Lecture read by the Honored Coach of the USSR in Loo on April 17, 2014 at the coaching seminar
Few people disputes the need and usefulness of the analysis of the playd games. This analysis allows you to find perfect errors, solve scheduled operations of the parties, determine the critical and turning points in the chess battle and as a result of all this to draw conclusions to help further improve the game of the chess player.
I began to engage in this case, fifty years ago, when, after graduating from the Moscow Energy Institute, I was forced to move away from an active game in competitions in view of a large workload engineering work in a very serious OKB. In 1973, I still returned to the chess world, adopting an offer to become one of the coaches of the USSR national teams.
Well, in early 1976, fate gave me a wonderful chance - I began to work tightly with a little Wunderkind from Baku, who in a couple of years he learned the entire chess world. It was Harry Kasparov.
I will not speak further about the details and method of working with this super-depth youth. I will only say that the analysis of the collected parties, both joint and separate, was one of the main forms of its training process.
Clara Kasparova, Harry Kasparov, Vitaly Melik-Karamov and Alexander Nikitin (Vilnius, 1984)
Harry's takeoff fell on the endgame of the chess docking period, when the quality of analytical work depended only on the desire of the chess player to get to the truth, spending time on this a lot of time and strength. Harry has had a huge love of chess from the smallest years and a constant desire to learn how much of their secrets. An analysis of the various kinds of positions that arose at different stages of this wise game, fascinated the boy first, and then a young man in the same extent.
The results of our analyzes were entered by Garick in thick notebooks. I, having time to create in the Central Chess Club (which is in Gogol Boulevard) Perfocartyr, put his tests to his own chapels, who became the first attempt to facilitate the collection and storage of the necessary chess information and, most importantly, the rapid extraction of its perflocarts from its own instances from a large massif on which Specific information was kept for me. In the seventies, the flow of information every year became more and more, and became a real threat to choke in this stream of new parties and analyzes published in books, chess newspapers and magazines, in special issue, etc. Recovered us invasion of computers to the world of chess.
At first, these were primitive gaming modules, unsuitable even for the role of sparring partners of a serious chess player. But the whole world was waiting for computers capable of solving at all chess tasks. Since chess allowed to study the process of playing chess movements, they became a test landfill to work out serious analytical programs intended for use in science, management, in military business and in many other areas of human activity. Analytical programs designed for chess remained not long to wait. True, the first computers only allowed chess profi not to carry a heavy suitcase with them to competence, made by magazines, informants, analytical notebooks, etc., but for the usual work now they were not adapted.
The first my computer was "Atari 1040", to buy which in 1987 I spent b aboutwe have a more part of your fee received at the end of the Seville, the fourth match of two ka. Now I could ride the competition and training charges with a small suitcase, where my computer was packed, in the small hard drive of which all chess information was kept on the trip. I was pleased with this and very coast my computer. Then computers cost us extremely expensive. So, my colleague, returning from Seville, exchanged the same "Atari" to the new "Zhiguli". My "Atari" served me faithfully for five years, while I was in 1992, having stopped the editorial board of the Dutch magazine "New in Chess", I did not buy a computer at a similar time to the processor 386 SL. It was a real laptop that allowed working with the first versions of the "Chess Base" and "Chess Assistant". True, about any advanced forms of work did not allow to think of its weak memory - operational 1.0 megabytes, and the memory of the Winchester 40 megabytes made it possible to use it only as a repository selected by the valuable chess information. I quickly scan writing on paper, all comments of parties and debut analyzes did on the computer and automatically saved in its memory. So the same five years continued until the parameters of my computer friend did not noticeably give up new, more powerful and rapid brothers. The coaching problems that I had to solve were becoming more difficult, my chess information bank demanded a move to a new, more spacious premises, and had a computer to change.
Somehow it is believed that computers are very quickly obsolete, and their long-fledged utility is about two years. I quietly work with my silicone helpers for five years, quickly getting used to them, I recognize their features. They become my friends with whom it is a pity to part. So, if your chess problems are not complicated, then do not rush to part with the aged computers. No wonder they say that an old friend is better than new two.
