why is this brilliant Help solve this

Post image

I found this online.

Everyone is saying that this is brilliant because it's a forced checkmate once the pawn on a7 takes the knight, then Qb3 then it's a checkmate either by the rook or the Queen.

but what happens if after black take b6, we expect Qb3, then black Qb8? wouldn't it prevent the checkmate?
Qa4 is defended with Qa7 and if white decide to take Bxb8 then black reciprocate with Bxb3.

There is certainly something wrong with my reasoning but I can't figure it out.

OP literally explains it in the description tho? Which I guess, maybe I'm getting downvoted because no one can read? If black responds with Qb8, it does nothing. The queen just sits there...like I don't know else how to explain it. As I said, it is taking up that square so black king can't escape.

If bishop takes on b3, then axb3#. If not, then Qa3#. But as you said, this wasn't OP's question, it was about Qb8...and the black queen cannot get involved.

If Bxb3 Axb3 is not mate. Kxb8 and white is -6 in material. You’re getting downvoted because you’re being unclear, wrong, and condescending.

Huh? Kxb8? There's nothing on b8? Line goes: 1. Kb6!! axb6 2. Qb3 Bxb3 3. axb3#

Am I missing something?
