The Sicilian Defense: Hyper-Accelerated Dragon arises after 1.e4 c5 2.Nf3 g6 and falls under ECO code B27. By playing 2...g6, Black signals the intention to fianchetto the king's bishop to g7. The key difference from the standard Accelerated Dragon, where Black typically plays 2...Nc6 first, is that 2...g6 avoids giving White the chance to enter the Rossolimo Attack with 3. Bb5. After the standard Open Sicilian sequence 3. d4 cxd4 4. Nxd4, the move 4...Nc6 transposes into the Accelerated Dragon with the Rossolimo safely bypassed. From there, White can proceed with 5. Nc3, the conventional Open Sicilian approach, or opt for 5. c4, the Maroczy Bind, which restricts the d5 square by placing both the e- and c-pawns on it. That said, the 2...g6 move order does open the door for White to pursue independent lines that do not transpose into a regular Accelerated Dragon, so Black needs to be prepared for those alternatives. With 12.9 million Lichess games across all rating levels, it is one of the most popular openings.
