The following game contains one of Rossolimo’s Q-sacs that was played in a game listed as being played in New York, but no further information about the tournament or his opponent is known. According to chess historian Edward Winter, B.H. Wood first published it in his Illustrated London News column in 1961. Winter adds that Chess Life did not list any New York tournaments in which Rossolimo played in 1961. Of course, Chess Life went through some pretty rough times where it was nothing more than a useless rag, so that means nothing and they did not publish news on every event that was played. Winter also points out that it is possible the game the game was not played in a serious event. Nobody knows. It could have been a local tournament or, possibly, even from a simultaneous held at Rossolimo’s Chess Studio at the corner of Sullivan and Bleeker Streets in Greenwich Village. Here are a couple of views of the location of his chess club, but since it’s has been 50 years I can’t be sure of the exact location of the Studio. I think it was in the store front on the right in the looking north view.
I am sure that if one had the time to devote to a thorough analysis with several engines and a strong enough computer a clear opinion might be reached, but a casual analysis such as I did does not do the position justice.
That said, even if Rossolimo’s Q-sac is flawed and the subsequent play is not perfect, it does not take anything away from the enjoyment of playing over the game.
