Which was the game where Marshall, I think that with Black, made a spectacular Queen sac in g3 (White pawns on f2, g2, and h2, King in g1). The Black Queen could be taken with the f and h pawns and also with a third piece, and all variants led to different checkmate themes.
I believe that the audience started throwing gold coins after Qg3 was made.
UPDATE: I changed Murphy's mentions in the original question to mention Marshall instead, as Marshall was the player who actually did the Queen sac.
