When i learned to play Chess it was the 21 move rule.
50 moves is like a life time. Even 21 is too much.
That's a "kiddy rule", like free money in Monopoly. When I was a schoolboy it was worse: 21 ply (10 1/2 moves). Even KQ v K is hard for beginners under that restriction.
It would have been bad luck for the white player in this situation (mate in 16):
The longest KQ v K mate is 10 moves, so even a good player might have trouble doing it in 11.
The 50 move rule does not apply to the example given, because the pawn moves. Also, I don't know about FIDE, but at a tournament, about 6 or 8 years ago, a guy was told he had to demonstrate a forced checkmate to get around it. That was USCF. TD Randy Hough.
Ok you used the words "forced checkmate". Now all mates are not completely force. An opponent blunder into a situation and mate is just waiting next move.
I have to assume the words are used when it is mate in like 7 moves(random number i pick) and nothing the opponent can do about. In the situation of the tournament i would assume that a chance for mate was possible. But they do not have all day and they have to speed things up with a result and post result of the tournament in a timely manner. Which i can understand agree with in that case.
Yes. The guy had to demonstrate the FORCED checkmate on the board, to the TD. (He did it, by the way, and won the game.)
