personally i think most ppl already know that 1. nf3, f6, 2. e3, is the strongest opening but its boring to play
id say 1. nh3, h6, 2. d4, e6, 3. e4, works really well too
same with 1. nf3, f6, 2. nc3
theres a lot of strong openings but those are the top 3 for me
i usually dont use them tho since i like using lines ppl dont know very well instead of well known strong lines
I usually use 1. Nf3, f6 2. Nd4 or 1. Nh3. What is your best opening in atomic?
