The white bishop can only be defended at some point with either Qb1 (rook traped on a1) or Nc1 (rook available squares only at a1 and b1) while black controls the a-column with the rook in a natural way. 13.- ..., Nb3 is a nice move indeed! 14.- Nxf6+ is still possible and white does not need to double pawns on d-column, although the resultant position might be worse if white does not play d4 soon according with brief SF 12 analysis.
For sure it's one of the moves to be considered here, in Hiarcs14j.ctg (October update of subscription-book) there's ...Nxd5 only but with !?.
Cfish takes some time to bring it to first place in MultiPV=3, but after a little backward of your follow- up moves in depth 35 with Use NNUE Pure, it starts sticking to it (more or less constantly, with some short changes back to ...Nxd5 now and then once in a while)
Here's depth 48/63:
r2qk2r/3bbppp/3p1n2/n1pNp3/1p2P3/3P1N1P/BPP2PP1/R1BQ1RK1 b kq - 0 1
Good found of yours, even if a line leading to this won't be played very oftenly, didn't find a single game at chessbase online with Ajedrecista's opening moves after 13.Nd5.

I see, if I got Judith Polgar right, it was something somebody showed to her once in while before as an idea of LC0, as for the side line with ...Nb3.
In the game h3 wasn't played, c3 instead of Nc3 e.g.
Found another one YouTube to the game:

Thank you for the source. Answering Peter, my intention was giving a sequence of moves that reaches the position although any transposition of the sequence could be valid, so my line was a proposed line whose moves where suitable of change in order. The order of moves given in the video is the same than my proposal until 8.- ..., Bd7. Then: 9.- Nc3, Na5; 10.- axb5, axb5; 11.- Ba2, c5; 12.- h3 returning to my proposal.
Looking at the actual game: 33.- ..., Qd7 seems the only chance to fight for a draw, but 33.- ..., Rc7? was played instead. The finish of the game was smart.
