1. Kxg2 Rxd4 2. c5 Rb8 3. Rfc1 Rbxb4 4. Rxb4 Rxb4 5. c6 Kf8 6. Qd2 Rb6 7. Qa5 e5 8. Kg1 g6 9. Qxb6 +- 
 
or 6. Qd3 Kf8 7. Qa3+ Ke8 8. Qa5 h5!? 9. Kg1 Rb7 10. Qxh5 white is better.

All i could find is Rfd1 , menacing to take with Kxg2 .. 
1-Rfd1 Bxh3 2 Be5 (to allow the king to move to h2 ) Qb7 3 h3 (protecting from mate )Rxd1+ 4 Rxd1 Qe7(trying to play Qh4 to save the bishop by not alloying either Qh2 or Kh2 since it's a discovered check threat )h5 ...from now onward, it's a matter of playing on the other flank, by pushing the passed pawns, white creates many opportunity leaving black choices to either defend the bishop or slowing down the pawns.. 
that's all i could do on my own
