I ran an unrated tournament yesterday. We are trying to get a new club started in an area that has not had an active club in recent years. We had a lot of variety of players, from very new players to experienced tournament players. I had never met most of them before yesterday.
As I walked the room, I heard one player say to his opponent that the opponent had 25 moves left. Hmmm… The player who made this claim was down to a lone King, while the opponent had two separated pawns and a King in an excellent position to Queen one of them unless he really messed up.
I watched for a bit, as lone-King player began counting each of his opponent’s move aloud. I intervened to quietly tell him there was no “25 move” rule, and that we could discuss the real rule once the game was over. (One could disagree with my choice to step in early instead of waiting for an actual claim. My reading of his mood was that he was getting more and more hyper and might throw a large fit if I waited longer. I didn’t know him.)
He was totally shocked, as apparently he had always played with the “rule” that a lone King must be checkmated within 25 moves or the game was a draw. I assured him that I have been running USCF tournaments for over 20 years and had never seen such a rule. I suggested it might have been a “local rule” used somewhere that he had played.(?) I explained the 50-move rule.
Has anyone ever heard this before? I have heard some pretty strange “rules”, but never this one.
