Maxime's Revenge

Starting from yesterday I will do regular analyzes on the most interesting event for chess.com
Currently the attention is focused on the Grand Prix tournament in Tashkent which gathers together some of the top players in the world.
The game that everyone expected was between Maxime Vachier-Lagrave and Fabiano Caruana. The French GM is showing constant progress in his play but was defeated twice recently by Caruana (in Saint Louis). Maxime also had a birthday that day and he obviously decided to take care of the present himself.

The solution of the problem would be the proper equipment with a base of knowledge. You do not need to know every single endgame by heart. It is hardly possible (except perhaps for a genius like Ivanchuk) but more importantly it is not worth memorizing countless endgames which are very unlikely to happen.
On the other hand each player should owe an existence minimum of exact positions in every major endgame (pawns above all but also knight/bishop/rook/queen) endgames. This will help the players a chance to orientate in most of the situations, will suggest them which pieces to trade and which to keep and naturally will support the calculation.
Best of luck in building your own memory library!

Know How in the Pawn Endgames (1)

Concept:
The knowledge of exact positions is the cornerstone in the understanding of the pawn endgames.
The pawn endgames have their own specifics. Contrary to the other endgames where we can use approximate evaluations like slightly better/worse or much better/worse without definite conclusion, in the pawn endgames we use only three evaluations- win/draw/loss.
The lack of material enables us to calculate the lines till the end but this is easier said than done. At the end of the game players are usually tired and tend to make more mistakes. The time troubles also do not contribute to the proper calculations.
To sum the things up- pawn endgames can be easily compared to mathematical task where you have only one true answer. In order to find this answer the knowledge of a concrete theorem is needed in mathematics, while in chess that would be the knowledge of a concrete exact position.
Let's have a look of a case where one of the opponents is lacking essential exact knowledge. The following game was played at the first Metropolitan open tournament in Los Angeles three years ago. The player who has the white pieces is a strong national master Mikhail Langer. His opponent is a young and promising IM from Canada, Raja Panjwani. It was actually Raja who showed me the game immediately after it was over. It is a strange coincidence as you will see in a moment. In the diagrammed position White chose the natural looking:

Panjwani did his homework which cannot be said for his opponent. He knew long before the game the following classical example:
The lack of know-how prevented Langer of saving the half point after a tough and accurate resistance. Panjwani on the other hand knew the position and if the colours were reversed he would have easily saved the game. The knowledge helped him in the game as well as he knew exactly how to win after his opponent committed a mistake.

Stalemate Steals the Point

Round eight of the Olympiad appeared to be tough for the PNG team. we were facing Gambia.



It started with a more or less expected loss on board four where Craig Skehan played unnecessary timidly to his opponent.
Things got worse soon as the top scorer of the team Stuart Fancy also suffered a defeat to Ebrima Bah. This was one of his very few losses but in a highly important situation.
It seems as the chances for something are over as Helmut Marko was in trouble on board two.However, with persistance and will the Austrian born CM managed to outwit his opponent and score for PNG.
All had to be decided in the game Bittaye-Jones. Rupert enjoyed an excellent preparation and soon emerged a pawn ahead, clearly better.


After some imprecise decisions by both sides the following position was reached:

PNG Breaks the Tradition

After laughing heartily on my friend's stories of nearly missed flights I could not miss a chance to miss my own. There is always a first time to do something wrong. Well, the moment was not a very good one. Just try to find a flight to Tromso at the very last moment at the beginning of the Olympiad. Or simply ask Hikaru Nakamura on his experience.
Anyway, after three hours of a thorough research I found an option! And arrived just in time for the first round.
True, my Papua New Guinea team lost traditionally at the beginning with a 0-4 result to Singapore. But yesterday we broke "the tradition" and took good 1.5 points in our second match.
Our top board Stuart Fancy produced a bold positional sacrifice at the position on the diagram:

In Asuncion



The Panamercian U20 Junior championships were scheduled to take place in the middle of May. For various reasons the dates were moved to the end of June (21-28) and this gave a chance to my student Ashritha Eswaran from USA to take part in the event.
Panamerican championships gather together the players from both South and North America. However, it is not very usual for the North American players to participate at these events. One of the reasons is the distance. Another, I suspect is the language barrier. In most of the South American countries people hardly speak English.


This was not the case though in Paraguay. The organizer of the event Ronald Zarza Pelissier is a man of German origin and speaks fluently Deutsch. His English is also very good. Add to these linguistic advantages the pure will to help and you will know why Asuncion was a very successful host of the event.
The tournament took place in the offices of the ABC color downtown. The venue was easily accessible and comfortable.
Players from eleven countries took part in the women event. The top seed and experienced Ann Chumpitaz of Peru played steadily throughout the event and won the trophy convincingly with 8/9.


Ann is already an established player; she participated at the Olympiad in Istanbul. In general, Peru dominated the event. The silver was claimed by a very talented Mitzy Mishe Caballero Quijano. She scored 7.5/9. Just like Ann she did not lose a game. However there is an important difference between the two players. Chumpitaz played her last championship while Mitzy is only thirteen years old!
The charming Ivette Ale Garcia Morales took bronze. This is a huge achievement for her country and Ivette hopes that Mexico will show even better results in the future.


Ashritha Eswaran took good fifth place, which would not be too bad if we did not see her games. She missed plenty of points in completely won positions. We have a lot of food for thought after the event!


In the boy’s section the rating favourite Cristobal Villagra Henriquez (rated 2459)proved better than his opponents and won the title for Chile. Despite the draw in the third round and the loss in fourth he managed to calm down and win five games till the end of the event.
A curious moment happened during the price giving when Cristobal did not show in time to take his trophy. I thought that he is chasing a flight but it appeared that there was a much more important thing to do- he was watching the football match of his compatriots with Brazil…



In this section a pleasant surprise was the second place of Diego Blandon Villa of Columbia. Third was Giuseppe Leiva of Peru.
Both winners of the boys and girls event earned a GM norm. It is Cristobal’s second norm.
Chess in Paraguay is becoming more and more popular these days thanks to the efforts of their best player. GM Axel Bachman recently crossed the 2600+ rating mark. In fact not only crossed but sky-rocketed to the 2652 mark. Axel is a national hero in his country.
Another remarkable person is the third seeded in the boy’s section Guillermo Vazquez. He is good in there things. Chess, where he is an FM, mathematics (he’s heading for Olympics in South Africa after the Panam) and software. I am using the chance to express my gratitude to his parents for the wonderful barbecue evening that they organized for the players of the event. (A blitz tournament with prices also took place then!)
I would also like to thank Ronald Zarza Pelissier for the wonderful organization as well as to all the arbiters and organizers involved in the event.
