Dr. Erwin Nievergelt

    Erwin Nievergelt (April 29, 1929 - August 4, 2018) was a Swiss IM, mathematician and economist. Born in Zurich, he was one of Switzerland's biggest chess hopes in the 1950s, but his chess career was hindered as a result of his increasingly focusing on his professional career in the fledgling fields of Operations Research and Computer Science. 

    Nievergelt graduated from University of Zurich and in 1956 he defended his thesis Die Rangkorrelation (Rank Correlation) for a Doctor of Philosophy. He worked in the area of business informatics ( a discipline combining information technology, informatics and management concepts) where he developed a system of electronic processing of economic information. 

    From 1967 to 1971 he worked as an outside lecturer at University of Basel. From 1971 to 1994 he was a Professor for information systems and computer science at the University of St. Gallen. He was also involved in computer science and engaged in predicting the exchange rate using artificial neural network and Artificial intelligence. After his retirement, Nievergelt established second and third homes in Italy and Spain where he was a gifted concert pianist. 

    In chess his first notable success was at the 1954 Clare Benedict Tournament in Zurich, when he finished a surprising second behind Lothar Schmid and ahead of Max Euwe. He defeated Schmid and drew with Euwe. All together he played in five Clare Benedict Cups (1957, 1959, 1965-1967). 

    He was co-Champion of Switzerland in 1957. He played for the Swiss national team on two Olympiads: at Amsterdam in 1954 he scored 8-4. Then at Munich, 1958 he scored 6.5-6.5. Nievergelt took part in several strong international chess tournaments. He won the Swiss team championship five times. He founded the Aron Nimzowitsch chess club in Zurich. 

    In 1964, Nievergelt married Marlies Ehrensperger. They had four daughters who were very successful in their own careers: Caroline (biologist), Christine (teacher), Sabine (teacher) and Susanne (business consultant). 

    At the age of 89, Erwin Nievergelt passed away in his adopted country of Spain. The following game was played in Spain in the Benidorm Open in 2002. The event drew almost 300 participants and finished with a "Stars Tournament" that saw 12 players in a round robin with a time limit of 15 minutes plus 10 seconds per move. Judith Polgar and Ruslan Ponomariov tied for first with Polgare winning the playoff.

The idea behind this nifty little move is that it prevents the B from coming to b4 which means white's N can go to c3 with impunity. In this game white ignores that and allows black to achieve easy equality.} Be7 6. e3 {Try not to go asleep during the next 20 moves as both sides engage in dull maneuvering.} O-O 7. Bd3 Ne4 8.

White needed to play 28.Rcc1 so that if the c-file gets opened he can challenge black on the file. But not 28.Rhc1 because white is in trouble on the K-side.} 28. Qc1 (28. Rhc1 Rf8 29.
