Artur Yusupov on Analyzing Your Own Games

Artur Yusupov on Analyzing Your Own Games

 Artur Yusupov on Analyzing Your Own Games

-----------------------------------------------------------------------

Why do I wish to highlight this topic in particular? Well, it is quite possible that my own development as a chess-player has been successful precisely because I have devoted a great deal of time to the analysis of my games. I consider that analysis of one's own games is the main method by which a chess-player can improve, and I am convinced that it is impossible for a player to improve without having a critical understanding of his own games. Of course, this does not mean that one need not concern oneself with other aspects of chess training. It is necessary to study the opening, the endgame and the middlegame; it is extremely useful to study the games of strong players, etc. But by taking our own games as examples we can generally learn rather more.

Our own games are nearer to us than any others. We played them, and we solved the problems which were put in our way. In analysis it is possible to examine and to define more precisely the assessments by which we were guided during the course of the game, and we can establish where we went wrong and where we played inaccurately. Sometimes our opponent punishes us for the mistakes we make, but often they remain unnoticed and may only be brought to light by analysis. So, what do I consider are the important points to pay attention to when you analyze your own games? 

Above all, you need to find the turning- points - to establish where mistakes were made, where the assessment of the position changed, or where an opportunity to change the situation on the board abruptly was not exploited. The ability to find the critical moments of a game during analysis is itself exceptionally important, since this will also help you to track down such moments during actual play. This is perhaps the most difficult aspect of chess - recognizing the critical turning-point in a game, the point when it is necessary to think really hard and to solve a problem; when the outcome of the whole game depends on a single move.

The second point to which you should pay attention when analyzing your games is the search for the reasons for your mistakes. By revealing your mistakes you will gradually come to realize what they might be associated with, and you will see the deficiencies in your game. Of course, it is easier if you have a trainer who can help you. But you will feel the benefit only when you yourself begin to sense the reasons for your mistakes acutely and no longer wish to put up with them. An objective awareness of one's own weaknesses is a necessary first step in the serious business of correcting them.

The third aspect that I wish to mention is that it is very important to look for new possibilities, moves which in the course of the game you paid no attention to because you were fascinated by other ideas. After analysis you begin to get a better feeling for the type of position being studied, you master the strategic and tactical methods which are typical of such positionsAnd the conclusions that you arrive at independently imprint themselves on your memory much more permanently than those obtained from other sources.

A final point. When analyzing a game you have played, you need to give considerable thought to the opening phaseto try to improve on your play, especially if you were not entirely satisfied with the outcome of the opening. By adopting a critical approach to the problems that you faced in the opening it is possible to improve your knowledge, to outline new plans and to think up important novelties.

How to Study Chess Games with the Computer (In-Depth)

How to Study Chess Games with the Computer (In-Depth)

How to Study Chess Games with the Computer (In-Depth)

-----------------------------------------------------------------------------

Improve the Chess Board Visualization (Step 1)

The first step in my recipe is to “scan” the game rather quickly without a chess engine.

You can do this very easily, simply by loading the game (most typically in PGN format) into your favorite chess software, for example LiChess or ChessBase, and use your keyboard arrows to replicate it move after move.

Do this with the engine turned OFF. For example, in LiChess you can toggle off Stockfish analysis just with a click (on a toggle-like button, indeed).

The tricky, but also most important part, is that you must keep your brain AWAKE while doing this. Weak chess players often have the tendency to shut off their brain when they look at the engine’s evaluation. This makes your training process passive, and therefore much less effective.

Instead, you must keep your spider-sense well awake, in particular to spot any moment in the game that rings a bell, or that just seems interesting for some reason.

You can, and should, also keep track of these moments, for example by writing down on a piece of paper the move number, or more simply by adding a comment in the file, like “Interesting moment spotted!”.

What is the purpose of this first, very quick, step in the process of studying a chess game? 

The idea is to work constantly on the board visualization and on your intuition. Strong chess players “feel” the position, which is why they are very strong even at extremely fast time controls.

