Subject: Reset 50-move counter on all pawn-like Lance moves
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=e0691ae1d55be2a77484f99294ab28cd5f6e381a;p=xboard.git

Reset 50-move counter on all pawn-like Lance moves

Now the Lance represents a Pawn-like piece not only in variant fairy,
but anywhere outside Shogi / Superchess, its moves should also reset the
50-move counter in those cases. Especially important for Spartan Chess,
where the Lance actually participates.
