Yeah, I've not gone through it with an engine as yet. Queens coming off is always an agonising decision. There is no hard and fast rule either, its often a judgement call - style comes into it as well.
The opening is an interesting one... I was actually playing for something else (that Simon Williams has done videos on) but we ended up in a position I'm familiar with.
I couldn't really play the Scandinavian again as you'd have booked up from our friendly. I often open with d6 against e4 or d4. I like to keep it simple.