By simply taking a quick look and making conclusions such as “something is happening right here right now”, you will train your board visualization. Of course, lots of error will happen at the beginning, but don’t worry — keep doing it anyway. Improvement will arrive by repeating the process over and over again.

-----------------------------------------------------------------------

Error checking in a Chess Game (Step 2)

The second step in this chess training plan is to scan again the entire game, and again rather quickly, but this time with a chess engine active.

Your task in this phase will be to take note of the moves that create a strong change in the engine’s evaluation. Watch out to avoid misinterpreting the word “strong change” though!

Amateurs, and in general inexperienced chess players, often make the mistake to consider any change in the evaluation like a blunder of the player. Things can’t be more far from the truth!

In my opinion if your level of play is anywhere below 2300 you can discard every change in the evaluation that is less than 1.00 point. So, for instance, if the evaluation at some point is -0.2 and after the black’s move it becomes +0.2 you might be tempted to conclude that the black players has made a mistake.

This could even be technically true, but it’s irrelevant from all practical points of view. A change in the evaluation of 0.40 is something that you would never spot at the chessboard in a real game.

Chess engines and chess software in general are great tools, but they must be used with grain of salt. Calling “mistake” a move that loses less than half of a pawn if frankly non-sense.

Based on my experience, jumps in evaluation of 1.00 and above are signals that something wrong has actually happened. Strictly speaking about numbers, loosing 1.00 is kind of blundering a pawn, which is something you should definitely watch out for.

So in short, you must take note of all moves that cause a change in evaluation of 1.00 point or more. Again, you can do this on a piece of paper, or simply by adding a comment in the file, like “Stockfish passes from -0.6 to +0.8”.

What is the purpose of this phase, that is scanning the game with the chess engine? The idea is that your eyes will be trained in checking errors made on the board. Mainly classical mistakes such as hanging pieces, or 2-moves combinations that loose material, but chess engines can also detect strategical mistakes, like when the fact of choosing a wrong plan changes the evaluation drastically.

If you iterate this step in the training when studying (a lot of) chess games then your natural instinct will be strengthened in avoiding mistakes and blunders… before they happen!

----------------------------------------------------------------------------------

Training Chess Tactical patterns (Step 3)

The first two steps were somewhat “easy”: you just kept pressing the right-arrow on your keyboard and made the additional effort to keep your brain awake. Which shouldn’t really be called “effort”!

By doing that, you now have a list of positions to analyze. The ones coming from Step 1 are positions that you think are interesting, basically because something caught your attention. The ones coming from Step 2, instead, are interesting because the chess engine tells you something is not quite right.

Now the “hard” work begins, and it will also be the more productive work.

First of all, you have to forget about the game. Yes, just forget about it. Your task now is to focus on each position like if it was a puzzle to solve.

One position after the other in your list, set it up on your chessboard (in the computer is also fine), and study it. Analyzing a chess position is a tough task, but you can start by asking yourself the following questions:

1) What are the main features of White’s position? What about Black’s?

2) What are the main weaknesses of White’s position? And in Black’s camp?

3) Who has the initiative?

4) Is there any counter-play target for the side without the initiative?

5) What plans are available for the two sides?

6) What tactical themes are in the position?

Then, something that I warmly recommend is trying to guess the next move (or the next few moves). As always, the choice of a move must be based on a mix of precise calculation, positional and strategical thinking, and an overall objective. In this sense the above questions should be very useful.

The effort you make to choose a move is like a gym for the brain. You should also set a time limit, for example, a maximum of 5 minutes allowed to choose the move, but within this limit try to focus at the highest peak you can.

When you are ready with your chosen move, compare it with the move chosen in the game. If the two are different then the questions you should ask yourself are the following: Are the two moves pursuing the same objective? If yes, what is the difference in playing one versus the other? If not, what is the other move’s objective? After seeing it, do you think it is any better than your choice?

All of the above must be done with the engine OFF. After you have analyzed the position and made some conclusions with your own brain, then it’s time to turn the engine ON again.

Let the chess engine analyze the position for at the least 60 seconds. Then, new questions to think about arise:

- Look at the top-3 suggestions from the chess engine. Do they have similar evaluations? If yes, then it means several moves are possible in the position. If not, then it means the player has a almost obliged choice, and missing it might bring big troubles.

