Understanding Compensation

I realise that I am overly materialistic as a chess player, and my understanding of compensation is pretty weak. I'm not sure why this is, as when I was younger I enjoyed sacrificing and attacking chess. I guess that my sacrifices were always based on attacking or tactical ideas, and not on positional ideas. I tend to be a pawn grabber who tries to hold on to material. Is it possible to remedy this situation, or is it even necessary?

Of course it is important to fully understand all aspects of the game, and to be able to apply those ideas in your games, but I really have no problem adopting a style of play. And I suppose I am always going to be taking poisoned pawns, or defending against gambits. One gambit that I've never looked at too deeply is the Evan's Gambit, at least not in terms of working out a black repertoire.

As a lazy...oops, sorry, I mean time constrained player, I'm looking for repertoire choices that are easy to understand and not too complex to learn. The only trouble is, cutting corners and taking easy to learn lines can often mean playing inferior positions.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4!?

So white just gives up a pawn? What does white get for it? For the pawn, white will get a lead in development and an attack against some key squares and lines in black's position. The more white wins I see, the harder I find it to choose a line for black to play. When I was young, the Evan's was not considered fully sound and so was not seen around too much. That was changed in the 1990's when Kasparov, among others, started to play it. For players of my generation, it is still difficult to accept it is fully sound, but proving it isn't sound is something else.

4..Bxb4 - It is possible to decline the gambit, though against my nature. 5.c3


The question is, where should the bishop retreat to, a5, c5, e7, d6? Funnily enough, the latter move is the one I have been choosing as a repertoire, 5..Bd6 or the Stoneware Defence. But I have found it difficult to play this system. I have recently seen a game with Nakamura on the white pieces, where black has an extra pawn but can do hardly anything, an excellent example of compensation for a pawn.




Games like this do nothing to inspire me to play this variation. Black grabs a pawn, and then takes a pounding, hoping that white's haymakers don't connect and somehow he emerges a pawn ahead. I think I have to put some work in to find something a little more active.

I recently played games where I underestimated my opponent's compensation, sat back and allowed them to gain more than adequate compensation for a pawn investment.
I was black here against Bill Jordan and expected Bill to take my e4 pawn re-establishing material equality. Instead Bill played 15.Nd5 using his development advantage to create threats. For the rest of the game I was unable to fully develop my queen side, and although we both traded blunders later in the game, I lost the game mainly due to Bill's more active pieces.

Until I understand the concept of compensation for material I will always struggle with positions like this, but playing and thinking about them can only help improve my understanding.

A Day Off in Sao Paulo

I also had a day off which I spent with my lovely wife, Caroline.It isn't often that we get days off together, and chess tournaments seem to be the same. Because as Sao Paulo had a day off, the men's Grand Prix in London and the women's Grand Prix in Ankara were in full swing. The London Grand Prix is struggling through mid tournament and has seen a lot of draws so far. It's a big shame that 2 of the tournament's young stars, Nakamura and Giri,  seem to be in terrible form. However, the tournament leader, Boris Gelfand is only at +2 so a lot could happen yet with 5 rounds still to go.

The women's tournament has created far more exciting chess, with top seeds Muzychuk and Koneru leading the way on 7.5 from 10 games. With just one round to go these 2 lead by half a point from Xue Zhao, and one of these 3 will be the winner. They have all played each other so it is anyone's tournament. In the last round, the most fascinating game to my mind was the continuation of the theoretical duel between Tatiana Kosintseva and Wenjun Ju in the main line of the Sicilian Najdorf. This was an opening that was all the rage when I was young. I remember buying a book on the Najdorf by John Nunn in about 1982 and being enthralled with it. Nunn then revised his book and updated it and when it was published I became disillusioned with the Najdorf and opening theory in general due to the increase in size of the book and the knowledge needed to play this sharp opening.

Before looking at this game, yesterday I set this puzzle:
This was from the game Nedezhda Kosintseva-Vojinovic Gaziantep 2012. What move did black miss here? If black had found the amazing 30..Qe4! white could have resigned. Black threatens 31..Qxg2 mate and if 31.Qxe4, then 31..Rxf1+ leading to mate as well. The Kosintseva twin was lucky that her opponent missed 30..Qe4 and after an eventful rest of the game, it ended in a draw.

After the moves 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Be7 8. Qf3
Qc7 9. O-O-O Nbd7 10. g4 b5 11. Bxf6 Nxf6 12. g5 Nd7 13. f5 a critical position in the Najdorf has arisen.
I remember looking at this position in some detail in my teens and thinking deeply about the options 13..Bxg5, 13..Ne5 and 13..Nc5, the last of which was always seen as the mainline. A couple of years ago, the move 13..O-O appeared, and has proved a favourite of Chinese player Wenjun Ju. She has played it a number of times, including games against both Kosintseva sisters at the Nalchik women's Grand Prix in 2011 and Russian women's legend Alexandra Kosteniuk in a rapid event in 2011.

