Planning strategies:
For all my actions:
Give the piece of this action a new position from the list of available and not removed positions.
(produceLegalMoves)
the use the player to calculate all removed positions
(calculatePreferredPosition).
Then find which opponent pieces I can take.
And find which of my own pieces I protect

From the temporary knowledge base:
occupies(WhiteKing,f1)
REACHABLE(WhiteKingf1,g1)
REACHABLE(WhiteKingf1,g2)
REACHABLE(WhiteKingf1,e1)
REACHABLE(WhiteKingf1,e2)

These facts tell that we can reach certain positions given that we occupy f1

[olufjen]

The prepareAction method must be reworked.

[olufjen]

Add to the result knowledge base:
which positions are occupied by opponent pieces.
Then:
Which position is occupied by the opponent king?
Which position is occupied by the opponent queen?
Which position is occupied by the opponent rooks?
Can I reach any of these positions?
Can I reach any of these positions if I move a piece to a reachable position?
