Novotny theme

The last few months I have been playing through games from old issues of the magazine "South African Chessplayer" and also trying to solve the positions from "Test Your Chess" and "Test Your Chess 2". These volumes are all about South African chess, and they were all edited by Leonard Reitstein. You are probably wondering, what is the Novotny theme? I first came across it in puzzle 217 from "Test Your Chess":

Korostenski vs Friedrich, Transvaal League 1978

The solution is given at the bottom of this article. Korostenski is a well known problem composer as well as a former SA champion, so he probably found the winning idea very quickly. According to an article on Wikipedia, "The Novotny theme occurs extremely rarely in actual play." Imagine my surprise to find a previously undiscovered Novotny in the pages of the "South African Chessplayer":

Naylor vs Parkin, Randburg Open 1984, after 36.Rf7

Black has just promoted his passed a-pawn, so he ought to be winning, but is threatened with tricks like 37.Rg7+ Kh8 38.Rxd7 and 39.Rf8#. The game continued with 36... Rxd8 37.Rg7+ Kh8 38.Bxd8 Qf1+? 39.Kh2 Qc1? 40.g5! Nf6? 41.Rxf6 Qa3 42.Bxc7 Qb4 43.Kg3 Be2 44.Rf4 Qa3+ 45.Kg2 and Black lost on time. How can Black escape this fate? The answer is given below.






Solution 1: 1.Bg6! so that White can mate on h7 or g7.

Solution 2: either 36... Nf6!! or 36...Qf1+ 37.Kh2 Nf6!! is a rare Novotny theme, with the Knight en prise to 4 different pieces, but it forces the swap of an attacker and wins on the spot. Some lines are 37.R3xf6 Rxf7 38.Rxf7 Rxd8 or 37.Rxc7 Bf1+ 38.Kg3 Qxe5+ or 37.Bxf6 Rxf7 etc.

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!

JR Mthembu Memorial

The first JR Mthembu memorial took place over 2 days, on 18th and 19th February 2017, at the Open Air school in Durban. JR was well known in Durban as a teacher, arbiter and organiser of chess activities. I never knew his first name as everybody just called him JR! He taught chess at the Gordon Road girls school for many years. Some of JR's best known pupils were Tasnim Amra, Cheshni Jeena and Kriti Lalla, who all became female South African champions in their age groups.

The tournament was a close contest, with Henry Oliver leading all the way, until he took draws against Sayen Naidu and Joseph Mwale in the last 2 rounds. Henry came within a whisker of defeating top seed Joseph Mwale in the last round, when he had a completely winning Rook and pawn ending. With 6 seconds left on the clock, he claimed G4 and Joseph had little choice but to accept the draw offer. These two players were joined by unrated Joseph Ambali on 5 points out of 6.

The B section was won by Thacian Reddy, who defeated second placed Archana Datharam in a crucial round 5 encounter.

Here are the section A results and the section B results.

Some interesting endgame positions that caught my eye were:

from round 2, with White to move

White tried 1.Rg3, hoping for 1...Rxg3+ 2.Kxg3 with a drawn pawn ending, and resigned when Black played 1...Kf4. Possibly 1.Kh2 was a better try, although 1...Rb3 looks winning. Why did you resign, asked the spectators? After 1.Rg3 Kf4 2.Rxf3+ Kxf3 3.b5 Black said he intended 3...e3 4.bxa6 e2 5.a7 e1=Q with mate on g3 or h1, and nearly fell off his chair when he was told that 6.a8=Q is check, so White wins! On reflection, simply 3...g4+ forces 4.Kh4 when it is Black who queens with check and wins the game. The next position was even more instructive:

from round 4, with White to move

This came from one of the father-son pairings that my pairings software liked. The game ended with 1.Ra8 a3, draw offered and agreed. Again the kibitzers wanted to know, doesn't Black win after 2.Rxa3 Kb2 3.Re3 c1=Q 4.Rxe4 etc. Indeed, but a little home analysis convinced me that there was a draw by either 2.Ra7! or even 2.Ra6. The point is that 2.Ra7 a2 3.Rxa2 Kb1 4.Rxc2 Kxc2 5.Ke3 is drawn. Even more interesting is that 2.Ra5 fails to draw, because the King can zigzag backwards by 2...Kb2 3.Rb5+ Kc3 4.Rc5+ Kb3 5.Rb5+ Kc4 and one of the pawns will queen.

ECA 1st rapid GP

The first event in the Ethekwini rapid series took place on 4th February 2017 at the Durban Jewish club. Top seed Joseph Mwale secured 1st place by defeating his closest rivals, Wanda Khanyile and Lindo Xulu, in rounds 4 and 5, before coasting to an early draw against Cyril Danisa in the last round. He was followed home by a group of 5 players on 5 points out of 6. Here are the detailed results.

The last game to finish on one of the top boards showed how nervy rapid chess can be:

Black to move and draw

With less than a minute left on the clock, Black started thinking and I expected 1...Rxf4+ 2.Rxf4 Bxf4 3.Kxf4 hxg5+ 4.Kxg5 with a draw. However, Black played 1...Bxf4 and was so surprised by 2.g6! in reply that he resigned! The funny thing is that 2...Rf6 3.Rxf4 Rxf4+ 4.Kxf4 is only a draw, despite what your chess engine might tell you, as the black King gets stalemated in the corner.

