Karjakin often plays 1.e4 and is the new challenger to the world title. Fischer almost always played it. Many super GMs and GMs play it.
Why do people keep playing e4?

1.e4 isn't a bad first move. The history of chess is proof of that. Many beginning players start off 1.d4, because it leads to slower (less tactical, closed positions) games, but 1.e4 produces real live games that are challenging and well worth the time. The only problem with 1.e4 (and it's not a real problem) is that it's a well studied opening, but this is more of a concern for players in the 2000 rating range and up; below 2000 a player hasn't got to worry as much about facing a well prepared foe, armed with 1.e4 theory to the teeth.

There's nothing wrong with it. Fischer did call it best by test and as far a Kasparov and almost all GMs can tell it is!

In this page, written in 2014 (paragraph 6. The World Championship test) you can see stats relative to e4 and d4 at World Championships starting from year 2000 (link: en.chessbase.com/post/1-e4-or-1-d4-which-is-the-better-move)
The results are (for white):
e4: used 25 times
1 win 4%
3 losses 12%
21 draws 84%
d4:used 62 times
18 wins 29%
6 losses 9%
38 draws 61%
I think everybody with something inside his head can realize what these stats mean: GMs use e4 less than d4; and when they do, they get better results with d4.
ERGO, E4 IS WORSE THAN D4.

i really love e4 and italian game.
i use Gioco Piano very very often, is very difensive and closed , i like it.

I love when people make these statements. I just looked up Magnus Carlsen's most recent openings as white. The most common he has played were e4 openings (against Sicilan and the Ruy Lopez). But I guess he's just a "noob."

I love the Italian game, too, especially the Scotch Gambit.

Fun fact: Carlsen can make every drawish position a win.
But that's because he is Carlsen.
If you play e4, you're gonna lose a lot of points.
I thought I heard, maybe on one of the Candidates broadcasts, that there was a recent Spassky interview and he said that later (maybe in 92?), he discussed 1. d4 v. 1.e4 with Fischer and they generally agreed that 1.d4 had an advantage as it was already protected.
I haven't bothered to confirm it or maybe I heard wrong. But if true, it is interesting.

BEST BY TEST!!!!! FISCHER SAYS AND IS RIGHT!!!!
Please, no tests; I hate tests; everybody just play chess, now that's more fun...

After some years playing chess, I have realized that one of the most common opening moves, specially among patzers, is 1 e4.
I'm pretty concerned about the fact that people keep playing one of the worst possible moves to start the game. That's why I decided to expose the reasons why e4?? is a bad move. Hopefully, I will manage to enlighten a noob or two.
By playing e4?? you throw to the bin the small advantage you have if you play white. You may be wondering: how is that possible? Well, I'm just about to explain.
The three most common answers to e4 (and the best two; seriously, don't tell me that the Scandinavian or the Alekhine are good, or I'll go hunt you) are without a shadow of a doubt e5, c5 and e6.
If your opponent plays e5, you're probably going into an Italian game or a Ruy López. If you didnt know, the Italian game is also called the Gioco Piano, and is known for being drawish. If you end up playing the Ruy López, then you will play the most boring opening ever aka the Berlin wall, and yes, that's drawish too.
If your opponent plays c5, you're gonna suffer. A LOT. The game will be sharp, and as you may probably know, the opponent is always smarter than you, so he'll take the win easily.
If your opponent plays e6, then you're about to play against the French Defense. I wish you luck. If you aren't one of those cowards who play the Exchange Variation, your centre pawns are about to get swept.
After this brief explanation on why e4?? is such a bad move, let me recommend you some alternatives for you patzers to try.
Those are: d4, c4 and Nf3.
The problem is that patzers don't usually like positional playing so I don't know if you will be good with this openings.
If you refuse to pay attention to my advice, then stick to your drawish e4?? and keep on drawing or losing. Or even better, leave chess.
Hey, delete this trashy thread, Im the only one that can troll here, this argumment doesnt make you go mad because of the trolling, but because you are a down kid only rated1350 on standard saying the move of the brave is a patzer move. I could beat you with my eyes closed playing 1.e4, you know, I could beat you by even playing 1.a3
Also, regarding your best answers to 1.e4, the French is not the best answer, but hey, you are a Spaniard without job that comes here and wastes his life making trashy non trolly posts. When whitep plays 1.e4 he always has a +.30 advantage or something like that if he follows the mainlines. But when white plays 1.d4 and black goes for the Nimzo, even when declined with 3.Nf3 the advantage according to engines its of about +.17
1.e4 is the best move.
Well, in the first sentence of your post you say that you're the only one who can troll here, so you make it clear for everybody why you came to this thread.
The fact that you have no life and spend time criticising others is only one of the beautiful aspects of your personality.
As for the personal attack saying I'm just a Spaniard without job, I can only answer that you don't even know if I have a job or not, or if i am old enough to get one. Also, it seems to me that you said "Spaniard" in a disrespectful way, and that's pathetic, taking into account you're Mexican, and Spain (along with many more countries) is a million times better than Mexico (may Trump do something about that).
