Bent the Great

One of the most colourful personalities in the chess world ever passed away not long time ago. Bent Larsen, the giant of positional chess, one of the most honest annotators had a profound influence in my chess development. I doubt that I would have made it to the GM title without his book “50 Selected Games”. At first I wanted to annotate some of his games, but then I found this being pointless. The great man has still things to tell us, so why not learn these lessons from his own moves and words:
Larsen,Bent - Gligoric,Svetozar [A05]
Vinkovci Vinkovci (12), 18.10.1970
[Bent Larsen]
1.g3 g6 2.Bg2 Bg7 3.e4 c5 4.Nf3 Nc6 5.0–0 Nf6 6.d3 0–0 7.Re1 d6 8.Nbd2 Rb8 9.a4 There are two more plans that deserve attention here- preparation of the b2-b4 advance or d3-d4. The position of Nc4 has only aestetical value. 9...b6 10.Nc4 Bb7


"I will write about this tournament an article in which there will be only one diagram. Now you will see the most amazing move of tournament, but not a bad one at all!" Petrosian. 11.h4!? A difficult, but profitable decision. [11.e5 was the most natural move, with great danger of exchanges and draw.] 11...Qc7 White's idea is seen in the line: [11...d5 12.exd5 Nxd5 13.h5 with initiative.] 12.Bd2 Rbd8 13.Qc1 d5 14.Bf4 Qc8 15.exd5 Nxd5 16.Bh6 Rfe8 After the game people were suggesting: [16...f6 to which I would have replied- 17.h5] 17.Bxg7 Kxg7 18.h5 Nf6 19.h6+ Kg8 20.Qf4 Nh5 [20...Qg4 was losing at least a pawn after: 21.Rxe7!; Bad for Black is: 20...Qf5 21.Qxf5 gxf5 22.Ng5!] 21.Qd2 f6?


22.a5! This move is especially unpleasant precisely now, when the black knight on h5 is inactive, and the set-up with e7-e5 and Nc6-d4 is not yet dangerous for White. 22...b5 23.a6 Ba8 24.Na5 e5 25.Qc3 Black underestimated this move. Now White has an advantage in all the lines. 25...Nd4 26.Nb7! Bxb7 27.axb7 Qxb7 28.Nxd4 cxd4 29.Bxb7 dxc3 30.bxc3 Re7 31.Rxa7 Kf8 32.Rb1 f5 33.Rxb5 Nf6 34.Ra8 Rxa8 35.Bxa8 Ng4 36.Rb8+ Kf7 After: [36...Re8 37.Rxe8+ Kxe8 38.Bd5 Nxh6 39.f3!


39...g5 40.Kf2 g4 41.f4 White is winning easily, as the black knight is locked.] 37.Bd5+ Kf6 38.c4 e4! The last try. 39.Rf8+! Ke5 This might seem a bit unexpected, but after: [39...Kg5 the king is too far away from c file, and analyses show easy road to the win: 40.dxe4 fxe4 41.c5 e3 42.fxe3 Rxe3 43.c4!] 40.dxe4 fxe4 41.Bxe4 Nxh6 42.Bd3 Nf7 43.Rg8 Nd6 The sealed move. In my home analyses I found win in all lines: 44.Ra8 Nb7 [44...Rc7 45.Ra5+ Kf6 46.Ra6 Ke7 47.Ra4 Kf6 48.f3 Rc6 49.Kf2 h6 50.c5!


with the following subtlety: 50...Rxc5 (50...Nf7 51.Be4 Rxc5 52.Ra6+) 51.Ra6 Rd5 52.Be4 Rd4 53.c3 and wins.] 45.Ra7 Kd6 46.f3 Nc5 47.Rxe7 Kxe7 48.Kf2 Kf6 49.Ke3 h5 50.Kd4 Ne6+ 51.Kd5 g5 52.Kd6 h4 53.gxh4 gxh4 54.Bf1 Ng5 55.c5 Nf7+ 56.Kd5 Ke7 57.f4 Nh6 58.Bh3


58...Ng8 59.c6 Nf6+ 60.Ke5 Ne8 61.f5 1–0

Plovdiv Again

ECC in Plovdiv had started with a small crisis when the NATO soldiers decided that the dates of the tournament are perfectly suitable for them too to occupy the building. One problem is that Novotel has a contract with the NATO forces that gives them the possibility to use it any day they want. The other problem is that the American soldiers does not want anyone else on the floor where they have people, no matter if the floor is full or not. These things caused some inconvenience with the accommodation of the players. Still, place for those rated over 2700 for the open event, and over 2500 in the ladies part was duly reserved.


