As I understand it, Fergus has decided to program a variant based on yours, and given it a different name to signal that it's not the same game. As a game in itself yours remains intact (and probably eventually publishable too if and when the Editorship approves), just more difficult to program given the primitives that Game Courier provides.

This game differs from yours only in that both a4 and 4, or both 5 and h5, can be occupied/passed through simultaneously. As such those spaces connect to the rest of the board in the same way they do already, they just stop being a ‘switch’ in the railway sense (aka a ‘set of points’ in my native British English, or German ‘Weiche’ as used in your original German page) and become just an unusual topological/geometrical feature of the board.

I'll admit I find it a little odd that such conditionally untraversible squares should be so difficult to implement (couldn't it be done with uncapturable dummy pieces that appear and disappear as the other square is occupied and vacated?), but I'm not a programmer and I've never had a go at writing GAME Code, so…
