For instance, let me analyse one of your recent games and show you how you can take valuable lessons from it.
Move 9.b3 is weakning the dark squares on the queenside. b3 doesn't accomplish much as your c4 pawn was already defended, being able to recapture on c4 with a pawn is not worth creating massive dark square holes on the queenside, especially since his dark square bishop can park there (Ba3 for instance would control the c1 square where your rook wants to go).
On move 12 you played Ne4 because you didn't see that your bishop is attacking c7 and that your rook is also X raying c7. 12.cxd5 followed by 13.Rxc7 would win a pawn and also cxd5 in general would open up the file for your rook. As long as the c file is closed, your rook isn't really doing anything. Combination of playing both Rc1 and b3 is really weird because either you want to open the c file or you want to recapture on c4 with a pawn.
For the couple of later moves you didn't play cxd5 to open up the rook which I would have played.
13.Bf3 takes away the retrating square from the knight which makes you vulnerable to 13..f6 14.Ng4 Bxf4 15.exf4 The lesson is pay attention when you block the retreat squares of your pieces and pay attention to how your pieces can get attacked.
On move 18 you missed a 4 move tactic. When analysing it, you can then say ok, what made this tactic possible? When you ask yourself that question you will see that the answer is that your bishop is making contact with his knight, your rook is X raying his knight and thus it is also pinning the opponent's c pawn. Your light square bishop is attacking the d5 pawn which is defended by the pinned c pawn. Noticing things like this can help you spot more tactics in the future, but it is completely fine that you missed this one, as even I missed it when I was scrolling through the moves and I am 900 points higher rated than you. Still, I see what components made this tactic and that can be a good lesson for the future. Another lesson is that you can't immediately take on d5 here, because he would take back with the knight, you have to switch the order of first 2 moves which is something that GMs say you should often do when calculating a tactic. The tactic also has the attraction motif and removing the defender motif, as you first play Bxc7 to attract the queen on the rook's X ray and you simultaniously remove a guard of d5. As you see, this tactic was comprised of many tactical motifs (contact between pieces, X ray, pin, switching the order of first moves, attraction, removing the defender).
On move 20 your opponent blundered a skewer. You could have played Bd6. You spot moves like this by looking at all checks, captures and attacks and if you miss it by looking at all the attacks, you should look for when your or your opponents pieces are on a forkable/skewable squares by the bishop, knight or pawn. Either of those 2 things would make you play the correct move and win material.
I don't know why you blundered your queen on move 29, probably a mouseslip and I see no point in analysing any further as you are down a full queen. I don't know about you but I saw plenty of very valuable lessons in that game.
I'd really love for someone to explain to me how game analysis has helped you(not in the opening). I analyze probably around 50% of my games, and if it was a useful resource, I'd be getting better but I'm not. To take it a step further...when I analyze, I take the opportunities to try to find best/better moves than the ones I made...sometimes succeed...sometimes not. And even when the engine suggests the best move is something that looks like it makes no sense...I'll go deeper and take it to the analysis board and play it out till it makes sense and explore other outcomes. Pattern recognition is helpful, but this is best obtained by doing puzzles and is seen far more rarely in actual games. Memorization is super useful in openings, but is impossible elsewhere in the game. If there actually is a way to study analysis to help correct mistakes, it is beyond me. If you don't approach it with a memorization mindset then what else is there? If your knee jerk response is to say something like "ohhh board vision and positional play" just....🤦🏻♂️...just save it ya know. Analysis doesn't do anything but show you similar mistakes made but with different pieces in different positions that will never again be repeated. Don't believe the hype. My username has never been more true than it is right now. I freaking despise these 64 squares. Have a good day all!! 😂
You pay attention to what kind of mistake you made, why you made it, what you can do so that you don't make similar mistakes in the future. The engine analysis can also tell you what idea is bad in a certain situation and what is good. You can test whether some moves that you have played in your games were good or not. Analysing games helps for pattern recognition, possibly even more than puzzles, as you are analysing positions which have arised from the openings that you actually play.