The freshly elected presidents Kirsan Ilyumzhinov and Silvio Danailov presented at the opening ceremony. The ECU President also made the symbolic first moves on both the male and female boards at the start of the tournament.
The colour of Europe meets in Plovdiv in the open section. Except for those who participate now in Nanjing all the best players are practically here.


The top seeded Levon Aronian shines so far in the event with a rating performance of 3000 elo points. His Mika Yerevan (practically the Armenian national team) will try to overcome the one point deficit in a direct encounter against the leaders- Economist Saratov, who had won all their matches so far. The latter also has a top scorer- Alexander Moiseenko, who has 4.5/5, but the truth is that both teams has practically no weak point, and the match will be decided on very minuscule nuances. Some more top scorers include Alexander Grishchuk 4/4 and Vladimir Malakhov 4.5/5.
The female tournament is extremely strong, too. The ladies from AVS, led by Antoaneta Sefanova are leading in the female part. However, four teams are pursuing them a point behind. Nothing will be clear there until the very last game. Koneru, Atalik, Zaiatz and Galojan are the top scorers after the fifth round.


As a tradition the nations are of no big meaning here. We can see players from China, India and USA taking part in the European event, and this is normal. We can also observe couples playing in the same teams, or in two different teams. The Zhigalko brothers for example play for two different teams-one leads a team from home country Belarus, and the other one strengthens an Ukrainian one.
One of our journalists even joked that there are some illegal Bulgarians here-those who do not represent our country.
I am one of those, as I play for my Belgium team. We also have a couple of German players (one of them is surprisingly fluent in Russian, too), and a Dutch guy (also illegal I might add). And there are teams who have player only from different countries. Just have a look at the team Werder Bremen- the apotheoses of internationality.


As my Belgium teammates have never been yet in Bulgaria, we went to a typical Bulgarian restaurant. Vesloto selo (The “Jolly Village”) was especially good for this reason. The food starts with our typical rakia (not to be confused with the Turkish raki, ours is made by fruits and does not smell like anise!), then follows the rich meat main course. In the meanwhile the entertaining program have started, which includes various Balkan rhythms- Greek, Serbian, Gypsies, Oriental. It all ends with the traditional Bulgarian dance-horo, which my teammates learn with surprising speed.
The preparation was a huge success, and next day we comfortably lose 6-0.

Positional Sac in the Trompy

Ety's best achievement in Ulanbaatar was the following game:
Stefanova Antoaneta - Kosintseva Tatiana [D00]
Ulaanbaatar GP Mongolia
[Dejan Bojkov]
1.d4 Nf6 2.Bg5 A time for a change. In their previous encounter just a month ago in Jermuk the players tested the main lines of the Ragozin. However, Tatiana is definetely well prepared against the Trompy, too. 2...d5 3.e3 g6 4.Bxf6 exf6 5.Ne2 Bd6 6.g3 c6 7.Bg2


7...f5! A good idea. Black was less precise in the following game: [7...Nd7 8.b3 f5 9.c4 Nf6 10.Nbc3 Be6 11.c5 and White achieved harmony in his development and initiative on the queen's flank. 11...Bc7 12.b4 a6 13.a4 0–0 14.0–0 g5 15.b5 Qd7 16.Qd3 Kg7 17.f4! Laznicka,V (2617)-Mamedov,N (2614)/Benasque ESP 2009/The Week in Chess 766 (42) with pleasant advantage for White who won later.] 8.b3 Be6 Now Black forces her opponent to lose some time before advancing the c pawn. 9.Qd3 Nd7 10.Nd2 Nf6 11.c4 Ne4 12.c5 Bc7 13.b4 h5 Both players wait with the kingside castling. 14.Nf3 Qf6 15.h4 Qg7 The trick: [15...a5 16.b5 (16.0–0 axb4 17.Rfb1 Ba5 18.a3 is also good for White.) 16...Nxc5 does not really work as the c6 pawn is hanging: 17.Qc2 Ne4 18.bxc6 b6 19.0–0 0–0 20.Rab1±] 16.0–0 Now when h5-h4 is stopped White can finally castle. She has though to hurry with her play on the queen's flank. 16...f6 17.b5 g5 Kosintseva straightforwardly follows her plan. However, a little profilaxis might be better here: [17...Bc8 18.Rab1 0–0 19.Rb2 (19.Nf4 does not prevent g6-g5, as the knight might be trapped after: 19...g5 20.Nxh5? Qf7 traps the knight) 19...g5 with sharp play where both sides have their share of chances.] 18.bxc6 bxc6 19.Qa6 Bd7 20.Rab1 0–0