For the next five years I had a computer on the Pentium 266 processor, allowed to work with serious programs "Chess Base 7.0" and "Fritz 5.0". Their use allowed to feel more confident when analyzing debut schemes. True, the estimates issued by the computers were sometimes very controversial, and I immediately took the rule not to go about them, but to rely on my understanding of the position.
Honored Coach of the USSR, Senor-coach FIDE, International Master Alexander Sergeevich Nikitin
Now I have been closely friendly friends with a laptop of the company "ASUS", the heart of which is the intel (R) Core TM i3 CPU dual-core processor, which is quite sufficient to carry out checked clock frequency (2.4 megaggers); More than sufficient and hard disk capacity (40 gigabytes). I am completely satisfied with his work: both for good accuracy of its estimates and the time of their receipt. Now there are computers that the same results can get twice as fast, but it does not care if I do not like to rush my friend.
I must say that accumulated by me experience with the latest analytical programs, such as "Houdini 4", "Stockfish 4", "Komodo 5" allowed to draw conclusions over which you should think about.
1. No computer can strengthen your game. He can warn against rough mistakes when analyzing and at the end of it (the termination of the analysis is determined by you, again based on your understanding of the position), give a certain amount of information with its purely formal numerical estimates (there are always several of them) that you must check on the basis of Your understanding of the position and, most importantly, comparing with its, "human" assessment, to make the final choice.
2. The leading in the analysis should be a person. It is necessary to firmly assimilate that the computer is a conscientious account, and the thinker and the main thing in finding a chess truth - you.
3. I am ridiculous to see young chess players playing by the master's candidate, but already having powerful computers with quad-core processors. For them, it is like playing a lot of crystal or gold chess, instead of ordinary wooden figures. On such computers, it is good to spend time on complex games like "star wars", etc., but this is already as they say, another song. Dual-core processors are quite sufficient to solve chess problems. Better on saved money to buy good chess books.
Next, I will try to simulate the process of analyzing the chess batch using a computer. To do this, I took the party of old masters, not at all long, not unmistakable, but without coarse zevkov. She was already analyzed by the grandmaster of a 6 years ago grandmaster, and I wanted to see if my more powerful computer would be able to find something new in the lighting of events that took place in this interesting and instructive batch. I note that during the lecture, I, of course, did not show the options longer than 5-6 moves; They are further provided for independent analysis by coaches and students.

Some players will not wait to start a fight without prior maneuvers. True, most of them rating barely quit for 2100 - for this it is enough to see the sample of parties from megabase. I operate in my comments by examples of the game of stronger chess players who can penetrate the position, expressing the computer language, on b about we have a depth and for less time.
The loss of castling here cannot have serious consequences, as the position in the center is stable. In the meantime, it is stable, the E5 pawn provides a white spatial advantage, and black inconvenience associated with close in their own home, part of which is shot by the enemy. I want to somehow remove this pawn, but not particularly decisive scares the autopsy of the game and the threat of your own king. This is how the conflict of interest is immediately tied and chess Maidan arises.
Serious players prefer to get a small positional advantage, but not lose the casting. 10.BD2. (+0,10) BXD2 + 11.QXD2 QB4 12.RC1 QXD2 + 13.KXD2 NB6 14.B3 Ke7 15.H4 BD7 16.RH3 NB4 17.BB1 A5 18.A3 + / \u003d, Cerez - Flores, 1939.
10...0-0?! (+1,15)
Rudolf Spielman in his scarce comments awarded the only question mark to the castling of the Black King and called this natural course of a decisive mistake that admits the standard victim of an elephant on H7. Indeed, he was not mistaken, speaking mistakes, there are moves and better made by him. The casting of the black at the moment is a move in which there is a lot of provocations, because a less-experienced player immediately lights the eyes at the sight of H7 pawns. "Beat or beat?" - immediately arises an ancient question.
