Why is this a great move?

So I was doing a puzzle and got this position - it says that this is winning a queen for Black. Could someone please explain why? I did an analysis but blacks queen can easily escape. What am I missing?

I'm guessing it wants to sac the queen by playing BxB.

B+N for a queen = loss of 3.
If queen moves away and you lose bishop also = loss of 3.
But I guess overall white's activity is better without the queen.

For tactical purposes it doesn't really matter, either way Na5 wins material.

Yeah, it seems more to me that it wins a bishop than winning a queen. I guess the coach tip may have been incorrect?

It's incorrect in the sense that it does a poor job explaining the position. If I were white in that game I would probably have Bxe6 as my top candidate move after a few seconds of thought (I would give up the queen). But at that point it's not really a tactical puzzle because white is taking other things into account.

It should probably say Na5 removes the defender from d5. That's the important tactical theme (removing the defender) and so black wins a bishop (even though giving up the bishop is technically not the best move).

A puzzle in a book? Or on chess.com? On another website?

"It says" - who is that "it"?

You attack the queen and defend the ♟️ on b7. The queen doesn’t have a safe square that defends the bishop. White is forced to move the queen, allowing Bxd5 and setting up Bxh1 on the next turn.
