I’ve become a ChessCube Business Partner!

Sean

ChessCube has launched a great new service that offers you as a chess player, chess blogger, coach, retailer, club operator and so forth the ability to have their own branded chess application on their website, for free. As ChessCube’s Community Manager, I’ve been watching the project develop and grow over time, and was massively excited when the email announcing the ChessCube Business Partner offer was sent to our user base as well as external coaches. From all accounts the feedback and interest has been wonderful thus far!

Wanting a piece of the action myself, I went ahead and signed up to become a Business Partner. Setting ChessCube up on my private blog was extremely easy. Even as an end-user with fairly minimal knowledge of HTML coding, I was able to embed the website onto my own private site in less than 3 minutes. Registration with ChessCube took less than 1 minute, pasting the code given to me by ChessCube into my webpage took seconds, and uploading the new web page to my server took all of 1 minute. And that’s it, I refreshed my page, and there it was – a great chess site running on my own personal blog. Installing ChessCube vs writing a blog post on my site: Writing a blog post with Tumblr is harder, and takes longer. ChessCube makes setting their site up easy, and can be done in quicker than most can finish a blitz chess game!

FOR IMMEDIATE RELEASE

ChessCube sponsors the 2011 Online Commonwealth Chess Championships

Cape Town, South Africa – 18 February 2011

ChessCube, the world leader in online chess tournaments, with over 20,000 tournaments and 5 million games played per month, will partner with the organizers of the 2011 Commonwealth Chess Championships. ChessCube.com will run an online pre-event where three lucky winners will gain free entry, free accommodation at the venue’s Peermont Mondior hotel, as well as $1,500 in cash towards their flights and other expenses.

Graham Jurgensen, the convenor of the 2011 Commonwealth & South African Open Chess Championships, which will be held in Johannesburg South Africa from June 25th through July 3rd, said: “We are very excited to be partnering with ChessCube on this world-first online event. The real-world event will be held at the beautiful Emperors Palace Hotel Casino & Convention Resort, and the online event will give three lucky participants free entry and accommodation as well as expenses.”

The online tournament series is aimed at three groups: above 2000 players, 1700 to 2000 and below 1700 rated players. Each series will have a round robin final with eight finalists in each.

“Anyone in the world can enter the online event”, said ChessCube CEO Mark Levitt. “The Commonwealth Championships will be held in conjunction with the South African Open – and players who are not from commonwealth countries are still eligible for all cash prizes”. We are expecting a massive turnout for this online event and we would not be surprised if this breaks all known online tournament world records.”

ChessCube also sponsored the 2009 South African Open, where titled players participated from a second venue in Melbourne, Australia via www.ChessCube.com. This event made world chess history when FIDE, the world chess federation, worked with ChessCube to ensure that the Internet games, were officially rated, setting a precedent that could see tournaments using this technology in the future.

President Jacob Zuma supports South African chess

Sean

The Nkandla community in Kwazulu-Natal, South Africa, had a great day when SA President Jacob Zuma arrived to take part in a chess tournament between surrounding schools. Nonkulueko Sithole was thrilled to play President Zuma, even though the President checkmated her in fewer than 10 moves. “This is the best day of my life. I never thought I would ever sit this close to the President and play a game of chess with him,” said the 14 year old.

In an interview after the game with City Press, Zuma said, “Chess is very important as it makes you a better and knowledgeable human being. I like games like chess and bridge because they stretch your brain to the limit. They make you think strategically”. President Zuma also challenged local businesses to support the sport financially. “Next year we must host a fundraising dinner party for chess right in the hall,” he said.

