D4 is better than E4 and C4 and its also whatever works best for you

ya I know that there are 2 ways to tell what the best move is the Ret'i has highest win rate and d4 has the highest advantage

you know I think the real best move in the opening is your favorite move or the move you've done the most because you know it the best

for me that's queens gambit jobava London London and the dutch thing I do plus Benoni defense accepted

if you like E4 that's the best opening if you like f3 that's the best opening if you like d4 that's the best opening if you like g4 even that's the best opening

the reason the opening you like the most is the best opening is because you know the middlegame the best and that is the opening you know the tactics the best with thats what most people who are great at coaching will probably say


what proof
I have proof d4 is better E4 has 38% win rate white d4 has 39% win rate white and 0.33 advantage e4 is 0.25 advantage worse then the Ret'i 0.27 advantage

I will say that the kings pawn opening Queen's pawn opening The Ret'i and c4 give you 100% accurracy no matter what on the first move except insights
also the brilliant move puzzle answer is rxh7 wins a pawn and eventual mate