21.Rb7! A nice positional sacrifice. Ety will gain control over the light squares thanks to the invested exchange. 21...Bc8 22.Rfb1 Worse is: [22.hxg5 Rb8 23.Rfb1 Qd7 24.gxf6 Bd8! However, objectevely best seemed to be:; 22.Qxc6 Bxb7 23.Qxb7 Rfd8 24.hxg5 fxg5 25.Qc6 with full compensation for the exchange.] 22...Bxb7 There is nothing wrong with this move, but White's task would have been much more complicated after: [22...Qd7! with the idea to exchange both the white rooks. Play may continue: 23.hxg5 (23.Rxc7?! Qxc7 24.Qa3 Rb8µ) 23...Rb8 and now the highly entertaining sacrifice: 24.gxf6!


In the line: (24.Qxa7?! Bxb7 25.Rxb7 Rxb7 26.Qxb7 Rb8 27.Qa7 (27.Qa6 fxg5) 27...Rb1+ 28.Bf1 Nxg5 29.Nh4 White seems in control, but there is a tactical stroke: 29...Nh3+ 30.Kg2 Nxf2!) 24...Bd8 25.Rxb8 Bxa6 26.Ne5 Qc7 27.Nf4! Better than: (27.f7+ Rxf7 (27...Kg7 28.Nf4 Ng5 29.Nxh5+ Kh6 30.Nf4ч) 28.Nxf7 Kxf7 29.Nf4 Bb5!µ) 27...Bc8 (27...Rxf6 28.Ra8 Kh7 Here: (28...Bb5? loses to: 29.Rxb5 cxb5 30.Bxe4 dxe4 31.Nd5+-) 29.Rbb8 Bb7 30.Rxd8 Bxa8 31.Rd7+ Qxd7 32.Nxd7 Rf7 33.Ne5±) 28.f7+ Rxf7 29.Nxf7 Kxf7 30.Ra8


and it is difficult to judge who is better, but obviously White should have at least enough for her sacrificed piece.] 23.Rxb7 Qd7 24.hxg5! Ety looks for juicy squares for her knights. 24...Nxg5 The only move, as Black's position crumbles after: [24...fxg5 25.Ne5 Qg7 26.Qxc6+-] 25.Nh4 [25.Nxg5 is enough only for a draw, as after: 25...fxg5 26.Bxd5+ cxd5 27.Qg6+ Qg7 28.Qxg7+ Kxg7 29.Rxc7+ Black can harass the active rook- 29...Rf7=; 25.Nf4!? though deserved serious attention: 25...Rab8 only move (25...Rfb8? 26.Nxg5 fxg5 27.Nxd5! cxd5 28.Qg6+ Kf8 29.Qh6+ Qg7 (29...Ke8 30.c6 Qe7 31.Rxc7 Qxc7 32.Qh8+ Ke7 33.Qg7+ Kd6 34.Qf6#) 30.Qxg7+ Kxg7 31.Rxc7+ Kf6 32.Bxd5+-) 26.Nh4 (26.Nxh5 Rxb7 27.Qxb7 Kf7 28.Nh4 also gives great compensation to White.) 26...Rxb7 27.Qxb7 Rb8 28.Qxa7 Rb1+ 29.Kh2 (29.Bf1 Qc8 30.Nxh5 Ne4) 29...Ne4 30.Bxe4 fxe4 31.Kg2 and I would love to have White here.(31.Nxh5? Bxg3+) ] 25...Rfb8 26.Nf4 White is better, although the computer claims that the position is equal (it already sees the only salvation that Black has though). However, for a human being defending both the king and all the pawn weaknesses without having any active plan is a painful task. Moreover, if both the humans are in time trouble this task becomes impossible for the defender. Tatiana soon erred. 26...Rxb7 27.Qxb7 Rb8 28.Qxa7 Ne4 29.Bh3 Rb1+? The rook had to stay on the eight rank in order to protect the king. [29...Qc8! with the idea: 30.Bxf5 (30.Nxf5 Qb7 31.Ne7+ Kf8 32.Qxb7 Rxb7 33.Nxc6 Bxf4 34.gxf4 Rb1+ 35.Kg2 Rb2) 30...Ra8!


