You can repair a color weakness by putting pawns on that color’s squares.

1 e4 c5 2 ♘f3 ♘c6 3 ♗b5 ♕b6 4 ♗xc6 ♕xc6 5 0-0
White’s bid for rapid mobilization should be tested by 5...♕xe4! 6 ♘c3 ♕c6.
5...g6 6 ♘c3 ♗g7 7 d4 d6 8 dxc5 dxc5 9 ♗f4!? ♗xc3! 10 bxc3 ♕xe4 11 ♕c1
11...♗f5?
White’s comp lies in potential pressure on dark square and the e-file. With 11...f6! Black repairs dark squares and prepares ...e5!.
12 ♖e1! ♕a4
After 12...♕xc2 13 ♕e3 White threatens ♕xc5 but also 14 ♗e5 f6 15 ♗xf6!.
13 ♕e3 ♕c6?
Last chance for 13...f6 (14 ♗d6 ♔f7 15 ♗xc5 b6).
14 ♘e5! ♕c8 15 ♘c4!
Question 226: Why not 15 ♘xf7 ♔xf7 16 ♕e5 ?
15...♗e6
Question 227: And if 15...♕e6 16 ♕xc5 ♕c6 ?
16 ♕e5 ♘f6 17 ♘d6+! exd6 18 ♕xf6
Black fittingly dies on dark squares (18...0-0 19 ♗h6 and mates).
18...♖g8 19 ♗xd6 ♕d7 20 ♖ad1 resigns.
In view of 20...♖c8 21 ♗xc5 ♕c7 22 ♖xe6+! and mates.
