Comments
Keep up the great work.
One way is to use an opening book like NCO and play out the moves to the end of a mainline variation or a branch with several choices.
Informants have small opening treatises in them now - taking a position from an Informant would work too, or any position from a recent master game that seems to indicate modern theory is fun as well.
Any reasonable method will work.
