I am learning the Pirc Defense as black. I am a bit confused when after 1.e4 d6 white plays 2.Nf3. Are they forcing me to transpose into a Sicilian with 2... c5? I kind of like the Sicilian Dragon, so I guess I could play that (if they play 3.d4). But I am still curious what is the best way to avoid the Sicilian?
[FEN ""]
1. e4 d6 2. Nf3
