A "Ten seconds per move" knockout.

Many people think that Chess games last hours and are boring; to a degree this is true. Oscar Tenner as Black executed the following "ten seconds per move" master piece against Otis Field in New York in 1923. White resigned before making his 18th move, he can capture any of the three black pieces but he cannot stop mate next move. Chess do not have to be a long and boring game. I hope you all enjoy.
