no computer, so OTB here, but if Bc5 Qf5 Qxa2 then e6 wins, I think eg pxe6 pxe6 RxRd1 and mates via Qf7 and Qxf8

Qxf8 won't do as the knight is covered by the c5 bishop.
e6 is no threat because of ...Qxb2 and there's no mate on g7, just a single check on f7.

No computer, just a quick look. I wonder if 1... Bc5 2. Bd5 is playable.

Bxd5 Qxd5 Qxa2 Bf5 black is a pawn up, but white with dominating centre, black nite not going anywhere sensible and nasty break with e6 waiting in the wings. what can black do? push the a-pawn? White should win. Probably everything wins here

Any serious problems after 2. Bd5 Bxd5 3. Rxd5. Does White need to be in a hurry to force things?

After 32...Bc5, Qe2 is best:

+3.05 33. Qe2 Re8 34. a3 Bd6 35. e6 Re7 36. Rf1 f6 37. Be4 a6 38. a4 Qb4 39. Rb1 Qxa4 40. Ra1 Qe8 41. Rxa6 Qb8 42. Qg4 Kh8 43. Bd4 Re8 44. h4 Qd8 45. Be3 Qb8 46. Kh3 Qd8 47. Ra7 Qb8 48. Ra2 Qd8 49. Kg2 Qb8 50. Bd4 Qd8 51. Ra6 Qb8 52. Ra1 Qd8 53. Be3 Bc5 54. Bxc5 bxc5 55. Ra7 Qb8 56. Ra6 (depth 41, 0:05:21)
