Because as I said if you think black playing Nxf2 would win no matter what moves white makes later on, then I disagree totally. Why not let two strong chess programs fight this out, I would say the top five chess programs today would be stronger than the two players who played that game. And see if black will still win. Somehow I do not think they will. I played CM6000 as white and CM5500 as black, on equal machines and white won. I did save the game, but when I went to look at it yesterday there was an error in the file, but I am sure you should be able to play two top programs against themselves and you might see white can win. I will over the weekend try and play this game from the Nxf2 and see what happens this time.
