Question on the KID
He should have played ...d6 before to prevent this. I think the best move now is 4...Ng8.
Anyway, after 2.Nc3 it's not going to be a KID anymore. Most people would opt for 2...d5 to "punish" white's omission of c2-c4, but transposing to the Pirc is fine too -- if you play 2...d6 or 3...d6 to prevent e4-e5.
