1. ... Rb3 2. Bd4+ Kxd4 3. Rxb6 Rxb6 4. Kxb6 c5 5. a4 c4 ... both pawns queen in 4 more moves ... 8. a7 c8(Q) 9. a8(Q) Qc5+ forcing a queen exchange on a8. if 10. Kb7 Qd5+ or if 10. Ka6 Qa3+
after the queens are gone, with the white K on a8 and black K on d4, black picks up the g pawn, and black's g pawn will queen. the black king is too far to defend.
1. ... Rb3 looks good to me. The bishop is attacked and a second threat is Nc4+, which wins the rook. If the bishop leaves pawn a3, then it is mate by Rxa3#. So the answer seems forced: 2. Bd4+ Kxd4 3. Rxb6 Rxb6 4. Kxb6 c5 5. a4 c4 6. a5 c3 7. a6 c2 8. a7 c1=Q 9. a8=Q Qc5+! and whereever the king goes, Black can swap queens, get pawn g5 and win easily, e.g. 10. Ka6 Qa3+ 11. Kb7 Qxa8 12. Kxa8 Kf5 13. Kb7 Kf4 14. Kc6 Kxg5 15. Kd5 Kf4 and nothing stops the pawn.
A) 2. Rxb6? Rxb6 This quality gain should win easily. B) 2. Be5? Rxa3# C) 2. Bc1? Nc4+ (the point) 3. Ka6 Rxb8 is up with a full rook. D) 2. K or R move Rxb2 is up with a piece.
E) (seems critical) 2. Rg8 Rxb2 3. Rxg6 and black has still work to do, but should win.

1. ... Rb3
2. Bd4+ Kxd4
3. Rxb6 Rxb6
4. Kxb6 c5
5. a4 c4
... both pawns queen in 4 more moves
...
8. a7 c8(Q)
9. a8(Q) Qc5+
forcing a queen exchange on a8.
if 10. Kb7 Qd5+
or if 10. Ka6 Qa3+
after the queens are gone, with the white K on a8 and black K on d4, black picks up the g pawn, and black's g pawn will queen. the black king is too far to defend.
e.g.,
12, Kxa8 Ke5
13. Kb7 Kf5
14. Kc6 Kxg5
15. Kd5 Kf4
16. Kd4 g5
17. Kd3 Kf3
18. Kd2 Kf2
etc.
Rb3 Bd4
White trades pieces, then trades rooks, then trades queens and then wins a simple endgame.
Venky, I think you are afraid of posting a wrong answer. Man up and share your thoughts.

D)
2. K or R move Rxb2
