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).

Yes you should play until you lose and stop for the day. Plot gives the expected rating gain (with bounds) for my last 2k games. There is a clear increase in expectation after waiting a 12 hours from a loss. There is a small (non stat. sig.) decrease waiting after draw or win.
If you want a specific subset of games, you can use the API (there's also a button on individual profiles to download all of their games): https://lichess.org/api

Other than that, the code is probably ready for GitHub. If you felt like extending it, you can use the lichess API to automate finding puzzles rather than having them in a file that you just read from.

I made a website for guessing the Elo of Lichess games!
I coded this in a very simple way, just an HTML page with an inline script tag with some JS for updating the UI and such. But I think using Vue.js or another framework would be great for a Lichess-based project. These three pages are pretty useful: https://lichess.org/developers (for embedding a board like I did) https://lichess.org/api (API for getting data) https://database.lichess.org/ (database, for when nothing else works :))
