For the problemsolver:
The checkpieceFacts method must be changed so that it can check for protection by any piece

After move: Bf5 the Knight at d5 is replaced by the white pawn !!
The Knight moved from b1 to d5 !!!

PROTECTEDBY(x,d5)
Is found to be true, but x is not instansiated to WhiteBishop2 !!!

NO MOVE !!! Checking piecefacts for
PROTECTEDBY piece WhiteBishop2 and action ChessAction: Preferred Position Unknown Piece Piece position f1 X, Y (5, 0) wB f1 BISHOP