was Black's only chance. After: 31.Bxc8 Rxa7 32.Bd7!? Bxf4 33.Bxc6 Nxg3 34.Bxd5+ Kh7 35.Ng2 Bc7 36.fxg3 Bxg3 the position is approximately ballanced.] 30.Kg2 Rb2 31.Bxf5 Qg7 [31...Rxf2+ 32.Kg1 Qd8 33.Bxe4 and wins.] 32.Nxh5 Rxf2+ 33.Kg1 Qh6 34.Qa8+ Qf8 35.Be6+ 1–0

Three Weeks in Mongolia (for NIC)


We work with Ety since October 2009. My contract obligations included the tournaments from the Women Grand Prix series. These tournaments were created only a couple of years ago in attempt to lift the image of the women chess all over the world. The initial idea was that they are rapid events, but later it grew in something more substantial. The stakes in this circuit are high. The overall winner of the event receives the right to play a match against the World Champion who must be defined at the end of this year in Turkey. Therefore almost all the best women players take part in the event. In the strength of the players the tournaments can be compared to the super male round-robins, such as Linares and Wijk an Zee. A fact that was not seen lately in the women chess world. It is not a secret that most of the ladies compete in usual opens, and the one in Gibraltar for example brings together the cream of the female elite with the attractive prize fund and the opportunity to win prices in both men and women sections.
The Grand Prix series consist of six tournaments (Istanbul (Turkey), Nanjing (China), Nalchik (Russia), Jermuk (Armenia), Ulaanbaatar (Mongolia) and Santiago (Chile), and each player can compete in maximum four of them. The best three are counted for the overall standings. Each host country has the right of a participant in the series.
Speaking of the world championship system we never have clearance. Of lately the Russian chess federation came with a new proposal that adds two more players in the fight for the title-the current World Champion Alexandra Kosteniuk and the last spot is left free for the top rated female player.
In my personal opinion the Mongolian Grand Prix was the strongest of them all. Four former World Champions took part in the event, as well as the top three rated players (we if of course exclude J. Polgar).
The further expansion of the chess popularity is very welcomed. Mongolia is relatively new destination on the chess map, although as a former communist country largely influenced by USSR our sport is very popular there. We lived in the closed area Ikh Tenger which is the president’s complex.
In the day of the opening ceremony the new Chess Academy was opened by Kirsan Ilymzhinov himself. The FIDE president had a very busy schedule due to his elections campaign but nevertheless found time to open the tournament, just like he did in Jermuk. In the center of the town, in front of the monument of Mongolian’s most famous personality-Chingiz Khan the ladies picked their numbers in alphabetical order of names. Curiously, those who started first were picking up the small numbers and the more white pieces.
The ladies play the way with the Sofia rules and they cannot agree short draws. This probably is not needed as they all are proved fighters and like to play till the end. The chief adviser for the draw offers in the event was the legendary Nana Aleksandria from Georgia and her opponent for the World Championship in 1981 Maia Chiburdanidze was participating in the competition.
The initial rounds define the roles in a tournament, and show who will play the role of an underdog, and who will compete for the top places.
Ety started with two draws, and the second one was especially unpleasant as she spoiled huge advantage in her time trouble against Maia Chiburdanidze. In the next eight rounds though, she would take no prisoners, scoring six wins against two losses.
As the tournament equator was reaching the column was led by the Chinese Zhao Xue. Her wins though were not very impressive; one could find many twists in her games, and decisive changes in the evaluation of the positions. Her game against Zhu Chen was especially significant in that sense. First White was completely winning, and then came a huge blunder and it was Black who was winning. Finally the game reached the position on the diagram:
Zhu Chen - Zhao Xue
Ulaanbaatar GP Mongolia


Without spending more than a second on her next move the former women champion played: 64.Kb8?? Instead the precise [64.Ka8!= would save the day- 64...Qe8+ 65.Kb7 Qe4+ 66.Kb8 Qb1+ 67.Ka7 Qa2+ 68.Kb8 Qh2 69.Ka8] and resigned after: 64...Kc5 65.Ka8 Qd7 66.Kb8 Kb6 0–1

