"All openings 99% of the time if the opponent knows what they are doing equalize."
This statement is completely false. Grandmasters have around twice as much wins with white as with black. If what you said was true you would expect them both to be about equal. In fact the higher up you go in rating the more of an advantage playing as white is.
Chess openings are about getting a lasting advantage - not a win but an easier game for while and a harder game for black. The Colle, London - every opening.
Also I can assure you Alekhine, Euwe, "Grenfeld", and Capablanca did not regularly play 1. d4 2. Nf3 3. e3, only maybe occasionally as a surprise.
My statement is totally true. Might come as a shock to you on a forum dedicated to openings but … yes it is true.
Can show me an opening with a win rate at 50% . While you are at it… show me an opening line that Black can’t not equalize .. with the aid of stockfish, I’ll show the equalization, or a transposition that leads to equality. Either way that debunks your premise!

John Cox’s (an established Chess author and titled player 2400+ FIDE) from his work titled “Dealing with d4 deviations” “In the 1930s the top guys didn’t know whether these openings or the Queen’s Gambit were better. These were the 2700s of their day; they understood chess a lot better than I do (I.e. a modern 2400 FIDE rated player)
Let’s roll with some stats on openings that have 1. d4 2. Nf3 3. e3 with the first couple of moves
From Chessgames.com
Queen's Gambit Declined Slav (D12)
1 d4 d5 2 Nf3 c6 3 e3 Nf6 4 c4 Bf5 It’s popularity.. the 1920s and 30s and 2000s
In the 1920s and 1930s. There you find Alekhine, Colle, Grunfeld, Bogoljubov etc etc essaying it multiple times.
Queen's Gambit Declined Semi-Slav (D45)
1 d4 d5 2 Nf3 e6 3 e3 Nf6 4 c4 c6 5 Nc3 it’s popularity, peaked in the 1940s and in the 2000s.
Pre WWII they didn’t play 1. d4 2. Nf3 3. e3 with the sole intent of playing a color’s reversed Meran i.e. the Colle ( Koltanowski or the Zuckertort )
How about something a little more modern say the KID ??
Some popular lines back then...
1. d4 Nf6 2. Nf3 g6 3. c4 Bg7 4. Nc3 O-O 5. e3 d6 6. Be2 Nbd7 7. O-O e5 8. Qc2 Re8 9. b3
1. d4 Nf6 2. Nf3 g6 3. c4 Bg7 4. Nc3 O-O 5. e3 d6 6. Be2 Nbd7 7. O-O e5 8. b4 Re8 9. Bb2
These are old lines and old ideas from a bygone era...
Yes... they leads to equality for Black.. That said... no lines have been discovered that give Black an advantage. White just moved on to bigger and better ideas.
I should just be quiet ... OTB I've scored very well with these or a variation of them.
The point in all this... is that one doesn't have to play the latest and greatest GM main lines ... by doing some homework, pulling from master games from a different era, one can come up with what appears to be new ideas over the board... (maybe with the help of a chess engine improve on the idea)
Perhaps, currently an opening might be equal, but someone might discover a novelty that keeps the pressure on black. An opening that is equal in the eyes of an engine does not translate to actually equalizing on the board, I think the both of you are approaching this with opposite perspectives.
