CHESSBASE: BIEL R6

Carlsen, Dominguez and Bacrot Win
27.07.2008 – All three games reached decisions in round six of the Biel GM tournament. Magnus Carlsen defeated Yannick Pelletier with the black pieces, while co-leader Evgeny Alekseev imploded against Etienne Bacrot. Alexander Onischuk got into trouble against Leinier Dominguez, then turned the game into a theoretical draw, only to lose it when his Cuban opponent played on. Exciting games.

The 41st Biel International Chess Festival is taking place from July 20th - 31st, 2008. The Grandmaster Tournament is a category 18 event with an average rating of 2686. Biel is located in the Canton of Bern, Switzerland, on the north eastern shore of Lake Biel. It is a thoroughly bilingual town – called Biel in German, Bienne in French. Since 2005 the official name has been "Biel/Bienne". About two thirds of the population (52,000) speak German, one third French.

Leinier Dominguez

It was the US vs Cuba, the super-solid GM Alexander Onischuk vs the young-and-ambitious Leinier Dominguez Perez, who went on the offensive on the black side of a Grünfeld Russian System. But Onischuk hung on and traded down to a drawn rook and knight vs rook ending. That is where the action began...

The position, Fritz tells us after due consultation of the endgame tablebases, is a draw – completely and theoretically. But Cuban GM Leinier Dominguez plays on, testing his US American opponent's ability to play it perfectly. 54.Rg8 Nf3+ 55.Kc4 Rb1 56.Kd5 Ng5 57.Ke5 Kg4 58.Kd4 Rd1+ 59.Ke5 Re1+ 60.Kd5 Re7 61.Kd4 Kf5 62.Rf8+ Nf7 63.Ra8 Kf4 64.Rf8 Rd7+ 65.Kc5 Ke4 66.Ra8 Rc7+ 67.Kb4 Kd4 68.Kb3 Ne5 69.Rd8+ Nd7 70.Kb2 Kd3 71.Rh8 Rb7+ 72.Kc1 Nc5 73.Rh3+ Kd4 74.Kc2 Rc7 75.Rh4+ Ne4+ 76.Kb3 Rc8 77.Kb2 Rg8 78.Kb3 Rg2 79.Kb4 Rb2+ 80.Ka3 Rb8 81.Ka4 Kd5 82.Ka3 Nc5 83.Ka2 Ne6 84.Ka3 Nd4 85.Rh7 Rb6 86.Ka2 Kc4 87.Rc7+ Kd3

Dominguez has used 34 of the 50 moves available for his experiment, Onischuk has handled the position flawlessly. Now comes the catastrophe: 88.Rd7?? Allows mate in eight! 88...Kc2 89.Ka3 Nc6 90.Ka4 Rb4+ 91.Ka3 Rb5 and White will be mated in four more moves. 0-1. [Click to replay]


Cuba vs USA in flags: American GM Alexander Onischuk


Magnus Carlsen was clearly thirsting for another victory and went after tournament tail-ender Yannick Pelletier of Switzerland in his usual active, aggressive fashion. It is amazing how grown GMs crack under this pressure from a 17-year-old.

Up until here Yannick Pelletier has been hanging on against Magnus Carlsen's Queen's Indian, by the skin of his teeth. But now the pechvogel (German for unlucky bird) of this tournament, makes a fatal mistake: 27.Qb6? He could have played 27.Rc1 or 27.Bg2. Now Magnus can go into full attack mode, where the lad is ruthless. 27...Bc8 28.Kg2 Ne4 29.f3 Ng5 30.g4 h5 31.Rc1 g6 32.Ng3 Nxh3 33.Kxh3 hxg4+ 34.fxg4 Qh6+ 35.Kg2 Bxg4 36.Qxc5 Re3 [an alternative was 36...Rc8 37.Qa3 Rxe2+ 38.Rxe2 Rxc1+–] 37.Qd4

And thus it ended: 37...Qh3+ 38.Kg1 Rxg3+ 39.hxg3 Qxg3+ 40.Kh1 Bf5 0-1. [Click to replay]


Back in the sole lead: Magnus Carlsen in round six


Etienne Bacrot sacrificed a pawn on move 15 against tournament leader Evgeny Alekseev, without however showing what compensation he had received from it. For a long time it looked as though Alekseev might win and stay in the lead with Magnus Carlsen. A comfortable draw at least seemed to be on the cards. But then Blunder struck.

