Tested and working...Clover is No Joke Folks....Enjoy!! 
Clover
Clover is a chess engine, written in C++, inspired by my favorite plant. Since the 2020 lockdown, I got bored and decided to combine the 2 things I love the most: chess and programing, into making a program that can beat me.
Features
Clover now has a page with all the features: https://www.chessprogramming.org/Clover .
Fathom
Currently, Clover supports Endgame Tablebases, thanks to Fathom.
Usage
Clover is UCI compatible, but doesn't have a GUI, so, in order to play with it, you need a GUI like Arena, Cute chess etc.
Compiling locally
If you want to compile locally, I recommend you to use:
g++ *.cpp *.c -march=native -Wall -O3 -o output.exe -std=c++17
without -flto, because it crashes for some strange reason.
If you are compiling on Linux, you need to add -pthread to your command line.
In the future, I will add a makefile too.
Testing
These are the versions sorted by speed, the ones at the top being the fastest:
-bmi2, supported on any CPU that supports bmi2
-popcnt-avx2, supported on any CPU that supports avx2
-popcnt, supported by most non-ancient CPUs
normal version, no additional compile flags
UCI
Setting thread count, Syzygy Path and Hash size is now available.
Additional UCI commands:
Perft command (after setting position)
perft <depth>
Eval command (after setting position)
eval
Tune command
tune <nrThreads> <path for positions>
Bench command
bench <path for positions>
Contributing
If one spots a bug or finds an improvement, I'm open to any suggestion.
