[#] White got confused a little bit after having encountered an unknown variation... 12...b4! 13.f4 d3 14.f1 c8 15.g1 c5 16.e3 O-O 17.xc5 xc5 18.d4 e5 19.xa8

[19.d2 may be followed by: 19...xf2! 20.xa8 e3! 21.2f3 d1 22.g2 f2 23.h3 f1 24.h4 h6 , winning.]

19...e1 20.g2 xf2 21.h3 c5 White resigned. [...]

[Indeed, after: 22.a3 xa8 , White has no useful moves and his king will not last long.]