Kwazulu Chess Association President Sandile Xulu, one of the tournament organisers, said chess gave “young people the opportunity to compete, regardless of race or social standing”. “It provides a field of ideas, concepts and strategy for young growing minds,” he said.  In an interview with ChessCube Community Manager, Sean, Xulu said that KwaZulu Chess’ aim is to take chess into all schools, as well as to introduce it as a sport. Future plans would then involve working with the Department of Education to consider it as a subject in school in Kwazulu-Natal and particularly rural areas and all of South Africa. “This is exactly what President Zuma and I shared and want to see happen.” said Xulu. Speaking of President Zumas’ desire to have all children take part in chess tournaments, Xulu noted, “This (the Nkandla tournament) was our “OPENING MOVE”, which we hope will get supported and start rolling”.

ChessCube supports President Zuma’s vision, and will be launching an online schools chess initiative in South Africa and other countries from early 2010. The South African government, a number of NGOs and large corporations are doing a great deal to improve Internet and computer services in schools. ChessCube will be working with all providers to ensure that schools in South Africa can connect to ChessCube’s classroom service.

“ChessCube will provide facilities for children to play chess online and to receive online video training”, explained Mark Levitt, ChessCube CEO. “The basic service will be free to all schools in South Africa, and we will be working with big business to sponsor additional opportunities for South African youth.”

ChessCube’s classroom service will be at the forefront of a modern trend to popularise chess. Along with Venezuela, which has recently included chess in it’s official school curriculum, ChessCube considers the personal and societal benefits of chess to be of immense value. What are these benefits precisely? David MacEnulty, a famed chess teacher (the subject of a movie “The Knights of the South Bronx”) had this to say in a recent exclusive interview with ChessCube:

“One of the things you learn from playing chess is how to control yourself. You learn to have delayed gratification. You learn tremendous discipline and above all you learn to trust your own judgment. Once a child learns that he or she is smart enough to play chess, there’s not going to be any holding them back from anything else.”

“The biggest benefits come when children actually sit down and play tournament chess. Once you’ve played tournament chess for a couple of years, major transformations take place in a child. The question of relying on your own judgment really comes out.”

“When the children on my chess team in the Bronx went to junior high school they were much better prepared than many of their peers. In fact, the Principal of the junior high school once told me that the chess kids seemed to be a different breed altogether. You can tell the chess kids from the way they walk down the hall – there’s just more confidence in the way they walk. There’s more confidence in the way they interact with the teachers in the classroom. They don’t get into trouble because one of things that chess teaches us is to see danger ahead of time.

“One of the things that’s overlooked frequently is the social component of being on a chess team or just learning to play chess. When children work together on a team, even though chess is one person against one person, whatever is good for anybody on the team is good for everybody on the team.”

“Now when one of the kids from a place such as where I taught in the South Bronx wins a game against a very privileged child, that changes everybody’s attitudes. The recognition, that there, on the other side of the board, is my intellectual equal, that’s an amazing transformation that happens on both sides of the board. I think that’s a really critical thing that we should introduce to society everywhere, not just South Africa.”

ChessCube Supports Chess Education in South Africa

admin

FOR IMMEDIATE RELEASE

ChessCube Supports Chess Education in South Africa

Cape Town, South Africa – 23 December 2009. ChessCube, a South African based Internet Chess Company with an 800,000 membership, offers support to President Zuma’s recent initiatives to encourage South African youth to play chess.

Playing chess at school could lead to job creation. Mark Levitt, CEO and founder of ChessCube, says, “President Zuma noted that the sport of chess develops strategic thinking for school going children. It also aids the development of mathematic and languages skills. David Macenulty, a US-based chess coach, proved that inner city New York learners who studied chess at primary school went onto tertiary education far more than their peers. So great was his contribution to chess in schools that it inspired the Ted Danson film ‘Knights of the South Bronx’.”

Levitt explains the impact of chess now on the future jobs of South Africa’s youth: “Kids who play chess at primary school level tend to go onto tertiary education to secure and create employment for themselves and others. Chess plays an important role as one of the many initiatives to create a prosperous South Africa of growth, starting with the youth.”

ChessCube is launching an online schools chess initiative in South Africa and other countries from early 2010. The South African government, a number of NGOs and large corporates are doing a great deal to improve Internet and computer services in schools. ChessCube will be working with all providers to ensure that schools in South Africa can connect to ChessCube’s classroom service.

