Well I could reveal a few lines of my prep then.
atomic chess opening book?
Sort:
After 1.Nf3 f6 2.e3 e6 3.Nc3 Bb4 4.Nd4 a cool move is 4...Nc6!! the idea is that 5.Ndb5 Nd4 is good for Black. This was a common line on ICC back in the early 2000s!
One of the openings you would always want to start with is Nf3, as it tends to be a very strong move with great outcomes. After this, black has three moves to survive the upcoming moves: f6, e5, or d6. The best move is for black would be f6, as the other moves tend to put black at a huge material disadvantage. White would then open up the Queen and the Bishop by doing e3, another great move. This is where beginners tend to trip up. They have to block the upcoming knight and queen, otherwise, they'd be in a huge material disadvantage or checkmate. As black, after this always go for e6 or d5 (if you're not sure of any follow-ups, use e6). This is pretty much how you always want to start a game until you become more advanced and know other tricks and shenanigans to mess up your opponent. Tell me if you want me to say some more.
The oppening that i love
Why would they do 2... d5? It's more probably that experienced players would rather use Nf6 because that puts them in the offensive and defends themselves from Qg4 and Qh5. At the beginning, it is easy to see why black would defend against Nc3 with c6, but the better more for black would actually be e6.
more of a lethal pin person myself
tbh that's probably not going to work
stockfishhunting with white:
leads to
and now a4 instead of a3. Stockfish always takes on f2 anyway, and the advanced a pawn can help shutting in black's bishop, later. eventually. perhaps.
After playing Bb5 and rook c1 we reach
attack ideas for white are 12f4 (response to g5) potentially opening up the f file or the rook later.
exf, and f5 (either planing fx (plan is to targeting the pinned d pawn with the rook after getting rid of black's two remaining piece) or f6 (going for the much less complicated pawn promotion. Bc4 will clear the path for f7, after which white moves only the the rook until Rh8+.)
d5,d6 (pinning the d pawn turning it into a target for rooksacrifice as well as preventing black's bishop from blocking the f file, should we open it up),
Rc7, in response to cxBb5 (shutting in bishop and rook for good,
as well as Rf7+, planing to sacrifice on d7 at some point.
honourable mentions:
13d6 (preventing white from advancin to d6) can be met with Bb5xc, stockfish will then take the knight on h and after Rc7 the endgame should be easily winable.
11Ne7 (planing to close the c file if we take with the bishop on c, also preventing our d-pawn push) can be met with 12d7 anyway, after Nxd7, 13Nf8, 14epawnpush and 15Nd7 usually leads to an endgame where white is up the h-file rook or quality.
The main purpose of this opening is to distinguish human players from stockfishzombies.
The latter are usually completly unable to explain why they played the moves they did from their 12th move (what is the plan and why that choice of plan?) onward.
As an added bonus this might help white beat a stockfish-abuser either on time in bullet&3/2 (some variants have a lot of moves...) or by mate, should they go for the "second best" move at any point.
One of these comments says d6 is a move after nf3. This is incorrect, as you can just play Ne5, forcing the opponent to move their f pawn, and after they move it, you have Nd6, and the opponents bishop can't move and you will capture their king
The solution to white playing nf3 is black plays e5. it prevents the knight from moving queen side. If knight pushes king side, just dodge.
I think this is the most effective strategy in combatting nf3
In fact, this is my favorite opening that I developed. I am allowed to name it lol? 
Anyway:
However, it can be defeated by Qa4 or Be3. So, a variation of my own strat is:
Hence, Black leads with a material advantage that is basically forced.
Hopefully this helps someone. Let me know if you have any other variations or suggestions
Not sure how old this, Jb_labs, but it seems like the entire line in 2/3 are moot. after 4. g3, wont the best move just be qd4, attacking the d2 and f2 pawns? White's not going to move their knight up like that because it's just giving black a free win.

Unfortunately, after white plays g3, if black plays Qd4, white can play Ne5 to capture Queen. I learned that the hard way.
Your absolutely right, however, that an experienced player would not fall for it. There is an excellent countermove to it in Lichess. However, most don't know it and it can throw people off when you allow the knight to advance that most people just do
I'll admit it's more a gambit but I think it's a fun one.
The real opening for atomic imo is the following:
This move will almost guarantees black loses the knight, but better than losing a corner.
The smartest move for white after black plays Nc6 will be to play Nf5, then Nd6, forcing black to capture with either pawn or bishop, otherwise risking losing. This does weaken blacks defense a bit, but I can't think of anything else really.

A variation could be:
Preventing white the chance to play Nf5.
Let me know any other ideas
Oh wow, I don't know how I was completely blind to the knight taking the pawn/queen there.
since atomic chess is the third most popular varient, why not create an opening book?
Nxf2# newbie's mate??? ideas pls
