Answers.Text: I am curious how White intends to continue after 9...Qd8 (or even 9...Qd7) in the first line. Is he going to sack the d4-pawn ? To allow a knight exchange ? You are probably true that White can get some advantage somehow in this line, but there seems to be an important decision to be made at move 10 - just when the line ends, alas.

Answers.Text: The knight exchange only assissts White's development, so there is no reason to prevent it. Be5 holds the d-pawn. Only thing to note is O-O-O by White is not yet possible due to ...Bg4.

Answers.Text: @Evargalo I just checked with an engine and sacrificing the d-pawn seems to be very good for White aswell. I have added both lines.

Body: <p>As a person(~2170 uscf) who has recently started playing the scandinavian defense(Qd6), and has played against the scandinavian defense on the white side, I find it hard to get any sort of meaningful edge as white and often pretty much equalize with black. Yet in the top level, it's rarely seen in classical chess. Thus, it seems that there should be particular variations in the Qa5, Qd6, and Qd8 scandinavians that put it out of business. What are these lines?</p>