The logic of the events was telling that Zhao should not keep the lead. Indeed in the very next round she was technically outplayed by Tatiana Kosintseva. The Russian player had no other alternative in this tournament but first place, as due to the engagements with her Russian club for ECC in Ohrid 2009 she could play only three Grand Prix tournaments. Tatiana was playing in her usual solid manner, but in the very next round she was stopped by Ety.
This was a period when the leaders were constantly changing their places and none could really predict the overall winner. Ety was replaced in the lead by top seed Humpy Koneru, then the Indian lost to Zhao, and this finally gave a chance to Hou Yifan to grab the lead after her postponed win against Zhu Chen. The young Chinese had a critical moment in round eight when she had to visit the hospital due to health problems. Luckily for her this round was the one before the second free day, and her opponent generously agreed for a postponement. How Hou won this important game you can see with her own notes.
Most of the participants had problems with the food throughout the whole event. I do not why it was happening like that-normally it was delicious, and I cannot call it exotic, but it was obviously the overall change that mattered.
As in a good movie the tournament winner had to be decided in the final round. Hou Yifan was leading with a half point advance in front of Ety, but we had the white pieces. An unpleasant change in the program spoilt a bit the tournament finish when the players were asked to play at 10.00 a.m. The organizers insisted on this hour as it would give them a chance for a comfortable closing ceremony at the theater, and as there were public speeches scheduled for later in the evening, the closing should take place at five p.m. in fact the organizer’s second proposal was that the games start at 9.00 a.m...For an owl like Ety such a change had a huge psychological impact. We tried to protest, taking on the account the fact that for such a change there should be the signature of the FIDE president, but the FIDE official could not contact him. There was only one critical moment in the game, but it could have changed the name of the winner.
Stefanova,A (2560) - Hou Yifan (2577) [A14]
5th FIDE GP w Ulaanbaatar MGL (11), 11.08.2010


After a stubborn and careful defense Hou Yifan decided to activate her knight with:28...Nb5? But this moves blunders a whole pawn. However Ety also missed the chance- 29.e4? The simple: [29.Bxf6 wins a pawn as the line 29…Rxf6? 30.Rc2 loses even more material. Now the position is balanced again and draw was agreed after sixty moves.] 1/2
Thus the young Chinese remained the only undefeated player, and deservedly won the tournament. The tradition that in each tournament from the series there is a new winner was kept. Stefanova finished clear second, and there was a tie for the third place with Kosintseva, Zhao and Koneru to finish in this order.
We arrived a couple days before the start of the event, and had some time to visit the local attractions- the Gandantegchenling Monastery and the Migjed Janraisig, the Bodhisattva of Compassion, the symbols of the Mongolians-the bell tents (called yurts) in some of which there are still people living. That was all the fun as during the tournament I lived like a hermit and worked in the hotel. The first free day could be a change as there were meetings with the sponsors organized, but the door-knob of my room decided to take a day off, and I was left locked inside for some hours. The previous day I asked Ety if she would like to go to these meetings or she would rather prefer to stay and have some rest to which she replied: “We are all complaining for the lack of sponsors, but when a time comes for a single sign of respect everyone tries to cover himself. I have my obligations to these people, and I need to go.” However when in the second free day the organizers made a large entertaining program with museums, horse riding and archering she preferred to skip the attractions and have some rest for the decisive rounds.
A quick look at the overall standings of the Grand Prix events reveals that the leader now is Hou Yifan with one first, one second, and one shared second places or total of 410 points. However, she already accomplished her tournaments and has to wait and see if some of her two closest rivals Nana Dzagnidze or Humpy Koneru might catch up with her. The final stage is scheduled in Chile, but the earthquakes might hinder the organizational process. There are rumours already that the tournament will be postponed, or even cancelled.
In any case for the good of the women chess I hope that these Grand Prix series will continue in the future.

