forced to play Kf2. Black plays Re2+. White cannot capture the black Rook since it is protected by the black Queen. White is forced to retreat to f1 or g1. When he does, the black Queen will take the g pawn and it is checkmate since the white King cannot evade the check.

In Diagram 2 Vishy Anand is playing the black pieces. The game was contested at Salonika in 1984. It is Black to play and win. Black plays Ra1 if Rxa1 (x means capture) Nf2+. To prevent checkmate, White has to capture the Knight with his Queen which gives black a decisive advantage.

Chess: national solving championship opens for entries from Britain this week – The Guardian

This weeks puzzle is the opening round of a national contest where Guardian readers traditionally perform strongly. You have to work out how White, playing, as usual, up the board in the diagram, can force checkmate in two moves, however Black defends.

The puzzle is the first stage of the annual Winton British Solving Championship, organised by the British Chess Problem Society. This competition is open only to British residents and entry is free. The prize fund is expected to be at least 1200, plus awards to juniors.

If you would like to take part, simply send Whites first move to Nigel Dennis, Boundary House, 230 Greys Road, Henley-on-Thames, Oxon, RG9 1QY. Or by email to winton@theproblemist.org.

Include your name, home address and postcode and mark your entry Guardian. If you were under 18 on 31 August 2019, please include your date of birth.

The closing date is 31 July. After that, all solvers will receive the answer and those who get it right will also be sent a postal round of eight problems, with plenty of time for solving.

The best 20-25 entries from the postal round, plus the best juniors, will be invited to the championship final in February (subject to Covid-19 restrictions). The winner there will qualify for the Great Britain team in the 2021 world solving championship, an event where GB is often a medal contender.

The starter problem, with most of the pieces in the lower half of the board, is tricky and with an unusual twist. Obvious checks and captures rarely work. It is easy to make an error, so review your answer before sending it. Good luck to all Guardian entrants.

Magnus Carlsen survived some anxious moments this week in his quarter-final match in the online Clutch International before the world champion overcame Americas top junior Jeffery Xiong. The 19-year-old Texan had a purple period in the middle of the 12-game series when he had a run of five games with two wins and three draws.

Carlsen was dominant at the start and the finish and his best two victories were imaginative attacks where the rare knight move Nh7! featured.

The event, financed by the St Louis billionaire Rex Sinquefield who has made his home city a global chess centre, has the highest prize fund yet, $265,000 (approx 207,000), for an internet tournament.

Carlsen controlled the first session of his semi-final on Thursday evening as he led Armenias Levon Aronian 6-2 without losing a game. Wesley So also led 6-2 in the all-American semi-final against the world No 2, Fabiano Caruana.

A Carlsen v So final would be far from a done deal for the world champion, as So is currently in excellent form. The semi-final is also not over yet due to the Clutch scoring system where the final two games (of six) count double on the first day and triple on the second. In his interview after the Thursday session, Aronian declared his intention to go into berserk mode for the last six games, taking extra risks to get back into the match.

Both semi-finals can be viewed live online for free with grandmaster commentary, starting at 7pm on Friday.

Karjakin vs. Cosmonauts | Earth vs. Space 50th anniversary chess game – chess24

Russian Grandmaster Sergey Karjakin played a game ofchess against cosmonauts Anatoly Ivanishin and Ivan Vagner on Tuesday 9th Juneto celebrate the 50th anniversary of the 1st ever Space-Earth game. Thecosmonauts were 400 km above the Earth on the International Space Station, which recently welcomed NASAastronauts Bob Behnken and Doug Hurley and their SpaceX spacecraft, whileSergey played from the Moscow Museum of Cosmonautics, exactly 50 years afterthe first game was played in 1970.

The game was organised by the Moscow Museum ofCosmonautics, the Russian space agency Roscosmos and the Russian ChessFederation and broadcast live from 11:00 CEST, in English.