- Is your move among the top-3 engine’s suggestions? If yes, is it the best among those three? If it’s not the best, why so? What is the difference between the first engine’s choice and your choice? Play a few more moves in both variations (with your move and with the engine’s move) in order to better understand the differences.

- At the previous bullet point you went deeper in two variations. For sure, doing that has pointed out many details that you previously missed, both tactical and strategical. What did you miss? Was it something that you more or less knew in advance, or a complete new light on the position?

This part is probably the toughest of all steps in this recipe. Making your own conclusions about a chess position, BEFORE looking at the chess engine evaluation, requires a lot of effort.

Yet, it’s the most important part of the training because it simulates very closely what you are required to do during a real game. In a tournament game, over a real chessboard, there is no engine that suggests you moves or evaluations, so you have to make your own conclusions. And these conclusions will guide you through the choice of a move.

Training your decisions process is a incredibly valuable part of your overall chess training. In my opinion, the secret is to keep doing it over and over, again and again. Study as many chess games as you can. Maybe group them by the opening. And when you arrive to this Step III then give everything you have to make your own analysis of the position, and then discuss your choices by comparing them with the chess software that you are using.

-------------------------------------------------------------------------

Practice Chess Calculation (Step 4)

Down to the last step! This time you are going to train pure calculation, which is arguably the most important skill in critical moments of the game.

You will start with the list of positions that you got at the end of Step 2, those where a move causes a change equal to or greater than 1.00 point in the chess engine’s evaluation.

For each of these positions, your task is to set it up on the chessboard and start calculating variations! Spend a reasonable amount of time performing your calculation (I suggest between 5 and 10 minutes), while trying to stay as focused as you can.

I warmly recommend to try to put yourself into the tournament mindset, because the ability to focus and concentrate is a skill that you should train too. That means no distractions, no music, no chats.

When you’re done with calculation, you might want to spend 1-2 minute to write down the variations that you calculated, to make sure you don’t mix them up in the upcoming step.

Now you can activate the chess engine for the last time, and your objective is to check each one of the variations that you calculated with the engine. You should really check EACH move in EVERY variation.

The engine will tell you what you missed, and what tactical shots you overlooked. Your ultimate goal should be to have a sort of photographic memory that allows you to quickly spot these patterns and therefore to make less errors in your calculations.

Of course, this is a very difficult objective to achieve. Nevertheless, there is no way other than training, training, and … training! Good luck!

---------------------------------------------------------------------

Conclusions and References

In this post I showed a 4-steps recipe to study every chess game.

I am aware that it’s not a easy training. Actually, it takes a lot of effort, and if you have a full-time job and lots of other commitments (like I do), it may seems impossible at first.

However, I saw that in my case it is possible. In fact, at the beginning it seemed really really hard, but after the first couple of games the process becomes somewhat “easier” (not really :D). As with everything, one simply has to get used to it.

Also, if you keep doing it you will learn a incredible number of things by looking at other people’s games in real depth. You will learn how to spot tactical opportunities and how to quickly recognize if a strategic plan is sound or not, in a given position.

Analyzing your own Games

Analyzing your own Games

Analyzing your own Games

When you think about analyzing your own games, it becomes clear how logical it is that this is the most important and natural way of training.  You are personally involved, you have a deep understanding of the position as you have played the game yourself...This gives depth, but also an insight in to the process of thinking during the playing situation.  That insight is impossible to obtain when you study games by other players.  I therefore recommend that you try to describe, with words, how you thought during the game, mixed with more objective analysis.  Then it will be easier to see what you misjudged during the game.  This is a perfect ground for your training as all aspects of chess are included, even your weaknesses.  With the games as a starting point, you can plan your training and add the knowledge that you lack.

 Chess Training for Budding Champions, Jesper Hall

----------------------------------------------------------------------------------------------

 From a conceptual standpoint, I think the main points to get out of analyzing a game are:

 How did the opening work for me?  Did I understand its basic strategy and the needs of the specific position I obtained?  

