What do you like the most among the e4 openings?

Petroff or French, but the former I only play the Black side of.

I don't play e4 as White. Only e4 openings I play as White are the Modern and the French (1.d4 e6 2.e4 or 1.d4 g6 2.e4). I do play 1.d4 d6 2.e4, but after 2...Nf6, I play 3.f3, leading to an old Indian after an early ...e5 or the Kings Indian Saemisch after 3...g6 4.c4.

Italian and Scotch, but I'm trying the Ponziani

Technically, 1.e4 is simply much easier for me to play than 1.d4. I only play the Danish Gambit, the Scotch Gambit, or the Goring Gambit. These openings are very chaotic and the pieces have great freedom to move about the board. And NO---neither the Sorenson or the Schlechter refutes the Danish; they just result in a game that is largely shorn of its flash and dash, especially the Schlechter.

g3 vienna.

Is the schlechter the one where the Queen's get traded? That's what I play and White has nothing.

1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 d5 6.Bxd5 Nf6 7.Bxf7+ Kxf7 8.Qxd8 Bb4+ 9.Qd2 Bxd2+ 10.Nxd2 and at a normal, over the board time control, a draw is easier for Black than putting his underwear on.

The Scotch Gambit is impossible against what I play, and the Goring Gambit is nothing either.

i love the bongcloud

and also the king's david opening lolololol, and seriously, i love the halloween gambit and guico piano game, and traxler and fried liver attack and sicillian, BUT IF MOST, it is halloween gambit

Thriller---

The Schlechter is the early Queen trade where black has a 3v1 queen-side pawn majority and white has a 4 v 2 king-side pawn majority. I prefer the double-pawn sacrifice Scotch Gambit and the double-pawn sacrifice Goring Gambit. These are all I play, they are "kitchen-sink openings" where white throws the kitchen sink at black and either wins big, in the style of the 19th century, or loses badly, there is hardly any in-between. I prefer that type of chess and am perfectly happy with the risk. I care not a wit for the win-rate. It matters to me how I win, not simply that I win. The Danish is style and symbolism, all gambits are. They are the very definition of uncompromising commitment. When you win, you drink wine with the Gods on Olympus; when you lose its destiny, doom, and the fate of creative over-reach. Win or lose, it's with style. Thank you for your input.

Well, You'd never get a Double-Scotch Gambit against me. After 1.e4 e5 2.Nf3, I play 2...Nf6, so if 3.d4, I play 3...Nxe4, and if you try to do 2.d4 exd4 and only then 3.Nf3, then 3...Bb4+, avoiding any ...Nc6 transposition.

Ethan--- there are at least three Schlechter defensive lines in chess, they are for the Danish Gambit, the Slav and the French. What is being discussed above is the Schlechter line vs the Danish Gambit which results in both queens being removed early resulting in a very asymmetrical position. If you meet 1.e4 with e5 as black it is well-worth knowing, it greatly slows down the Danish Gambit, but the resulting position is difficult for both players. The Sorensen is the other, more popular way to meet the Danish, instead of exchanging queens early, black throws out an early d5, resulting in a fight on the d and e-files that between them have only a single pawn. A near-totally open board--get there first with more.

Thriller--

I recognize both the lines you list because the Danish is a branch of the Center Game, and the other is a Petrov line. I do try and transpose into the Scotch / Goring just like I do the Morra, rather than play them from the start Both the lines you list lead to wide-open games while simultaneously leading the game away from what was the expected outcome after 5 or 6 moves.

Sicilian Najdorf.

Go big, or go home.

For black the odd sicilians are good.
As white I like the accelerated panov, which plays like a Scandinavian half the time... I also like facing the Scandinavian. The Vienna Meisis also just plays well for white. 
The Sicilian is good for white if white knows the theory very well, but it's an enormous amount. 
Black can always get the game he wants via the french, it's just a game that also plays very well for white, so it's fine. 
Really all the lines seem to play naturally for white, but you're banging your head against a wall nonetheless due to how played out it is. The key is finding ways to around that problem.
My solution is just to play the Van Geet, which is alot like e4. But I do long to play the Scandi / Panov rather than the Jobava or the Closed Scandinavian. Maybe one day I'll buckle down on the Sicilian theory and revisit e4.

That's still wrong. The abbreviated name is Scandi.
