White wins

1. Bg7+ White cannot capture the a1 bishop immediately because the f8 bishop is also hanging: 1. Kxa1? Rxf8 = 1... Kd5 2. Bxa1! 2. Kxa1? fails because the bishop from g7 would become again a good target for the rook. 2... f2 3. Ng3! Rf5! 4. Be2 Rg5 5. Nf1 Rxg7 = 2... f2 3. Ng3! 3. Nxf2? Rxf2 = 3... f1=Q+ 4. Nxf1 Rxf1+

5. Kb2!! A surprising move which closes the bishop on the corner. Thematic try: 5. Ka2? Rxa1+! with check 6. Kxa1 Kc4 = 5... Rxa1 without check! 5... Kc4 6. Be2+ +-; 5... Re1 6. Bf7+ Kc6 7. Bc4 +-; 5... Rf5 6. Bd1 Kc4 7. Ka3 Rf1 8. Be2+ +- 6. Bf7+! 6. Kxa1? Kc4 = 6... Kc6 7. Be8+! 7. Kxa1? Kb5 = 7... Kd5 8. Kxa1 Kc4 9. b5! +-
