Looks like a blunder to me, not a sac. If it is a sac, it is the worst one ever.
Queen Sac question
Sort:
Probably not. If you go to the analysis board, you will see the evaluation rises from 2.5 to 4.2, I would consider it to be a blunder, or at least a mistake. You just failed to keep the advantage from this blunder
