By my count, there are exactly 22,075 legal chess moves that fully
describe the change to the chess board state including captures,
promotions and castle availability. I would like to encode these moves in
a 15 bit field for an opening book. Is there already a compact move
encoding that specifies the complete move without reference to the current
board?
