However it is important at all times to keep track whether the opponent’s counter attack gets in first and when to switch onto defensive mode. In the game which follows, White barges on with his attack and to a certain extent, ignores the danger and defence. Black has no difficulty in bringing home the full point.

 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.f3 Bg7 7.Be3 0–0 8.Bc4 Nc6 9.Qd2
Intention of queen side castling which is usually played in this variation
9. ..Bd7 10.Bb3 Rc8 11.0–0–0
Faithfully sticking to opening theory
11. ..Ne5 12.g4
Here White opts for a line which is not frequently played. The reason is that White loses a move here, which is not good in the opening stages or for that matter any time.
12...b5
Black also starts targeting the King. With the players having castled on opposing flanks, the race will be on to see whose attack gets in first.

17.Bb7 The bishop is practically driven from each and every square he lands on
17. ..b3 Things are getting dangerous for White as Black has come too close for comfort. He has to now think about defence first and then about continuing with his attack.

Rushing too much! He would have been better off playing19.Ba6 axb3 20.Nxb3 (20.hxg6 fxg6 21.Nxb3 Nxf3 22.Qxd6 Nxg4 23.Ba7 Qf6 24.e5 Ngxe5 25.Bxb8 Nc4! 26.Qxf8+ Kxf8 27.c3 Bb5 28.Bxb5 Qg5+) 20...Nxf3 21.Qxd6 Nxg4 22.Ba7 Qf6 23.e5 Ngxe5
