Answers.Body: <p>I'd have to disagree with @andrew about analyzing ones' own games.  The reason is, I'm a B-player. I make B-player moves. I perform B-player analysis. That's insufficient. Spending precious time to produce weak analysis is inefficient.</p>
  
  <p>This may offend people.  But consider - if you had to make a home repair and you didn't know how, would you just figure it out on the spot or would you seek an expert/education to make you smarter? If you needed to shingle your roof, would you just get up there and start hammering? Or would you refer to several how-tos and learn a little first?  Maybe you'd talk to your brother-in-law who's a contractor?</p>
  
  <p>Instead, I start with the engine, on a setting that I cannot beat.  This is analogous to have an instructor or how-to book.</p>
  
  <p>I key the game into the engine and let it analyze each move (both sides.) If the computer produces a move and the score deviates too much (for me, a half a point), I stop to determine <em>why</em> the computer chooses a different move.  Then I work to understand how the computer's move prevents situation the caused by my move.</p>

Answers.Text: Tony, you don't seem to understand one of the most important reasons for analysing yourself first without an engine. If you are a mediocre basketball player you don't say "Oh, there is no point in practising. I will just watch videos of Kobe Bryant because he is so much better than me." When you do your own analysis without the aid of the engine you are doing essential training for your analytical skills. It is active. When you switch on the engine you do nothing for those skills. It is purely passive. Whatever you discover through your own sweat will stick much better than computer analysis.

Answers.Text: I am strongly against using engines. For the simple reason that they use different algorithms for picking moves. B-player analysis may be weak, but you will learn a lot from it, much more than from a game played by two grandmasters. Once you analyze your own game and find a mistake or a stronger move, it will stick. You will recognize the pattern next time you see it on the board. As you pointed - engines suggest how to move but not why. This is their weakest point.

Answers.Body: <p>You have to have a certain degree of ability before you gain <em>a lot</em> from analysing your own games.</p>
  
  <p>Certain points you can discover by yourself, but is it just a move or two, or is your whole plan bad? Often you'll not be able to answer that on your own. You can guess, but your guess isn't likely to be that much more reliable than your play in the original game. You'll learn from your own games faster if you find a stronger player to look at them with you.</p>
  
  <p>If you can't do that and have to do it on your own, here's a suggested program:</p>
  
  <p>Play through the game, observing it like a movie. Don't launch yourself into deep thinks. On this pass you're only looking for obvious tactical blunders, so spend only a couple of seconds looking for ways you could have lost or won material. Note them down somewhere for further analysis later. Reset the board.</p>
  
  <p>Play through the game again, five moves at a time. Every five moves stop and ask yourself which side is better, if any. Mark that evaluation on the sheet. Watch, and when that evaluation changes, somebody made a mistake; go back and look through those five moves to see if you can find it. Maybe you can't, but if you can (and you've found it only if you find an alternative that maintains the evaluation) circle the move that caused the change.</p>
  
  <p>Only after that should you fire up a computer to look at the game. Right now, you're checking your own conclusions against the computer. Walk the computer through the game, comparing its evaluations with your own. If they're different, spend 10 minutes or less finding out why (it's rarely productive to spend more than 10 minutes on things like this). If you can't, mark it and go on.</p>
  
  <p>What you're looking for here is whether your evaluations agree with the machine, and most especially if you <em>and</em> the machine pick the same "turning points" in the game. You're trying to correct your thinking here, train yourself to evaluate positions better.</p>
  
  <p>If, after the end of this exercise you still don't understand the computer's evaluations of some positions, set the position up and play 5-10 games against the computer, starting from that position and taking first one side and then the other from that position and see what happens. Let the computer show you what it sees, and try your ideas against it. Learn to implement the ideas and evaluations you're learning.</p>
  
  <p>But seriously, the best training games to analyse are games by players a couple of classes higher than you. If you're a C/D player, Carlsen's games aren't going to do you a lot of good; that's like a a guitarist that can manage three chords trying to learn from listening to Segovia; improvement is possible, but not all that likely. A D player can much more readily understand how to play like a B player than like a Grandmaster; it's like steps in a stairway.</p>

Answers.Text: +1 good suggestions.  One thing to consider before studying the game of a B player is that B players have many holes in their game, so it's not certain that all of their moves are good ones.  I think it would be more productive to study the games of a GM against a lower rated player to see how the GM takes advantage of sub-par moves.

