When you refuse to take a queen

Is the computer here saying that my refusal to reveal check on the king to win a queen wasa blunder? I'm not interested in taking her highness out. I saw ten moves in with some variations on the side to attack the king and deliver mate. I believe a queen win should always be ignored in advent of a attacking a king. It's possible of course the computer sees something else was a blunder. Computers can think so deep so I'll need to analyse it. 

Whatever the blunder was, the analysis says it was executed with 96.8% proficiency. So this might be a case where the computer just didn't understand my motives by refusing the tactic to win the queen.

I suppose no one really knows. If only we could ask an AI.
