However, Collins became better known as an author and teacher. He was a regular Chess Life columnist in the 1950s. He is known for his book "My Seven Chess Prodigies: Bobby Fischer, Robert E. Byrne, William J. Lombardy, Donald Byrne, Raymond A. Weinstein, Salvatore J. Matera, Lewis H. Cohen", all of whom he taught.
He was co-editor of the ninth edition of "Modern Chess Openings" and also wrote "Maxims of Chess".
Later, he became better known for his Collins Kids globetrotting events. He had hundreds of students, most of whom he taught in his home.
Collins was not entirely without controversy. He was close to Bobby Fischer but Fischer did not like it when Collins claimed that he had been Bobby's teacher. Fischer said that Collins never taught him anything. Fischer was already near to master strength when he first met Collins in June 1956. When Collins came to Iceland during the 1972 Fischer - Spassky world championship match, Fischer refused to see him except for one extremely brief appearance. Later, Collins stopped claiming to have been Bobby's teacher.
I played Collins in the 1964 Manhattan Chess Club Championship preliminaries. He beat me without much difficulty. I would like to get the game score, because I have lost mine and he kept everything.
I last saw Collins in February 2001 at the US Amateur Team Championship East in Parsippany, New Jersey, when I played for one of the Collins Kids Teams. I reminded Collins that he had defeated me in the 1964 Manhattan Chess Club Championship Preliminaries. "That wasn't me. I am not that old", he quipped.