The crux of the problem in analysing games from a much higher rated person, is the problem of induction, of drawing a general conclusion from a specific set of moves. It's the difference between knowing "what" and knowing "why."

Answers.Body: <p>I think that the point in analysing your games is to point out in what conditions you are inclined to make a mistake (not necessarily a blunder, but also a sub-optimal move).</p>
  
  <p>You do not study your games to improve your chess knowledge (for that you have to study Grand Masters games), but to improve your approach to the game.</p>
  
  <p>Try to determine common situations in your games, give them a name and try to find a kind of behaviour to tackle them.</p>
  
  <p>Just an example:</p>
  
  <p><strong>Unexpected move:</strong> this is when your opponent made a move you did not expect and you notice that you lost confidence and you made a suicidal move to find counterplay. 
  Then in your analysis you find out that your position was not lost at all!
  It was you that reacted badly in that kind of situation. Take note of it.
  The next time this situation arises, try to stay calm and be aware that usually a mistake is followed by a worst one in order to avoid it.</p>
  
  <p>There are hundreds of situations like this that you have to find out yourself.</p>

Answers.Body: <p>Engine analysis can take care of the tactical bloopers, it is usually the strategic plans and more human stuff that is hard to figure out even for strong players, and Andrew's advice should help in that regard. </p>
  
  <p>About the openings however, I believe it was Edmar Mednis who mentioned that 50% of the time should be spent studying openings, and it is not just about memorizing lines but also about the associated motifs extending to the middlegame and possibly into the endgame for openings like the Spanish Exchange and Berlin. Examining opening moves with only an engine can be tricky as the playable candidate moves usually do not differ beyond one-third of a pawn (or roughly thirty centipawns) or even up to half a pawn, which means almost nothing to a human player. Cross checking the main lines with books and games between strong players is definitely more important here.</p>

Answers.Body: <p>Here are my 2 cents in addition to the already well-written answers:</p>
  
  <p>Start your analysis <em>during</em> your games instead of after. It really helps remember the critical points of the game rather than trying to recall them later (you're likely to not immediately start analyzing your game after a round finishes...). This will save you both time and effort. Here's how:</p>
  
  <ol>
  <li><p>Mark moves where you took more time than usual (Do the same for your opponent's moves!).</p></li>
  <li><p>Mark the point where you got out of opening theory (that you knew at that point), and check later with an opening database whether you played the next few moves accurately.</p></li>
  <li><p>Mark the point where you got out of your comfort zone (when did the complications begin? when did your opponent sac a piece on you? etc.).</p></li>
  <li><p>Refrain from giving ?s and !s on the scoresheet during your game (unless you want to use it as a psychological tactic against your opponent).</p></li>
  <li><p>If there was a time when you wanted to attempt a tactical shot, but didn't; mark it as well, so that you can check later for its soundness. (I use an inverted "T" (for Tal) to mark such moves :P )</p></li>
  </ol>
  
  <p>Doing this takes little time, and saves a LOT of time during post game analysis. Good luck!</p>

Answers.Body: <p>All analysis (as Gaul) is divided into three parts:</p>
  
  <ol>
  <li>During and immediately after the game</li>
  <li>Annotation after the game</li>
  <li>Computer engine checking</li>
  </ol>
  
  <p>Step one has been covered fairly well by the above posters, but to reiterate:</p>
  
  <ul>
  <li>As you write the moves, mark moves which took you a long time to make</li>
  <li>If you have space/time write down any variations you are considering</li>
  <li>Write down any moves of your opponent which you feared (especially if they weren't played)</li>
  <li>Always do a post-mortem (preferably with your opponent, or even better, a stronger player) and do it ASAP; write down any new ideas/variations</li>
  </ul>
  
