I assume your looking at GNU chess 4? The code in GNU chess 5
for move generation is fairly readable (Leastwise it was the
first bit I understood).

GNUchess 5's rare ability to make illegal moves is (in all cases
we've figured out so far) more to do with the tree handling than
the move generation.

Afraid I'm not familiar with the version 4 code base.