Belogradchik Rocks (Pictures-Eddie)


When this May while playing the Bulgarian teams Eddie told me that he is organizing an amateur tournament at the beginning of September in Belogradchik, I found the idea fabulous. This was the first time that such an event would take place in Bulgaria, and the things that he told me about the organization convinced me that it is worth the efforts. I met him in…Milano, Italy when he came for a tournament from France where his future wife was studying. Nowadays Evtim Stefanov is the president of the Bulgarian team champion- Nayden Voynov-Vidin, and organizer of the First Blakan Amateur Tournament in Belogradchik.
This small town is chosen for a host city for a good reason. It is located near the capital Sofia, and is exuberant in natural wonders, the most famous one being the Belogradchik Rocks with their weird forms and shapes. The rock figures are approximately 200 meters tall, and there are altogether three groups. The central and biggest one of them is right next to Belogradchik.


A total of 110 players took part in the event, from fifteen different countries, and almost all continents. The tournament became huge success, and we are starting head over feet with the final standings:
The winner of the festival with total 7.5 points was Naiden Dobrev from Dobrich. He is a young player, and started viciously not to let any chance for his closest pursuers- Yanko Panayotov (second) and Momchil Todorov (third) (all from Bulgaria). Dimitar Krastanov was ranked fourth and became a champion among the players without FIDE rating. Best rating performance was delivered by Velizar Sofranov, who managed to make 7 points thanks to excellent play and the training of the Grandmaster team. The winners received a total of 15 000lv /about 7500euro/ of total 18 prizes. Not a bad price fund at all, it can easily compete with any open event.
The mayor of Belogradchik, Mr. Emil Tsankov personally awarded the winners of the festival with the medal of honour of Municipality Belogradchik and invited all the players to visit again the next year tournament in mid August 2011 for its second edition.
However, this was not all that the tournament can be proud of. Many beside activities took place. There was a voting for a queen of the event, which was won by Simoneta Ivanova. She is only 13 from Pleven and already chess queen of the first Balkan amateur chess festival. She was elected by the participants in the tournament. Two more chess ladies received gifts from Municipality Belogradchik and Chess Club Naiden Voinov. These are Tsveta Galunova from Veliko Tarnovo and Silvia-Raluca Sgircea from Dobreta Turnu Severin, Romania. At the ceremony Saturday evening at a glass of wine the manager of hotel “Skalite” presented the festival queen with a body peeling spa therapy with chocolate and honey.
On Friday night 54 players entered a blitz battle in 9 rounds. After a tense fight Bogidar Ivanov won the tournament with 7 wins and 2 draws. Dejan Dimitrov (former chess trainer, and sports journalist at the moment) finished second and the leader in the main tournament Naiden Dobrev ended third.


Additionally a team blitz took place. The winners were Plamen Vasilev and Dimitar Pashev from Bulgaria. Second finished the Macedonians Vladimirov and Semshiu and enjoyed a professional massage in spa hotel Skalite for both of them and Hristo Velchev and Tsvetelin Stoev finished third and rolled downhill in a big zorbing ball.


The activities included lessons with GMs. Some of the participants profited from their work with GM Delchev, GM Iotov and FM Velchev. All these title-holders are members of the Nayden Voinov team that won the Bulgarian championship this year. Those masters were analysing the best games of the festival in the evenings with tons of humor and intelligence. The participants could also take part in the analyses, and gave their opinion. Those lectures were completely free of charge. Furthermore, there were private or group lessons for those willing to take part.
Four excursions were organized for the players. They visited “Kaleto”, the Magura cave, “Baba Vida” fortress and to ride a buggy in the famous Belogradchik rocks.
The second edition of the festival is scheduled for August 2011. We will be happy to see more people joining it.

The Bishop Fortress

Kunte,A (2528) - Fernandez,Dan SIN (2299) [E90]
Sydney Int Open Parramatta AUS (9), 11.04.2010


This was one of the decisive games at the SIO open in April. In case that one of the players have won his game, he would have tied for the first place. In addition, if the second player-young Daniel Fernandez from Singapoore had won, he would have achieved a GM norm. 43.Re7? Kunte is rushing at a moment when he did not need to do that. Now Black had a chance to create a beautiful fortress thanks to his bishop pair. 43...fxg4!! White was obviouly counting on the line: [43...Qa2? 44.Nxe5 Now both the black bishops and his king are in danger. 44...Qa1+ 45.Kh2 Bxe5+ 46.Qxe5 Qxe5+ 47.Rxe5+- where he is easily winning.] 44.Rxe6 Bxe6 45.hxg4 Kh7 Of course not: [45...Bxg4?? 46.Qc4+ However, Black does not necessarily need the g4 pawn to biuld a fortress thanks to his bishops.] 46.f3 Ba2 47.Qe7 Bb1 48.Kf2 The other possible plan would have been: [48.g5!? h5 49.g4 with the idea to open the h file, bring his king to f7, and finally use the h file to create mating threats. However, the subtle: 49...hxg4 50.fxg4 e4=


