Issue with lions and chinese pieces if hurdle is capturee

Logged In: NO

I'm sorry, but I think Popeye is right !
A RoseLion (RNd2) does not guard a5 if BishopLion (LIg5) moves away ...
A Lion-type piece jumps on it's line over a hurdle and moves to one of the next squares on the line behind the hurdle if this square is empty or occupied by a piece of opposite colour. In the latter case, the piece is captured. A Lion does not jump over two hurdles.
So if we have only Ka5 and RNd2 then the RNd2 can move to b3 or b6 nowhere else.
As the Ka5 is not in check, moving the king to a5 is a valid defense.

Sorry for a slight mistake in my last comment.
Nevertheless Popeye is right !
The possible moves with wRNd2 and bKa4 (or bKa5 !) are:

You write: "A Lion-type piece jumps on it's line over a hurdle and moves to one of the
next squares on the line behind the hurdle if this square is empty or
occupied by a piece of opposite colour. In the latter case, the piece is
captured."

In our discussion, the line is the circle d2-b3-a5-b7-d8-f7-g5-f3-d2. The squares behind the hurdle a5 are thus b7, d8, f7, g5, f3, d2, b3, and a5. a5 is occupied by a piece that doesn't block the rose lion, so the rose lion should be able to capture it.

Popeye also misses the null-move for a rose. In Norbert's example, RNd2-d2 is a legal move in b).