“ChessCube will provide facilities for children to play chess online and to receive online video training”, explained Levitt. “The basic service will be free to all schools in South Africa, and we will be working with big business to sponsor additional opportunities for South African youth.”

ChessCube recently raised R10m from Invenfin, the Venture Capital subsidiary of Remgro Ltd, a listed South African Company.

Why the Internet is good for chess

admin

As the London Chess Classic prepares to get underway, there is a growing interest in Chess in the UK. A recent article in the Telegraph (read it here: London Chess Classic: the chess set come to Britain – it’s worth it) comments on the stirrings of a growing popularity of chess clubs at schools around the UK, and renewed interest in chess in the UK in general.

As Marie Gallagher comments in the article: “there is a growing recognition that chess has an invaluable role to play in education. It is a brain-accelerator, like music.”

We couldn’t agree more, and were even more pleased to read the following in the article:

“Far from killing chess, the internet has given it a shot in the arm. As a spectator sport, chess has never made great television: the time taken between moves is too long. But on the internet, with chess fans around the world able to follow a match through online forums, a slow sport has suddenly become lightning-fast, with the merits of different moves sparking feverish debate.”

This seems almost like a description of ChessCube itself, with popular short games taking place between players from around the world, complete with frequent spectators and energetic comment from the ChessCube community. Chess may be a game of war, but it’s a game that pulls people together.

ChessCube Launches Live Chess Application in Facebook

admin

Cape Town, South Africa – 24 November 2009. ChessCube, the popular live chess platform, launches a live chess application in Facebook. Facebook users can add the application to their profile, and play with Facebook friends, ChessCube friends or any player on ChessCube.

ChessCube’s live chess application allows users to connect with even more players, and play live chess from within Facebook. With about 2,000 players online at any given time, anyone will be able to find a game at the right skill level.

There are several chess playing applications on Facebook, but very few of them offer live chess. The ones that offer live chess tend to have very few players online. ChessCube offers chess players of all levels a superlative experience with about 2,000 players online and a strong chess community. ChessCube also allows games to be played between all players, no matter whether they are using the Facebook application, or the website.

Mark Levitt, ChessCube CEO says: “We are very excited to launch our first Facebook Application. Facebook is a new way for chess players to connect with the vibrant ChessCube community.”

The ChessCube chess application may be found in Facebook’s app directory, or logged-in Facebook users can go to http://apps.facebook.com/chesscube/. Existing ChessCube members can link their Facebook profile to their ChessCube profile, while new members can register with ChessCube.

ChessCube expects that this new application will add to their considerable user growth.

A commemoration of Karel Treybal

admin

First, my profound apologies for the mispelling of Radjabov’s name in last week’s blog. Note to self -  haste makes waste.

Karel Treybal, http://www.executedtoday.com/2009/10/02/1941-karel-treybal-grand-master/

On October 2, 1941, the Czech player and grandmaster Karel Treybal was shot in occupied Czechoslovakia as a suspected subversive for illegally stockpiling weapons. Considered one of the great Czech players from the turn of the century, he was executed by German occupation forces.

In the game below, Treybal defeats the reknowned grandmaster and raconteur Saviely Tartakower from the black side of a Scotch Game.

Carlsen – Radjabov Match Analysis

admin

[Ed's note: we'll do a proper welcome soon, but we are very pleased to have John Jurgens blogging for us! This is his first post.]

The Carlsen vs Radjabov game bears a strong resemblance to a French Defence structure Kopec anti-Sicilian System. My friend and colleague Lefu Ntho has been scoring heavily with this system which is unfamiliar and very disconcerting to most Sicilian players. Luckily, help is at hand in the form of IM Danny Kopec’s discussion of the system (which can be found in ChessCube’s Shop).

I ran the recent Carlsen victory through Deep Rybka 3 (64 bit) and here is the analysis.
