I'm actually rather surprised that a 2300 just resigned in that position. After all, he is 1000 points higher rated -- make the 1300 nervous by forcing him to prove why his extra queen will force mate.
In any case, I wish those masters would do such a thing for me
This is just to show that masters may not be as good as they seem...http://www.chess.com/games/view?id=198942
