Ok, so this is an interesting situation. I see that you’ve already found a highly relevant forum thread:
So, if both players insist on continuing the cycle and agree to a “no result”, we can declare this game as a “no result”.
However, as noted in that thread, that’s not the only way to proceed, and possibly suboptimal. It’s a tricky situation to handle, as I’m trying to find a middle ground between being helpful and not offering too much external advice.
