1. Nf3 f6 2. e3 e6 3. Nd4 Bb4 4. c3 f5 5. Qh5+ g6 6. Nb5 Qh4 7. Qxh4 Nf6 8. f3 Ne4 9. fxe4 O-O 10. Nxa7 Bd6 is a draw with perfect play from both sides. Opabinia2401 often plays 9... a6 after which black should lose, but it's messy and white really needs to know what's going on to win. 9... a6 10. Nxc7 Bd6 11. g3 O-O 12. Bc4 f4 13. Rf1 for is the correct line iirc.
White is able to avoid all of these lines however by playing 5. Nb5 Qh4 6. g3 Nf6 7. d3 Qh5 8. f3, which is a bit tricky, but should be a win with proper play.
These drawn lines can also come out of 1. Nf3 f6 2. e3 e6 3. Nd4 f5 4. Qh5+ g6 5. Qh4 Qxh4 6. Nb5 Bb4 7. c3, but white can sidestep them there as well by playing 7. Nc3. As a general rule, if the queens are off or will quickly come off you should block a Bb4 or Bb5 attack with Nc3 or Nc6 respectively where possible, and if the queens are going to remain on you block with the pawn when possible.
Also the version of stockfish that lichess currently uses for atomic analysis is not the best. The most recent versions have some pretty bad bugs in their evaluations. As a result I've been using a version from early november in 2019 for personal analysis for quite some time now. If you want something actively developed though can download fairy stockfish, which recently added support for atomic. I have heard it's supposed to be better than the version of stockfish I'm using personally, but I haven't bothered to test things extensively myself.
i tried this line against opabinia2401 who is #3 in atomic blitz and they smashed me in quite a few games while playing as black. so i ran this position through an engine to see how i could have survived, or even won. at first the computer thinks white is doing quite well, but then it led me down the following path:
after these moves were input the computer says the position is basically equal, and this is only after precise play from white, routing the knight into a useful position just in time.
what do you think? would you want to play this line as white? is this a good response to the popular 1.Nf3 2.e3 line?
