1. Nf3
The best opening for Atomic Chess. It attacks the double-attack-sured-mate on Ne5. You can avoid that (the best move) with 1. f6.
1. e5
Hmmmmm, this not's good for the two. It not is the best, and if black replies with 1. e6, is a 5-move-mate-sured for white. (1.e4 1. e5 2.Qh5 2. 2. g6 3.Qh3 3. f5 4.exf5 4. Kf7 5.Qe6+ 5. Kg7 6.Qxg8#)
1. Nh3
So, if you're black and white starts with the Nh3, you need know the theory.
==How to reply==
Ok so, when white start with this, follow attacking and protecting with pawns. Reply H6, and maybe the opponent will attack the 5-move-mate or the 3MM. On that case reply with e6. 3.d4, 3, Na6, 4. Qh5, 4. g6 5. Qb5 and 5. c6. Maybe the opponent will reply capturing on b7, causing the explosion of a bishop, knight rook and a pawn. White will get advantage, but at the least are a little advantage.