 What were the critical moments in the game?  Was my initial middlegame plan appropriate and effective?  At what point should I have changed my plans?  What key tactics were in play and what was overlooked? 

 Why did I make critical errors?  Have I made the same types of mistakes before?  If so, what is the key idea to avoid this in the future? 

The key point in all of this is that you are the one who has to make all the decisions at the chessboard from move one.  You have to put it all together and understand what is in front of you.  The best guide to how you will play in the future is therefore how you have played in the past.  For improving players, it comes down to the simple fact that if you can't fix your own mistakes or recognize important gaps in your knowledge, you will not get any better.  No one can be perfect, but recognizing the truth about our own play, however painful it may be, is the first step on the road to improvement. 

Perhaps the most important realization I have had as part of the game analysis process is that I had failed to use a coherent thinking process in my tournament games.  

Analyzing your own games offers a near-infinite number of ways to improve your chess.

With a database program (free or otherwise), you can explore and analyze how other games in your chosen openings have turned out, focusing on key variations and decision points, and identify model master-level games for further study.  

With a chess-playing programyou can take key middlegame and endgame positions that you've identified in your analysis and play them out.  If you've determined that you lack some specific knowledge that is holding you back from better results, you can find books, videos or other tools to address that.  Naturally, this is where chess trainers can come into the picture as well; good ones will look to use your own games as a guide for your training.  In any event, let your own games be the practical guide to what you need to accomplish most.

--------------------------------------------------------------------------------

Game Analysis for Improvement in Play

An earlier post described my general conception of how game analysis can be used as a method of improving play.  Essentially, the focus is put on one's own games and the lessons drawn from them can then be followed up on most effectively.

So far, while I've certainly benefited by re-examining the openings, tactics and strategies on display in each game, the most significant impact for me, interestingly, has been on the thinking side.  I am being repeatedly exposed to alternative moves that I either could not find or did not originally evaluate properly.  Since I know my own thinking process, this type of analysis has had a direct consequence regarding how I now consider each position in front of me, opening up more possibilities and not limiting me to my self-identified "playing style" or "natural" inclinations.  While I do believe that the concept of a playing style is valid and observable, I am more inclined to reject it as an excuse for choosing obviously inferior moves that do not take advantage of the position.

More specifically, here is a description of the method I've been using for analysis of past games:

 They were all initially analyzed, shortly after being played, as a complete game by Fritz on a reasonable time setting (usually 60s/move). This process catches all of the major tactical ideas and offers some insight into alternative moves beyond simply checking for blunders.  

 The setting for changes in position evaluation (the "threshold" option under complete game analysis) was usually set to 50 centipawns (in other words +/- 0.5 in a numerical positional evaluation).  This is enough of a swing in the position to be worth flagging, while cutting out a lot of what for humans would be meaningless differences.

 The game is loaded into a database program, with Houdini running as the analysis engine.  I also bring up my current personal openings book database so I can compare it to the game.

 I review the game move-by-move.  In the opening phase, I look at the choices made, the implications of alternative choices to the main lines (especially moves by my opponent that are not in my openings book), and evaluate the positional characteristics arising from them.  (This is a fancy way of saying whether I like the position or not.)  The engine is used only infrequently in this part of the game analysis.  This phase helps reinforce and refine my opening knowledge and exposes me to new ideas and areas to explore.

 The main part of the game (i.e. when it no longer follows a database game) is devoted to looking at the ideas contained in game positions and investigating alternative moves.  These alternative moves are considered based on the original Fritz and current Houdini analysis functions.  I have Houdini set to display its current top three alternatives in a position, which offers a good amount of variety.  Alternatives are looked at critically and in order to understand their tactical and strategic ideas, rather than attempting to always find the "best move" and slavishly following engine recommendations.

 The game score is annotated with more detailed commentary on individual move alternatives and key variations, while thoughts on the overall course of the game and its significant lessons are then captured, in this case in an introductory blog post.

This analysis process takes roughly two hours per game for me.  I consider this a reasonable amount of time to spend, especially since the focus is on improving my play, rather than achieving a mastery of deep annotations.