Nedezhda Kosintseva played very conservatively with 14.fxe6 fxe6 15.Qe3 when confronted with this move and lost. Two days later, Tatiana played more aggressively with 14.Rg1, though black proved to have adequate counterplay and the game ended in a hard fought draw. Kosteniuk followed the same plan as Tatiana, and again the game ended in a hard fought draw. The soundness of the move 13..O-O was given a big boost by its employment by 2700 super GM David Navara earlier this year.

Obviously this line was expected by Tatiana Kosintseva as she came out with the novelty 14.Qh5. The idea seems very simple, trying to prove that 13..O-O is too risky to play and going straight for the black king. The Russian seemed to be in charge of the tactics, and 10 moves later was completely won, with black resigning on move 30. A great attacking game, and perhaps the last time the Chinese player will venture the risky 13..O-O for a while.




I can't remember who said chess is 99% tactics but openings like the Najdorf certainly bring out the truth of this statement. Another opening that does is the King's Gambit which is where the other position from yesterday originated. You see, I had a look at Marin's book, "Beating The Open Games" and after reading the introduction and first chapter on the King's Gambit, decided to look at some games in the King's Gambit. I had just downloaded the latest TWIC, and the only game starting with 1.e4 e5 2.f4, was between 2 club players. However, just because games aren't between top players, it doesn't mean that interesting positions can't be reached and analysed, like the one from yesterday.
White has so many tempting moves, and sometimes when there are a number of choices, it makes it difficult to find the right choice. White here played 16.Neg5, no doubt heading for f7, but perhaps would have struggled if black had taken on g5. The first move which tempted me was 16.Ne5 heading for g6 instead. After 16..Nxe5 17.dxe5 Qe7 I really would have liked to have opened the h-file but I can't see how to do it. White's position looks promising, but no more. So, how about opening the h-file straight away? Black has real problems after 16.Bg5!! as 16..hxg5 loses to 17.h4!, and 16..Ne7 and 16..Qd7 lose to 17.Ne5. So I guess that leaves 16..Nf6, but white can just take 17.Nxf6 leaving black in a hopeless position.

Olympiad heating up

It's just my luck that on such a dramatic day at the Olympiad as yesterday, I should feel ill and not be able to follow any of the action. Saying that, with the time difference here in Australia, I'd have been in bed before all the main action really would have happened. While it's frustrating to have to go to bed half way through a game that you've become engrossed in, I suppose if I was still living in England, then I'd be working while the games were happening.

Australia at the Olympiad:

The Australian men's team have done us proud. Their starting position was 61, but they are currently in 47th place having had a string of good results. In round 8 they beat Ireland with nice wins from Solomon and Illingworth, while they drew with the team from Tajikistan in round 9, though this could have been an even better result had David Smerdon not lost on time in a good position. David's Facebook post says it all:

"Losing on time on move forty when your 2600+ opponent is about to resign...

Wine. Lots of wine." - D. Smerdon

The men should be pretty happy with the way things have gone though. Max Illingworth has been a star on board 4, while the rest of the team (except Alex Wohl who has been having a forgettable tournament and sounds as if he is feeling guilty about it to the team) have been playing respectably well. 

In my opinion, the women have had a tough time of it. They have had some tough pairings for their position, and have done well to stay around the 50th position in which they started. Tonight is another example where the women have a really tough draw against Argentina who are the second highest seeded team in that score group, while Australia are also in the top half of that score group according to seeding. Likewise they got a very tough draw against number 10 seeds Romania earlier in the tournament. Saying that, the women are doing ok, and have all had their moments.

The under 16's will be a little disappointed, though they shouldn't be. Our top team finished in 8th place from a starting rank of 5th. However, in the last round Australia lost to India by 2.5-1.5, while if they would have won 3-1 they would have gained the bronze medals, which shows how close the event was. Australia fielded 3 teams, the other 2 finishing 25th and 30th. It will have been great experience for these kids, and especially working with a Grandmaster coach like David Arutinian.

This amazing video from Chessvibes captures the drama at the end of the big match USA-Russia.

Of course, the main news of the Olympiad was Russia's loss to the American team. With the Russian's seemingly coasting they came up against a team that can be unpredictable. Obviously the USA are strong but they can sometimes disappoint and they can sometimes amaze. Yesterday they amazed, and all the talk on the social networks is of Nakamura's underpromotion. I've felt so ill today that I haven't actually checked it out yet! So USA pull level with Russia, and they are both joined by China and Armenia. The match up of USA-China is an intriguing one where I expect little compromise. These teams play to win, and if they lose it's usually because they push too hard! Meanwhile Russia drop down to play Argentina while Armenia face a resurgent Netherlands. Since Anish Giri arrived the Dutch have turned their Olympiad around and are on the verge on a great result. Giri-Aronian on board 1 is a mouth watering encounter!

In the women's tournament, China hold a 1 point lead from Russia, with a chasing pack a further point down. Having played many of their closest rivals already China face 22 seeds Kazakhstan, while the Russians have a much harder task against Armenia.
