Sicilian Defense, Hyperaccelerated Dragon

In the Hyperaccelerated Dragon, Black plays 2...g6 before developing the b8-knight or moving the d-pawn. The plan is to place the bishop on g7, where it will point toward the central squares and the queen's side. This development is called a fianchetto: the g-pawn moves so the bishop can use the long diagonal.

The early move order preserves the option of playing ...d5 in one move when the position allows it. In the traditional Dragon, Black's pawn is usually already on d6 and would need two moves to reach d5. That difference can create more central activity, but it does not make ...d5 automatically safe.

The cost of flexibility

By delaying ...Nc6, Black permits responses that do not arise in quite the same way in the normal Accelerated Dragon. After d4 and an exchange on d4, White can recapture with the queen in some lines. White may also choose c3, c4, or positions in which the central pawns are not exchanged early, forcing Black to show the intended plan.

The name mainly describes a move order. If Black later plays ...d6, ...Nf6, and ...Bg7, the position may resemble a standard Dragon, but the earlier options still matter. The Yugoslav Attack belongs to the traditional Dragon and does not arise automatically against this move order.