Let's first consult with computers. My computer assistants are "Stockfish 4" and solid "Komodo 5", as I expected, were not united in an express assessment of the consequences of the seductive victim of the elephant. Stokefish decided to sacrifice instantly (11.BXH7 +), immediately giving her powerful support "+1.21". The Komodo did not notice this move at all, in comparison with the solid stuffing 11.Be3 and two similar moves given to me to choose from. I decided to give them time to work. Only after 15 minutes, reaching the depth of the calculation of 25 dossies, the commodo deigned to see the victim of the elephant and its benefits, immediately putting the course to the first line with the estimate "+0.79". At the same time, he indicated the variant evidence more convincing than his competitor Stockfisher. Next, I decided to see, at what depth of calculating the computer will stop moving on. After the hour of work, they dramatically slow the speed of their calculations, and to continue their operation further did not make sense. I had to fix such results of their work: "Stockfish 4" reached a depth of 31 seaside and retained the former enthusiastic attitude towards the victim of an elephant when evaluating the course of the second line (11.A3), also quite high (+ 1.05). Komodo 5 was more thoughtful. It reached the depth of the calculation of 26 dips and retained a respectful attitude towards the victim of the elephant, leaving it on the first line (+0.88), away from the second-mining (11.Be3 rating +0.31). At the same time, it is worth noting that the best "human" course found by nannet (11.NF4) was not awarded the attention of analysts-bills.
Having learned the view of the computer, we will continue our purely chess parsing. The main debut idea of \u200b\u200bFrench protection lies in the undermining of whites of whites in the center. Since the d4 pawning undermining is successfully reflected, black should be hurrying with an E5 pawn, unpleasantly shining movement of black figures. This goal is the extension of the F7-F6 pawn, which needs to be carried out as quickly as possible.
1) 10 ... F5?(+0.90) A fundamental error that does not require variant evidence. Black refuse to undermine the foot center and should now tolerate naughty in the constrained position without counterparts. Hands make the first moves of the winning plan, giving a relax head: 11.H4 0-0 12.RH3 H6 13.RG3 KH8 14.Be3.
Computers that follow my moves give here a cruel assessment of such a debut strategy of black: "+2.04 or + -". I agree and stop further analysis.
2) 10 ... F6 (0.56)
We look again how "stockfish4" works: 1 minute - the depth of calculation of 20 dossies, the estimate of the position "+0.58"; 2 minutes - 22 days and "+0.08"; 6 minutes - 26 dossies and score "0.00".
11.NF4 (11.exf6 (-0.10) NXF6 12.BF4 0-0 13.QB1 BE7 14.A3 BD7 \u003d) 11 ... FXE5 (11 ... ndxe5?! 12.dxe5 FXE5 13.NH5 0- 0 14.Be3 QD8 15.NG3 H6 16.H4 BD6 17.RH3 E4 18.NXE4 DXE4 19.BXE4 +/-) 12.Nxe6!? G6 (looks extremely suspicious, but the best is not visible) 13.dxe5 NDXE5 14.Be3 QA5 15.NXE5 NXE5 white, it seems to be correctly, but their hopes for the advantage seems to be melted. 16.A3 (16.nd4 0-0 17.Be2 NC4 \u003d) 16 ... BXE6 17.AXB4 QXB4 18.BD4 BG4! 19.QA4 + QXA4 20.RXA4 RC8 21.BB5 + ND7 22.Bc3 A6 23.BXA6 BXA6 24.RXG4 0-0 25.RD4 NF6 26.F3 NE4 \u003d.
3) 10 ... be7! (0.00) Elephant made his business - an elephant can go closer to the king. 11.A3 F6! (As an example of an unsuccessful decoupling of the debut for black, I bring a fragment of the party of two great classics, which played this party at the end of his chess career. For some reason, black for some reason immediately went into a deaf passive and died badly. 11 ... NF8? 12.B4 BD7 13.Be3 ND8 14.NC3 A5 15.NA4 QA7 16.B5 B6 + - (Alehin - Kapablanca, 1938) 17.H4! F5 18.RH3 H6 19.RG3 + -) 12.NF4 FXE5 13.NXE6 BF6. Debut development is suddenly interrupted by the beginning of the battle in the center of the board. 14.Qe2 E4 15.BF4 NDE5! 16.DXE5 BXE6 17.exf6 0-0! 18.NG5 RXF6 19.NXE6 EXD3.
