The Dunst Opening arises after 1.Nc3 and falls under ECO code A00. While 1.Nc3 develops a knight to an active central square, it sees far less play than 1.Nf3 for two key reasons. First, the knight on c3 blocks the c-pawn, ruling out c4 — which can be problematic if the game transposes into a d4 system. Second, unlike 1.Nf3 (which prevents 1...e5), 1.Nc3 does nothing to stop 1...d5, since the d-pawn is already defended by Black's queen. Indeed, 1...d5 is the main response, and it carries the threat of 2...d4, which would gain space and force the knight to retreat. White can prevent this with 2.d4 (transposing into a closed game), 2.Nf3 (entering a reversed Mexican Defence), or 2.e3. The most popular approach, however, is to allow the advance with 2.e4, planning 2...d4 3.Nce2 e5 4.Ng3. The opening is highly transpositional — several Black responses allow White to reach standard king's pawn positions via 2.e4, though independent lines are also possible. With 20.9 million Lichess games across all rating levels, it is a well-established opening.
