Todo:

check legality of position: Max number of pieces of each type e.g. K=1, Q=9 -#pawns, N=10 -#pawns colour of bishops, double in-check, in case of ep, adjacent pawn movenumber if not initial position, location of pawns, position of king and rooks in case of castle allowed (att. 960) for each promoted piece, an opponent piece must have been taken
