The Dunst Opening is a chess opening where White opens with the move: 1. Nc3
This fairly uncommon opening may have more names than any other: it is also called the Heinrichsen Opening, Baltic Opening, van Geet's Opening, Sleipnir Opening, Kotrč's Opening, Meštrović Opening, Romanian Opening, Queen's Knight Attack, Queen's Knight Opening, Millard's Opening, Knight on the Left, and (in German) der Linksspringer.
The opening often transposes into other more wellknown openings.