It is not easy to see why the last move is losing, but Etienne Bacrot works it all out: 34.Rxc6 Raxa7 35.Qd3 b4 36.Rc8+ Kf7 37.Qh7 f5 38.Qg8+ Kf6 39.Rf8+ Rf7 40.Rxf7+ Rxf7

Black is a piece up and completely lost. With the two passed pawns on the sixth White could even play a move like 41.Qxf7 to win. Bacrot has an even more convincing finish: 41.Qd8+ Kg6 42.d7 Nc5 43.Qe8 1-0. [Click to replay]


Slipped to third place: GM Evgeny Alekseev of Russia

Current standings

Magnus Carlsen now leads alone, with a 2843 performance that puts him at number two in the world on the live rating list, just a point and a half behind top GM Vishy Anand. Carlsen and Leinier Dominguez are the only players left who have not tasted defeat in this tournament. The tragic figure is Swiss GM Pelletier, who has scored a total of half a point in six games and is performing at a 2305 level. Wake up, Yannick!

CHESSBASE: KARPOV CUP

Four players tie for first at Karpov Poikovsky tournament
17.07.2008 – The event, named to honour its patron Anatoly Karpov, saw firebrand Alexei Shirov take the sole lead after seven rounds, only to lose fairly traumatically to Vugar Gashimov, a soon-to-be 22-year-old grandmaster from Azerbaijan. All other games were drawn, as were all five games of the final round. In the end Rublevsky, Jakovenko, Gashimov and Shirov shared first. Results, games and statistics.

9th Karpov Tournament in Poikovsky

The 9th Karpov tournament took place from July 8th to 17th 2008 in Poikovsky. The average rating of the participants was 2691, making it a category 18 event.

After seven rounds of play Alexei Shirov was in the sole lead, with 5.0 points, followed half a point behind by two grandmasters, Dmitrij Jakovenko and Sergei Rublevsky (who had led the tournament before that). In round eight all games were drawn, except one: Alexei Shirov lost rather traumatically to Vugar Gashimov. That pushed the Latvian-Spanish GM into a cluster of four players, with Gashimov ascending to the same group.

In the final round all games were drawn (two in less than 20 moves), leaving everything as it was on the previous day. The finals standings for the tournament were as follows:

The draw average was 69%, up from 63% after the first seven rounds. White won a total of ten games, Black was successful in a total of four.

CHESSVILLE: BISHOP OFF-SIDE

by IM Igor Khmelnitsky
You could study the following material either by skipping the test and going directly to the lecture, or start by attempting to figure out on your own what is going on in each of the positions I will be talking about and then proceed to the lecture. If you chose the latter, spend 5-15 minutes on each diagram and record your evaluation and move / plan for the side whose turn it is and sample variations. Then compare your ideas with mine. Let me know how you like the test and the lecture.

Test yourself


All Positions:

1. Check whose move it is.

2. Evaluate position (i.e. White is Better, or Black is Winning, or Equal...)

3. Find the Best move and, if necessary, support it with variations.

4. Answer the question (if there is a specific one)


1. White to Move


IM Igor Khmelnitsky

Igor is a winner of many national and international tournaments in Europe and the United States. At various points during his career, he has won individual encounters with many of the game’s best players - including Lev Alburt, Boris Alterman, Viorel Bologan, Roman Dzindzikhashvili, Vasily Ivanchuk, Alexander Ivanov, Oleg Romanishin, Alexander Shabalov, Evgeniy Sveshnikov, Patrick Wolff, and Alex Yermolinsky. In total, Igor has beaten over 30 different Grandmasters. He has been a participant in the Ukrainian National Championship as well as a three times contestant in the US National Championship.

2. White to Move 3. Black to Move
4. Black to Move 5. Black to Move

Bishop Off-Side

The subject of today’s mini-test is a misplaced bishop. The first two positions should be extremely easy for all, except for true novices.

6. White to Move

STOP - Lecture begins below.

#1. Training position (Khmelnitsky). White is winning the bishop for the pawn after 1.Pf4-f5. The bishop is trapped and attacked by a less valuable piece.

