Chess and maths

It is well known that world champions Emmanuel Lasker and Max Euwe were also mathematicians, but I was quite surprised to realise that I have played chess against five professors of mathematics, namely Peter Dankelmann, John van den Berg and his father Johan, Michael Henning and Max Euwe. I don't believe I have played any other professors! I have also played against a number of actuaries, who are also very good at maths. Is there a connection between chess and maths? Both are based on problem solving. Chess players make extensive use of logic and pattern recognition skills, as do mathematicians. I think this is the reason that playing chess appeals to many mathematicians.

There is a school of thought that says that teaching chess to children is a good thing, as it also teaches them skills that can be used in other fields, such as mathematics.

"Master Moves Kids" provides chess lessons that are linked into the school syllabus. It is supported by donations from many of South Africa's biggest companies. In the picture above, the pupils are learning about files by placing coloured stickers on a chess board. They are also learning about chess notation, number sizes, bar charts and co-ordinates at the same time!

There are lots of possibilities to learn whilst also having fun with chess. Take for example the piece values. When we exchange pieces, you have to add up how much each piece is worth and then say which is greater. Do we win or lose if we trade two minor pieces for a Rook? One final example, how do you move a Rook from a1, so that it touches every square on the board only once? My immediate reaction was the lawn mower method, but there is another, more elegant, solution. Think about it!

SA Junior champions

The 2017 SA Junior Closed chess championships ended recently, with 14 national age group champions being crowned at the closing ceremony on 11th April. My thanks go to Chess SA for inviting me to be an arbiter at this prestigious event, held at the Kopanong Conference Centre in Benoni from the 5th to 11th April. There were 280 players and a team of 8 arbiters, led by Michael Bornheim, to look after them. We had very few issues and I think the event ran smoothly, apart from a few glitches with the DGT boards. These were the latest wifi DGT boards and this was their first outing. One problem was that so many people were using the Kopanong wifi.

Three of the 14 national champions were from KZN! We won two gold medals in the open sections, Kaedan Govender won the under 8 open title, and Naseem Essa was the under 14 open champion. We had hoped for a similar result in the girls sections. I was surprised that Arti Datharam, who received a trophy as South African under 10 player of the year for 2016, finished out of the medals in the under 12 girls. Instead it was her little sister, Archana Datharam, who won the third gold medal! Archana is now the SA under 10 girls champion. Lastly, Charlotte Millard won a bronze medal for her 3rd place in the under 12 girls. Congratulations to all of our medal winners!

Archana Datharam stayed on board 1 for the whole tournament,
scoring 10 points from her 11 games

Kaedan Govender, seen here with his proud parents, did even
better, drawing once and winning all his other games

Naseem Essa, back on board 1 after an early upset, scored 8.5 points
from his 11 games, and won the gold medal in a playoff match

King Cetshwayo 3rd anniversary

The King Cetshwayo district chess association celebrated the third anniversary of its formation over the weekend of 1st/2nd April this year. It was the start of the school holidays, and a new record of 192 players took part in the celebrations! As a large number of players only entered on the morning of the 1st, the organisers had to frantically find another twenty tables and chess sets to squeeze into the hall of Richards Bay High School.

The first day proceeded smoothly for the top seeds, with the only major upset being the draw between Nikash Baboolal (1165) and Samkele Mzimela (500) in the first round of the under 16 section. Samkele also scored upsets in rounds 3, 4 and 5. He went on to finish 3rd in the under 16 section and is clearly a player for the selectors to watch.

On both days there were lucky draws for prizes and everybody got to sample the birthday cake on day 2. Here is a photo of the participants with the birthday cake (click on the photo to enlarge):

The top female players in each section were recognised at the prize giving. See the photo below, from left Luyanda Biyela (under 18 - 4th), Jurina Moodley (under 12 - tied for 1st place on 6 out of 7!), Ntando Dlamini (best adult), Zhime Ntombela (under 16 - 12th), Lisa Griffiths (chairperson), Kiara Pillay (under 14 - 7th), Sibongakonke Singa (under 20 - 5th).

Lastly, here is a photo of Mongezi Shoba, from Nkandla, who finished 2nd in the under 16 category:

In conclusion, here are the detailed results for each of the four sections:
under 10 & 12 group,
under 14 age group,
under 16 age group,
under 18, 20 & adults.

Ethekwini Open report

The 2017 Ethekwini Open was the biggest event of this year's chess calendar in Durban, with a very strong FIDE section and a well attended open section. It took place over 4 days, from 18th to 21st March 2017, with just 2 rounds being played per day. Special guests were GM Sipke Ernst from the Netherlands and IA Chanda Nsakanya from Zambia.

The open section attracted 125 entries and was intended for players rated below 1900. It was played at 90 minutes per player for the game. The top two seeds were Jason Subke (1862) and Clive Mthunzi (1831) and they both reached 4 out of 4 with little trouble. However, Jason could only draw with Mpho Mshope in round 5, so he was half a point behind when the top two duly met in round 6. A tough positional game saw Jason a pawn down in a Rook and pawn ending as time ran short -

Subke vs Mthunzi, Black to move

and this is how the game ended: 1...Re4+ 2.Kd3 Re1 3.Rxd5! (after a long think, he had to see his 6th move here, if 3.Kd2 Re7 4.Rxd5 Kg8 is slightly better for Black) 3...Rd1+ 4.Ke4 Rxd5 5.Kxd5 Kf6 6.h6! (the only move) and the players agreed a draw. They both won in the 7th round, so the final placings were 1st Clive Mthunzi on 6.5, with a 3-way tie for 2nd place between Jason Subke, Ayanda Gumede and Mpho Mashope on 6 points from 7 games.

Prizes for the open section were presented by Sayen Naidu, a former winner of the tournament in 2008. Here are the full results of the open section.

The FIDE section was very interesting, with 7 titled players competing. Obviously grandmaster Sipke Ernst was the favourite to win, but who would finish second, and who could take a draw from him? The standard FIDE time control of 90 minutes plus 30 seconds increment was used, but Sipke played very fast and had all his opponents under pressure. I was very impressed by his willingness to discuss his games and explain his moves afterwards.

All of the games in the FIDE section - 97 games (PGN) - were captured by me, so you can replay the moves at your leisure. I will just highlight some of the moments from Sipke's games:

Johannes Mabusela played 8.b4 here vs Sipke Ernst

"Where did I go wrong?" asked a baffled Mabu. Apparently 8.b4 was incorrect for 2 reasons, the first is that White has nowhere to castle, as the Q-side has big holes and the K-side lacks defenders, the second reason is that the c4 square becomes weak. The game is very instructive.

The closest anybody came to a draw against him was in round 6. It looked like Corno was better for much of the game, and this was the critical moment when the endgame was lost:

Corno Klaver vs Sipke Ernst, White to play

White could sit tight here, with a probable draw, but saw a little combination: 43.c5 Rxc5 44.Rxc5 dxc5 45.Bxf7, which was immediately refuted by 45...Kxf7 46.Kxe5 c4!. The GM knew that the pawn ending was a win for him, as he recognised the 3-2 pattern on the Q-side. Lesser mortals have to calculate the variations!

The most brilliant game of the tournament was unquestionably Sipke's win against Joseph. Here is the game with some variations added with the help of my favourite chess engine!

Here are the final results of the FIDE section and some photos supplied by the chief organiser, Erick Takawira, who did a lot of hard work behind the scenes.
