1...Qxb2!? 2.Qf6!?

   [2.Kg2! f5! 3.Bf4
      (3.c4 Ra5 4.Rd1 Bf6 5.Qd3 Qe5 6.Qd7 Qe4+ 7.Kg1
         (7.Kh3 Qg4+ 8.Kg2 Qe4+ =)
       7...Re5=)
    3...Bxf4 4.Qxf4 Qd2 5.Qb8+ Rd8 6.Re8+ Rxe8 7.Qxe8+ Kg7 8.Qe7+ Kh6
    9.Qf8+ Kh5 10.Qe7 Kh6 =]

   [2.Rxe5 Rxe5 3.Qf6 Qb1+ 4.Kg2 Qe4+ =]

2...Qc1!

   [2...Qxc3?? 3.Qg7+! Bxg7 4.Re8+ Bf8 5.Rxf8#]

   [2...Qa1? 3.Qxe5 Rxe5 4.Rxa1 +-]

3.Qxe5 Qxh6 4.Qf6 Qf8 =+
