Playing Score4 (Connect Four) with my C++ Minimax engine

Programming AI using functional and imperative languages: I implemented a Score4 (Connect Four) Minimax engine, using C++, Ocaml, F# and C#. I wrote a blog post about it at: https://www.thanassis.space/score4.html , and released the code in Github: https://github.com/ttsiodras/Score4 . A Win32 binary is also available here: https://github.com/downloads/ttsiodras/Score4/Score4-win32.binary.zip
