if they are discarded, something is wrong with them..  IE moves like "bc4"
rather than "Bc4" is in violation of the PGN standard.  Adding "EP" to en-
passant captures is also in violation of the standard.  I'm not aware of
Crafty not accepting valid PGN moves.  But Enormous certainly has a few
errors.