  <p>Step two was also fairly covered but for the sake of being thorough, involves going over your variations and all the work you did during the game, looking for mistakes. </p>
  
  <ul>
  <li>Look at positions where you took a long time and see if you can justify the time taken for the move made.</li>
  <li><p>If you spot tactical combinations which you missed in the game, save the position as FEN (explained below). </p></li>
  <li><p>Look up the opening and if possible, look at middlegame plans for that opening (if you can't find it in a book, look at GM games and try to extrapolate).</p></li>
  <li>Focus on the things that caused you to lose and then learn the info necessary to cure that weakness (e.g you lost a drawn R vs P endgame, learn that endgame; you fell into an opening trap, learn that opening etc.)</li>
  </ul>
  
  <p>Step three is where I think some of the advice falls short. </p>
  
  <ul>
  <li>Computers should not be used to analyze the game, they should be used to analyze your <strong>annotations</strong>. </li>
  </ul>
  
  <p>Essentially the computer is a purely objective machine, if you use it to analyze games it may give you crazy variations which are objectively good but which have you sweating buckets. Instead, you use the computer make sure your analysis is objective (i.e, free of calculation errors, bias, etc.). When the computer analyzes the game you should only use that information to supplement your existing analyses (not replace it). </p>
  
  <ul>
  <li>One other thing that can be done with computers that hasn't been mentioned is <strong>playing "won" positions (from your games) against the engine</strong>. Do it from increasingly smaller margins of victory (up a whole piece, the exchange, two pawns, 1 pawn, 1/2 pawn) and watch as your ability to the convert the point becomes GM-level</li>
  </ul>
  
  <p>EDIT: Forgot to add a few things:</p>
  
  <ul>
  <li>The reason you save the missed tactics as a FEN string is to create an Anki flashcard of that position for subsequent review and memorization. Anki is an extremely powerful tool for drilling those tactics and positions you want to completely memorize</li>
  <li>Don't forget the <strong>point</strong> of analysis which is to <strong>improve your understanding of the game</strong>. Make sure that you have a list of conclusions/"things learned" from every game that you analyze. It seems kind of trivial, but having such things in writing makes them that much more concrete</li>
  </ul>

Answers.Body: <p>Analyzing your own games is the best and fastest way to improve in my opinion.  </p>
  
  <p>As soon as possible after the game, write down the variations that you were thinking about during the game, especially the ones that were not played.  This will be useful when you come back to the game after days, months, or even years.  As you improve, it will be helpful to see what you were thinking during the game.  That way, you can pinpoint how you can improve your thought process in future games.</p>
  
  <p>When you start analyzing, use a chess board, but don't use an engine at first.  Look for moves where you made a mistake or missed something important.  If you lost material, go back and find the moment where you blundered.  If you got into a bad position, try to identify the moves that led to that position and evaluate some alternatives.  Put everything you come up with into your chess program/database (you <em>are</em> using some kind of a database, right?).</p>
  
  <p>After you've gone over the game "by hand" (this should take at least half an hour for a slow game, even more time if it was a complicated position), now it's time to use a chess engine.  Go through all of the moves and take note of where the engine says that you either made a poor move or missed an opportunity for a better move.  Again, add variations to your database.  If it's not clear why something that the engine suggests is good, investigate it further.  Try out some lines and see what the engine says.  </p>
  
  <p>At this point, you have an awful lot of moves in front of you.  Now it's time to try to take away some lessons from the game.  Go back through the game again and decide what specific thing you could have done better.  Did you make a very poor positional move?  Did you blunder material?  Did you neglect development?  Did you put a piece on a bad square?  Asking questions like this will help you in future games during the game.  </p>
  
  <p>The last thing that you can do is to ask a stronger player for help.  Bring all of the information you have to the stronger player and then go through the game once more.  The stronger player can give you suggestions for how to think in certain positions.  Basically, a chess engine can tell you <em>what</em> the right move is, but a stronger player is often needed to tell you <em>why</em> a move is correct.  </p>
  
