History
The Spingold Master Knockout Teams, first known as the Challenge Knockout Teams, was contested for the Asbury Park Trophy in the early days. The runner-up team in the regularly scheduled portion of the event had the right to challenge the winners to a playoff. This right was never utilized. In 1934, 1936 and 1937, the Masters Teams-of-Four and the Asbury Park Trophy were separate events, providing two sets of winners. In 1938 the event became the Spingold Master Knockout Teams and a part of the Summer NABC. At one time, the Spingold was a double elimination event, usually lasting nine or 10 sessions. It was scored by International Match Points and was restricted to players with 100 or more masterpoints. In 1965, the double elimination method was replaced by three qualifying sessions (subsequently reduced to two), followed by single elimination knockout matches. The preliminary qualifying sessions were dropped in 1970. The Spingold Trophy, donated by Nathan B. Spingold in 1934, is one of ACBL's most highly prized team trophies. The event, which attracts virtually all of the world's best bridge players, is widely considered one of the toughest events in the world. Many bridge aficionados consider the modern day Spingold tougher to win than a World Championship.Winners
