>[report of an illegal move by gnuchess]

That's because the new move generator in gnuchess 1.53 is buggy.
It's faster than the old one, but it doesn't understand that
a blocked pawn can't move two squares. It also doesn't know about
en passant captures. I'm told the author has been notified.

I suggest sticking to the previous release for now, gnuchess 1.52.
