A good sense of danger tells you to take precautions even if you don’t see specific threats.

1 d4 d5 2 c4 c6 3 ♘f3 ♘f6 4 ♘c3 e6 5 e3 ♘bd7 6 ♗d3 dxc4 7 ♗xc4 b5 8 ♗d3 ♗b7 9 0-0 b4 10 ♘e4 c5
Black’s sense of danger tells him 11 ♘xc5 ♗xc5! is OK, 12 dxc5 ♘xc5 13 ♗b5+ ♔e7!.
For example, on 14 ♘d4 ♕d5! 15 f3 ♖fd8 his king is safe and his pieces are well coordinated.
11 ♘xf6+! gxf6
But his king would be insecure after 11...♕xf6 12 ♘e5 (12...♘xe5? 13 dxe5 ♕xe5?? 14 ♗b5+). Or 11...♘xf6 12 ♗b5+ ♘d7? 13 ♘e5!.
12 ♕e2 ♕b6 13 a3 ♗d6 14 axb4! cxd4 15 exd4 ♖g8
Even if he didn’t see Black’s threat, White should neutralize the long diagonal and g-file with 16 ♗e4! and 16...♕xb4 17 g3!.
Without attacking chances, Black would have to worry about his own king. For example, 17...♔e7 18 ♗d2 ♕b3 19 ♘h4 and ♘f5+. Or 18...♕xb2? 19 ♖fb1.
16 b5? ♕xd4!
Now 17 ♘xd4?? ♖xg2+ 18 ♔h1 ♖xh2+ 19 ♔g1 ♖h1 mate.
Question 205: Why not 17 ♘e1 ?
17 h3 ♘e5! 18 ♘xd4 ♖xg2+ 19 ♔h1 ♖h2+!
White resigned since 20 ♔xh2 ♘g4+ 21 ♔g1 ♗h2 is mate.
