That’s rough. I would have conceded the match in the old boy’s place. It’s an absolutely absurd situation.
How about changing the rule regarding stalemate situations to prohibit occupying a space on the battlefield that is inaccessible for attack?
Retreating when you can’t catch up is still somewhat fair, but when you can’t even attack, it’s just plain idiocy.
That’s exactly what I suggested.
If the rule is revised to prevent such situations from recurring in the future, I agree not to insist on its application in this match.
