Ah, I didn't realise the problem was not realising pieces could move back from board B to board A. Now I look at it, I see the article wasn't clear about this. I'll try to edit it further so there can be no mistake. As for the rest: I think there's a general need for more diagrams. The game is, indeed, quite tricky, so it's hardly possible to provide too many for the newcomer. I'll make some more now. See what you think.
