Why does the engine tell me to sacrifice a queen for bishop after a failed Scholar's mate? I am a beginner. Recently I have looked at the computer-generated analysis of one of my games and I found a surprising recommendation. Why is it best to sacrifice my Queen in this situation, as the screenshot shows?

It's basically a trade. After you take the bishop, if the opponent takes your queen with the knight, then your bishop is no longer blocked by the knight and you can take their queen too. The advantage here is that after the trade, the opponent's king will have to take your bishop, and thus can no longer castle.
