We messed around with this about a year ago and we actually thought it was better for Classic than Empowered, though clearly that isn't bearing itself out to be true right now!
Our impression was that queen is probably very important. The thing I've most wanted to try (though I haven't had the opportunity to test it extensively) is just getting that out ASAP. Afterwards, no idea, but classic would be looking to pressure a decent queen trade.
Anyway yeah I don't know that I'd mess with the knight move. d5 seems ok, but instead of nc6, why not qd6?
