Good point about the discovered check with that particular rule.
I used a little programming trick to get this to work. I'll send you the
implementation so that you can admire it. But basically, I used the
Zillions engine itself to perform most of the function.
As to the shape of the Knight leap, I opted for the simple 'L' pattern.
This means that Pawns orthogonally adjacent to the Knight's position are
captured using this rule. This would continue to allow Pawns to threaten
the Knight un-opposed. But if there is a big demand to include any
adjacent Pawn, I can implement this in a variant.
This implementation is still in need of some serious play-testing.
