When did 1400 USCF equal a strong class B player?
If you've looked at my tournament history and not just rating, I haven't entered a tournament in the last three months.. My coach thinks I'm at the upper end of class B level. The thing is though, I'm not entering any rated events because I'm doing a "breakout tournament" strategy. So my USCF is not an accurate representation at the moment.


Just use whichever you want. At a 1400 level, or an 1800 level, or a 2200 level, the better player will usually win.
You should open with whatever you're comfortable with. If you get lucky and your opponent is not comfortable with that game you might get a competitive advantage.
I don't think there's a reason to choose 1.e4 or 1.d4 as better or worse. They're both fine.
Fischer said 1.e4 is "best by test". But Kasparov said that all the top players are playing 1.d4 because 1.e4 and you get yawn another draw.
