I was wondering why do most grandmasters never start with e2-e4

Carlsen, Anand, and Topalov all open mainly with 1.e4.  Who doesn't?

NIgel Short opengs exclusively with 1.e4, and has done so his whole career, he played a match for the WC crown.

Michael Adams plays exclusively 1.e4.

Anand, world champion plays 1.e4.
Carlsen, ranked the highest in the world plays 1.e4.

Kramnik plays 1.e4 and he regularely transposes into 1.e4 openings with his 1. Nf3.

To summarise, drugs are bad, mmkay?

Yes. I definitely see what you mean, as most of the games from Grandmasters I like to watch, are almost exclusively 1. d4. As stated above, some play 1. e4, but lately it's like a majority of the top Grandmasters are playing 1. d4. But the great ones start trends. We're in a trend- d4 is in vogue.

Dynamic attacking players still favour 1.e4.  I don't think things have changed all that much.

=o I thought Kramnik mainly opened with 1.d4-He specializes

Anyhow, 1.e4 is just as good as 1.d4. The reason Anand opened with 1.d4 in the WC is that he wanted to get into a Catalan, taking Topalov out of his comfort zone. Otherwise, Anand's mainly an e4 player.

Not too sure about Topalov but I think he plays both.

Kramniks openings as white.

1.d4    447

1. Nf3   380

1. e4   208

1.c4   34

1. b3 2

So he's hardly mainly a 1.e4 player, but he does play it. And out of all openings, the one defence he has played the most against as white is the Sicilian.

At the highest levels, "fashion" plays a large role in what is played.  The top players will explore a few variations which draw their interest.  This doesn't mean they are  the "best" moves, just the ones which are currently being "discussed" over the board.  Over time, the investigations move on to completely different opening sequences.

Well, as I pointed out in another thread, I recently downloaded the 20 newest twics pgns which represents the best games played ont the planet, and e4 openings lead d4 by something like 16,000 to 12,000. So, MOST good players still start e4.

i always see this opening 

i see this opening alot

Haadi1, in that last diagram, 2...e5!? is a very bold pawn sac.  Why doesn't white just take the pawn?

the reason why grandmasters don't play e4 is the really strong c5 sicilian. a reason why white wins is because black blundered during the game.

riga, cuzi think black would reply wit Bd6 and then hed be ahead in development 

The way I see it, just one development tempo isn't nearly enough compensation for the pawn.
