I don't think kirbies would be useless at all. What I'm suggesting is that kirbies be allowed to capture only _other kirbies_. Kirbies can't capture other pieces, and other pieces can't capture kirbies, which still makes kirbies very useful to block other pieces.
At first allowing kirbies to be captured by the enemy king sounded pretty appealing to me, but then I thought about it and it has a fatal flaw. If the white king is hiding behind a wall of kirbies, the black king won't be able to take any of them because that would require moving into check. |