As a final note, there has been a fair amount written publicly on the use of computer analysis by players looking to improve their level of play, a good portion of it negative. My experience has been that computer-assisted analysis is quite valuable and productive, with a great deal of return on the time invested.  One still has to do one's own thinking; that said, having engines point out alternatives, which can then be analyzed and understood, has for me resulted in an improved thinking process.

-----------------------------------------------------------------------------------------

The above material was lifted from an excellent chess blog I check out from time to time. I was very impressed by it and thought I would pass it along...I’m just a casual player but if I ever what to get more serious about improving my game, the ideas here about analyzing one’s own games makes  a lot of sense to me.

How to Study Chess Games with the Computer (Quick Run-Through)

How to Study Chess Games with the Computer (Quick Run-Through)

How to Study Chess Games with the Computer (Quick Run-Through)

-----------------------------------------------------------------------------

In this post I will show to you a common method to study chess games with the help of the computer. Studying games played by strong players is a well known training strategy that helps learning new tactical patterns as well as strategic plans.

By the end of this article you will know what are the steps to follow in order to optimize the time you dedicate to study chess. A clever usage of chess software (engines and database) will lead you to dramatically reduce the time wasted!

So, how to study a chess game with the computer? Here are the steps that you should follow:

1) Go through the entire game once, quite quickly, without stopping to analyze at any particular moment and without using the engine, but taking note of the moments that seem the most interesting.

2) Go through the game again, this time with the engine on. After each move, give to the engine about 30 second to analyze the position and take note of the moments where the evaluation changes significantly.

3) Now, without playing the moves in order, set up on the chessboard each of the positions that you noted at Steps 1 and 2. Spend as much time as you need to figure out what is going on. Why was the next move played? And why did the engine change evaluation (it should mean that there has been a mistake)?

4) Opening study. Go once more through the first 15-20 moves (the exact    number depends on each game). Do you actually know this opening? Compare it with your Opening Repertoire database. Is there any new move that you didn’t know about?

5) Middle-game study. Set up the game’s position where you think that the opening is over. Are you familiar with the structure? Try to guess the plans for both players and then compare it with the plans actually played.

6) Tactical training. Now that you have better understanding of what has happened in the game, take again all positions that you noted at Step 2, and analyze again the mistakes that players have made under the light of the strategic plans you are now aware of. Was a mistake purely tactical? Or was it a strategic misunderstanding of the position?

This is pretty much everything you need to know. However, if the above steps sound a bit too vague still, then read the next post, because I am going to elaborate each of them much more in detail. I will also explain, for each step, what feature of your play is being trained.

Choosing between Active and Passive Defense

Choosing between Active and Passive Defense

Choosing between Active and Passive Defense

----------------------------------------------------------------------------------

When our opponent attacks a weakness in our position, like a pawn, for example, our instinctive reaction is to defend it immediately. We have seen in previous lessons that a defensive piece is a passive piece. In Chapter 1: Assessment of the Position, we learned that once our king has castled into safety, the activity of the pieces plays a decisive role in measuring the outcome of the game. It is very important not to play with a passive piece for too long, or even temporarily.

Imagine a patient going to a doctor with complaints of stomach pain, and the doctor suggests that surgery be done the next day! Is it normal? Shouldn't he have done a thorough and proper diagnosis, prescribed relevant medicines, or even advised the patient to change his food habits? Only as a last resort should he suggest surgery.

In chess, we should see defensive moves as something of a surgery. It should only be done as a last resort. If this is the case, how are we supposed to react when our opponent threatens a pawn in our position, for example? 

1) A strong counter-attack is the best defense. Try to attack something in your opponent's position instead of passively defending.

2) Try to defend yourself indirectly - maintain pressure, using tactical means. If he takes your pawn, he should lose something else.

3) Sacrifice the attacked material in exchange for piece activity, initiative, an attack or positional compensation.

4) Postpone playing a defensive move by at least one move. This is a significant improvement over defending it immediately. 

5) If none of the above work, only then should we defend directly.

