The game analysis says my move was a blunder but i can't see how. To make things worse the suggested best move is to take the bishop but it ends there, there are no more moves suggested which is also odd.
Anyway my question to you all is how is my move (highlighted in red) a blunder or even a mistake? The suggested move would be a massive blunder, why would i sacrifice a queen for a bishop, can anyone see the benefit of this suggestion or even why my move is deemed as a blunder.