At this acute position, checking the work of the "stockfish4" invoice in a single-processor stationary computer was started. One minute, the engine reached the depth of the calculation of 18 dips; Ten minutes later he was at a depth of 27 dips with the stroke rating of 20.Qg4 "+0.14". After another 20 minutes, he stopped at a depth of 31 visits with an assessment of the same movement "0.00".
20.Qg4 RG6 21.NG5 QXB2 22.RE1 D2. Computers give here an estimate "\u003d". But for me, the position is not so clear - it's too difficult to understand what is happening here, and I put an evaluation "unclear." However, if you continue the option - 23.RD1 H6 24.H4 HXG5 25.HXG5 RE8 26.KG1 QC2 27.RXD2 RE1 + 28.KH2 NE5 29.QH3 RXH1 + 30.KXH1 QE4 31.QC8 + KH7 32.QH3 +, then the Eternal Shah is obtained.
11.BXH7 + (+1.15)
White hurry, maybe it's not in vain. After all, the next move is one of the black pawns - F7 or H7 can go to the 6th row, and then the possibility of the victim of the elephant will become irrelevant. Of course, the hand still stretches to "clap" on the H7, after which the White Queen breaks into the fortress, where the enemy king hides, and this has to be fleeting. It was this circumstance that allowed a large fan to interture to consider the victim of an elephant justified, for he believed in his ability to lead the attack and believed that "further attacking opportunities would be automatically found. Donating the elephant, I was convinced that my attack should somehow lead to victory. "
However, not all so simple. The position of black is unpleasant by the fact that their figures are located in some unrest, interfere with organize a counterpore. Using this, white can look for a way to strengthen the attacking group. And then it is not difficult to pay attention to the horse jump E2.
11.NF4! (+0.90). This calm strengthening of the attacking potential was found by the grandmaster Nannom, who did not believe in the effectiveness of the victim of a white elephant, figures, by the way, very useful when attacking the king. If the attack chooses, the absence of looking behind white fields can create them serious problems.
a)11 ... F6 12.NXE6 FXE5 (12 ... RE8 13.NF4 FXE5 14.NXD5 + -) 13.dxe5 NDXE5 14.BXH7 + KXH7 15.NXF8 + BXF8 16.NXE5 NXE5 17.QH5 + KG8 18.QXE5 + -;

Nanna's move "showed" his account, when after 12 minutes of the settlement work he did not highlight it on the monitor, and the favorite remained a stroke made by a spielman, with an assessment that had reached "+1.27". On such a "kick", the computer responded positively, but without delight, giving an estimate "+0.94" after 8 minutes of calculation at a depth of 25 dossies.
11 ... KXH7 12.NG5 + KG8
The party is instantly ended in the case of king ribs - 12 ... kg6 ?? 13. QD3 + F5 14. NF4 +! KXG5 15.QG3 + KH6 18.QG6 #.
13.Qd3! (+1.03) RE8 14.QH7 + KF8
The first phase of the White attack ended. Now they need to choose from several very seductive continuations. Protecting the black king is practically no one, the only transshipment point - the E7 field is a saving loophole for the continuous flight of the monarch, if it succeeds. On the other hand, only two white figures participate in the attack. But this couple is good only for king's maturity in the area of \u200b\u200bthe F7 item. White solve the problem of this item, but not the best way.
15.QH8 +?(-0.16)
It is impossible to say that this failure is obvious. However, this is really a failure. White queen took up not the case. Troubled pursuit, he drives the enemy king from the danger zone into relative safe temporary refuge on the D8, where the path is coming to safer to B8. In the award, he will get two unfortunate pawns of the royal flank and the liberation of the road for a white passage in the queen.
