1) ... Rxe8+ 2) Bxe8 Nxc6 if 3)Bf7 Nxb2 4) Bxb2 Bxb2 and later Bxa1. If 3) c3 or Nc3, then N(c4)e5 traps B. If Bl has a force mate, I don't see it.

If 3. Bf7 Nxb2 better than 4. Bxb2? and winning for white would be 4. Nc3!.

And if 3. c3 or 3. Nc3 then either 3...N4e5 or 3...N6e5 don't trap white's bishop on e8 due to 4. d4, and after the knight on e5 moves to safety the e8 bishop can escape via f7 (3...N6e5 4. d4 Nd6 5. dxe5 Nxe8 of course is an even piece exchange). Better would be 3...Nd6 which does indeed trap the e8 bishop.
