Echekinator is a UCI-compatible chess engine written in OCaml.

The engine currently relies on:

• Principal Variation Search (PVS)
• Quiescence Search
• Iterative Deepening
• Null Move Pruning
• Reverse Futility Pruning
• Late Move Reduction
• PeSTO's evaluation function
• Killer moves
• History heuristic
• Transposition Table
• Lazy SMP
• UCI Protocol

git clone https://github.com/Tym972/Echekinator
cd Echekinator
opam install . --deps-only
dune build

The compiled engine binary will be located in:

Echekinator/_build/default/bin/echekinator.exe

To run the engine (raw UCI):

dune exec bin/echekinator.exe

Echekinator will be tested on the CCRL lists.

• CCRL 40/15 rating: TBD
• CCRL Blitz rating: TBD

No official rating available yet.

This project would not have been possible without the help of the Stockfish Discord server. Special thanks to:

• Fastchess for engine tournaments
• Chess Programming Wiki
• PeSTO for the evaluation
• Arthurus on YouTube for the inspiration