However, further we will see the discrepancy of the winner's approval: "The idea that every victim should be calculated with the highest possible accuracy, fundamentally incorrect. When attacking only faith is required to position (?) And in itself," With the conclusions of a thorough analysis, which proves that here white passed past two significantly more efficient continuations of attack.
First of all, it should be noted that an attempt to immediately play the sake of the attack figure 15. A3 exposes the defect in the white position - weakening the pawns D4. This circumstance can be used black with great benefits - 15 ... NXD4! 16.AXB4 QB5!, And after the forced fastener of queens, white remain without pawns and without initiative.
Discussed a bad opportunity, let's talk about good.
1) 15.QH5!? The winner, quite satisfied with the victory, does not even mention a different version of the scenario invented by him when white get to the F7's pawns before. This time saving sharply enhances the attack, making it irresistible, for example: 15 ... G6 (+2.20) 16.QH7 Ke7 (16 ... ND8 17.NE4 !! + -) 17.QXF7 + KD8 18.NXE6 + RXE6 19. Qxe6 QB5 20.Be3 + - or 15 ... ND8 (1.09) 16.A3 QA6 17.Be3 Ke7 18.RC1 BA5 19.QH7! RF8 20.H4! NC6 21.QXG7 BB6 22.KE1! Ke8 23.RH3! + - QD3 24.H5 BXD4 25.BXD4 + -.
2) 15.NF3! (+1.27). Horse, jumping back, not enough that he strengthened the protection of the central pawn, he, most importantly, gave the road to Elephant, and his appearance on the G5 field threatens to immediately end the battle.
Computers do not immediately realize the power of this maneuver, and approximately half a minute I see their outrage. Their favorite (15.QH5) was shifted from the first line only at the depth of calculation of 25 dossies, and immediately with an estimate of the horse jump "+1.90", and after calculating 27 diligents, the assessment reached "+2.16".
This combination of protection of the D4 pawns and attacks, with the connection to the case of a black-ranged elephant, did not even see Nann. 15 ... F6 16.BH6! Ke7 17.QXG7 + KD8 18.EXF6 BF8 19.QG6 BXH6 20.QXH6 QXB2 21.re1 KC7 22.F7 RE7 (22 ... RF8 23.NG5 ND8 24.H4 B6 25.NF4 BA6 + 26.KG1 KB7 27.NFXE6 NXE6 28.QXE6 + -) 23.F8Q NXF8 24.QXF8 B6 25.kg1 KB7 26.H4 E5 27.QF6 RE6 28.QG7 + RE7 29.QG5 EXD4 30.NFXD4 RD7 31.QF6 + -
15... Ke7 16.QXG7 (0.00) 16 ...KD8 (+0.30)
Black was worth protecting the pawn: 16 ... Rf8 17.nxe6! "So far, my opponent pondered his move, I am deep in the position and decided that this victim wins immediately." R. Spielman. Sorry, grandmaster did not lead a variant evidence of deep penetration. Nann, however, somehow casually notes that the winner simply did not worry about the calculation of the options and rely on his intuition. And in vain ... something is not visible to win immediately, except that only in the case of 17 ... kxe6? 18.NF4 + KE7 NXD5 +. To the introduction of equality only indicated by the company 17 … Ke8 18.NXF8 NXF8 19.Be3 NG6 20.QH7 BF5. Accounts mumble about a small white initiative, and I agree with them.
17.QXF7? (-1.11)
Moving temporary calm has to reflections. I want to look at the position of "Human", throwing in the direction of the sheet with computer counts. Something is not entirely, but maybe it turned out at all. The game on the mat bloody, and now for them the most important thing - push the pawn as far as possible, but where?