Initiative is the essence of any sport. Let us try to understand what we mean by initiative. To make it simple to comprehend, the one who gives threats has the initiative and the one who responds to threats is on the defensive...

What's wrong with playing a defensive move? The defensive piece becomes passive and initiative shifts over to our opponent. His pieces will become active and flourish, while our position will stay passive and cramped. 

Defending passively against every threat is a common problem for many upcoming players. It is essential that they change this defensive mentality to improve in their chess strength. If we analyze deeply why a player plays defensively, we can understand that the root causes are: giving undue importance to material, a "safety first" approach to chess, an unwillingness to take risks, overestimation of the opponent, underestimation of ourselves, lack of trust in our ability to calculate, and fear of making a mistake. These are some of the main causes that makes a player play defensively. To play strong, active chess, we must improve ourselves in the above areas...

We often see in a young player's games a willingness to retreat to defend against threats. Such play should be avoided, unless it's forced. We should move our pieces forward and resist the temptation to defend passively...

In Summary...

1) Try not to play "automatic" defensive moves for every threat made by the opponent. Playing defensively can be seen as a "bad habit".

2) Offence (or counterattack) is the best form of defense in many cases.

3) We should not be lazy to do some complex calculation when it comes to choosing between active or passive defense.

4) We should reject the impulse to defend passively by constantly looking for active moves.

5) Passive pieces lose most of their power while remaining in passive positions; do not condemn a piece to passivity by playing defensive moves.

6) A defensive move usually hands over the initiative to the opponent, so avoid them as mush as possible.

Scanning Technique

Scanning Technique

Scanning Technique

---------------------------------------------------------------------------------------------

Lasker has famously expressed this process, "When you see a good move, look for a better one". This teaches us that there are good-looking moves and there are good moves. Our analysis alone should establish the difference between the two - not our likings or prejudices. We may like to move our pieces around the board in a certain way, and we should analyze these moves first, but this should not be a factor in deciding the final move that is played. It is essential to be as objective as possible without curbing our natural instincts. Not an easy task, but entirely possible!

It also teaches us the importance of the "searching" quality that is required to be a good player. We are constantly searching for the best move, even after we spot moves that appear "logical" or "forced".

Once we have established that our move is not forcedwe first need to survey the options available to us. For this, I strongly suggest employing the "scanning technique" to make a list of possible good-looking moves, what we call "candidate moves".

To employ the scanning technique, first scan the board from the a-file to the h-file, starting with the pieces and then the pawns. Try to find all possible good-looking moves for each piece and make a mental list. Then do the same for all the pawns. Now we have a complete list of all the candidate moves in the position. We can then proceed to follow any of the approaches below:

- Remove bad-looking moves from the list by process of elimination;

- Analyze the most forcing continuations (checks, captures, threats and pawn breaks) to see if they work; or

- Analyze the move you like most and if it looks like it won't work, follow the process of elimination to discard bad ideas or search for the most forcing continuation.

Fundamental Chess: Logical Decision Making,

GM Ramesh RB


What kind of move?

What kind of move?

What kind of move?

---------------------------------------------------------------------------------------------------

Writers use all sorts of fancy names to describe different kinds of moves. In a large game collection, Savielly Tartakower cited more than a dozen types of sacrifice. He gave each type a name, such as 'vacating sacrifice.'

These distinctions may make for entertaining reading. But they aren't very helpful If you try to use them as a checklist during a game - and look for an 'irruptive sacrifice' or a 'rolling up sacrifice,' whatever they are - you'll just waste your time.

However, it is useful to look at the basic kinds of middlegame moves. We can roughly identify four:

(a) Tactical moves. These moves make checks, captures, sacrifices or threats, or they respond to checks and threats. These are forcing or forced moves.

(b) Repositioning moves. They change, and hopefully, improve the placement of one of your pieces or worsen the range of an enemy piece.

(c) Exchanging moves. They offer, initiate or complete an exchange.

(d) Moves that change the pawn structure, that is, moves that are significant advances or captures

Of course, there are some moves that fall into more than one category. A knight advance that makes a threat can be both tactical and repositioning. A recapture of a piece with a pawn will change the pawn structure while completing an exchange.

