most people I play against will have played enough games to not spend over 40 seconds in the opening, even in confusing positions. You will have around a 20 second time advantage while being lost positionally
Introducing: The Thrawn Opening
to show how significant -1.5 is, I will show you that I win 89% of my rapid games when I am +1.5 at some point
This opening allows you to already know more than 10 of your first moves. The opponent will probably have to start thinking after the 3rd or 4th.
& the ruy lopez gives white an advantage & after 20 mins of studying you can also know your first ten moves
All right, you are saying the move order is e4 and then e3 and then c4 and then so forth
What about 1. e4 e5 2. d3 d5
Now what?
You're cooked
If they play normally & complete development like a normal person, within the first ten moves you have a significant disadvantage
Which is why there doesn’t always have to be the same order and as long as the MAJORITY of pieces are in correct places it works. If they do that you just have to take their pieces. And instead of moving king’s pawn you can just reverse most of the positions and move the queen’s instead.
If you rely too much on refining your openings, you will lose a lot. Even the most downright unorthodox openings can work if you know what you're doing; just look at Magnus Carlsen.
This opening is simply too passive to be effective; and I say that as a player whose main issue is that I don't play aggressively enough.
This opening not being simple is actually an ADVANTAGE as you KNOW your every move in EVERY match. You just have to get used to the opening and you will almost never run out of time anymore. Your opponent will still have to think a lot, you won’t.
