This looks like a nice elegant win. By delaying the capture of the rook on c4
and preparing it with the Bishop to a2 and the pawn moves. Nice find.
I tried Qd6 instead of Qe8 but your same follow up works there also.
But now here is a position for computers to try. They should avoid Rf7 and play
as you have found, axb5.
[D]6kr/7p/p2qP1pB/1p2p3/PPr1P3/2P2R2/B5KP/8 w - - bm a4b5;
Sorry, I missed this earlier post of yours of this winning line.
End of copy and paste job
So note that 10 moves into the line, how difficult this must be for computers
when they struggle with axb5! vs Rf7?
Here again is the winning line from Paulo
1. Qxe5 fxe5 2. Rf1 Rc8 3. Bd1 b5 4. Bb3 Rc4 5. a4! a6 6. Rf3 Qe7 7.
Ba2 Qc5+ 8. Kg2 Qe7 9. b4 Qe8 10. axb5 axb5 11. Bxc4 bxc4 12. b5 Qe7
13. b6 {+-}.
