Member of the "Good Companion" and champion of it in 1917, Giorgio Guidelli published more than 400 problems in 2 moves. 70 of these problems are included in Alain C. White's Christmas Series "The Good Companion Twomover" (1922). Guidelli was one of the very best twomover composers of the time.
A few details can be read on Wikipedia (Italian).
