If black play 2...Ne7 then 3.Kxe7 hxg6 4.h7 b3 5.h8Q and game is over. or if: 3...b3 4.gxh7 b2 5.h8Q b1Q 6.Qe5+ and mate in 31. So with 1.Rxg8 white wins. >Strongest is: >1.g6 Nxg6 2.Rc8+ Kd4 3.Rxg8 Ne5 4.Rg7 Ke4 5.Rb7 Nd3 This wins also so it's not strongest but equal. Although black has a "better" move from 3...Ne5 which is 3...Nf4+ but white wins anyway.