Heritage Day open

A one day rapid tournament was held on 24th September in celebration of Heritage Day. The field in the A section was small, but that meant there were lots of upsets and no easy games! Joseph Mwale was a convincing winner, with 5 points from his 6 games, followed by Wanda Khanyile and Cyril Danisa. Sachen Pather scored the most upsets. Here is a diagram from his 5th round game against Wanda, where Sachen blundered a Rook in the opening, but then his opponent relaxed too soon:

Wanda Khanyile (to move) vs Sachen Pather

In this position, White is up 2 pieces, but his King is obviously in great danger. Outside the hall, Joseph opined that Black has a winning attack, but both Lindo and myself thought that White could safely return some of his treasure.

Wanda thought for several minutes, then played 1.Be2, and the game continued 1...Nxc2+ 2.Nxc2 Qa5+! 3.Kf1 Nd2+ 4.Ke1 Ne4+ 5.Kf1 Nd2+ 6.Ke1 Ne4+ and the players agreed a draw. No sooner had they done so, when the kibitzers pointed out the Queen sacrifice 4...Nf3+ 5.Kf1 Qe1+ leads to smothered mate!

The position is well worth analysing. Joseph punted 1.Qg7 as the only defence, but my computer busts his suggestion with the beautiful Queen sacrifice 1...Qxc2!! since 2.Nxc2 Nxc2+ 3.Ke2 Rd2+ 4.Kf3 Rxf2 is mate. It seems that 1.Rc1 was best, but still better for Black!

Here are the results of section A and results of section B.

Fischer memorial rapid 2015

Durban Chess Club hosted a one day Open rapid tournament on Saturday, 7th March 2015 in memory of the late Robert James Fischer, whose birthday was on 9th March. The event was held at Northlands Senior Primary School in Durban North.

As defending champion, I felt obliged to participate, but was completely off form, finishing with 4 wins, 2 draws and a patzer loss to top seed Joseph Mwale. My only consolation was a particularly nice combination in round 2 against Chad Blomeyer, who went on to share the prize for the best under 16 player. This was the position with Black to move:

Rust vs Blomeyer, after White's 26th move

With time running low, Chad pinned the Knight with 26... Rd8 threatening 27... e5. However, White can ignore the threat, and play continued 27. c6! Rbc8 28.c7 Rd7 and now 29.Nf5!! leaves 2 of my 3 pieces en prise, but wins the game after 29... Rxd3 30.Ne7+ Kf8 31.Nxc8 e5 32.Nb6 Be6 33.c8=Q+ Bxc8 34.Rxc8+ Ke7 35.Nxa4 etc. My subsequent home analysis showed that 26... e5 27.Nf5 Rc7 28.c6 Rbc8 29.Rdc3 Kf8 was about equal.

The winner was 3-time Durban champion Bongani Mgaga, who scored 6½ points from his 7 games. Along the way, Bongani had a very lucky escape against Paul Curry in round 3.

With about 90 seconds left on the clock, Paul reached for his Rook and the audience held their breath, expecting him to play 1... Rxh3+ 2.gxh3 Qg1 mate, but Paul placed the Rook on e7 and Bongani somehow managed to draw the game. Bongani's other key game was his round 6 win against 2nd placed Joseph Mwale, with castling on opposite sides of the board followed by a crushing attack on the black King. Also on 6 points, but placed 3rd on tie-break, was Petros Ntombela.

Here are the detailed results of the Fischer memorial rapid.

Max Euwe memorial 2015

The 2015 Max Euwe memorial took place on the weekend of 21st/22nd February at Berea Primary School in Durban. The playing schedule was a grueling 7 rounds of 60/60 over 2 days, so I opted to watch some games instead of playing. There were 61 players, headed by the hot favourite, visiting master Rodwell Makoto of Zimbabwe.

Listening to introductory remarks from the organisers

As early as round 2 the second seed, Erick Takawira, found himself in big trouble. You can see from my photo that he had only a minute left compared to his opponents 16 minutes, in what looked like a lost Bishop ending.

Mkhwanazi (1417) vs Takawira (2052)

From the diagram play continued 1.Bb1+ Kxf4 2.Bxg6 Be8 3.Bb1 Ke5 4.e7 Ke6 5.Kd4 Kxe7 6.Kc3 Ke6 7.Kxb2 and a draw was soon agreed. Afterwards I asked Erick how he would meet 4.Ba2 and he gave 4...Kf4 to which I replied 5.Kd6 Kg4 6.Ke7 Bg6 7.Kf6 Be8 8.g6 and White wins. After reflecting on this, Erick then found 4...b1=Q! 5.Bxb1 Kxe6 and Black draws because he can sacrifice his Bishop for the g-pawn and the h-pawn is the wrong colour to win.

Not so lucky was Bongani Mgaga in his last round encounter with Shivar Gopaulsingh. After catching his opponent out in the opening, he allowed Shivar back into the game, despite having a 20 minute time advantage. From the diagram play continued 1...Qb6+ 2.Kh1 Rd3 3.Qc2?? Rxg3 and Bongani played a few more moves before resigning. My computer gives 3.Qb2 as equal, whilst I was expecting 3.Qc5 from Bongani.
