Hyperaccelerated Dragon Sicilian defence B27 2...g6 · Hyperaccelerated Dragon Black prepares to fianchetto their king's bishop, ...Bg7. This is the start of the Hyperaccelerated Dragon. In the Accelerated Dragon, Black usually plays 2...Nc6 before preparing to fianchetto their bishop. This allows White the option of 3. Bb5, the Rossolimo attack. With the move order 2...g6, Black hopes to sidestep that line. The main continuation is the usual Open Sicilian plan: 3. d4 cxd4 4. Nxd4, and 4...Nc6 transposes to the Accelerated Dragon, Rossolimo successfully avoided. White can continue with 5. Nc3, the conventional Open Sicilian move, or 5. c4, the tricky Maróczy bind, which clamps down on the d5 square with both e- and c-pawns. However, the 2...g6 move order gives White some other options that steer the game away from transposing into an Accelerated dragon, which Black must be prepared for: 3. d4 cxd4 4. Qxd4!?, attacking Black's rook. The main continuation is 4...Nf6only 5. e5 Nc6 6. Qa4 Nd5 7. Qe4. 3. c3, a sort of deferred Alapin, is also strong. 3. c4 transposes to the Maróczy bind line after 3...Nc6 4. d4 cxd4 5. Nxd4 Bg7. Theory table 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 Bg7 6. Be3 Nf6 7.
