The goal with this project is to create a fully working chess game played against an algorithm.

run with 'python chess.py'

TODO:

1. Pawn movement and taking (special)

   • one direction
   • two steps possible first move
   • taking only diagonal, movement only straight
   • en passant

2. All other pieces but king and knight general movement and taking

   • Rook straight
   • Bishop diagonal
   • Queen is rook + bishop
   • Knight is special case, can jump over pieces

3. Make piece movement that exposes the king illegal

   • Detect if king is exposed

4. Only move that covers the king is legal if in check

   • Restrict movement, detect if a piece is allowed to move

5. Use 3. logic when moving the king

   • Restrict king movement

6. Castling

   • Check if piece is blocking
   • Move both rook and king
   • Check that neither rook nor king have been moved during the game
   • Check if piece is attacking in between squares
   • Check if king is in check before castling
   • Check if king would be in check after castling

7. Can't take king

   • Block enemies from taking the king

8. Check mate

   • Detect when it's check mate

9. Implement turns

   • Make Player modules that can be played be a human or by the computer

10. Implement queening

    • When pawn reaches enemy back rank, make choice to have new piece

11. Implement draw detection

    • When no move can be made but it's not check mate
    • When only the same move can be made over and over

FIXME:

1. Castling doesn't work when playing
2. You shouldn't have to reselect piece when you tried to make an invalid move
3. Redraw board after invalid move attempt
