The art of attack
The current job
My work for the next year is cut out for me. First I must master the basic tactics, then I must master the advanced tactics. I have let grandmasters do the job of gathering the exact right positions for me. The work is simply to train every day, first building the basics, and then slowly extend on the basics, while repeating the basics from time to time.
Openings
In the build up to the tournaments I played this summer, I consciously accepted a few holes. I have three new openings in my repertoire, and I totally abandoned all opening preparations. Of course this will lead, and has already led to some weird early losses. For the coming year, I simply accept that, for a few reasons. The first is that I can only spend my time once, and I must plug the biggest holes first. The second is that I have a philosophy about openings, that when I decide to plug the holes related to the openings, I will do so with a minimum amount of effort. I expect tactics to become my forte, if I look how things are going right now, so if I can get my opponents out of book as soon as possible without too many damage, I deprive them from their openings advantage. There are 25 billion possibilities in the first four moves, and I must be able to find a few moves that are both playable and not well known, with the aid of GM Stockfish. The third reason, is that the middlegame is the biggest hole I have to plug. I have some ideas about sitting ducks, the battle of the LoA's and Nimzowitsch, larded with the ideas of GM Smirnov, but I have no complete picture of how I want to conduct a middlegame. When I don't have a clear picture of the middlegame, I cannot choose the right openings that are in accordance with the type of middlegames I want to play. So any opening preparation at this stage might be a waste of time anyway.
Endgames
I have done some serious endgame preparation already. I consciously postpone to harvest the fruits from this study. For the simple reason that mastering the endgames will only bring me another 100 rating points at the most. But no worries, when everything else is done, I will return to the endgames again and reap my rightful fruits. In the mean time, I trust that the spaced repetition of Chessable will prevent the loss of anything I already learned.
The sitting ducks
The slowly moving pieces like the king and the pawns, are the easiest to transform into a target. First you must fixate them so they can't escape, then you must put them under pressure. I call the king and the pawns the sitting ducks of the game. Only the king is a target that is present from the beginning of the game. A weak pawn must be created first.
A target is only a target when there is an attacker. This means, there must be a line of attack between the attacker and the target. Without a line of attack there can't be no attack.
The killbox
I analyzed all 32 mates. I found the following: the nine squares where the opposing king is, are important. I call those squares the killbox. In the art of attack it is called the mating net. I don't bother about terminology. Later is soon enough to make the terms consistent. For now, I use my own terminology, so I will not be restricted by formal considerations.
Every mate comes about with attackers that point into the killbox. If there is no line of attack from an attacker that ends in the killbox, there can't be a mating attack.
My System
I never bothered about time when conducting chess study. But due to my illness lately, I realized that time is not infinite. Albeit my disease is under control, I want to flick in some measures to increase the chance that I will see some results in this life. My System contains a wealth of information. But it took me to read the book two times before I realized that. That there is really a system in My System. That is simply not efficient enough. In this stage of my life, I must let grandmasters do the hard work. In order to make something of My System, I must do the work myself. There is simply no time for decoding the book. So for now, I abandon the book. With pain in my heart.
The art of attack
There is a book though where a grandmaster has already done the job. The art of attack by Vukovic. Although it is a hard read too, there are some pre's. I already studied it in the past globally. Now there is a digital version by Chessable, with contributions of GM Williams, GM Nunn en FM Plichta. Besides that, it is computer checked.
So I ordered a digital copy and started to read. I already smell the sitting duck, the lines of attack and the pivotal points. I'll keep you posted.

[Source: Excelling At Chess Calculation: Capitalizing on Tactical Chances, Jacob Aagaard, Everyman Chess © 2004.]
White played the (approximately) 34th ranked move by GM Stockfish – and won the game. Obviously, that required ‘cooperation’ from his opponent, who apparently lost his cool and couldn’t see through White’s bluff.
What did White play, apparently based on SEEing elementary tactical themes?
What did Black fail to SEE?
Master Aagaard’s lesson:
“You should never trust your opponent blindly.
Force yourself to be more concrete. You cannot SEE a theme and then make assumptions about it. Chess is too complicated for us to guess our way through.”
That is confusing. You ask me to find a tactical move for white that doesn't work?

