Dependencies

Compatible with Python 3.x

Python Libraries

pip3 install pymongo python-chess numpy requests

Database

Configuring

Create conf/config.json

{
  "api": {
    "url": "https://lichess.org/",
    "token": "token"
  },
  "stockfish": {
    "threads": 4,
    "memory": 2048,
    "nodes": 4500000,
    "update": false
  },
  "db": {
    "host": "localhost",
    "port": 27017,
    "authenticate": false,
    "authentication": {
      "username": "username",
      "password": "password"
    }
  },
  "irwin": {
    "train": {
      "batchSize": 5000,
      "cycles": 80
    }
  }
}

conf/config.json contains config for stockfish, mongodb, tensorflow, lichess (authentication token and URL), etc...

Build a database of analysed players

If you do not already have a database of analysed players, it will be necessary to analyse a few hundred players to train the neural networks on. python3 main.py --no-assess --no-report

About

Irwin (named after Steve Irwin, the Crocodile Hunter) started as the name of the server that the original cheatnet ran on (now deprecated). This is the successor to cheatnet.

Similar to cheatnet, it works on a similar concept of analysing the available PVs of a game to determine the odds of cheating occurring.

This bot makes improvements over cheatnet by taking a dramatically more modular approach to software design. modules/core contains most of the generic datatypes, BSON serialisation handlers and database interface layers. It is also significantly faster due to a simplified approach to using stockfish analysis.

modules/irwin contains the brains of irwin, this is where the tensorflow learning and application takes place.

Irwin has been designed so that modules/irwin can be replaced with other approaches to player assessment.

Env.py contains all of the tools to interact with lichess, irwin, and the database handlers.

main.py covers accessing the lichess API (modules/Api.py) via Env to get player data; pulling records from mongodb, analysing games using stockfish, assessing those games using tensorflow and then posting the final assessments.

You can’t perform that action at this time.
