e4
What is your top 1 opening 🤔 ✨️ in chess

e4 is the most popular first move.
It has a lot of good points but isn't perfect.
One of the good points is to discourage black's knight from coming out right away to f6.
Which is black's most popular first move by far. And most important move.
e4 is the one move by white that will confound that knight.
Players with black just don't want to reply to e4 with Nf6 and see their knight bumped by e5.

I knew I wouldn't get away with trying to be helpful.

C4,D4 and E4 ….. are the old style openings. B4 is the modern opening with the recent modification added.

vienna
Yes.
A way to 'mess up' players wanting Philidor's defense.
Including the Vienna gambit. Which is like a King's gambit delayed by a move.

That K-side fianchetto with the Dutch is called the Leningrad Dutch isn't it?
In the Dutch - black often plays his Queen to e8 so it can come out on that diagonal onto white's Kside.
Doesn't he?
But g6 is going to block that.
Analagous to when white plays b3 in the Queen's gambit and related.
White therefore is blocked from playing his Queen to a4 or to b3 - often a key square for the white Queen.

Do you mean h8?

Ooh, I get what you mean. Queen to e8.
In this case it's really optional, you can create an advantage in the center anyway without needing to attack the white king with Nbd7 and e5

Sorry I meant the black Queen. I'll edit my post.
The black Queen goes to e8.
Because from d8 - g5 and h4 are controlled by white's very important knight at f3.
So that diagonal's not so hot for black.

I never really got into the Dutch and the Byrd much - but many years ago when I looked at those openings in opening books and articles - I saw that the Queen is often bumped over a square so it can diagonally deploy on that side of the board.
Regarding fianchettoes at g2 and g7 - woe betide the player who underestimates those 'beast' bishops.
But even with good play against them those bishops get extra-nasty anyway.
You see GM games where such bish's dominate play.
The two f-bishops are so often the big pieces of the 8 minor pieces.
Yes its generalizing.
Other patterns I've noticed over the years are that the opening in general is so often the biggest stumbling block for players wishing to improve and that bishop placement and understanding it well is the hardest thing in openings.