And in Russian:

The game ended in a fast and sharp draw, where almost all of the moves were perfectly played:

1. e4 e5 2. f3 c6 3. b5 a6 4. xc6 dxc6 5. O-O e6 6. b3 c5 7. xe5 d4 8. c4 xc4 9. bxc4 xa1 10. c3 b5 11. h5 f6 12. f3 b4 13. e5 O-O-O 14. a3 xf1+ 15. xf1 bxc3 16. exf6 cxd2 17. a8+ d7 18. d5+ c8 19. a8+ d7 20. d5+ e8 21. e4+ d7

1/2-1/2

2016 World Championship Challenger Sergey Karjakin needs nointroduction on a chess website. Cosmonauts Anatoly Ivanishin and Ivan Vagnerhave been on the International Space Station since April 9th, when they arrivedtogether with NASA astronaut Christopher Cassidy.

They were recently joined by astronauts Douglas Hurley andRobert Behnken, whose SpaceX vehicle was the first to be launched from US soilsince the last flight of the Space Shuttle in 2011 and the first ever crewed commercial orbiting spacecraft. NASA estimated 10 million people watched the launch, with their arrival on the ISS also streamed across the world:

There are few details about the game to be played againstSergey Karjakin, except that Space plays White, but its value is symbolic, marking 50 years since thefirst such game.

Cosmonauts Andrian Nikolayev (1929-2004) and VitalySevastyanov (1935-2010) were the first humans to spend two weeks in space (NeilArmstrongs Apollo 11 flight to the moon and back a year earlier took just over8 days), with their Soyuz 9 flight ultimately lasting almost 18 days, orexactly 424 hours of weightlessness, as recorded on commemorative stamps.

The mission was in preparation for the Soviet Unions earlyspace station, with Vitaly Sevastyanov in 1986 telling the Russianchess journal 64:

When Nikolaev and I were preparing for our flight they toldus: Youre going to be flying for a long time. You need to think of how to meaningfullyspend your rest time during the hard work of the flight. What do you want totake onto the spaceship? Andrian and I were great chess enthusiasts and answered together: Chess! Unexpectedly the psychologists were wary. There are two ofyou on the flight. Itll turn out that one of you always beats the other and therecan be unnecessary negative emotions for the loser. Thats no good. Come on,we objected with one voice. On earth we play at the same level. Why should one of us always win in Space?

The psychologists gave in and chess went into space, thoughit was a special chess set designed for zero gravity by a young engineer calledMikhail Klevtsov. Magnets werent allowed (and still arent today on the ISS)due to their potential to interfere with instruments, and the pieces wereinstead kept in place but movable by a series of grooves, so they didntaccidentally fly into the mouth of a sleeping cosmonaut (Sevastyanov).

The players on the ground were General Nikolai Kamanin(1908-1982), the head of the cosmonaut training program, and cosmonaut ViktorGorbatko (1934-2017), with another cosmonaut, Valery Bykovsky (1934-2019) hostingthe broadcast:

The game lasted 6 hours, or 4 orbits of the Earth, with theplayers only able to transmit their moves while the spaceship was above theSoviet Union. You can catch some glimpses of the game in this video focussed onVitaly Sevastyanov:

The game ended in a draw, which you can replay below:

1. d4 d5 2. c4 dxc4 3. e3 e5 4. xc4 exd4 5. exd4 c6 6. e3 d6 7. c3 f6 8. f3 O-O 9. O-O g4 10. h3 f5 11. h4 d7 12. f3 e7 13. g4 g6 14. ae1 h8 15. g5 eg8 16. g2 ae8 17. e3 b4 18. a3 xc3 19. bxc3 e4 20. g3 c6 21. f3 d5 22. d3 b5 23. h4 g6 24. f4 c4 25. xc4 bxc4 26. d2 xe1 27. xe1 d5 28. g5 d6 29. xd5 cxd5 30. f4 d8 31. e5+ f6 32. gxf6 xf6 33. xf6+ xf6 34. e8+ xe8 35. xf6+ g81/2-1/2

Space missed the best chance to conquer the Earth on move23:

23.g5! wins a piece, since the only move for the knight is23Nh5, but then 24.Qg4! forces 24Qxg4 25.hxg4 and after the again forced 25Ng326.Rf2 there are various ways for White to pick up the trapped knight.

