How to analyze own games efficiently?

@Lucas_LKJ
Go to finished game (preferably rapid or classical game), analysis board, request computer analysis.

Example:

Stockfish will tell your inaccuracies, mistakes, blunders and best moves to replace them.
Activate Stockfish 14+ NNUE if you want to know continuation of Stockfish's move.

Analyze without the engine. Turn on the engine AFTER your own analysis to check if you were wrong / if you missed things.

Is there any great way to analyze own chess games?

Try "Game Self-Analysis:" https://lichess.org/@/CaseyReese/blog/game-self-analysis/LJrWh0Zi

Well this is my method - no idea if best.

(1) Quick post-game analysis immediately after the game using the 'Request Analysis' option, see above.
(2) Download the game as a PGN.
(3) Next day, redo the analysis in depth using Arena/Stockfish, Opening Explorer, Books adding own annotations as I go along. This can also involve leaving the engine running at points where I was very unsure to the direction of play or consider a move I didn't make but invested time on. Sometimes a game will require a separate 'opening study'. I also download appropriate GM games determined from the Opening Explorer - this is a bit scrapy atm.
(4) Add a five-star quality evaluation to the game, as an indication of future worth.
(5) Store 'competed' analysis on a SCID database of all games played.
(6) Use SCID database to detect the direction and areas of improvement giving the statistics.

Not sure of the actual worth of all this but I would have done something similar anyway. I store all my games off-line as most platforms have poor library features.

I am now considering adding another process.

(7) Create and maintain a annotated database of my '100 Best Games', for repeated review and updates.

There is clearly some value in analysing a game, but I am beginning to suspect it's just as important to actually refresh one's memory of the analysis to avoid making the same mistakes twice.

One big drawback of all this is that I actually play far few games giving the 'analysis' overhead. But I am the type of person who enjoys the 'analysis' as much as the games :)

It can be hard to find the time to analyze every single speed chess game thoroughly. For these, I think the Lichess "Learn from your mistakes" tool is not bad at all. Sometimes the mistakes are obvious, other times they are incomprehensible, and a whole lot in between. But you can still learn a lot, tactics-wise.

I am not too concerned with tactical analysis as I spend as much time on puzzles etc. What I am interested in is poor decision making and repeated structural failings, the tricky stuff to improve.

Also note that most if not all tactical failings are due to in-game time constraints.

I prefer move by move analysis with Stockfish, so it shows me the top 3 lines, best 4 moves, and several moves deep. I can see if my move is even desireable 6 moves later, or if it made top 4. Otherwise, some blunders are that you over defended your kindside when you should have launched a queenside counter attack.

Self analysis works for blitz and maybe rapid. But under classical time controls, I use the computer right away, unless I already had suspicions about a certain move.