  <p>You should try to develop your own analysis style as well.  If you are a strong tactical player, try to go through the game without making moves on the board, just analyze in your head.  If you are good at endgames, switch colors and analyze where your opponent went astray in the endgame.  Hopefully analyzing games is fun and not a chore!</p>
  
  <hr />
  
  <p><strong>Additional thoughts</strong></p>
  
  <p>I didn't mention studying the opening moves because that is <em>less</em> important than finding the specific points in the game where you made a mistake.  After you have looked at the game as a whole, studying the opening can often help you as well.  The best way to do this is to look for grandmaster games in the same opening that was played.  Find out what moves are commonly played, and then go through some games of stronger players in order to find good, general plans for the opening.  Try to see where you varied from these plans and determine <em>why</em> you didn't do what the stronger player did.  This is much more important than memorizing moves (although you will probably find that you've memorized many variations just as a matter of course!).</p>

  Analyzing your own games is the best and fastest way to improve in my opinion.
  
  As soon as possible after the game, write down the variations that you were thinking about during the game, especially the ones that were not played. This will be useful when you come back to the game after days, months, or even years. As you improve, it will be helpful to see what you were thinking during the game. That way, you can pinpoint how you can improve your thought process in future games.
  
  When you start analyzing, use a chess board, but don't use an engine at first. Look for moves where you made a mistake or missed something important. If you lost material, go back and find the moment where you blundered. If you got into a bad position, try to identify the moves that led to that position and evaluate some alternatives. Put everything you come up with into your chess program/database (you *are* using some kind of a database, right?).
  
  After you've gone over the game "by hand" (this should take at least half an hour for a slow game, even more time if it was a complicated position), now it's time to use a chess engine. Go through all of the moves and take note of where the engine says that you either made a poor move or missed an opportunity for a better move. Again, add variations to your database. If it's not clear why something that the engine suggests is good, investigate it further. Try out some lines and see what the engine says.
  
  At this point, you have an awful lot of moves in front of you. Now it's time to try to take away some lessons from the game. Go back through the game again and decide what specific thing you could have done better. Did you make a very poor positional move? Did you blunder material? Did you neglect development? Did you put a piece on a bad square? Asking questions like this will help you in future games during the game.
  
  The last thing that you can do is to ask a stronger player for help. Bring all of the information you have to the stronger player and then go through the game once more. The stronger player can give you suggestions for how to think in certain positions. Basically, a chess engine can tell you *what* the right move is, but a stronger player is often needed to tell you *why* a move is correct.
  
  You should try to develop your own analysis style as well. If you are a strong tactical player, try to go through the game without making moves on the board, just analyze in your head. If you are good at endgames, switch colors and analyze where your opponent went astray in the endgame. Hopefully analyzing games is fun and not a chore!

  **Additional thoughts**
  
  I didn't mention studying the opening moves because that is *less* important than finding the specific points in the game where you made a mistake. After you have looked at the game as a whole, studying the opening can often help you as well. The best way to do this is to look for grandmaster games in the same opening that was played. Find out what moves are commonly played, and then go through some games of stronger players in order to find good, general plans for the opening. Try to see where you varied from these plans and determine *why* you didn't do what the stronger player did. This is much more important than memorizing moves (although you will probably find that you've memorized many variations just as a matter of course!).
  
  > **Comments:**
  > **username_20**: The idea of archiving one's own games is intriguing. I can usually remember all the variations I had considered + the entire game I played for up to a week, but after that I forget (I'm a strong tactical player.)  But being able to bring up an old game and apply new ideologies to it would be fascinating.  
  > **username_19**: *"you are using some kind of a database, right?"* I think this would be more useful if phrased like *"if you are not using a database I suggest x,y,z"*  
  > **username_4**: @username_20 old comment, but all games played online on chess.com or lichess are automatically archived and can be mass exported as PGNs.  
  > **username_4**: Nice idea to study without an engine. It's all to tempting to turn it on and immediately see what should've been played.

