Yes, it was clearly my failure to not think of this transposition, and I was
unhappy with it. But fixing it was easy as I simply had to add 3. ... exd 4. Nc3
c6 :)

From another post I just read I am not sure if you have understood me correctly.
My point is that in a situation not considered before the game I'd usually
prefer having no bookmove at all than some bookmove taken from a GM game
unchecked, so this is the lesser evil in my opinion. Thinking about it, this one
could be tested easily - would only take some time.
