Capturing my opponents queen
Logic dictates that it is better to post a diagram like this (it takes some time to find a game manually), plus your screenshot is not complete, one whole rank is missing.
Anyway, inside a diagram there is an explanation. Basically you get material advantage (plus you have more active pieces along with the opponent's unsafe king). After your move, the opponent can play Ne3 and save his queen at least.
Hope this helps.