  I'd have to disagree with @andrew about analyzing ones' own games. The reason is, I'm a B-player. I make B-player moves. I perform B-player analysis. That's insufficient. Spending precious time to produce weak analysis is inefficient.
  
  This may offend people. But consider - if you had to make a home repair and you didn't know how, would you just figure it out on the spot or would you seek an expert/education to make you smarter? If you needed to shingle your roof, would you just get up there and start hammering? Or would you refer to several how-tos and learn a little first? Maybe you'd talk to your brother-in-law who's a contractor?
  
  Instead, I start with the engine, on a setting that I cannot beat. This is analogous to have an instructor or how-to book.
  
  I key the game into the engine and let it analyze each move (both sides.) If the computer produces a move and the score deviates too much (for me, a half a point), I stop to determine *why* the computer chooses a different move. Then I work to understand how the computer's move prevents situation the caused by my move.
  
  > **Comments:**
  > **username_0**: Good points and analogy.  
  > **username_5**: It's a reasonable argument, but you might be interested to know that in the old days, there were no access to engines, but that didn't stop people from analyzing games and writing books (that often no longer withstand scrutiny of current engines). Analyzing your own games is not going to produce the best of analysis at your level, but nevertheless it is an important skill to cultivate.  
  > **username_6**: I am strongly against using engines. For the simple reason that they use different algorithms for picking moves. B-player analysis may be weak, but you will learn a lot from it, much more than from a game played by two grandmasters. Once you analyze your own game and find a mistake or a stronger move, it will stick. You will recognize the pattern next time you see it on the board. As you pointed - engines suggest how to move but not why. This is their weakest point.  
  > **username_2**: @username_6 Figuring our the *why* to the engine's *what* is the lesson.  
  > **username_7**: Allow me another analogy: I am a novice guitar player. People tell me I should do exercises to improve my playing, but I do novice-level exercises. That's insufficient. So I've hired a professional guitar player to do my exercises for me. In chess, the point isn't the quality of the analysis you end up with, but the exercise you get from the process of analyzing.  
  > **username_2**: @username_7, you're missing the point.  I am recommending the learner figure out why the engine chooses what it does.  
  > **username_3**: Tony, you don't seem to understand one of the most important reasons for analysing yourself first without an engine. If you are a mediocre basketball player you don't say "Oh, there is no point in practising. I will just watch videos of Kobe Bryant because he is so much better than me." When you do your own analysis without the aid of the engine you are doing essential training for your analytical skills. It is active. When you switch on the engine you do nothing for those skills. It is purely passive. Whatever you discover through your own sweat will stick much better than computer analysis.  
  > **username_4**: When you analyze yourself without an engine, the analysis may be weak but you still have the benefit of hindsight (how the particular line was played) which wasn't available that moment.

  You have to have a certain degree of ability before you gain *a lot* from analysing your own games.
  
  Certain points you can discover by yourself, but is it just a move or two, or is your whole plan bad? Often you'll not be able to answer that on your own. You can guess, but your guess isn't likely to be that much more reliable than your play in the original game. You'll learn from your own games faster if you find a stronger player to look at them with you.
  
  If you can't do that and have to do it on your own, here's a suggested program:
  
  Play through the game, observing it like a movie. Don't launch yourself into deep thinks. On this pass you're only looking for obvious tactical blunders, so spend only a couple of seconds looking for ways you could have lost or won material. Note them down somewhere for further analysis later. Reset the board.
  
  Play through the game again, five moves at a time. Every five moves stop and ask yourself which side is better, if any. Mark that evaluation on the sheet. Watch, and when that evaluation changes, somebody made a mistake; go back and look through those five moves to see if you can find it. Maybe you can't, but if you can (and you've found it only if you find an alternative that maintains the evaluation) circle the move that caused the change.
  
  Only after that should you fire up a computer to look at the game. Right now, you're checking your own conclusions against the computer. Walk the computer through the game, comparing its evaluations with your own. If they're different, spend 10 minutes or less finding out why (it's rarely productive to spend more than 10 minutes on things like this). If you can't, mark it and go on.
  