Similar situations often occur in games of novices when the B pins the N (for example Bc8-g4 pinning Nf3) and then is attacked consequently by pawns h and g (or a and b).


1. White to Move


2. White to Move

#2. Training position (Khmelnitsky). White is winning the bishop once again. This time he plays 1.Pb2-b3 cutting the escape route and preparing 2.Kc1-b2. Unlike in the example #1, here Black has a move before his bishop will be attacked. Yet, there is no move that could help.

Similar situations often occur in games of novices when B grabs the pawn on the R file (a or h). Note, that if the black pawn a7 was on a5, Black could play 1...Pa5-a4 2.Kc1-b2 Pa4xb3 3.Pc2xb3. Now the B is protected by the Ra8. Black would have to move the Ra8 to a5, a6 or a7 to free the square for the other rook in anticipation of 4.Rd1-a1.

#3. Training position (Khmelnitsky). Black is able to trap the bishop after 1...Pb6-b5. The direct plan is to run with the king to attack the trapped bishop and win it. The white king can't help the bishop and various attempts to open up the king-side fail as well. Black wins in all lines. Here are some sample variations:

2.Kf4-e3 Ke7-d7 3.Ke3-d3 Kd7-c7 4.Kd3-d4 Kc7-c6, or 2.Pg4-g5 Ph8-h6 freezing the K-side, or 2.Ph5-h6 Pg7xh6 3.Kf4-g3 (3.Kf4-f3 Ke7-d7 4.Kf3-g2 Kd7-c6 5.Kg2-h3 Kc6-b6) 3...Ph6-h5! If interested, please practice with a friend or computer.


3. Black to Move


4. Black to move

#4. This example is from the game Lautier,J - Bauer,C, Championnat de France, 2006. The B on a6 is trapped and is about to be lost. Black is winning. However, you get no points for hasty 1...Rbb6? as after 2.Ba6-c8, the B escapes. Instead, Black played 1....Be8-d7 gaining control over c8. White is losing the bishop for a pawn. For example, 2.Kg1-f2 Rb8-b6 3.Ba6xb5 Rb6xb5 4.Ra3xa7 Rb5xd5.

#5. This training position (Khmelnitsky), is truly amazing in its unexpected simplicity. Looks like White is the one who has the initiative and probably a small advantage. However, after 1...Re8-b8, it is Black who has the winning position. The Ba6 is once again under arrest. White has no good counterplay against Black's plan of sending the king to b6 and then bringing another attacker - the rook on a8, to win the trapped bishop.

Examples 3-5 show you that squares a6, a3, h3, h6 are often not safe for the bishop, when the escape route is (or can be) cut off. The pawn b5 was such a barrier in these examples.


5. Black to Move

#6. Finally, the last position is there to remind you that even on the open board, the bishop may have problems finding a safe spot.


6. White to Move

In this study by Reti (1922), White is winning. He has many moves and your head may start spinning when you try to calculate all possible variations. My suggestions would be - when you don't see a knock-out punch, stop for a moment and ask yourself this questions - what would he do if I did nothing? In this particular position - Black has no useful move. All bishop's moves allow fork with the knight (ex. 1...Bh6-g7 2.Nd4-e6+). Another fork is available after 1...Kc5-d6 - 2.Kd4-f5+. And the remaining king's moves allow the pawn to get through. Hence comes the quiet 1.Kg2-h1 putting Black in zugzwang and winning.

When you don't see a knock-out punch, stop for a moment and ask yourself this question - "what would he do if I did nothing?"

===================================================================

Summary: a bishop is a long ranged piece and needs open space to show its strength in attack. On defense, a bishop is often a solid force as well. Depending on its placement, a bishop's range is anywhere from 7 (ex. from a1, a7) to 13 (ex. from d4 or e5) available squares. When some of these squares become unavailable, the bishop can get into trouble as in the examples shown above. Memorize these typical ideas. Also, remember, that merely trapping the bishop may not be enough to succeed. Two common options - find a way to attack and win the trapped bishop giving you material advantage (examples 1-5) or start actions away from the bishop so it can't participate giving a virtual material advantage (see example in this article).

