I'll expand on my third point. With less than two strikes, you're not up there to swing at any strike. You're looking for a pitch that you can drive.
I'll use myself as an example. Back when I played in MSBL (it was 30 & over back then), I couldn't do anything productive with an inside pitch that wasn't low. So with less than two strikes, I didn't swing at them. I figured I had a better chance of the umpire calling it a ball than doing anything productive with it. With two strikes, my best likely outcome was a foul ball. I had to swing at them. I was looking for an outside pitch, which I could drive.
Everyone has strengths and weaknesses as far as location is concerned. Admittedly, the best hitters have more strengths than weaknesses.
