>The problem is that you have 56 bits of information. 48 possible pawn >positions + 8 possible en passant target files. En passant needs at most 3 bits. On average it would need much less than even the 3 bits since after the position of pawns is specified, the en passant bits (0-3 bits) may be added conditionally as an index into the array of en passant candidates. The 48 bits specifying the pawn position thus automatically specify how many en passant bits follow.
