Gustaaf Nietvelt was the founder of the Belgian magazine "De Problemist" (1927-1931) which later merged with "Het Schaakleven".
He mostly composed twomovers. His name was given to a black defence.
"Nietvelt defence: A black unit selfpins itself because the threat must unpin it by withdrawal. The selfpinning must be used thereafter."
