Works with Windows, MacOs and Linux.

gamefile is :

• A PGN file (.pgn or .txt)
• A FEN (example: python3 src/ChessAnalyzer.py "r1b1k1nr/pp3ppp/n3p3/2pp3q/3b3P/N3PNP1/P2B1P2/2RQKB1R b Kkq - 0 10")

When you give the program a PGN file, it analyzes all the moves in the game, then you can review each move and see if it was the best one, a good one or an mistake.

The program file show you the best move for this configuration

• Press r to rotate the chess board
• Press f to print the actual FEN in the terminal
• Press p to print the score of the move and the score of the best one

On this screenshot, white has played fxe4, which is a mistake because it gives mate in one move for black. The best move was Kd2 with a score of -3165.
