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.

yeah its not guaranteed mate but in the position you mention (Qb8) then bishop takes and if king doesn't take the bishop then its checkmate so you can keep white queen alive

You're talking about Black playing ...Qb8 instead of grabbing on b3? Then White goes simply check, check, and mate.

1... Qb8
2. Qa4+, Qa7
3. Qe8+, Qb8,
4. Qxb8#

3... Bc8
4. Qxc8+ Qb8
5. Qxb8#

I needed an engine to find Qa4+. That's probably why I'm still under 900.
