Avoid blundering: 80% of a winning strategy
> the player who committed more blunders lost 86% of the time
In some sense this is almost tautological. While finding an exact definition for a chess blunder isn't straightforward, here is one example from the Lichess UI:
https://github.com/lichess-org/lila/blob/b527746b179cdde6438...
Basically, if you make a move which decreases your winning probability more than 14% over the best move, that's a blunder. But winning probability is a nonlinear function of stockfish centipawns. A drop in 100 centipawns when you're up 15 points isn't a blunder. When the game was equal, it is.
Point is, by the time you know it's a blunder you already know something about the outcome of that move, that it swung the winning probability by more than 14%. So the analysis is kind of just measuring some function of winning probability and saying that it is highly correlated with winning probability.

So bad at chess that it’s genuinely upsetting at this point, I need some hope
If you want to improve make it your goal to play the best chess you can, not increase an arbitrary number. Watch YouTube series like John Bartholomew's "Climb the Rating Ladder" for some general insight into what you might be doing wrong. Read Irving Chernev's "Logical Chess: Move By Move" to see the thinking process of high level players. Do lots of puzzles (I like lichess.org for puzzles). And always analyze your games. When you analyze make it your goal to find at least two things you could have improved.

Humans vs. Stockfish’s eval function
The easiest way to play against Stockfish is perhaps on https://lichess.org/, but it's not the only chess engine that evaluates positions with a neural network.

I got a Chessnut Evo to review, here are my thoughts
The Chessnut Evo works almost flawlessly (I did not experience this issue but people have reported having ChessnutVision stop working on occasion which requires turning on/off to fix) with popular chess sites (officially supported are chess.com, lichess.org, Chess Kid and Chessable). I experienced no major lag when playing games on Lichess through the board There is the unavoidable delay of physically moving pieces, so it may not be ideal for blitz But for rapid or longer time controls. the ability to have your OTB games instantly logged and the ability to effortlessly analyze games after is game-changing for me. The one occasional hiccup I encountered was when quickly sliding pieces, it would register an incorrect move. But that’s an easy fix of adjusting the Limbo move delay (I don't like this option as it makes the board feel less responsive I prefer to just be aware and lift pieces instead of sliding).

How many positions can the top GMs analyze per second? In engine terms what is the highest nps for humans?
Stockfish doesn't have a classical evaluation anymore. And before this, most of the time (around 90%), NNUE was used to evaluate.