One of the most interesting things about the game is that itwas commentated on widely by the best Soviet chess players. David Bronsteinwrote in the Izvestia newspaper:

That game will undoubtedly go down in the annals of the 1000year long history of chess as the game that spread the sphere of influence ofthis wise game beyond our planet. Everyone can understand the emotion withwhich I look over the moves sent from space. The first Space Earth game isvery interesting to play over on a board. From the moves its easy to see thatboth sides love sharp, puzzling situations and show no lack of courage andinvention in creating them. And the fact that neither side managed to win bearswitness to the skill of the players not only in attack but also in defence.

Later that year on the 24th November 1970 the cosmonautsvisited Moscows Central Chess Club for an evening featuring World ChampionBoris Spassky, former World Champions Mikhail Botvinnik and Tigran Petrosian aswell as other top players.

It was right in the middle of the Palma deMallorca Interzonal that would mark a sea change in chess, with Bobby Fischer going on to win by a huge 3.5 point margin. Of the six players who qualified for WorldChampionship Candidates Matches only Efim Geller and Mark Taimanov representedthe USSR, with Fischer, Bent Larsen, Robert Huebner and Wolfgang Uhlmann taking the remaining places. Alexander Kotov, best known now for his Think Like a Grandmaster book,referred to that as he tried to look 40 years ahead, i.e. to 2010, that evening:

Im sure that then well have not an Interzonal but an InterplanetaryTournament. And the grey-haired, now ex-World Champion, Boris Spassky, will comeout with a big article where as a journalist hell criticise the organisers thatfor some reason they allocated two places to weak players from Jupiter,reducing by two the representation of the lunar base And chess fans, gatheringin an even more luxurious club to assess the outcome of the Interplanetary Tournamentwill of course recall the first game played in space that opened a new era forthe ancient game.

Back then it was hard to imagine that the last men to travelto the Moon would have done so just two years later in 1972, with no Sovietcosmonaut ever standing on the Moon.

3-time World Chess Champion MikhailBotvinnik also referred to the Interzonal Tournament while talking about thehead of the cosmonaut training program:

36 years ago I saw Nikolai Petrovich Kamanin for the firsttime, if Im not mistaken, in the Grand Peterhof Palace not far from Leningrad,when the ChelyuskinHeroes were being honoured there. Back then we were both very young andboth could have become cosmonauts. Now, of course, Im no longer fit for that.

I look on General Kamanin with great envy. Although werethe same age hes taken great care of himself and is in charge of ourcosmonauts. Besides that, Ive already stopped playing chess myself, whileKamanin, as we just got to see, still continues to perform well in events.

From the stories of Andrian Nikolaev and Vitaly Sevastyanovit became clear to us what difficulties a man faces in space. The first isphysical weightlessness, which can be compared to what the participants in theInterzonal Tournament in Palma de Mallorca feel, when theres only a rest dayonce in every 9 days. The second difficulty is, if we can put it like this,intellectual weightlessness.

When a man finds himself on the Earth in everyday life hesconstantly confronted by the solution of complex problems or, to put it anotherway, inexact problems. Its not so simple to cross a street, to decide how tospend an evening to go to the cinema, theatre or find a more frivolousactivity. But on a spaceship a man has none of that and he can forget how tosolve complex, inexact problems. And here chess comes to the rescue becausechess is a typical complex, inexact problem. After all, its long been knownthat people playing chess drift and find the correct decisions withdifficulty.

I by no means want to suggest that cosmonauts should bepicked from among chess players. On the contrary, I think that if ourgrandmasters will play the way theyve played at the start of the InterzonalTournament in Palma de Mallorca (not counting, of course, Geller), then wellneed to find chess reserves from among the cosmonauts

Of course since 1970 chess has been played in space, with someastronauts having had plenty of time as they spent hundreds of days on Mir and now the International SpaceStation. The US Chess Federation in particular organised anEarthvs. Space matchgiving the chance for kids to take on astronauts. Chess always makes for good photo opportunities!

