A chess trap in the Scandinavian: +2.88 for White!


Ah yes, as a Qd8 Scandi player myself, I know this trap all too well. I even made a little rhyme to remind myself:
"If bishop and knight, pinning brings plight!"
As a beginner, I know you can play it, but I don't understand why the black would move the queen back and forth like that... At least Qa5 make some sense for me.
#6
3...Qa5, 3...Qd6, 3...Qd8 or even 3...Qe5+ or 3...Qd7 are all more or less equivalent: normally black at some point continues ...c6 and ...Qc7 anyway to reach a position like in the Caro-Kann.

When I play the Scandinavian, I always go for some spicy gambits. Such as the Kadas gambit and the Icelandic gambit.

People who play 3. ...Qd8 or 3. ...Qd6 will deserve all they get. They're both more difficult, even though theoretically about the same as Qa5. If someone's prepared for them with white, they could be in trouble. That's a trap that no decent player would fall for, of course.
Most decent players wouldn't fall for the trap, but they might not consider Ne5 when playing Bg4. White still has an advantage after 6...Be6 7. Bxe6 fxe6 8. 0-0 (or 8. d4).
