Who thinks 1. a3 is the most WORST opening in chess. There is no point in doing that stupid move. I have called it Idiot Defence. Comment if you agree that its the most stupidest move you could ever do in chess.
I dont think it's the worst. Bur I don't think it's very strong. Sometimes I play 1. a4 trying for 2. Ra3! and developing my rook early on. But I usually start (as white) with 1. e4.
Nh3, Na3 both have f3 and c3, or g3 Nf4, b3 Nc4 etc. and at least you have made yourself a game plan (...)
The plan being to develop a knight in three moves instead of one to reach an inferior square. But of course, in bullet, it gives you the next three moves to play without thinking, so it wins time which is the only important factor.
1.a3 can transpose to "real" openings, and that's the whole idea of it - not 2.b4 crap or that kind of stuff.
No. You probably don't know anything.
