Why is a blunder a blunder?

I use the analysis engine a lot after games. One of the things I find frustrating is trying to decipher why blunders are blunders and mistakes are mistakes. I can follow the alternative suggestions and watch how the engine plays out different scenarios, but maybe a good idea would be for the analysis to play out a scenario based on my mistaken move, so I can see exactly where I went wrong.

Can anyone give any hints or tips and how to find out why my moves are labeled blunders as this would be a really great way to learn. I’m not talking about when I leave my queen hanging, the obvious one speak for themselves.

Thanks

A mistake is when I pull out a bad piece away from an uno stacko building, leaving me in zugzwang. A blunder is when everything drops because I choose a bad piece to remove.

The "Blunders", "Mistakes" and "Inaccuracy" given by the engine are labels corresponding to how bad the move is measured in centipawns. For Stockfish I think it is  defined as: Blunder~300 cp, Mistake~100 cp and Inaccuracy~50 cp. So there is not a deeper philosophic explanation behind it.

What engine tells you that black is 300 cp behind before the game starts ?

So why is a blunder a blunder? I mean ok it can be measured in cp etc, but how do I find out why?

Well, the engine doesn't tell you exactly why. It is not a teacher. So it seems as if the engine labels something a blunder if the move enables the opponent to get a fatal advantage, a mistake if it enables the opponent to get an advantage that is not as bad for you compared with the blunder, and an inaccuracy if it enables the opponent to improve his position on behalf on your position.  Something like that. But you need a teacher to teach you on what is going on.

Well that would obviously be a blunder ✌️✌️✌️

The fastest way to find out is to look at the computer recommended moves and look a few moves ahead. If the material is equal and you cannot spot any advantages then you should ignore it. If the computer recommend weird moves, then you can test out your own moves and see what the computer responds with. If you cannot see the advantages a few moves ahead then you should ignore it. Computers are a lot stronger than human players and it can requires skills to understand the computer.

A move that would enable your opponent to get a fatal advantage.

Whether the opponent actually does take advantage of your blunder is another story. You can be lucky that he doesn't see the opportunity.

The worst bunder is sitting there thinking while the clock is running.  It is not taken into account by any computer, but when I read "Saved by the Clock" I have to laugh.  I often win with only a King against a fairly large array of pieces on the clock.  And exchanging queens is not a blunder.  I love it.