Benjamin Franklin on Chess

"Chess teaches foresight, by having to plan ahead; vigilance, by
having to keep watch over the whole chess board; caution, by having to
restrain ourselves from making hasty moves; and finally, we learn from
chess the greatest maxim in life - that even when everything seems to
be going badly for us we should not lose heart, but always hoping for
a change for the better, steadfastly continue searching for the
solutions to our problems."

CHESSBASE: KARJAKIN - SHORT

Kiev Life Rapid: Karjakin Beat Short 7.5:2.5
08.07.2008 – They worked together in Nigel's home in Greece, and almost got themselves killed in a traffic accident. But Sergey Karjakin, 25 years younger than Nigel Short, completely outmatched him in the rapid chess match in the Academic Puppet Theatre in Kiev, Ukraine. On the final day the youngster won both games to finish with a five-point lead. Illustrated report.

From 3rd to 7th of July, 2008 British Grandmaster Nigel Short, former World Championship challenger, and Sergey Karyakin, who at twelve became the youngest grandmaster in history, played a ten-game rapid chess match in Kiev (Kyiv). The venue was the Kyiv Academic Puppet Theatre, Grushevskogo Str., 1a, Kyiv. this is the oldest puppet theatre in Ukraine, established in 1927, and today pays host to puppet theatres from all over the world.

Day five – final

Black should be able to hold this position, if only he finds the drawing move: 41...g6! In this rapid chess game Nigel Short doesn't: 41...d4?? 42.Rxb2 (42.Bd5 was an interesting alternative: 42...Qxb1 43.Bxf7+ Kxf7 44.Qxb1) 42...Rxf5 43.Rb8+ Kh7 44.Be4 (the skewer) 44...Bg6 45.Bxf5 Bxf5 46.exd4 a4 47.Ra8 Bd7 48.d5 Kg6 49.Ra7 1-0.

White should be able to hold the draw in this position, but not with: 36.Kd3? Rd1+ 37.Ke2?? The answer is we haven't the foggiest idea. Time trouble? This just hasn't been Loek's tournament. 37...c2 38.f7 Kg7 39.Rxh6 Kxf7 (or 39...c1Q+++–). 0-1.

Black should be able to defend, probably best with 48...Qh1. However at the end of a long battle Kramnik falters: 48...Nf8?? This allows 49.Rf4, which threatens 50.Qxf7, forking the rook and the knight, for which there is no reasonable defence. 1-0.

Final standings

Peter Leko finished at plus two, a score experts predicted would be sufficient to win this event alone. Leko's performance: 2790. In joint second we find Ivanchuk, Mamedyarov, Nepomniachtchi and Gustafsson, all at plus one. Arkadij Naiditsch finished at 50%, which was better than could be expected from his rating. In a startling seventh place with minus one and a 2632 performance we find Vladimir Kramnik, who won Dortmund a record eight times in the past (1995, 1996, 1997, 1998, 2000, 2001, 2006 and 2007).

CHESSDOM: CARLSEN WINS AEROSVIT

The last round game between Sergey Karjakin and Magnus Carlsen was a short but exciting affair. Karjakin wanted to avoid Sicilian Dragon this time and opened with 1.d4, to which Carlsen replied with Gruenfeld Indian defence. White sacrificed a pawn to force dark-squared Bishops exchange and stormed against Black weakened King. Carlsen had to defend for a while, but after the Queen's trade, the resulting position was roughly equal ending and players agreed to draw on 29th move.

After the starting two points from two rounds and disastrous streak in the middle of the tournament, Alexei Shirov won the last two games and reached 50% score. Andrei Volokitin found the key against Berlin Ruy Lopez lock and beat Evgeny Alekseev. He earlier lost in the same variation to compatriot Pavel Eljanov. See GM Mikhail Golubev's excellent game analysis on the official website. Hans Arild Runde updated his "Measure Up" column by including Foros Aerosvit results into July rating list projection. Henrik Carlsen provided plenty of interesting information on his blog.

Round 11 results:
Svidler, Peter ½ - ½ Van Wely, Loek
Ivanchuk, Vassily 1 - 0 Eljanov, Pavel
Karjakin, Sergey ½ - ½ Carlsen, Magnus
Volokitin, Andrei 1 - 0 Alekseev, Evgeny