Find the strengthening of the White Nannet attack was the old method. This position, he considered the first intermediate result of the victim of an elephant on H7. Then there was a legal question: "What did it achieve whites for these six moves?" Yes, they received for a donated elephant sufficient honest equivalent. But not miserable pawns were their goal when they started the attack. King killed in the center, where he was under the protection of the black figures already standing there. Well, what about it? The threat of taking the e6 pawns is easy to reflect easily, at least putting a horse on the F8, and in its place to withdraw an elephant, even more strengthening the defense of the king. It is not difficult to understand that the two white figures, the "ragged" royal fortress requires reinforcement to continue the offensive. But the introduction into the battle of the reserves is required (approximately 3-4 strokes), and for this short temporary cut, black will have time to withdraw the flare on C8, the king to hide on the B8, and will be ready to start their game. It turns out that it is not so great to achieve white in the attack. In a practical game of these general considerations and arguments, it is enough to question the correctness of the victim of the elephant. And it forced the English grandmaster to start looking for a strengthening for whites, returning to the position that arose after ten moves. So he found a move 11.NF4!
Let's return to the position on the last chart. The assessment of it is completely unclear. White stands only to strengthen the way 17.Be3 (+0.30) BE7 18.B3, and then a rapid game begins on counter courses: 18 ... A5 19.H4 A4 20.B4! QXB4 21.NXF7 + KC7 22.RC1. White passage looks frightened, and many would have moved to the side of white, but the computers are here in their elements. They somehow manage to save black and at 22 ... NB6, and even at 22 ... b6. The further illustrative options given - excellent food for lovers to prove the generally accepted chess axioma "any long version contains an error."
By the way, this is everyday statement impregnated by tears of many chess analysts who were fond of long analytical studies. Practices want to know, and how long the options should be when the probability of error must be large, and that in this case it is considered an error. As for the length of the option, again, the city of Kasparov believes that "in complex positions, the tree of options (notice," tree ", and not only one barrel) is usually traced (them!) To the depth of up to ten dips, which is quite reliable depth . In a practical party it is important to understand when it is necessary to stop the settlement work. Typically, this moment comes when you come to a certain estimate of the position (again, based on your chess force), or when to continue the calculation ... no time. "
Well, an error in the embodiment, due to which all the calculated work turns out to be a waste of time, it may not necessarily be a rude view of a strong response of the enemy, but also the presence of a pair of side branches from the trunk, guiding the game with ways with completely obscure consequences. How many times they bought lovers to follow the computer road (at least from time saving). Even such a chess monster, as V. L. Corrun, said that he did not like to analyze with a computer, since he leads him for some time, and then suddenly changes the estimate of the position, and it had to start all over again.

It seems that the last move made by the spielman gives black more opportunities in the fight for the initiative.
18.H4 BD7 (-0.42)
19.Be3 (-0.85).
In appearance, a useful stuffing move, but it had to be done on the move later, then the White was able to save an important pace, which allowed them to consolidate the position: 19.H5 QA6! 20.Be3! KC7 21.A3 RAC8. Although the position still remained more promising for black: 22.RD1 ND8 23.QF3 BE7 24.H6 KB8 25.H7 ng6 \u003d / +.
19 ... RC8? (0.00)
Immediately and you can not say that it is a mistake, but in fact black do how natural, so late in this situation, when the swift promotion of the white passage it was necessary to oppose the same rapid deployment of active consiprigra. In this party, the black was not silent in the understanding of the position, and to his misses should be tolerant. The grandmaster was in my opinion, in full confidence that everything goes according to plan, and therefore at some moments weakened vigilance, being confident that everything would be fine. The analysis proves that the work of the roam of black is missed about the rest of the big advantage given to them, whom they did not deserve and which was achieved by the immediate beginning of counter-production at the Ferzian flank.
19 ... be7! (-0.95) This is the strengthening of the protection of the king, and the attack on the pawn B2. White is already difficult to give a good advice. 20.H5 (20.B3 QA6! 21.H5 NB4! 22.RC1 (22.H6 NC2 23.RC1 RC8 24.QF4 BB5 25.kg1 NXE3 26.RXC8 + KXC8 27.NC3 BXG5 28.QXG5 NF5 29.NXB5 QXB5 30.H7 NXH7 31.RXH7 NXD4 32.QG7 KB8 - +) 22 ...

