Gaviota wants to play after 2 min Nxc6, which is also good. It wins the exchange
at least after bxc6 and Ba6 or after 1 ... Qxc6 2. Bb5
But of course Ne6 is better!!!
I did a fast forward in the position to see a line 1. Ne6 fxe6 2. Qd1 Ne7 3. Qh5
Kg7 (Qxh6 was the threat) and now... this is what Gaviota wants to play

4.Bh7!! is gorgeous, but the "human" line that is not showing is
4. Bh7!! Bd7
5. Rxe7+ Bxe7
6. Qg6+ Kh8
7. Bg8!! and if Rxg8
8. Qh6#
And as we say in Argentina with a finish like this: "This is a painting"
Should be frame it?
Unfortunately, this lines are never shown in PV line analysis or in computer
games, because the other side tries to avoid it.
The final position deserves a diagram:

PS: I think that this position with a pawn in a6 (to avoid other winning
lines)could be a good test position.
