ChessAI

My implementation of a console chess game with opponent AI.

Current goals

• Implement chess board and pieces
• Implement pieces moves
• Create opponent that moves pieces randomly
• Implement checks, checkmates and draws
• Implement game history output to file
• Implement opponent AI using minimax criteria (freecodecamp article, arXiv:1404.1515, arXiv:1208.1940)

Requirements

Tested on Ubuntu 20.04.5 LTS.

• Haskell stack.

How to run

To run the game you can simply run the shell-script run.sh.

How to play

First you should choose the color of your pieces.
Select color ('B'/'W' or 'q' to quit):
You can type any string starting with b or B to play for Black pieces or string starting with w or W to play for White pieces. You can quit the game by typing any string starting with q or Q. When the color is selected the game board will appear.

Move for White.

If you decided to play for White you can choose the way you are going to move your pieces. For example you can type: e2e4. This will affect on the game board in the following way.