But the point here is that TMI (too much Information) is a more manageable beast if you appreciate that you are essentially dealing with these four types - not 17 or 23 - and that some of them occur much more often than others.

---------------------------------------------------------------------------------

Which ones occur most often? 

Well, if we think of the middlegame as lasting from roughly move 21 to move 40, statistical surveys of master tournaments show that repositioning moves are the most common. In second place are tactical moves. These are the moves you will be playing most often.

On the other hand, trading moves and changes in the pawn structure are relatively rare because 

(a) you can only swap seven of your pieces in a game and 

(b) once a basic pawn formation is set in the opening, it doesn't change very much. The significance of these moves lies in their permanency. A trade or a pawn push cannot be taken back. And because they so often change the evaluation of the position, they deserve their own method of study.

You can work on your skill at trading and pawn pushes by looking, once more, at master games with a special emphasis. After move 15 you should stop whenever a piece is traded or a pawn is pushed. Don't move on - or click on - until you can explain why the move in question makes sense. If a player initiated the trade, figure out why. Was the trade forced? Does an exchange favor him? Certain players, such as Fischer, Anand and Capablanca never seemed to have bad pieces - because they exchanged a potentially bad one off long before it became bad. Their games deserve your attention.

Blunder-Check

Blunder-Check

Blunder-Check

------------------------------------------------------------------------------------------

You hear this complaint all the time from students:

"When I look at a position I can usually see what the bad moves are. But I have a hard time figuring out which are the good ones. That makes it very difficult to choose a move I can play."

Actually, that should make it easier. It is easier because of the way games are won and lost. Until you are at least 1400 strength - which is about the average for tournament players - most of your games will be decided by blunders. You or your opponent will overlook a threat, leave material en prise, or otherwise turn a reasonable position into a very bad one.

The huge role that bad moves play is a good thing. It provides an obvious way to lose less often: Cut down on your blunders.

This sounds too simple. But it's the truth. 

The longer the game goes on without a major mistake by you, the greater the likelihood that your opponent will commit the first double question mark move and beat himself. How can you cut your blunder rate? This is the one area in which using a checklist does work. A two-question list should be sufficient.

As soon as your opponent makes a move, ask yourself "Did he make a threat?" In the vast majority of cases when a sub-1400 player blunders, he didn't realize there was a threat.

If the answer to the question you ask is "No," there's a pretty good chance your next move will not be a blunder. Even GMs have played double question mark moves because they didn't look for a threat.

-------------------------------------------------------------------------------

Threat detection is largely a matter of learning how to see the board from your opponent's viewpoint. Youngsters are always surprised by how different the position looks if you tum the board around - either an actual board or using the flip switch on a computer.

If you can see the position the way your opponent sees it, you should be able to spot the vast majority of enemy threats. A good way to practice is to look at master games from a database:

Inexperienced players usually find it much easier to spot threats involving the enemy pieces that move along straight lines, such as rooks and bishops. They have a harder time noticing when an opponent is threatening to win with a knight move. GM Kevin Spraggett urges his students to work on this by trying to solve endgame studies that only have knights and pawns.

When there is no threat to overlook, a move can be a blunder only if it changes the position in some (bad) way. Then the task of avoiding a blunder is a matter of visualizing what the board will look like from your opponent's point of view. 

A second method of anti-blunder training is to play practice games against a computer with a special focus. Try to play normally but make a priority of not blundering. This is better than playing a human opponent because humans can overlook your mistakes. Computers are ruthless about punishing them.

Don't be concerned if your overall quality of play suffers a bit, if you feel you're not finding the best moves. Game quality isn't the point. Learning how to avoid blunders is.

The payoff is this: 

If you can eliminate one potential blunder from each game, your playing strength should improve by at least 100 rating points.

When you've reduced your blunder rate - and thereby raised your playing strength - you'll find that you get to play stronger opponents. They will prove harder to defeat because they've already learned how to cut down on their own blunders. They won't beat themselves.

To defeat them you have to refine your move-selection technique. Therefore, it's worth learning more about the different kinds of moves you have to choose from.
