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).

Chess-GPT's Internal World Model
> The problem is that a stockfish based bot knows some very strong moves, but deliberately plays bad moves so it’s about the right skill level.
What are you basing this on? To me it seems like difficulty is set by limiting search depth/time: https://github.com/lichess-org/fishnet/blob/master/src/api.r...

Initial eval graph doesnt change after subsequently increasing depth
The eval graph comes from an analysis done by fishnet. The analysis that you see changing is done locally in the browser on your device. That is why there is a difference.

Is Lichess getting slower for people?
YOU can help by running this: https://github.com/lichess-org/fishnet
- January was a month of records for Lichess 🎉 - 147,000 concurrent players - 161 million games played - More than 4 million active users - Almost as many new accounts created as November and December combined - 4 billion games in the Lichess DB - Such an amazing start to 2023!
-
Why is Lichess analysis limited to 15 CPUs for me?
Game analyses are made in a distributed way, but only accepted from users they trust. You can check the tool they use for that here and they instructions to use it.
-
chess.com analysis of the same move in back-to-back games
It's not on the user's device and not on their servers. The game analysis is done by fishnet using donated CPU time.
-
If Chess.com made all of their premium features free, would you prefer it over Lichess or would Lichess still be better?
You can run a program on your computer, so that Lichess can run Stockfish analysis using your CPU https://github.com/lichess-org/fishnet