  What you're looking for here is whether your evaluations agree with the machine, and most especially if you *and* the machine pick the same "turning points" in the game. You're trying to correct your thinking here, train yourself to evaluate positions better.
  
  If, after the end of this exercise you still don't understand the computer's evaluations of some positions, set the position up and play 5-10 games against the computer, starting from that position and taking first one side and then the other from that position and see what happens. Let the computer show you what it sees, and try your ideas against it. Learn to implement the ideas and evaluations you're learning.
  
  But seriously, the best training games to analyse are games by players a couple of classes higher than you. If you're a C/D player, Carlsen's games aren't going to do you a lot of good; that's like a a guitarist that can manage three chords trying to learn from listening to Segovia; improvement is possible, but not all that likely. A D player can much more readily understand how to play like a B player than like a Grandmaster; it's like steps in a stairway.
  
  > **Comments:**
  > **username_9**: +1 good suggestions.  One thing to consider before studying the game of a B player is that B players have many holes in their game, so it's not certain that all of their moves are good ones.  I think it would be more productive to study the games of a GM against a lower rated player to see how the GM takes advantage of sub-par moves.  
  > **username_8**: In principle, I agree. But even that situation is open to the "mysterious" (to a B player) moves a GM makes, that a B player may have trouble discerning. The crux of the problem in analysing games from a much higher rated person, is the problem of induction, of drawing a general conclusion from a specific set of moves. It's the difference between knowing "what" and knowing "why."  
  > **username_9**: I agree 100%, I think that's probably the single most important reason to get a coach if you really want to improve.

  Game analysis is important (both your own & other people's games).
  I usually use some computer software-I am not great analysing only from a game scoresheet.
  (if so I would try & make sure I had a board setup in front of me-but the computer chess software is very handy).
  I have Fritz9 / Winboard / BabasChess and a variety of chess engines. I usually use these for my game analysis.
  It can also be very helpful to have a chess coach or other good player look over the game with you to get another opinion.
  Game analysis to start with is not easy but like most skills you can get better at it with practice and it can help you learn from your mistakes and successes-good luck with your chess analysis! :-)

  I think that the point in analysing your games is to point out in what conditions you are inclined to make a mistake (not necessarily a blunder, but also a sub-optimal move).
  
  You do not study your games to improve your chess knowledge (for that you have to study Grand Masters games), but to improve your approach to the game.
  
  Try to determine common situations in your games, give them a name and try to find a kind of behaviour to tackle them.
  
  Just an example:
  
  **Unexpected move:** this is when your opponent made a move you did not expect and you notice that you lost confidence and you made a suicidal move to find counterplay.
  Then in your analysis you find out that your position was not lost at all!
  It was you that reacted badly in that kind of situation. Take note of it.
  The next time this situation arises, try to stay calm and be aware that usually a mistake is followed by a worst one in order to avoid it.
  
  There are hundreds of situations like this that you have to find out yourself.
  
  Create **your** kind of chess theory if you want to improve.

  Engine analysis can take care of the tactical bloopers, it is usually the strategic plans and more human stuff that is hard to figure out even for strong players, and username_9's advice should help in that regard.
  
  About the openings however, I believe it was Edmar Mednis who mentioned that 50% of the time should be spent studying openings, and it is not just about memorizing lines but also about the associated motifs extending to the middlegame and possibly into the endgame for openings like the Spanish Exchange and Berlin. Examining opening moves with only an engine can be tricky as the playable candidate moves usually do not differ beyond one-third of a pawn (or roughly thirty centipawns) or even up to half a pawn, which means almost nothing to a human player. Cross checking the main lines with books and games between strong players is definitely more important here.

  I would focus on the "turning points" of the game. That is, I had a good game until I made move X. If, instead, I had made move Y or Z at that point, what would have been the result?
  
  The idea is to discover your mistakes, first the most obvious ones, then the less obvious, and try to avoid them in future games.

