Answers.Body: <p>Without giving a long, drawn out explanation, the simple answer is that you're decreasing the mobility of the queen.

Answers.Text: If you play Qd3-> Qd2 then you've taken two moves to do what you could have done in one by just playing Qd2 in the first place, I'm not sure you're following what I'm saying. We're talking about the mobility of the queen on the d3 square.
