Spotting my own weakness with chess tools


I think it would be great a tool that load your bad games and represents them randomly, to fortify your weakest points.

The best thing to do is look at your games right after playing them. You will know at what point you felt you were in trouble, or found it tricky, or thought "I'm sure I have a mate here" but couldn't find it. Go back to those points, and if you're in a tricky position, try and work out how you got there - what did you miss? What move did you make that caused issues (or what move did you overlook that could have prevented the whole situation)? If you think you had a mate but couldn't find it, go back and calculate again without the time pressure and see if you can find it.
After you do that, then load up the engine and see what it has to say. If you don't spend your own time on the position, trying to understand it yourself, looking at the engine won't help much because you won't remember what it told you. You need to try and solve the puzzle first, and even if you can't, it's trying to do it that makes the answer memorable. And if you do that, you will notice the pattern in your mistakes, which in turn will let you know what you have to work on.
You should be able to analyze your games on your own. Go through your games and identify the major mistakes. Then try to classify them (e.g., time pressure blunder, calculation error, lack of opening understanding, etc). If you look at 20 or 30 games, you should be able to identify patterns and find things to work on.
At your level, you should not need a sophisticated program to evaluate your losses. The errors will be fairly basic and easily identified.

Yes, my mistakes are usually blunders I didn't see. Distractions, in a daily game, not time pressure.
I always review a game, to see my mistakes. Sometimes the machine tells me a 10 moves consequence of a mistake, and I try to understand them but I don't think I will be able to replicate some way soon.
It would be nice to load games I played casually to see if I remember and avoid my mistakes. it's not easy, because If I download the position two or three moves behind, I will know there will be a mistake soon and I will double think. But it will train me to read those warning, I think
Hi there... Can somebody tell me how can I use chess tools to spot my own weakness analysing the games I lost in the last, let's say, 3 months. Something like a tools (or a set of tools combined) that allows me to see the the patterns of my blunders. I guess the best indicator is based on the score the engine gives me for each move... bla bla.
Let me know please
