To Each His Own

The following game was originally made public by Massimiliano Enzo Maria Orsi on his own website Italian Castling, which features a constantly updated archive of Italian chess history. The game is all the more interesting because it confirms, once again, that Roberto Cosulich was a bête noire to the American Stuart Wagman.
