White reacts classically by advancing in the centre but this  isn’t the best. The simple developing move 8.

Re1 Qxf6 11. f4   {  [#] White is trying to complicate matters and leave the pawn on g2 as  protection to his king. The simplest move for Black is now 11…Rg8 followed  by 12…Bd7 and castling Q-Side.

Bd4. However he finds a tactical way to cope with this threat and plays the  best move: Now if 15. Bd4? then 15…Qxf4 16. Bxh8 Bd6 17. Qh5 Rxh8 gives  Black a winning attack. However White is having none of that and continues  with his own attack. Qa4}} Qh4 {$2 {Black misses his last chance which was  15…dxe4, when with careful play he can hold the balance.} (11...