ReplyDeleteSorry for the confusion.
The tactics DO work (after all, White won a Rook and eventually the game), but it shouldn't have gotten him more than surrendering the initiative to Black. Black failed to SEE why he should have 'cooperated' with White's tactics (at least initially), and so played something else to avoid the tactics.
According to GM Stockfish, White has several promising moves other than the one he played. The idea is to SEE the tactical theme(s) initiated by White, and the consequences of those moves BEFORE committing to them.
I don't really think that White was bluffing. He saw a tactical sequence (which lies close to the surface) and so he followed through with it. Fortunately for him, Black did not SEE what White had NOT seen for Black.
The game continuation was (annotation by Aagaard):
10. Nf7?! "This move is not very good, but it wins the game almost at once. If Black had been able to keep his cool, he would have seen through White's bluff. Correct was 10. O-O!, when Black would not have enough for his pawn." 10...Qe7? 11. Nxh8 Qg7 "Black had probably counted on winning back the knight and thereby gaining compensation, but he was in for a cruel shock." 12. Nf7! "If it works once, it can work again!" 12...Nc5 13. Ne5 "and White managed to win the game a rook up."
"Black should play 10...Kxf7! 11. dxe6+ dxe6 12. Bxb7 (not 12. Qxd8?? Bxg2!! and Black gains a lot of material for the queen) 12...Qxd1+ 13. Kxd1 Rd8+ 14. Nd2 (14. Ke2 Nc5 15. Bc6 hxg3 16. fxg3 Nfe4 is also very tasty for Black) 14...Nc5 15. Bg2 hxg3 16. fxg3 Nfe4 and Black has the initiative."
Let us keep it simple. We fail at the very basics. We shouldn't be bothered by problems like these. If you do three Novotny interferences before breakfast every day like me, it is hard to judge which moves people find hard to find and which are logical to them.

White and Black failed to ‘Remember the goal’: If you’ve seen 10 of them, you’ve seen them all.
This puzzle was from a rated rapid game, but I expected a higher level of skill, given the two players’ ratings. (I have NO ‘feel’ for comparison of lichess rapid versus OTB classical ratings.)
White: emijus −7
7 - inaccuracies
4 - mistakes
3 - blunders
106 - Average centipawn loss
55% Accuracy
Black: The2100 +20
6 - inaccuracies
2 - mistakes
2 - blunders
79 - Average centipawn loss
44% Accuracy
Does the ratings of the players matter in finding appropriate training positions?

Lichess rating = FIDE rating +100 for bad internet chess players

I read somewhere.
FWIW:
DeleteI finally got around to searching the Web for rating comparisons. Here's a link that gives pretty good relative rating comparisons across different chess sites and organizations (Chess.com, lichess.org, FIDE and USCF), with different criteria for various types of chess (different time periods per game).
Chess Ratings Comparisons
Out of curiosity, I used my last USCF Quick rating (1653) to get my approximate FIDE Rapid rating (1725 +/- 105). Given I haven't played any officially rated chess in the last year, I assume I'm on the 'minus' side of that range.
I also compared my USCF Quick rating (1653) to USCF Regular (1748 +/- 100). Somewhat surprisingly, my last USCF Regular (OTB) rating was 1810 - nearly 50 years ago! So (apparently) I'm still playing at approximately the same level rating-wise as 50 years ago.
What an enjoyable way to spend time!!
Is this a more appropriate position for the current training purpose? I’m trying to find the ‘Goldilocks zone’ for adding to my training material file.
ReplyDeleteThe area is vast. You need about 1200 problems. The .best combinations are around 5-7 ply deep. Two preparing moves with their reactions and the final plucking of the fruit. It is not about solving anything. It is about absorbing patterns.
I wouldn't use time to gather the problems myself. I ordered a few grandmasters to do that for me. The final criterium is the frequency of occurrence. Personally, I like errors by two grandmasters and the comment: x was played here. But if he had played y then this combination wins instantly.
400 problems are about the 32 mates. So you don't have to search for a mate in time trouble.
400 problems are about the basic tactical themes and motifs. So you don't need to calculate. You just SEE it.
400 problems are advanced in the sense of "hard to see". Not because they are complex, but because there is something unexpected in them. Those latter will gain you the rating points.
I love Aagaard s games annotations. He argues that we put to much faith in computer analysis of Gm game as to give the move we should play. . Perhaps not germane to your training but an interesting idea. His books the Attacking manual v1 and 2 are his attempt to create a Modern Art of Attack . With a number of positions for deep study. Frankly some is over my head and I view it as a book to keep rereading over the years.
