I suspect this player is actually NN, who when pressed to divulge his real name, threw out 'Schrufer'

This game was played between Morphy and his chauffeur. whilst he was being driving around New Orleans looking for totty.

His name was Rufer. But people used to be dismissive of him, saying, "Rufer? Schrufer!"

This is going to be a great day!

It shows that Morphy didn't calculated everything, because there was not a way to force the victory after his combination.

I see it differently. It was a won game for Morphy. Schrufer tried to avoid the prosaic loss of material and game. However, he most likely did not see the elegant solution that would follow.