Tuesday's game will be a memorablecelebration of some of the early pioneers of space flight.

GMs Pravin Thipsay, Vidit Gujrathi launch Maharashtra Chess Associations official website – The Bridge

Grandmasters Pravin Mahadeo Thipsay and Vidit Gujrathi, on Saturday, launched the official website of Maharashtra Chess Association (MCA), the official chess body of All India Chess Federation (AICF) for Maharashtra.

The website has been launched by MCA to bring Chess enthusiasts across the country closer on a digital platform, in the wake of the global coronavirus pandemic. On the website one can not only find all relative information about MCA, the office bearers, registration procedure, future initiatives but also interact and play the game.

The MCA has sprung into action ever since the AICF restored their affiliation after a protracted legal dispute was resolved. The dispute had originally stemmed from a factional tussle within the MCA, which was registered as a society in 1975, by amalgamation of the then five regional chess bodies in the state. The association was then granted affiliation by the AICF in 1978.

In 2012, the AICF asked all its affiliates to amend bye laws to adapt with the one nation, one federation norm. But the tussle within MCA factions, however, resulted in delay of the completion of the entire process. In December 2016, the AICF disaffiliated the MCA for not amending their bye laws in time.

Finally, in April this year, in a Special General Body Meeting (SGM), a five-member panel decided to restore the affiliation of MCA along with Rajasthan Chess Association. Earlier this month, the Pune-based chess body hosted a unique Blitz Grand Prix tournament, brought by LetsUp.

The Blitz tournaments, which have a total prize fund of INR 155000, are being held every Wednesday from June 3 to July 1. Each tournament has a total prize fund of INR 25000 and top five GP finishers get a total of INR 30000. The event has been sponsored by Nasik District and Novel, Ahmednagar District and Narendra Firodia Unicorp, Pune District and Amanora, Jalgaon District and Jain Irrigation and h2e, and lastly, the Sangali District and Chitale Bandhu.

Charity Event Raises Over $7,500 For West Bengal, India – Chess.com

An Indian charity tournament held June 4-7 on Chess.com raised just over$7500 for the state of West Bengal, India, which was paralyzed by the Cyclone Amphan a couple of weeks ago. This event was a joint effort by Chess.com and Samay Raina, one of India's leading stand-up comedians.

The tournament was held in four categories on the Chess.com live server and was broadcast live on Raina's YouTube channel and on ChessTV. More than 2,000 users played across four days making this event a great success.

Guest appearances during the live show included GM Vidit Gujrathi, GM Adhiban Baskaran, Tanmay Bhat, Biswa Kalyan Rath, Raftaar, Abhishek Upmanyu, WFM Alexandra Botez, Vaibhav Sethia, and many more. The commentators included Samay Raina (host), IM Sagar Shah, and IM Rakesh Kulkarni (yours truly).

Here's the full show from day two for replay:

To participate in the event, users had to donate a minimum of $1.50 (INR 110 approx). A player could play on all four event days if their rating allowed. The rating groups were divided into four categories: 0-800, 0-1400, 0-1800 and one open to everyone on the final day.

There was an overwhelming response by Chess.com users throughout the globe with more than 2,000 players taking part across four days. On each event day, the players played a three-hour arena. Then, the top-four headed for a knockout to determine the top-four standings. The top four of every event won diamond memberships in prizes.

More importantly, $7,500 was collected by Chess.com donations and some more via other platforms and raised for the people affected by the Cyclone Amphan in West Bengal.

"I'm delighted with the response from the users and appreciate their generous contribution. I also hope they enjoyed playing it," said Raina, the instigator behind the event."Raising money was our main intention but it was great to see everyone come together and play for a noble cause. I hope they enjoyed it as much as I did."
