they scandi? woah it look strange, I've got questions!
The Centre-Counter/Scandinavian is one opening I like a lot, although I don't play it often.
You're right in that it allows white to attack black's queen in the 2...Qxd5 variation, but this is only for one turn, if black plays 3...Qa5. It does "break" that principle, letting white develop with tempo, so it's not totally principled, but that doesn't mean it's not a totally playable opening.
Furthermore, black often plays 2...Nf6, which means that black will be able to recapture with the knight and put it on a decent square.
I would say that Chin of Quinn gave decent variations - that's typically how you want to play the CC.
That's why, if asked, most people would say that 1...e5 is "better", but remember that this is only the very very start of the game.
