What first move would you play as white if you can't play or ?


The subject line makes no sense. You can't play "or"? So you are asking what we play as White if we can't play a coordinating conjunction?

I have played e4 & d4 far more than any other move in my chess career.
However, I have played a few different first moves in my time as opening training.
- Nf3
- b4
- b3
- e3
- g3
- a4
I think that might be it.
Thinking about it now - I am kind of shocked.
I have played thousands upon thousands of games.
Yet, I don’t think I have played every 1st move available to white.
I never felt the need too.
