lila VS api

Once you’re finished, we’re going to set up a lichess bot account. Head over to https://lichess.org/ and create a new account.

Lichess - Online Chess Server. Scala, TypeScript

> 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.

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.

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.

if you actually like chess, try lichess.org, the free and open-source, no ads ever, premium alternative

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

API's are used to talk with web servers like Lichess: 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.

Here is documentation on the Lichess Bot API: https://lichess.org/api

Considering you have some "data science" experience with Python, you might be interested in doing some analysis based on data you can get from the Lichess API or databases.

The Lichess API is documented at https://lichess.org/api

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 :))
