In July, 1975, I played in my second World Open (I played in the first World Open in 1973), again held at the McAlpin Hotel in New York City (once the largest hotel in New York).  William Goichberg, again was the director.  The event was again the world's largest open tournament.  There were 815 players and the winners were Pal Benko and Alan Trefler (now CEO of Pegasystems - software for banks).  Trefler was only 19 and only an expert (rated 2075).  Benko and Trefler both scored 8-1.  I won 5, and lost 4 games.  In this game, my opponent, Lee Fiacco, tried to mate me, or least get me in a perpetual check.  He overlooked my Bishop pin, checking his King and his Queen at the same time, forcing his resignation.
