See Chess StackExchange for a similar question.

I know some chess, but I can't clearly see why you need 8 bytes to represent the positions of white or black pieces, and what additional information there is for white pawn, rook, knight, bishop, king, and queen to fit into 6 bytes. Can you give more details?

Also, there might be a way to serialise the board that is very efficient but not really usable (with each piece positioned, you have one less possible position, which might lead to some bit savings in the early stages of the game, for example).

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
