I played the KIA as a beginner as well.
I used the 1.e4 move order.
I know a lot of people in thread has been mentioning the 1.Nf3 move order, but you don’t have to play it with Nf3.
You can play it with 1.e4 move order.
It is how Bobby Fischer played it.
"X opening is a draw because engines" is the stupidest argument I've ever heard. Are you stockfish? Is your opponent stockfish? The only requirements you should have at 1200 when picking an opening is
1. Does it instantly lose?
2. Do you enjoy playing positions that arise from the opening?
I've played 1.Nf3 followed by a KIA setup for a year and a half straight. I won most of my games. People prepped for me, it didn't matter. It didn't lose, and I enjoyed playing it.
