Normally, White plays (after 0... h6) 1. Be3 Ng4 2. Bc1, when Black has gained tempi but weakened his kingside.
Suppose White plays 1. Bd2 instead. Instantly I see that I can play 1... Nc6, and I don't want to play 1... c5 because the bishop on d2 aids the defense of White's queenside.
My biggest concern with 1... Nc6 is 2. d5 Nd4 3. Bxh6 Bxh6 4. Qxd4. Do I have enough compensation for the bishop pair?
And are there better moves than 1... Nc6 or 1... c5? Maybe I can play 1... c5, 2... e5, gaining central space and eventually gaining an outpost should White play f2-f4.
