King can be the most vulnerable

In the game which follows, Black does not castle and moves his King to the queen side in search of safe squares. White however utilizes all his pieces into the attack and sets up a neat checkmating net.

White: Alexander Bangiev (2400) – Black: Thomas Schunk (2276)

Germany, 1999

9...Be7. If 9...c5 10.c3 Nc6 11.Nh2 Ng3 12.Bxf4 Ne4 works better for Black

Black is perhaps hasty in this pawn push. Better is 14...c5 15.Nc3. 15.Nd2

Despite a few good moves available for Black, he fails to select wisely. He should have played 20...Nxe5 20...Bxc1 21.Rxc1 Nxe5 22.Qd4 Qc7 23.Rf2 0–0 or even 20...Be7 21.Be3 Nxe5
21.Nf3. If 21.Bxg5 Qxg5 22.Nf3 Qe3+ 23.Kh1 g5 is better for Black. 21...Qxc5+ 22.Kh1 Be7. Once again Black could have given a thought to 22...Be3

Worth a look is 32...Rgb8 33.Bc1