  Here are my 2 cents in addition to the already well-written answers:
  
  Start your analysis *during* your games instead of after. It really helps remember the critical points of the game rather than trying to recall them later (you're likely to not immediately start analyzing your game after a round finishes...). This will save you both time and effort. Here's how:
  
  1. Mark moves where you took more time than usual (Do the same for your opponent's moves!).
  2. Mark the point where you got out of opening theory (that you knew at that point), and check later with an opening database whether you played the next few moves accurately.
  3. Mark the point where you got out of your comfort zone (when did the complications begin? when did your opponent sac a piece on you? etc.).
  4. Refrain from giving ?s and !s on the scoresheet during your game (unless you want to use it as a psychological tactic against your opponent).
  5. If there was a time when you wanted to attempt a tactical shot, but didn't; mark it as well, so that you can check later for its soundness. (I use an inverted "T" (for Tal) to mark such moves :P )
  
  Doing this takes little time, and saves a LOT of time during post game analysis. Good luck!
  
  > **Comments:**
  > **username_13**: If playing in an official game (4) and (5) is simply not allowed.  1-3 would only be doable by making use of optionally marking the current clock times on the scoresheet as a means of "marking" a move.  
  > **username_14**: The USCF Rules and FIDE Laws of chess prohibit a player from making any notes whatsoever.  They allow only the following: 1. The move itself, 2. The time on the clock, and 3. The offer of a draw.  That is all; any further notetaking, for any purpose whatsoever, can be taken to constitute analysis, and subject the player to forfeiture of the game. Do NOT apply the advice in this answer, except for 4, which tells you NOT to mark anything else on the scoresheet.

  All analysis (as Gaul) is divided into three parts:
  
  1. During and immediately after the game
  2. Annotation after the game
  3. Computer engine checking
  
  Step one has been covered fairly well by the above posters, but to reiterate:
  
  * As you write the moves, mark moves which took you a long time to make
  * If you have space/time write down any variations you are considering
  * Write down any moves of your opponent which you feared (especially if they weren't played)
  * Always do a post-mortem (preferably with your opponent, or even better, a stronger player) and do it ASAP; write down any new ideas/variations
  
  Step two was also fairly covered but for the sake of being thorough, involves going over your variations and all the work you did during the game, looking for mistakes.
  
  * Look at positions where you took a long time and see if you can justify the time taken for the move made.
  * If you spot tactical combinations which you missed in the game, save the position as FEN (explained below).
  * Look up the opening and if possible, look at middlegame plans for that opening (if you can't find it in a book, look at GM games and try to extrapolate).
  * Focus on the things that caused you to lose and then learn the info necessary to cure that weakness (e.g you lost a drawn R vs P endgame, learn that endgame; you fell into an opening trap, learn that opening etc.)
  
  Step three is where I think some of the advice falls short.
  
  * Computers should not be used to analyze the game, they should be used to analyze your **annotations**.
  
  Essentially the computer is a purely objective machine, if you use it to analyze games it may give you crazy variations which are objectively good but which have you sweating buckets. Instead, you use the computer make sure your analysis is objective (i.e, free of calculation errors, bias, etc.). When the computer analyzes the game you should only use that information to supplement your existing analyses (not replace it).
  
  * One other thing that can be done with computers that hasn't been mentioned is **playing "won" positions (from your games) against the engine**. Do it from increasingly smaller margins of victory (up a whole piece, the exchange, two pawns, 1 pawn, 1/2 pawn) and watch as your ability to the convert the point becomes GM-level
  
  EDIT: Forgot to add a few things:
  
  * The reason you save the missed tactics as a FEN string is to create an Anki flashcard of that position for subsequent review and memorization. Anki is an extremely powerful tool for drilling those tactics and positions you want to completely memorize
  * Don't forget the **point** of analysis which is to **improve your understanding of the game**. Make sure that you have a list of conclusions/"things learned" from every game that you analyze. It seems kind of trivial, but having such things in writing makes them that much more concrete

  For real life :
  
  A. enter the game into computer without engine straight after game, write down all the things you saw and thought that you can remember.
  
  B.enter the game into lichess.org, tell it to auto analyse. cover up the engine's suggestions by pressing one of the menu options on the right hand side.