Black do not think about activity, but customize the shapes closer to the king. Now it is called a "dense" game. A serious battle of three results flashed at 20 ... Qa6 21.H6 NE7. However, with proper protection, everything ended with the world: 22.H7 NXH7 23.NXH7 RC2 24.NF6 QXE2 + 25.KG1 BD2 26.BXD2 QXD2 27.RF1 RC1 28.G3 RXF1 + 29.KXF1 QXD4 30.NXE8 BXE8 31.QXE6 (31.

White already out of danger of loss. However, they hardly thought about this joyful moment and, not noticing the dangers who threatened them, continued to play victory, introducing the reserve in battle. Equality after 21.H6 QA6 22.H7 NXH7 23.NXH7 RC2 was already considered. The equality ended with an acute struggle at 21.kg1 NF5 22.H6 BE7 23.H7 NXH7 24.RXH7 RF8 25.QH5 QXB2 26.RD1 NXE3 27.FXE3 QA3 28.KH2 QXE3 29.NF7 + KC7 30.RC1 + KB8.

Here and the help of white arrived. The same has affected the difference in the class, especially since black was in stunt. They admit, indeed, a decisive error at the moment when the outcome of the sink battle continued to remain unclear. Well, with such a set of misses loses the one who is mistaken by the latter.
After 23 ... BE7 (0.00) 24.H7 NXH7 25.NXE6 + BXE6 26.NXE6 + KD7 27.nf4 QB5 + 28.kg1 NG5 It was impossible to talk about someone's advantage in position, full of life: 29.A4 QXB2 30.QXD5 + KC7 31.QA2 QXA2 32.RXA2 KD7 33.KF2 RC4 34.KE2 REC8 \u003d.
Now you can already have an unparalleled art of the attack of the famous Corrif of the past. And I remember the Great Kudesman Mikhail Tal and his attacks - these were miracles!
24.KG1 RC7 25.H7 RXF7 26.NXF7 + KC8 27.H8Q
Black fit to give up, what they did through a dozen not at all mandatory moves.
So, what should be left in memory, viewing this interesting and instructive party?
1. The debut version from 10.kf1 is quite suitable for use of complications to fans, and for both colors. In case it is scheduled for its inclusion in a combat debut repertoire, it is worthwhile to record the "right" continuation of the game after the 10th stroke.
2. If you are going to sacrifice a serious material, then the solution must be accepted only after calculating the necessary options for an acceptable depth, which depends on the practical force of the player.
3. "If you do not manage to quickly find an excuse for the idea of \u200b\u200bthe victim, removing all the ambiguities, then you should look for another, more reliable continuation, not a worsening position." (NAN). It will be practical if, seeing the idea of \u200b\u200bthe victim, before it is calculated, first find this spare continuation.
4. Try to keep the situation under control and notice the slightest changes in the position of the position after each course, both your own and, especially someone else's. They can make you make adjustments to the choice of stroke.
5. When analyzing the party, respect the work of the computer that protects you from gross mistakes. But remember that the main thing in the analytical work is a person, i.e. you. And you only need to make the final choice of stroke. And it is not necessary that it will be a computer course of the first string.
6. First, it is worth checking on the computer that you consider the best on the basis of your understanding of the position and style of the game, and then compare it with the best choice of comp. After that, make the final choice.
7. Do not force the computer to give you advice at the pace, for it can give you an erroneous course. In principled positions, give a computer to think at least 3 minutes over each move. Always try to start such an analysis with an assessment of the position, based on general considerations and your positional understanding.
8. Always try to start a computer analysis of any position, with its assessment from general considerations and by virtue of your positional understanding. No analytical program will teach you to understand the position. She will only give you materials for reflection. No even the most powerful computer will strengthen your game if you have a weak sense of position.
Let's teach you chess wisdom only good books. But about this conversation is special.

To write this program I am advised by my once favorite Chess.com's favorite chess site. My account allowed there only a "deep" analysis of my parties (2-3 minutes per batch), and not "maximum" (4-6 minutes per party). In any case, computer analysis on chess.com is slow, as it does not use the Stokefish engine, and its implementation on the translated language of Java script. Thus, the results of the analysis of parties received on the website of Chess.com, often unsatisfactory. Comparison of the results of the analysis of parties on the CHESS.COM website and the local analysis of the Binary Stokefish is far from the first.
