UCI bitboard chess engine written in C++20

Description

The goal of the project is experimentation. I want to see how far I can push the engine to play better while learning various techniques of optimization.

To see the games played or play a game on your own checkout the profile on lichess, bullet, blitz and rapid challenges, ranked or casual, are accepted.

Getting Started

Dependencies

• CMake 3.25.2 or latter
• Compiler with C++20 support

Installing

• Clone the repo
• Make a build folder and cd into it
• Run cmake -DCMAKE_BUILD_TYPE=Release <path to cloned repo>

Executing program

• Run the engine by running: ./bin/engine

• The engine accepts commands on the standard input and produces results to the standard output

• To communicate with the engine use UCI command. Reference for UCI protocol can be found here

Help

• To see the options for additional tools run one of the following commands form the build directory:

  ./bin/perft -h
  

• Changes to the move generation can be tested with ctest on a predefined set of positions
