In parser rules, you _can_ use "literal tokens", but it's best to refrain
from doing this: create separate lexer rules for them. And the `..` (range
operator) is only valid inside lexer rules. So the rules `enPassant` and
`pieces` are not doing what you think they are.
Change those things and try your grammar again.
Regards,
Bart.
