Chess School Quiz Challenge #12

Challenge
The black knight on b2 is trapped. Now Sarah Papp just has to capture it. How does that work?
Solution
White cannot capture the knight immediately. Then the white queen would be lost: 1.Bc1xb2?? Qc4xe2.
First moving the white queen out of the black queen's influence doesn't work. After, for example, 1. Qe2-f3, the black knight escapes via a4.
In fact, there is only one move for White that leads to the loss of the black knight. Sarah Papp found it at the German Masters 2023: 1.Be2-f3! Now 2.Bc1xb2 threatens, and Black has no defense against it. After 1...Bc8xh3, White would move the attacked rook to the side, 2.Rf1-e1, and on the next move White captures the knight.
