15...♕c6 16.h5 ♘b6 17.♗d2 Diagram # The idea is Be3-d2-a5-b4-d6 17...♗d7 ( Maybe : 17...c3 is to be preferred) 18.♗a5 ♕c7 19.♗b4 ♘a4 20.c3 a5 21.♗d6 ♕b7 22.♘g5 ♖h6 23.♗h3 ♘f5 24.♗xf5 exf5 25.♕c2 b4 (25...♖xd6?26.exd6 ♗e6 27.♘xf5+⁠−) 26.axb4 axb4
Not 26...♗xd6 27.exd6 axb4 28.♘xf5 bxc3 29.♕e2 ♗e6 30.♘xh6 cxb2 31.♖b1 ♕b4 32.♔f2+⁠−
26...♖xd6?? is most certainly to be avoided 27.exd6 axb4 28.O-O bxc3 29.♖fe1 ♔d8 30.♘xf7 ♔c8 31.bxc3+⁠−
27.O-O ♗xd6 (27...b3 28.♕e2 ♗e6 29.♖a3⩲) 28.exd6 ♖xd6
A much better option was : 28...♔f8 29.♘xf5 ♗xf5 30.♕xf5 ♖xd6 31.h6 ♖xh6 32.♖fe1± but can Black hold ?
29.h6±29...♖xh6 (29...gxh6 30.♕e2 ♔f8±) 30.♖fe1 ♔f8 31.♘xf5 ♗xf5 32.♕xf5