Prevents the white king from reaching the f7 square. When the bishop are placed on neighbour diagonals they can cooperate in their best possible way. ] 48...g5 This is a correct decision, Black is getting ready to exchange as many pawns as needed. 49.Ke3 Bg6 50.Kd2 Kg8 51.Qe6+ Kh7 52.g3 Or: [52.Kc3 e4+ 53.Kc4 exf3 54.gxf3 Bb2 55.Kc5


with the idea to bring the king to f8, but this does not prove successful, as Black always have the possibility to chase it away with a check from g7, thus keeping his king in safety.] 52...Bh8 53.Ke3 Bg7 54.f4 exf4+ 55.gxf4 gxf4+ 56.Kxf4 Bh8 57.g5 h5! The last finesse. In case of:[57...hxg5+?? 58.Kxg5 The white king will spoil Black's coordination, and the queen can show her best features: 58...Bb1 59.Qd7+ Bg7 60.Qh3+


60...Kg8 61.Qb3+] 1/2 When treated carefully, the bishop prove that they are not worse than the queen.

After a busy summer, I finally have some time left for my bloggy (as the Dutch might say). The second Chess Mentor Course will be soon out, and I like to present you one of the samples:

One of the most unpleasant endgames for the bishop is the so called "French" one- a position that usually arises after the same defense. Even if there are pawns left only on one side of the board, the defender is in great danger for the variouz zugzwangs that can arise, and the lack of space. The bishop also is not much of a help in the defense.


40.Nc8+ White first gains some space. 40...Kf8 41.Kd8 Bc6 42.Nd6 Ba4 43.c4! Although the exchanges usually favour the defender here this one is perfectly justified, as White needs the e4 square for his knight. 43...dxc4 44.Nxc4 Bb5 45.Nd6 Bc6 Covering both e4 and e8, but the next moves forces a zugzwang. 46.h4!


46...Ba4 47.Ne4 Bb5 48.Nf6 Ba4 Black cannot allow the opponent's king come closer. [48...Kg7 49.Ke7 with the threats Nf6-e4 (e8)-d6 and wins all the pawns. 49...Bc6 50.Ng4 and Nh6xf7 to follow.] 49.Nxh7+ Kg7 50.Nf6 Kf8 White won a pawn, and now needed only to discover the beautiful breakthrough idea in the pawn endgame. 51.Kc7?! The win was:[51.Nd7+! Kg8 a) 51...Kg7 changes nothing. 52.Nb6 Bb5 53.Ke7; b) 51...Bxd7 52.Kxd7 Kg8 53.Ke8! Kg7 54.Ke7 Kg8


55.h5!! (55.f5 gxf5) 55...gxh5 56.f5 exf5 57.g6 fxg6 58.Kd7 h4 59.e6 h3 60.e7 h2 61.e8Q+ check!; 52.Nb6 Bb5 53.Ke7 Bd3 54.Nc8 Kg7 55.Nd6 Be2 56.Nxf7] 51...Ke7 52.Ne4 Bc2 53.Nd6 Ba4 54.Nc8+ Ke8 55.Kd6 Bb5 56.Nb6 Kd8 57.Kc5 Be2 58.Na4 Bf3 59.Nc3 Ke7 60.Nb5 Kd7 61.Nd6 Ke7 62.Kb6 Bd1 63.Kc7 Ba4 64.Ne4 Bc2 65.Nf6 Bd1 66.Kc6 Be2 67.Kc5 Bd1 68.Kd4 Bf3 69.Ke3 Bd1 70.Nh7 Bh5 71.Kf2


71...Bd1 72.Kg3 Be2 73.Kg2 Bd1 74.Kf2 Bg4 75.Kg3 Bd1 76.Nf6 Be2 77.h5 gxh5 78.Kh4 Bd1 79.Nxh5 Be2 80.Ng3 Bf3 81.Nf1 Be2 82.Ne3 Kf8 83.Kg3 Bd3 84.Kf2 Kg7 85.Ke1 Kg6 86.Kd2 Bb5 87.Kc3 Kh5 88.Kd4 Kh4 89.Kc5 Ba6 1/2