It is curious that immediately after publishing this program, my account on Chess.com was closed without any explanation and return of the annual membership fee! (I had to claim him later). Is my program really inflicted them serious financial damage? I would have dineded at their place to earn money on a poor-quality analysis of chess games (made in addition to the Stokefish free chess engine!) And impose a limit on the time of analysis of the party depending on the monetary amount made for membership. It remains only to wish chess.com success in their desire for a "honest" game!
In addition, the analysis is similar to Cheskomovsky, simply does not exist or really does not work in chess programs under Windows. In "Scid VS. PC" it is not, and in the ChessBase "Deep Analysis" does not work at all! I wonder what the developers think about this?
Therefore, I decided to write my own analyzer of chess games, similar to Cheskovsky, only much more quickly, easy to install and convenient in configuration and use.
Functional analyzer of chess games "Creative"

- Ability to use your classification file by specifying it as the ECO_FILE parameter value
- Support Fisher Chess (Chess 960). Chesbaza reads them correctly, and SCID VS PC gives errors - does not support.
So, my program is a cantilever application under MS Windows. Party analysis results can be seen on the screen immediately, but more conveniently view them in a graphic chess application that can read PGN files, for example, in Chessbase or.
The program comes with a free Stockfish engine, the strongest today. You can also configure the application for the use of commercial engines, such as a commodo or guestbie (not supplied with the program), as well as any other favorite chess engine compatible with UCI.
During the batch analysis, the following information is displayed on the screen:
- program name, its version and developer
- party headlines (tags)
- the name of the chess engine and the names of its developers,
- the number of streams and the size of the Hash engine in MB,
- tracks with position assessment, analysis depth and comments.
Each default course is accompanied by an assessment of the position and depth of the calculation. If the difference between the rating of the best stroke and the course made in the game, more than certain threshold values, the comment is displayed about inaccuracies, error or zowka. The best course and continuation are also indicated in the form of a variation. At the end of the variation reported on the assessment of the best stroke, the depth of the calculation, the number of nodes in the MU and the speed of analysis in MU / s. If the engine sees the mat, then the moves leading to the mat will also be shown.
When the difference in the assessment of the positions of the parties exceeds one pawn, incentive comments are included. If the move coincides with the best move of the engine, then congratulations are displayed. If the difference in the assessment between the best move and made in the party does not exceed 0.2 pawns, it is reported good and better continuation. Incentive annotations are characterized by their tone, depending on whether the side wins, or the contrary loses.
Analysis results are stored in a new PGN file, the name of which consists of the name of the source PGN file and suffix "-proanalized_<движком>"(or" -AnalyZED_BY_
After the analysis is completed, the results will automatically be displayed in the graphic chess application for PGN files by default, for example, in Chessbase, SCID VS PC, or any other that understands the PGN format.

Stockfish 10 (latest developers assemblies)
The analyzer of chess games comes together in the Free Stokefish chess engine, which today is the strongest. It consists of four binary files:
- stockfish_10_32bit.exe - for the 32-bit Vindos version
- stockfish_10_x64.exe - for the 64-bit version of Windows
- stockfish_10_x64_modern.exe - for the 64-bit version of Windows operating on a computer with a processor supporting POPCNT instructions
- stockfish_10_x64_bmi2.exe - For the 64-bit version of Windows operating on a computer with a processor supporting BMI2 instructions
By default, the chess analyzer will automatically select an optimal binary file.
With a huge number of servers where you can play online with a "alive" opponent - from PlayChess.com to chess.rc-mir.com or chesshotel.ru (yes Legion them), find a web-interface to a decent chess "engine" is not easy, cavity I managed to go on just that:
1. Play chess online with "engine" shredder:
P.S. According to a professional, to the strength of the real snorkeleton, online engine has a little relationship :)
2. Play chess online with "Rybka" Rybka:

P.S. It seems that the second gluchic script - stably hangs after several moves.
