Yeah they're definately harder in blitz it's not you.
Also I've been playing D4 I feel like it's Definately way more smooth than the E4 opening. It just flows so much better.
Learn E4 so you know what to expect when it's played against you, and once you get a good grasp swap over to D4
nah for life
I play and look how high my blitz is
you're 2339 BULLET. % of people don't have 2339 BULLET.
blitz chess ratings being lower than rapid ratings have NOTHING to do with the opening, (unless you play a very bad opening). The reason it's lower than the rapid rating by a lot is because the skill level if naturally lower if you have less time to think.
