Hmmm of course you broke it well done. I mean I have a long ways to go. What about 5. Bd6 threatening a similar mate and inter posing any help from black’s queen?
Brilliant Move

Also sorry for posting without thoroughly checking that the notation / squares were correct. It’s not helpful to anyone.
1. Qxh7+ Ke8 2. Bd6 (interposes ...Qc3 defense) Kd8 3. Qe7+ kc8 4. Qc7#
I may have overlooked a defense please feel free to refute. Also there is still ...Qxf2+ if black wants to delay this as well.

Sorry, I still don't see it. Here is one sequence that leads to mate: 1...f6 2.Bxf6 Re7 3.Bxe7 Kf7? 4.Qxh7+ Ke8 5.Bf6 Qa3 6.d6! because whites B covers a1. But what if after 1...f6 2.Bxf6 Re7 3.Bxe7 black simply plays 3....Qb2? Or better yet, 3...Qxb3 and then after the rook moves, 4...Qb2? Sorry if I'm a little slow here.
4. ...Qb2 is this in your opinion black’s best candidate move? I wanted to see what you would do as white assuming black does something strong as this. I feel a little lost. Whites rook is weak. There’s the back rank checkmate that prevents white’s rook from doing much in future lines. What are you hoping to achieve as white assuming checkmate really isn’t possible? Sooo often when I get a small advantage in the middlegame .. I’ll blow it 🤣

1...f6 2.Bxf6 Re7 3.Bxe7 Qxb3 4.Rc1 Qb2 then what? 5.Qg5 Kg7(or f7) or 5.d6 Qd4 and d7 is covered by the bishop. It's becoming clear to me that the bot called this "brilliant" because there is some really deep win that it didn't see on its previous search. Maybe h4-h5 and/or then Re1-e3-g3 ? or c5-c6 ? Maybe on ply 20 it queens a pawn, hehe. This position ended up a lot more interesting than I first thought.

Is a Brilliant move one that flips the -+ score > x, where x is some value above some arbitrary -- objective? -- point beyond Best?
Sorry, I don't follow your sequence. In the above position 1.Qh8+ is illegal.
You’re right! I meant Qxf7+, and updated the comment. Thanks.
That's illegal too. As is Bf7 in your above post.
